The N73 (twelve cylinder) engine remains unchanged. The power output and torque of the engine has been significantly increased. For 2006 model year, a redesigned 4.8 literValvetronic engine replaces the 4.4 liter Valvetronic.This significant increase in displacement is the reason the vehicle is now badged 750i/Li instead of 745i/Li. The following Chart shows the difference in horsepower and torque between the two engines: Nm 520 480 460 420 380 340 300 - 260 kW PS 230 381 230 354 240 326 220 299 200 272 ISO 245 160 218 140 190 120 163 100 136 80 109 60 82 40 54 20 27 1000 2000 3000 4000 5000 6000 7000 1/min N62B48TU N62B44 7 E65/66 Model Update The major changes to the engine are: • Air intake duct • Differentiated intake system (DISA) • Crankshaft • Oil dipstick • Oil pump • Inlet and exhaust valves • Sparkplugs • DM E 9.2.2 Air Intake Duct The N62B48TU engine has a larger, two-channel air intake duct used for air intake. The use of two air boxes is solely for keeping the hood line low (aesthetics). N62B48TU Air Intake Duct Index Explanation Index Explanation 1 Raw air intake 3 Hot-film air-mass meter(HFM) 2 Intake silencer 4 Clean airflow to intake system 8 E65/66 Model Update Differentiated Intake System (DISA) The previous fully variable intake system (DISA) is no longer used in the N62B48TU engine. A two-stage intake system (DISA) is used instead. Differentiated Intake System (DISA) Index Explanation 1 Servomotor, cylinder bank 1 2 Differential pressure sensor 3 Servomotor, cylinder bank 2 4 Bores for fuel injectors 9 E65/66 Model Update Operation of Dual Stage DISA System In the intake system a sliding sleeve (3) is located at the intake manifold for each cylinder. The position of the sleeves determines whether the intake passage is long (1) or short (2). Index Explanation Index Explanation 1 Long intake passage 3 Direction of movement of sliding sleeves 2 Short intake passage At idle a long intake passage is set (torque setting). From 4700 rpm (N62B48TU) the sleeves are pushed back and a short intake passage is thereby set (power setting). When there is no flow, the sliding sleeves remain in their respective position. Varying the intake passages controls the pressure wave in the intake manifold in such a way as to produce a boost effect in the high rpm range. The sliding sleeves are driven by a servomotor assigned to each cylinder bank. The two servomotors together with the differential pressure sensor form a single component. The 12V servomotors are actuated by the DME via a PWM signal. While the sliding sleeves are open (powersetting), the servomotors are actuated with a 5 % PWM signal in order to hold the sleeves in their open position. The servomotors do not have position feedback. The sleeves can be inspected visually through the throttle valve opening. The sleeves are opened and closed once when the ignition is turned on.This prevents the sleeves from seizing during extended operation in the torque setting. The bores for the fuel injectors and the connections for crankcase and tank ventilation are located on the intake system (DISA). The intake system is made of glass-fiber reinforced plastic. 10 E65/66 Model Update Crankshaft The N62B48TU engine has a steel crankshaft. To reduce power loss due to oil churning in the crankcase, the crankpin width has been reduced from 42 mm to 36 mm. Oil Pump The geometry of the oil pump is vehicle specific adapted. Oil churning losses in the crankcase are further reduced by the modified design of the oil deflector. Oil Dipstick The E65 Facelift model series is equipped with an electronic oil level display. The dipstick has a modified handle in black. Inlet and Exhaust Valves The stem diameter has been reduced from 6 mm to 5 mm to reduce moving masses. Spark Plugs The previous surface-gap spark plugs with 2 ground electrodes have been replaced by spark plugs with the spark position brought forward and a hook electrode. This enables better ignition of the fuel/air mixture. In the new spark plugs the center electrode is made of platinum (replacement interval: every 100,000 km). Digital Motor Electronics DME The N62TU engine is equipped with the Digital Motor Electronics (DME) ME9.2.2.The functions of the ME 9.2.2 are the same as forthe previous ME 9.2 of the N62 engine with the following changes: • New processor • Lambda oxygen sensor LSU 4.9 • Hot-film air-mass meter HFM 6 • Software for electronic oil level measurement. 