Information you need to know
Model
When ordering parts it is important that you know the correct
model designation for your car. Models covered in this E39
manual are the
525i,5281,530i, 540i in Sedan and Station
Wagon body styles.
Model year
This is not necessarily the same as date of manufacture or
date of sale.
A 1999 model may have been manufactured in
late 1998, and perhaps not sold until early 2000. It is still a
1999 model. Model years covered by this manual are 1997 to
2002.
Date of manufacture
This information is necessary when ordering replacement
parts or determining if any of the warranty recalls are applica-
ble to your car. The label on the driver's door below the door
latch will specify the month and year that the car was built.
Vehicle
Identification Number (VIN)
This is a combination of letters and numbers that identify the
particular car. The VIN appears on the state registration doc-
ument, and on the car itself. One location is on the right front
strut tower in the engine compartment (arrow), another in the
lower left corner of the windshield.
Engine code
5 Series car covered in this manual are powered by
6 and 8 - cylinderengines. For information on engine codes and en- -. -
gine applications, see 100 Engine-General. -
Transmission code
The transmission type with its identifying code may be
impor- :
tant when buying clutch parts, seals, gaskets, and other .- transmission-related parts. For information on transmission
codes and applications, see 200 Transmission-General.

Maintenance
Suspension, front, inspecting
Inspection of the front suspension and steering includes a
check of all moving parts
forwear and excessive play. Inspect
ball joint and tie-rod rubber seals and boots for cracks
ortears
that could allow the entry of dirt, water, and other
contaminants. See
310 Front Suspension.
Suspension, rear, inspecting
Differential and rear drive axle service consists of checking
and changing the gear oil, inspecting for leaks, and checking
the drive axle
CV joint boots for damage.
The areas where
lealts are most likely to occurare around the
drive shaft and drive axle mounting flanges. For more infor-
mation on identifying oil leaks and theircauses, see
330 Rear
Suspension and
331 Final Drive.
Tires, checking inflation pressure
Correct tire pressures are important to handling and stability,
fuel economy, and tire wear. Tire pressures change with tem-
perature. Pressures should be
checked oRen during season-
al temperature changes. Correct inflation pressures can be
found on the driver's door pillar and in the owner's manual.
Note that tire pressures should be higher when the car is
more heavily loaded.
WARNING-
Do not inflate any tire to a pressure higher than the tire's max-
imum inflation pressure listedon the sidewall. Use care when
adding air to warm tires. Warm tire pressures can increase as
much as
4 psi (0.3 bar) over their coldpressures.
Tires, rotating
BMW does not recommend tire rotation. Due to the car's sus-
pension design, the front tires begin to wear first at the outer
shoulder and the reartires begin to wearfirst at the middle of
the tread or inner shoulder. Rotating the tires may adversely
affect road handling and tire grip.
Transmission service, automatic
The automatic transmissions installed in E39 models are
filled with special automatic transmission fluid. The transmis-
sion lubricant type can be found on the "type-plate" on the
side of the transmission. The recommended lubricants are
listed earlier in this repair group. See Fluids and lubricants.
If in doubt, consult an authorized BMW dealer for alternate

perform a closed-circuit current measurement as the first test.
For diagnostic purposes, it is important to not disconnect the
battery. Disconnecting the battery may reset a faulty control
unit, preventing proper diagnosis.
The following test is generally completed overnight using a
multimeterwith a closed circuitcurrent measurement adaptor
with a recording function
- Check that battery voltage is 12 volts or higher. If lower,
recharge battery.
- Switch off electrical consumers (interior lights, telephone,
aftermarket equipment, or others).
- Open luggage compartment and remove battery trim panel.
Use screwdriver to lock latch on trunk lid or hatch, simulating
closed luggage compartment. Close other doors.
- Open driver's door, then close it, simulating driver entering
vehicle.
- Switch ignition to RUN position for at least five seconds, then
turn ignition to OFF position. This simulates driving vehicle.
- Open and close driver's door, simulating driver leaving
vehicle.

Body-General
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.

