Rear Suspension
ELECTRONIC HEIGHT CONTROL
(EHC) COMPONENT REPLACEMENT
Sport Premium rear suspension is an option on Sport Wagon
models and standard on
1999 and later V-8 Sport Wagons.
This suspension incorporates electronic height control
(EHC)
using air springs.
With vehicle lifted off the ground,
if the rear air springs can be
compressed by hand, either the spring is defective or the sys-
tem is depressurized.
Locate
EHC faults using BMW scan tools DIS or MoDiC. EHC
description and some troubleshooting is covered in 300 Sus-
pension, Steering and Brakes-General.
Air spring replacement is covered earlier in this chapter. See
Air spring, removing and installing.
CAUTION-
Maintain high levels of cleanliness around air line connec-
tions when disassembling and assembling air suspension
components. Even
small dirt particles can cause leakage in
the pressurized system.

(EHC) components
1. Air spring
2. 1 liter air reservoir

I Bodv-General
Bumpers
The front and rear bumpers are clad in high quality
deform-
able plastic and, at solid barrier impact speeds of 4 kph (2.5
mph), provide protection with virtually no damage to the
bumper
orthe vehicle. In addition to hydraulic dampeners.
which absorb the initial impact energy, these bumpers are
backed by compressible tubes. These deform in a controlled
manner at impact speeds greaterthan that
forwhich bumpers
and hydraulic dampeners are designed. This helps avoid ex-
pensive damage to the body at impact speeds up to 14 kph (9
mph).
The E39 Sport Wagon was introduced to the US market in
911 998 (model year 1999). It shares many components with
the E39 sedan and is identical to it from the B-pillar forward.
US
marltet 5 Series Sport Wagons are available in two vari-
ants:
6-cylinder
(5251, 528i) powered by the 2.8 liter M52 TU en-
gine (1 999) or the 2.5 liter M54 engine (2000 and later)
* V-8 (540i) powered by the 4.4 liter M62 TU engine
The wheelbase of the Sport Wagon is the same as the sedan.
Howeverthe body is 30
mm (1.2 in) longer and 10 mm (0.4 in)
higher.
The Sport Wagon rear suspension was redesigned to elimi-
nates the upper rear spring strut mounting on the E39 sedan.
The use of separate coil springs and
shoclc absorbers results
in a flat, wide floor in the cargo area. See
300 Suspension,
Steering and Brakes-General.
The self-leveling air spring suspension system (electronic
height control or EHC) is standard on Sport Wagon V-8 mod-
els and optional on 6-cylinder models.

Airbags
Front airbags, s~de a~rbags, pyrotechnic seat belt tensioners
and the Battery Safety Terminal (BST) are integrated into the
Supplemental Restraint System (SRS) and its variants.
NOTE-
The BMW SRS system is called Multiple Restra~nt System
(MRS). Over the years,
E39 cars were equipped with MRS,
MRS
11, MRS 111. Each version offers varied features and im-
provements over the previous system.
< As many as 8 airbags may be installed in E39 cars, depend-
ing on model and MRS version.
The front
airbags operate without sodium azide propellant,
widely considered an irritant when an
airbag is deployed.
Starting with
1999 models. "smart"front passenger and driver
airbags were installed. These are of the dual-threshold, dual
stage design, including a
sensorto help prevent the unneces-
sary deployment of the passenger side
airbag if the seat is un-
occupied.
MRS control Depend~ng on options chosen, one airbag may be installed in module each door of the sedan and Sport Wagon models, protecting
passengers against
s~de impacts.
Head Protection System (ITS)
airbags strelch diagonally
across the tops of the front doors.
Airbag deployment automatically triggers fuel shutoff, turns
on the hazard and interior lights, and unlocks the doors.
- -
WARNING -
Airbags are inflated by an explosive device. Handled im-
properly or without adequate safeguards,
airbag units can
be very dangerous. Special precautions must be observed
prior to any worlc at or near any of the airbags. See
721 Air-
bag System (SRS).
Always disconnect the battery and cover the negative
(-) battery terminal with an insulator before starting di-
agnostic, troubleshooting or service work on cars fitted
with SRS, and before doing any welding on the
car.

Battery safety terminal
(BST)
4 Starting with 1999 models (9198 production and later), a py-
rotechnic (explosive charge) device automatically discon-
nects the battery positive terminal during impacts. Key
features,
like power windows and door locks, remain opera-
tional.
Security
Electronic immobilization (EWS)
Ignition key transponder signal All
E39 vehicles incorporate an electronic immobilization sys-
tem known as EWS. This svstem uses a wireless comrnuni-
cation link between a transponder chip in the ignition key and
the ring antenna surrounding the ignition switch. The EWS
control module blocks the starting of the vehicle unless the
correct coded ignition key is used.
NOTE-
Electronic immobilization is sometimes referred to as the
driveaway protection system.
Antitheft alarm (DWA)
This is adealer-installed option for which the E39 vehicles are
factory-wired. When armed, the system monitors door
loci(
contacts and trunk and engine hood locks and sounds a siren
if it detects tampering.
E39 interiors have a unique character, with a combination
of
sporty features and innovativedesign. All body versions were
made in a wide choice of interior and exterior colors. New col-
ors with matching leather or leatherette upholstery were intro-
duced for each model year.
Driving
comfort is enhanced by power steering, tilt steering
wheel, height-adjustable front seats, and electrically adjust-
able and heated rear-view mirrors. Inside the car there are
reading lights at four seating positions.

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.