11 E65/66 Model Update Lambda Oxygen Sensor An LSU 4.9 oxygen sensor is used as the control sensorforeach cylinder bank. The LSU 4.9 oxygen sensor reaches operational readiness twice as fast (10 sec.) as the LSU4.2. This rapid starting capability is made possible by the use of a smaller ceramic element. The outer dimensions of the oxygen sensor remain unchanged. The previous opening for the supply of ambient air (reference air measurement) has been dispensed with. The new sensor differs from the LSU 4.2 in that a porous layer perme¬ able by air is used instead of a reference air channel. The function stays the same. The ambient air is directed to the measuring element via the connecting cable. Hot-film Air-mass Meter (HFM) The HFM 6.4 is used in the N62TU engine.The sensor signal is already digitized in the HFM 6.4.The digitized signal is sent to the DME. 12 E65/66 Model Update Transmission The GA6HP26Z automatic transmissions has been optimized for all the model series in the following respects: • New linings on the shift clutches • Use of new fine filters in the hydraulic system • Newly designed converter connection The new designation forthe transmission is GA6HP28Z. The newly designed transmission control unitGS 19.11 is used forthe automatic trans¬ missions. Compared to its predecessor (GS 19.04) it offers the following advantages: • New processor with higher computing capacity and flash memory expanded from 512 KB to 1 MB • Designed to withstand higher temperatures • Electromagnetic compatibility considerably improved • Reserve for further functions • Optimization of shift quality, shifting time and hysteresis tuning. The control unit is located on the mechatronics module in the transmission. The housing and the pin assignments have not been changed. GA6HP28Z 13 E65/66 Model Update Chassis and Suspension There continue to be three different suspension variants as before: Newly tuned stan¬ dard suspension (air suspension standard on the long versions), Sport suspension, Electronic Damper Control Further suspension modifications include: • Widening of the total toe on the rear axle by 14 mm • Redesigned cruise control (ACC II) • 750i has 17" high performance brake on the front axle • New steering wheel design and wheel designs E65 750i E66 750U E65 760i E66 760U Standard w i Styling Number 175 175 149 89 Size 8 x 18” 8 x 18" 9 x20"front 10 x20"rear 9 x 19"front 10 x 19"rear Tire 245/50R18 All-season or All-sea¬ son run-flat (no cost) 245/50R18 All-season or All-sea¬ son run-flat (no cost) 245/40R20 front 275/35R20 rear Performance 245/40R20 front 275/35R20 rear Performance Sport Package pH Styling Number 95 95 Size 9 x 19"front 10 x 19"rear 9 x 19"front 10 x 19"rear Tire 245/45R19 front 2 75/40 R19 rear Performance 245/45R19 front 275/40R19 rear Performance Optional t \jy Styling Number 95 95 91 Size 9 x 19"front 10 x 19"rear 9 x 19"front 10 x 19"rear 8 x 18" Tire 245/45R19 front 2 75/40 R19 rear Performance 245/45R19 front 275/40R19 rear Performance 245/50R18 All-season 14 E65/66 Model Update Exterior Design The current BMW 7 Series has been on the market since Autumn 2001. During this period the E65 - together with the E66 long version - has surpassed even the success¬ ful predecessor model E38 in terms of sales figures. The responsibility for this sales suc¬ cess lies predominantly with the US market. The body has been redesigned all round. The vehicle boasts a new: • Hood • Trunk lid • Front fenders • Front light assembly • Rear light assembly • Kidney grills • Accentuated side skirt • Front bumper cover • Rear Bumper cover • Wheel well covers • Fog Lights Changes to the E65/66 Body 15 E65/66 Model Update Front End At the front end the headlights, the front grill, the bumper trim, the hood and the front fenders have been changed. The light rings around the high-beam headlights are now completely enclosed. Bi-xenon active (AHL controlled) headlights are included as standard. The fog lights are bigger and are accommodated in separate openings. The air intake in the bumper trim is equipped with three grills. The openings are adapted for the brakes, new engine, and ACC II (option). The front grille is now wider (14 chrome plated vertical bars per kidney) and their outer contours run almost parallel to the headlight contours. The front fenders have been modified in the area of the headlights. Due to the new head¬ light shape and the new front grill, the hood has also been redesigned. The hood and fenders are still made of aluminium. The wheel arch trims, bumper trim carriers and bonnet insulation trim have also been redesigned.

