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 1, 3, 5, 6 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
delivery (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:
E71 X6 xDrive50i - 4.4liter
E9x 335i - 3.0 liter
F01/F02 750i/Li - 4.4 liter
There is another series of badges that begin with a letter followed by a single digit.
These are found on:
Roadsters (E52, E85, E89)
SAV (E53, E70, E83)
SAC (E71, E72)
Motorsport
Additional letters sometime follow the badge numbers and are used to further identify
each model. Examples include:

xDrive - all-wheel drive

X - all-wheel drive
sDrive -sport/standard drive
s - sport
L - long wheel base

i - Fuel Injected
M - Motorsport
ActiveHybrid
GT - Gran Turismo

d - Diesel
e - eta
t - touring/sports wagon
C or c - Coupe or Cabrio

Introduction to BMW

Examples of these badges are:

Internal Designations
Internal designations are created and used by the Engineering and Technical Development 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 E90 designation describes all 3 series cars of that design. BMW products
start with an E (as of 2009 we started using the letter F on some of our vehicles) and
are followed by a two digit number. Not all design concepts make production, so internal
designations are usually not sequential. The table on the next page 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

E36/5- 318ti

E46/2- Coupe

Vehicle Identification Numbers

Vehicle Identification Numbers are referred to as the VIN. BMW utilizes a VIN with a 17
character structure. The characters are grouped to include important vehicle information.
Please take a look at the following simplified explanation:

WBA BR33 4 4 Y E A82019

Digit 1-3 are the manufacturers code:
WBA = BMW AG, Munich. Germany
WBS = BMW M GmbH, Munich. Germany
4US = BMW Manufact. Corp. Spartanburg, SC. USA
5UX = BMW Manufact. Corp. Spartanburg, SC. USA
5UM = BMW Manufact. Corp. Spartanburg, SC. USA
Digits 4-7 are the model code:
Digit 8 is the restraint system identifier:
0 = Seat belts
1 = Seat belts and Driver airbag
2 = Seat belts and Dual airbags
3 = Seat belts, Second generation dual front airbags
4 = Seat belts, Dual-stage advanced front airbags
5 = Seat belts and Airbags (the number and type of
airbags is vehicle dependent)
Digit 9 is a check digit determined by VIN:
Digit 10 is the model year identifier (started in 1980):
A = 1980 model year, sequentially progresses every year. The letters
I, O, Q, U and Z are not used because they can be mistaken for numbers.
A=1980
B=1981
C=1982
D=1983
E=1984
F=1985

G=1986
H=1987
J=1988
K=1989
L=1990
M=1991

N=1992
P=1993
R=1994
S=1995
T=1996
V=1997

W=1998
X=1999
Y=2000
1=2001
2=2002
3=2003

Digit 11 is the Plant code:

A, F, K
= (Plant 1.1) Munich
C, B, D, G = (Plant 2.4) Dingolfing
E, J, P
= (Plant 6.1) Regensburg
L, M
= (Plant 10) Spartanburg
N
= (Plant 9) Rosslyn
W
= (Plant) Graz
V
= (Plant) Leipzig

4=2004
5=2005

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 door jamb.
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.

Vehicle Production Dates

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 produced. It is not a model year indicator.
34
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, the label is also a reference point for the VIN. The label is placed on the following locations:
Engine

Transmission

Hood

Trunk lid

Front bumper

Rear Bumper

Front Fenders

Doors

Quarter panels.

Shock Tower

Firewall

*Please reference S.I.B 00 21 86 (1267) dated June 1990 for more information on
Anti-theft labels.

When ordering painted parts it is necessary to obtain the vehicles 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 during the design stages of the engine:

Engine Numbering System

In order to organize and classify the engines developed by BMW, a numbering system
has been developed.

