002 Vehicie identification and
VlN Decoder
Vehicle identification Number (VIN), decoding
Some of the information in this manual applies only to cars of a parlicuiar model year or range
of vears. For
examole. 1999 refers to the 1999 model vear but does not necessarilv malch the
caiendsr year in which the car was manufactured or sold. To be sure of the model year of a
particular car,
checic the Vehicle ldentification Number (VIN) on the car.
The VIN is a unique sequence of 17 characters assigned by BMW lo identify each individual
car. When decoded, the VIN tells the country and year of manufacture; make, model and serial
number: assembly
plant and some equipment specifications.
The BMW VIN is on a plate mounted on top of the dashboard, on the driver's side where the
number can be seen through the windshield, The 10th character is the model year code. The
letters
I. 0, Q and U are not used for model year designation. Examples: X for 1999, Y for 2000,
1 for 2001,2 for 2002, etc. The table below explains some of the codes in the VIN for 1997
through 2002 BMW

/Suspension, Steering and Brakes - General
The steering system features variable power assist provided
by an engine-driven hydraulic pump.
Rack and pinion steering
6-cylinder models
(525i, 5281, 5300
Two types of steering systems are used in E39 models. 6-
cylinder (525i, 5281, 530i) models are equipped with a steer-
ing rack system. V-8
(540i) models are equipped with a re-
circulating ball and nut steering gearbox.
Rack-and-pinion steering
Steering components in 6-cylinder models consist of a rack-
and-pinion type steering gear and connecting linltage to the
road wheels.
The steering linkage connects the rack-and-pinion unit
through tie rods to the steering knucltles. The tie rod ends al-
low the wheels to pivot and react to suspension travel.
Recirculating ball and nut steering
V-8 models
(540i)
I
Recirculating ball and nut steering
Recirculating ball and nut steering in V-8 models consists of a
steering box with integrated hydraulic control valve and con-
necting linkage to the road wheels.
Thesteering linkageconnects the steering gearbox through a
pitman arm to the wheels. An idler arm maintains correct toe
angle. The tie rod allow the wheels to pivot and react to sus-
pension travel.
E39 cars are equipped with power disc brakes with integral
antilock brakes (ABS). The parking bralte is a dual-drum sys-
tem integrated with the rear brake rotors.
Power assist is provided by a vacuum booster when the en-
gine is running. The brake pedal
pushrod is connected direct-
ly to the master cylinder, so failure of the vacuum booster
does not normally result in total
bralte failure.
Each disc bralte uses a caliper with a single hydraulic cylin-
der. Brake pads in the left front and right rear contain wear
sensors. When brake pads need replacement, the sensors il-
luminate a light on the dashboard.

Body-General
Seats
4 Anatomically correct seats are constructed from polyure-
10 way seat adjustment thane foam
containing areas or "zones" of different firmness.
They offer good lateral support without constricting the occu-
pant.
The seats have a passive internal ventilation system: Cylin-
drical cavities within the cushions and backrests generate a
pumping effect as the ride motions cause occupant motion.
This
helps remove moisture and feeds fresh air into the seats.
Other features of the seating system:
The seat bases have steel springs for added support and
strength.
The seat control switches are along the outside edge of
the
seat.
Heated seats are an option in all models
In cars equipped with seat position memory, three different
seat confiaurations can be memorized by the seat control
module(s): Seat memory coordinates with outside mirror
memory. These functions are controlled by the seat mem-
ory
module(s).
* For security reasons, the release lever to fold the rear seat
backrest forward is installed in the trunk.
Sport Wagon models: Rear seat
baclts are split 60140, with
the center armrest on the left seat back.
The center armrest incorporates a non adjustable head-
rest. When folded down, the armrest opens out with
cup-
holders and a storage compartment. See 520 Seats for
more details.
instruments and controls
Everything in the interior passengercompartment essential to
the driver is logically grouped and easy to reach. All instru-
ments and controls have been arranged ergonomically and
are fully integrated into the overall design of the vehicle.
Tilt-telescopic steering wheel has
30 mm (1.2 in) of vertical
and longitudinal adjustment.
Multifunction steering wheel contains two
ltey pads con-
taining controls for the sound system, telephone and
cruise control.
Padded dashboard houses the instrument cluster and the
ventilation and heating system.

Central Locking and Anii-Theft
- If the starter engages, the following EWS inputs are function-
ing normally:
Ignition key
Code function
Transmission range switch or clutch position switch
Engine speed sensor
NO JE -
If a vehicle key is lost or stolen, the electronic authorization
for that key
can be cancelled using the BMW scan and di-
agnostic tools
DISplus, GTl or MoDiC.
Force applied to a ley can damage the electronic circuitry
in the key A damaged ley will not start the engine. In that
case, a new key should be purchased and initialized
by an
authorized BMW dealer.

OED-2
On-Board Diagnostics
Specialized OED II scan tool equipment is needed to access
the fault memory and
OED I1 data.
The extra hardware needed to operate the OED
I1 system
consists mainly of the following:
* Additional oxygen sensors downstream of the catalytic
converters.
Fuel tank pressure sensor and device to pressurize
fuel
storage system.
Several engine and performance monitoring devices
Standardized 16-pin
OED II connector under the
dashboard.
Upgraded components for the federally required reliability
mandate.
Malfunction indicator light (MIL)
OED II software illuminates the malfunction indicator light
(MIL) when emission levels exceed 1.5 times Federal
standards.
4 For E34 cars covered by this manual, three different MIL
symbols were used, depending on year and model.
MIL illuminates under the following conditions:
Engine management system fault detected for
two
consecutive OED iI drive cycles. See Drive cycle in this
repair group.
- Catalyst damaging fault detected.
Component malfunction causes emissions to exceed 1.5
times OED
II standards.
Manufacturer-defined specifications exceeded. Implausible input signal.

OED
II fault memory (including the MIL) can only be reset
using a special scan tool. Removing the connector from the
ECM or disconnecting the battery does not erase the fault
memory.