The outer contours of the rear lights in the side panels have stayed the same. The rear quarter panels have not been changed. BumperTrim The bumper trim has also been redesigned. The side rubbing strips are slightly shorter and no longer stretch to the wheel well opening. The exhaust tailpipes are covered by the bumpertrim. Trunk Lid The design features of the trunk lid have also been altered. The three-part light surround has been replaced by two larger-sized rear lights which merge almost seamlessly into the rear lights in the quarter panels. Other new features next to the BMW badge with chrome frame are the country-specific numberplate trim and the long chrome strip which visually connects the reversing lights to each other. In addition, the new number plate lights and the new trunk lid lock are inte¬ grated in the trunk lid. The trunk lid trim panel is adapted to the new trunk lid. The bulbs in the rear fog/reversing lights can be easily replaced by unclipping the corresponding trim panels. The trunk lid lock is located to the right of the numberplate light and is not longer directly visible. E65/E66 RearView 18 E65/66 Model Update All three rubbing strips and the impact absorber can be removed from the outside. The points at which the bumper trim is connected to the body have not changed (red arrows on picture below). Structural changes to the front and rear bumper trims have increased the length of the car by 10 mm. Thus the new length is 5039 mm forthe E65 and 5179 mm for the E66. Attachment Parts for Rear BumperTrim Index Explanation 1 Rear bumpertrim 2 Rear right rubbing strip with 3 Cover for bolted towing lug 4 Rear middle rubbing strip with chrome strip and locators for four P DC sensors 5 Impact absorber 6 Rear right rubbing strip with chrome strip 19 E65/66 Model Update Interior Design The interior is now even more appealing and of higher-quality thanks to the use of new materials, colors and surfaces. For example, all the trims and the fresh-air grills which are in the immediate field of vision of the occupants are coated with superior quality paint (titanium instead of dark silver). The headliner trims are coated with structural soft paint in the corresponding headliner color (beige, black or stone-grey). The decorative trims now also come in new, superior-quality wood designs. "American walnut" replaces "black cherry" in the basic equipment specification. The fine wood design light or dark "variegated ash" is available as an option. Many individual parts such as e.g. locking knobs, inside door handles, frames of drinks holders etc. are modeled in pearl-effect chrome. InteriorView of Facelift Vehicle 20 E65/66 Model Update Controller The increase in quality can also be seen from the example of the controller. The controller has a new shape and is made from a new material. It is designed in a so-called mono¬ sandwich with leather insert. The leather insert has a practical as well as a visual benefit for the customer in that it is equally pleasant to touch when hot or cold. The controller trim has a new shiny finish thanks to the titanium paint. Index Explanation 1 Leather insert 2 Controller in pearl-effect chrome 3 Titanium painted controller trim Steering Wheel The design of the steering wheel has also been changed. The airbag impact pad now has slightly curved edges at the top and bottom. The steering wheel comes in the same color as the instrument panel trim. Redesigned Steering Wheel Original Steering Wheel 21 E65/66 Model Update IHKA Controls and Light Switch Center The IHKA controls and the light switch center have been visually enhanced. The rotary knobs are modeled in pearl-effect chrome. The buttons or the button groups and the rotary knobs are set off by an "island type” or "floating” design. The corresponding trims are coated with high-quality paint (titanium). The OFF button and defrost button have changed places. Controls for IHKA Index Explanation 1 Switch OFF