N 5 5 B 30 M 0
Digit 1 is the engine developer and/or generation:
A = Motorcycle
M = BMW Group (Old Generation)
N = BMW Group (New Generation)
G H K L T = BMW Group (Future Generation)
P = BMW Motorsport
S = BMW M GmbH
Digit 2 is the engine type:
Combustion Engines
4 = in-line 4
5 = in-line 6
6 = V8
7 = V12
8 = V10

Electric Motors
A = Asynchronous
P = Permanent Magnet
R = Switched Reluctance
S = Synchronous
T = Transversal flow

Digit 3 is the engine technology:

Digit 4 is working procedure and/or fuel:
B = Gasoline
D = Diesel
E = Electric
G = Natural Gas
H = Hydrogen
M = Methanol
X = Electronic - Diesel
Y = Electronic - Gasoline
Digits 5&6 are the displacement value:
Digit 7 is the performance class:
S = Super performance
T = Top performance class
O = Upper performance class (standard)
M = Intermediate performance class
U = Lower one performance class
K = Smallest one performance class
Digit 8 is release relevant information:
0 = New Development
1-9 = Revision (such as technical update or cost project)
38
Introduction to BMW

Engine Displacement Identification

ENGINE CODE

In technical literature usually only the group of 3 digits

that follow the basic engine code is utilized for engine
identification. These digits identify the required fuel
type of the engine and its displacement.

M54-B30

30 = 3.0 LITER
DISPLACEMENT

B = BENZINE, GERMAN
FOR GASOLINE

Engine displacement can always be determined by the engine specification plate.

This plate is stamped onto the engines in various locations. There is a lot of information
included in this identification plate. The breakdown of the information on this plate is as
follows:
Powerplant Identification Code
Engine Number
Part Number
powerplant Identification Number

30 8 S 1 11 A
Digits 1-2 are the displacement value of the engine:
30 = 3.0 Liter
Digit 3 is the number of cylinders:
8 = 8 Cylinders
Digit 4 is the engine concept:
D = Diesel (naturally aspirated and direct injection)
E = Fuel injection
K = Catalytic Converter (M10, M20, and M30 engines only)
S = 4-valve technology
T = Turbo (gasoline and diesel versions)
V = Carburetor
Digit 5 is a differentiation index:
Digits 6-7 are the variant numbers:
Digit 8 is the identification for the engine:
A = Remanufactured engine
N = New engine

39
Introduction to BMW

In recent time the Powerplant Identification Code changed from 8 digit to 7 digit. This
mark is located on the crankcase to ensure unambiguous identification and classification.
This engine identification is also necessary for approval by government authorities.
Decisive here are the first seven positions. The first 6 positions are the same as the
engine designation.

Item

Meaning

Index / explanation
M, N = BMW Group
P = BMW Motorsport
S = BMW M GmbH
W = non-BMW engines

Engine developer

Engine type

Change to the basic engine concept

Working method or fuel type and

possibly installation position

B = petrol, longitudinal installation

D = diesel, longitudinal installation
H = hydrogen

Displacement in liters

1 = 1 liter (whole number of liters)

Displacement in 1/10 liter

Type test concerns (changes that

require a new type test)

40
Introduction to BMW

5 = R6 (e.g. N55)
6 = V8 (e.g. N63)
7 = V12 (e.g. N73)
8 = V10 (e.g. S85)
0 = basic engine
1 9 = changes, e.g. combustion process

8 = 0.8 liter (tenth of liter)

A = Standard
B Z = Depending on requirement, e.g. RON 87

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 transmissions.
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:
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

5 Hp 24
Digit 1 is the number of gears:
Digits 2-3 refer to the type of transmission:
HP = Hydraulic planetary
Digits 4-5 are an internal ZF designation:

43
Introduction to BMW

Automatic Transmissions
In technical documentation, the transmission designation is used to ensure the unambiguous identification of the transmission. Frequently, however, only an abbreviation is
used. This short form is used to assign a transmission to a transmission family. For example, we often talk about the GA8HP transmission family, which consists of several transmissions such as the GA8HP45Z, the GA8HP70Z and the GA8HP90Z.

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.
