Introduction to BMW

BMW Model Identification

BMW uses two different methods of identifying its products:

• External Designations are for customers to identify BMW products. These are
marketing designations commonly referred to as trunk badges.

• Internal Designations are used by BMW and center personnel to identify a particular
production version.

External Designations

External designations located on the
trunk or tailgate are the model names.

Customers and the public identify
BMW products by these names.

The trunk badges consist of a combination of numbers and letters. The badge shown is
typical of 3, 5, and 7 series vehicles. The first digit represents the series identification.
The last two digits mark the engine displacement. The i represents the type of fuel deliv¬
ery (injected).

The external designations are created by the sales and marketing department to position
each model in a certain target segment of the vehicle sales market.

Occasionally there are examples where the actual engine displacement does not match
the designation. This is a marketing decision to continue familiar name recognition from
one version to the next and to create a spacing between models. Examples are:

• 1996-2001 740i -4.4 liter

• All 323i - 2.5 liter

• 2005 750i/Li - 4.8 liter

There is another series of badges that begin with a letter followed by a single digit.
These are found on:

• Roadsters (E36/7, E52, E85)

• SAV (E53, E83)

• Motorsport

Additional letters sometime follow the badge numbers and are used to further identify
each model. Examples include:

• C or c - Coupe or Cabrio • i - Fuel Injected • s - sport

• L - long wheel base • M - Motorsport • e - etta

• x - all-wheel drive • t - touring/sports wagon • d - Diesel

Introduction to BMW

Internal Designations

Internal designations are created and used by the Engineering and Technical Develop¬
ment departments to identify a new model during the design of the car. The use of the
internal designations carries over to the Technical Support groups after production.

Internal designations refer to the entire vehicle series of a particular body design. For
example, the E46 designation describes all 3 series cars of that design. BMW products
start with an “E” and are followed by a two digit number. Not all design concepts make
production, so internal designations are usually not sequential. Table 1.1 lists the internal
designations, series number and the years produced.

The E designations can include an additional number separated by a slash (/) to indicate
a different model within a particular chassis group. Example:

• E36/7-Z3 • E46/3-Sport Wagon • E46/16-All-Wheel Drive

• E36/5- 318ti • E46/2-Coupe

VIN Location on Vehicle

The VIN is located on the vehicle in the following locations:

• Left lower corner of the instrument panel. This is viewed through the windshield
from outside the vehicle.

• B pillar compliance label. On the drivers side doorjamb.

Additionally the VIN is stamped into the chassis in one of two locations:

• Under the hood on right side of engine compartment bulkhead.

• Under the hood on right side shock tower.

The production date of the vehicle is included in the B pillar compliance label.

Production date information is required quite often when a repair procedure affects only
a certain range of vehicles. The range is based on production dates.

The date shown on the label reflects the actual month and year the vehicle was pro¬
duced. It is not a model year indicator.

Introduction to BMW

Vehicle Production Anti-Theft Labels

Since 1987, the National Highway Traffic Safety Administration (NHTSA) requires that the
VIN be marked on specific parts of the car during manufacture for theft identification. Some
models are exempt if the total number of vehicles imported is below a certain number.

If equipped, label it is also a reference point for the VIN. The label is placed on the follow¬
ing locations:

Engine

Hood

Front bumper
Front Fenders
Quarter panels.
Firewall

Transmission

Trunk li

Rear Bumper
Doors

Shock Tower

Paint Code Identification

When ordering painted parts it is necessary to obtain the vehicle’s paint code. The paint
code consists of a three digit number printed on the color identification tag as shown
below. All color identification tags are located in the engine compartment.

Engine Identification

BMW engines are identified by a combined alpha-numeric code. Like the internal model
designation it is a code used by the Engineering and Technical development teams dur¬
ing the design stages of the engine:

• M - for standard production engines

• S - for Motorsport engines (Motorsport is a separate division of BMW)

• N -for New Generation engines

• P - for Prototype engines

After the letter there are two digits that identify the engine. The table below lists engines
by number of cylinders. Please refer to the BMW Technical Information Card for individ¬
ual model application.

Transmission Identification

BMW uses three different transmission suppliers.

1. Zahnradfabrik Friedrichshafen: A German supplier of BMW transmissions.
Commonly referred to as ZF. ZF manufactures both manual and automatic trans¬
missions.

2. Getrag: A German supplier of BMW manual transmissions.

3. Hydramatic: A French supplier of BMW automatic transmissions. Hydramatic is a
manufacturing division of General Motors Powertrain.

BMW has developed an internal numbering system for their transmissions for parts
ordering, information research, and identification. Each manufacturer uses their own
internal identification system.

The breakdown of the BMW transmission identification code is as follows:

BMW Identification Code Breakdown

A 5 S 440 Z

Digit 1 is the transmission type: -

A = Automatic
S = Standard (manual)

Digit 2 is the number of gears: -1

Digit 3 is a reference for the final drive ratio: -

S = Top gear overdrive
D = Top gear direct drive

Digits 4-6 are a torque rating index: -

Digit 7 identifies the manufacturer: -<-

Z = ZF

R = Hydramatic
G - Getrag

ZF Identification Code Breakdown

BMW Abbreviations and Acronyms

Throughout your career as a BMW Group Service Technician you will come across many
acronyms in the various Technical publications. Even BMW is an acronym. An acronym
is a word formed from the initial letters of a longer word. In the next two pages there is a
list of acronyms describing various systems on BMW Group automobiles and SAVs.

Remember this is only a partial list. The BMW Group is a dynamic company and is
always adding new systems to its products. Look for new systems and acronyms with
new Technical Training courses, Service Information, and Technical Information Bulletins.