button (new position) 2 Left interior air supply controller and defrost button (new position) 22 E65/66 Model Update Vehicle Lighting The following system components are installed for the exterior lighting: • Control units - Light module - Power module - Stepping motor controller - Control unit for bi-xenon headlight • Headlights (with parking lights/low beam/high beam and direction indicators) • Fog lights • Front additional direction indicators • Rear light cluster - Tail light - Brake light - Rearfog light - Reverse light - Direction indicator - Third brake light • Lights operating unit • Steering column switch cluster - Steering column switch, high beam/headlight flasher - Steering column switch, direction indicator lights • Sensors. Control Units Light Module The LM light module contains the complete functions for controlling the exterior lights. Cars with adaptive directional headlights no longer have a separate AHL control unit. The functions of the AHL control unit are integrated in the LM .The housing and the plug coding of the LM are not changed. The LM receives the information from the PT-CAN (yaw rate, road speed and steering angle) for controlling the adaptive directional headlights via its own PT-CAN connection. Power Module The power module provides the power for the light module (special loads/consumers terminal). SMC The stepping motor controller is located on the side on the bi-xenon headlight. The stepped motor controller controls and monitors the movement of the stepping motors ofthe adaptive directional headlight and headlight vertical aim control. 23 E65/66 Model Update Lighting System C ircuit Diagram T 24 E65/66 Model Update Legend forSystem Circuit Diagram Index Explanation Index Explanation 1 Additional direction indicator, left 27 Safety and gateway module SGM 2 Direction indicator, front left 28 Trailer module AHM 3 Stepping motors 29 Power module PM 4 Parking light, left 30 Rain/light sensor RLS 5 High beam shutter, left 31 Comfort Access CA 6 Bi-xenon high beam/low beam headlight, left 32 Ride-height sensor, rear 7 High beam light, left 33 Direction indicator, rear right 8 Front fog light, left 34 Tail light, right 1 9 Stepping motor controller SMC for adaptive directional headlight, left 35 Brake light, right 10 Control unit for bi-xenon high beam headlight, left 36 Rearfog light, right/brake force display, right 11 Front fog light, right 37 Tail light, right 2 12 High beam light, right 38 Reversing light, right 13 Bi-xenon high beam/low beam headlight, right 39 License plate light, right 14 High beam shutter, right 40 Raised brake light 15 Parking light, right 41 Numberplate light, left 16 Stepping motors 42 Reversing light, left 17 Direction indicator, front right 43 Tail light, left 2 18 Stepping motor controller SMC for adaptive directional headlight, right 44 Rearfog light, left/brake force display, left 19 Control unit for bi-xenon headlight, left 45 Brake light, left 20 Additional direction indicator, right 46 Tail light, left 1 21 Dynamic Stability Control DSC 47 Direction indicator, rear left 22 Digital Motor Electronics DM E 48 Hazard warning switch 23 Brake light switch BLS 49 Light module LM 24 Car access system 2 (CAS 2) 50 Light switch 25 Steering column switch, high beam/direction indicator lights 51 Ride-height sensor, front 26 Steering column switch cluster (SZL) 25 E65/66 Model Update Bi-Xenon Control Unit The bi-xenon control unit is mounted on the bi-xenon headlight. It provides the voltage supply and ignition voltage for the bi-xenon lamp. Bi-Xenon Headlights The E65/E66 has new headlights. The headlights have a new contour line and a com¬ pletely new internal design. Front direction indicators are only available in white and the only variant available for the US is bi-xenon with adaptive directional headlight control. The light for the parking light rings is generated by a common bulb and directed via the fibre optics to the parking light rings.

The high pressure nozzle is no longer attached to the headlight but attached to the carrier of the bumpertrim.The nozzle is aligned in such a way that only the lens in the area of the low beam light is cleaned. The shape of the nozzle and its cover cap have been adapted to the new design. Index Explanation 1 High pressure nozzle 2 Retaining screws Front Fog Light The frontfog light has been modified. It is the same as the fog light of the E60 with a new housing and a new trim. The procedure for removing the fog light has changed. It is necessary to remove the front assembly underside protection in order to remove the fog light. Then unclip the fog light trim and release the retaining screw. Finally unclip the fog light towards the rear. Index Explanation 1 Fog light 2 Adjustment screw 3 Retaining screw 4 Fog light trim 28 E65/66 Model Update Tail Lamp Assemblies The rear light cluster of the E65/E66 is split into two parts (formerly three parts). One part is integrated in the side panel of the body while the other part is integrated in the trunk lid. The outer contour and the mounting of the rear lights in the quarter panels have not changed but the internal design has been completely changed. The rear lights in the trunk lid are newly designed. Only white direction indicators and sil¬ ver bulbs for the rear direction indicators are available.

Each of the two tail lights (right or left side of the car) comprises two fibre-optic modules that are each made up of four fibre-optic waveguides. The fourfibre-optic waveguides are arranged one on top of the other and each supplied with light by an LED. Because the four LEDs are connected in series, the entire rear light section must be replaced if one LED fails. The advantage of fibre-optic technology lies in the fact that LEDs have a significantly longer service life and a lower energy requirement than conventional bulbs. The illumina¬ tion of the tail light is considerably more uniform than that of a bulb, which is bright in the middle and grows much darker towards the edges. Another reason for using this technol¬ ogy is that the design simply looks better. Index Explanation 1 Supply points for wave guide Brake Light The left and right brake lights are each generated by 16 LEDs. Unlike the parking light LEDs, the brake LEDs are connected in parallel, i.e. if one LED fails the other LEDs remain operational. The LED module can be replaced. When the brake light is actuated, tail light 1 is also switched on - even if the light was not switched on. The high-mounted brake light remains unchanged. 30 E65/66 Model Update Brake Force Display The rearfog lights are also used forthe brake force displays (two-stage brake lights). The car speed must be >5 km/h forthe brake force displays to be activated. And at least one of the following conditions must also be satisfied: • Braking deceleration >5 m/s2 and/or • Control intervention by the anti-lock braking system. The information on car speed, braking deceleration and control intervention by the anti¬ lock braking system is received by the light module in the form of CAN messages from the DSC. The light module activates the brake force display when the above mentioned conditions are satisfied. The brake force display remains activated until the driver lets off the brake pedal. Rear Side Marker Light The reartail lamp is equipped with two extra LEDs which shine through openings in the side trim directly as a side-marker lamp. These LEDs cannot be replaced. 31 E65/66 Model Update Bus Overview C hanges in the E65/E66 Bus Diagram in 03/2005 Adaptive Directional Headlights and Light Module When adaptive directional headlights were introduced, it was necessary to connect the AHL control unit to the PT-CAN. The AHL control unitwill be removed from the vehicle in 03/2005 because this function is to be taken over by the LM light module. The light module receives the information from the PT-CAN (yaw rate, road speed and steering angle) via a direct PT-CAN connection. MOST The KHI headphones interface KHI and LOGIC7 control units have changed places in the MOST ring. PT-CAN Active Cruise Control II ACC II is used instead of Active Cruise Control ACC. Changes in the E65/E66 Bus Diagram Since 03/2004 There have already been some changes in the bus structure due to the ISIS in 03/2004 K-CAN S The RDC control unit was removed because the tire monitoring function was taken over by the Run Flat Indicator software in the DSC. Dropping of the KHA module (headphones connection) as a control unit on the K-CAN. The jacks of the headphone connections for rear-compartment entertainment are con¬ nected directly to the KHI (headphones interface). MOST Extended to to include the SDARS (Satellite Digital Audio Radio Services) control unit. byteflight The satellites are connected directly to the SGM (Safety and Gateway Module) through integration ofthe SIM in the gateway module. The star structure ofthe byteflight has been retained. The SGM serves as the main gateway for the entire bus system. PT-CAN The PT-CAN has been extended to include the a second DM E control unit. This was deemed necessary when the 12-cylinder engine was introduced in the 760i/il_. 32 E65/66 Model Update E65/66 Bus Topology Chart S o 2 o. v> 3 CD * O to QQ o o- o -*—r O h_ a z < o * m • « • * Z < O o tfl □ CD trt z 1 — z 3 QQ i < to < o o o □ t 1 0 . i 1 33 E65/66 Model Update K-CANP K-CAINS MOST bytefHght PT-CAN E65/E66MU Energy Management The CAS and DME control units are no longer powered by separate outputs on the power module. These control units are combined together with the light module, the instrument cluster and the FBD (remote control receiver) on a common connection. This output is known as Terminal 30 Special loads/consumers (Kl. 30SV).This terminal can be switched by means of a hardware alteration in the power module. i v FBD 34 E65/66 Model Update New Deactivation Strategy In the previous concept of power module deactivation, only the path of terminal 30 loads/consumers (term. 30B and term. 30U) was de-energized in the event of a closed circuit current fault. Only the current at term. 30U and term. 30B was evaluated to detect this fault. What is new is that terminal 30SV can now also be switched. However current measure¬ ment is not possible at terminal 30SV. Increased closed-circuit current consumption is detected indirectly by monitoring bus communication on the K-CAN. If bus communication is present without reason, terminal 30SV is briefly disconnected from the power supply. In this way it is possible to rectify possible problems caused by faulty software because the control units should switch back into sleep mode properly after the restart. The infor¬ mation on a problem however is stored in the power module and the workshop can search for a fault in the affected control units at terminal 30SV. Disconnection of term. 30SV is performed only if term. 30B and term. 30U were already disconnected beforehand or at the same time and if none of the light functions (parking lights, hazard warning system) is switched on. Deactivation strategy in event of excessive closed-circuitcurrent 1. Reset of terminal 30U and terminal 30B in event of violation of the closed-circuit current threshold (as previously) 2. Disconnection of terminal 30U and terminal 30B in event of renewed violation of the closed-circuit current threshold (as previously) 3. Reset of terminal 30SVforl0 seconds (new) if the bus users on the K-CAN (PM, CAS, LM, instrument cluster, DWA) have not gone to sleep within 5 minutes of terminals 30U and 30B being disconnected. The "Term. 30SV reset" procedure is carried out only once within a closed-circuit current monitoring phase as this action causes the entire vehicle electrical system to be cut in (high current consumption). Deactivation strategy in event of too many wake-up operations 1. Disconnection of terminal 30U and terminal 30B if the wake-up counterthreshold is reached, currently 30 wake-up operations 2. Reset of terminal 30SVforl0 seconds (new) if the bus users on the K-CAN (PM, CAS, LM, instrument cluster, DWA) have not gone to sleep within 5 minutes of ter¬ minals 30U and 30B being disconnected. Note: The connected control units are not operational during the period when terminal 30SV is deactivated. The car cannot be unlocked with the remote control during this phase. 35 E65/66 Model Update It is still possible to open the car door with the mechanical key, but this results in an alarm being triggered if a movement in the passenger compartment is detected as the anti¬ theft alarm system is still armed and responds as if for example a window has been bro¬ ken. The anti-theft alarm system is deactivated by inserting the ID sensor in the CAS slot, whereby disarming is signalled to the anti-theft alarm system if the vehicle electrical sys¬ tem is activated. Note: The instrumentclusterretainsthedataon account ofthe brief discon¬ nection (10 seconds). Only the clock is slow by the corresponding time. Normal Sleep Procedure In a "normal" car sleep procedure, the CAN bus goes to sleep a few minutes after "termi¬ nal R OFF". After 16 minutes the PM sends the signal to deactivate the loads/consumers and the bus is woken up briefly in the process. The "VA_Roof" driver is deactivated and the CAN bus goes to sleep again. After 60 minutes have elapsed (codable value if no telephone/EGS logs in as a load/consumer in stationary mode 16 minutes) the "VA_Body" driver is also deactivated, by means of which a current of approx. 200 mA for relay activation forVA_K is likewise omitted. The power module then goes into closed-cir¬ cuit current monitoring mode. Detection of a C losed-Circuit Current Violation During closed-circuit current monitoring the power module measures the voltage value every 5 seconds and the current value every 60 seconds. The power module goes into increased closed-circuit monitoring mode in the event of a closed-circuit current violation (I >80 mA). Here the power module determines the pre¬ sent current value every 1.5 seconds over a waiting period of 8 minutes. During this peri¬ od the vehicle electrical system is given the opportunity to accept a normal closed-circuit current again. If during the 8 minutes a current is detected which is below the closed-circuit current threshold of 80 mA for longer than one minute, the waiting period is started again and the power module goes into closed-circuit current monitoring mode again. If the closed-circuit current violation persists afterthe waiting period has elapsed, the shutdown counter is started (90 seconds). Then a general reset is performed. General reset means that all loads/consumers sup¬ plied by the power module with the exception of terminal 30SV and the anti-theft alarm system are disconnected from the battery for 30 seconds. Then the closed-circuit current is monitored for a further 8 minutes. If the closed-circuit current violation persists, the shutdown counter is started again (90 seconds). Then all the loads/consumers are deactivated (with the exception of terminal 30SV and the anti-theft alarm system). If a further closed-circuit current violation is indirectly determined via bus activity over a time period of 5 minutes, a one-off reset of terminal 30SV is performed for 10 seconds. 36 E65/66 Model Update I [mA] Sleep Procedure Without Closed-C ire uit Current Violation Index Explanation 1 Terminal R "OFF" 2 After 16 minutes the PM sends the signal to deactivate the loads/consumers and the bus is woken up briefly in the process. The "VA_Roof" driver is deactivated and the CAN bus goes to sleep again. 3 After 60 minutes have elapsed (codable value if no telephone fitted 16 minutes) the "VA_Body" driver is also deactivated. The power module then goes into closed-circuit current monitoring mode. 37 E65/66 Model Update Sleep Behavior with Closed-Circuit Current Violation I [mA] Index Explanation 1 Terminal R "OFF" 2 After 16 minutes the P M sends the signal to deactivate the loads/consumers and the bus is woken up briefly in the process. The "VA_Roof M driver is deactivated and the CAN bus goes to sleep again. 3 After 60 minutes have elapsed (codable value if no telephone fitted 16 minutes) the "VA_Body" driver is also deactivated. The power module then goes into closed-circuit current monitoring mode. 4 Closed-circuit current violation with 500 mA. The current violation at the end of the waiting period of 8 minutes persists. 5 Entry in the fault memory with the associated current value. The CAN bus is woken up and the shutdown counter started for 90 seconds. A general reset is performed for 30 seconds when the shutdown counter expires. Simply the KL30SV driver and the power supply for the anti-theft alarm system are not disconnected. 6 The current violation at the end of the second waiting period of 8 minutes persists. The CAN bus is woken up again and the shutdown counter started again for 90 seconds. 7 Terminal 30U, terminal 30B and all other drivers are disconnected from the battery when the shutdown counter expires. Sole exception: KL30SV and the power supply for the anti-theft alarm system are not disconnected. 8 One or more control units (LM, IKE, CAS, DM E) is/are active for longerthan 5 minutes. 9 Reset of KL30S V for 10 seconds (if no light function is active). 10 Reset of KL30S V for 10 seconds (if no light function is active). 38 E65/66 Model Update Measures for Maintaining Battery Starting Capability (SoC) Electric Loads/Consumers in Stationary Mode Certain loads/consumers may be active even when closed-circuit current monitoring of the power module is already running. This is necessary for various reasons: • Legally required electric loads, e.g. parking lights, hazard warning system • Convenience for the customer, e.g. radio function, telephone These loads/consumers must be excluded from the closed-circuit monitoring system in orderto avoid misinterpretation in the power module. Forthis purpose, these loads/con¬ sumers must log in with the power module. In turn, the power module recognizes the activity and accepts the higher power consumption. When these systems are deactivat¬ ed, the corresponding control units log off from the power module. Disconnection of Terminal 30 In the previous concept of power module deactivation, terminal 30 (term. 30U and term. 30B) was not disconnected in the case of a car without a closed-circuit current violation. A slow drop in the capacity of the car battery (SoC = state of charge) below the starting capability limit without a discernible reason was possible and this effect was counteracted by no action of the power module. The following function is new: When loads/consumers are logged off, a codable waiting time (currently 5 minutes) ensues from the point "terminal R OFF". Term. 30U and term. 30B are disconnected from the battery when the state of charge drops below the starting capability limit. This disconnection is not preceded by a "general reset". SoC ^ Index Explanation 1 Starting capability limit 2 Terminal R "OFF” 3 Disconnection of terminal 30U and 30B 39 E65/66 Model Update Shortening of Run-OnTime Before Facelift (3/2005) - The power module deactivation in a car with a closed-circuit current fault, a further battery disconnection on account of a closed-circuit current viola¬ tion takes place only after a run-on time of 60 minutes (16 minutes). As a result of this long run-on time the state of battery charge could drop far below the value of the starting capability limit without an intervention by the power module. SoC As of 3/2005 - The improvement of the new deactivation strategy becomes apparent with a renewed activation of the loads/consumers (by a terminal change or unlocking of the car) in the event of a previously ascertained closed circuit current violation or an extended starting capability limit which has already been reached. In this case, closed-circuit current monitoring already begins after 2 minutes (normally 60 minutes). Together with the fixed waiting period of 8 minutes, it would therefore take a maximum of 10 minutes until the shutdown counter is started. The shortened run-on time is reset again as soon as the power module has registered an "engine running" status once.

They are: • ASK • CD changer Audio System Controller (ASK) In addition to the new trim shape and paint finish, the audio system controller now has two extra buttons: • AM/FM button for directly switching the radio to and between AM/FM reception • MODE button for changing next audio source. Audio System Controller Index Explanation 1 Rotary push button for switching on/off and volume control of audio system 2 CD drive slide-in compartment 3 Eject button 4 Search button 5 AM/FM button 6 MODE button 45 E65/66 Model Update CD Changer The CD changer available for the E65/66 facelift (Option 672) now supports the playback of CDs with MP3 and WMA files.The MP3/WMA files are decoded in the CD changer. What is MP3? • Stands for M PEG Layer 3 (MPEG = Moving Pictures Expert Group) • Is a music compression method. It is based on the formats originally designed for digital sound or picture transmission (MPEG 1 or 2) • It requires 8 to 12 times less storage space for virtual CD quality. Approximately 10 audio CDs in compressed form can be stored on a standard 640 MB data CD. • It was developed by the German Fraunhofer Institute for integrated circuits (Fraunhofer IIS Audio). What is WMA? • Like M P3, Windows Media Audio (WMA) is a compression method for audio data that produces a sound with more detail than M P3 at low bit rates (up to approxi¬ mately!^ kbit/s). Operation, Display, and Playback The CD changer is operated by means of the controller. Information such as folder name, music track, or artist are shown in the central display. Detailed information based on ID3 tags can also be represented. ID3 tags contain additional information that is added to the music data. If a basic audio system is installed, the decoded data of the CD is sent as digital signals via the MOST to the ASK. Here they are converted to analogue data and output via the amplifier and the speakers. If a 'Top-HiFi' system (Logic7) is installed, the decoded audio data are transmitted in digi¬ tal form via the MOST from the CD changer directly to the Top-H iF i amplifier, from where it is output. The CDs are played back even when the CD changer is simultaneously holding CDs with M P3 files, WMA files, and "normal" audio data. <• S ■ ; : m sCA FM AM CD ^ CDC TV DVD Display of ID Tags — i h N FIND U CO 06 > BMW Z4 Musk Journey > St Germain 01 Qt J28 \ + a w» ■ Pr ival ■flleH 1-I2B kbps mp3-cbr Dusty Springfield BMW Z4 Musk Journey CD06-03 lUMJEHM 11 HDD AM 46 E65/66 Model Update