Instrument cluster
Instrument cluster uses large easy-to-read analog instru-
ments and is removable as a unit without removing the dash-
board. On-board computer and Check Control functions are
integrated into the instrument cluster displays.
Service Interval Display
Service Interval Display calculates vehicle service needs
based on current driving patterns, and indicates to the driver
when the car requires
service
On-board navigation
An integrated on-board navigation system, based on Global
Positioning System (GPS) technology, is optionally available
on
E39 cars. When installed, a multifunction monitor is includ-
ed in the center of the dash above the radio. in addition to dis-
playing navigation system information, this monitor accesses
On-Board Computerfunctions, audiosystem controls, mobile
phone dialling and memory, and automatic ventilation.
Park Distance Control (PDC)
Park Distance Control (PDC) is an optional system which
uses ultrasonic sensors in the rear bumper trim to warn the
driver of approaching too close to obstacles when parlting.
Central body electronics
E39 vehicles are equipped with an integrated complex of
electronic modules connected mostly via K-Bus. This system,
called central body electronics (ZKE
Ill), is primarily con-
trolled by the general module (GM
Ill). An overview of ZKE Ill
functions is found in 600 Electrical System-General. Details
of ZKE
Ill functioning is in the following repair groups:

I Door Windows 1
This repair group covers door glass, window regulator and
power window motor repair information.
CA U JIO&
All E39 models are equipped with side-impact airbags in the
front doors. Some models are also equipped with
airbags in
the rear doors. Be sure to read the
airbag warnings and cau-
tions in 721
Airbag System (SRS).
Electric window switch replacement is covered in 612
Switches.
The windshield, rear window, fixed rear doorglass, and cargo
compartment glass (Sport Wagon only) are bonded using
special adhesives and tools. It is recommended that bonded
glass replacement be done by an authorized
BMW service fa-
cility or an automotive glass installer.
Special tools
Some window repair operations require special tools.
Power windows
- Power window features in E39 models include:
Control of the front and rear door window motors is carried
out directly by the General Module (GM
Ill).
One-touch operation in both directions on all four windows.
Cable type window regulator used for all door windows.
. Anti-trap protection provided by pressure sensitive finger
guard.
Right front and each rear door has a single window switch
located in door handle trim.
Rear door window switches can be deactivated by press-
ing child lock-out switch in the driver's window switch block.
Convenience closinglopening of the windows from driver's
loci( cylinder or convenience opening only from remote un-
lociting feature (FZV) remote key.
Window (FZV) operation can be owner customized with
Car Memory function. See 515 Central Locking and Anti-
Theft.
After ignition is switched off, electric windows can be oper-
ated until a door is opened or until
I6 minutes has elapsed.
The GM
IiI bases window motor end position on current
draw (load). There is a maximum window motor run time of
6 seconds. The motor is then switched off even if the end
position load sensor fails.

Door Windows
Window switches
4 The push type window switch provides the GM Ill with a cod-
ed ground signal. Holding a switch at the first detent provides
a single ground signal on one wire requesting the GM
Ill to
open the window. When released, the ground signal is re-
moved and the window motor stops.
- Momentarily pushing the switch to the second detent and re-
leasing provides an additional ground signal on the second
wire requesting "one touch mode". The GM
Ill lowers the win-
dow automatically until it reaches the end position. Each win-
dow has four positions, two each for the standard mode of
operation and two for the one-touch mode. All window oper-
ation signals are digital inputs to the door modules and GM
111.
- The switch functions in the same manner for window closing
but the ground signal sequence is reversed.
4 Window switch positions.
1. Off
2. Open
3. One touch open
4. Close
5. One touch close
Rear window child lockout switch
4 The rear window child lockout switch (arrow) is incorporated
in the driver's window switch block in
leit front door arm rest.
When activated, it provides a constant ground signal to the
GM
Ill, preventing the windows from being operated from the
rear door switches.
- The lockout switch ground signal is overridden by the GM Ill
if a passive safety system (MRS) crash signal is received.

I Door Windows
/ Anti-trap strip
Power window motors
The window motors are mounted on cable regulators. The
window motor control circuit consists of two wires for operat-
ing the motor in both directions.
The motors are activated by relays in the GM
Ill. The relays
provide either power or ground depending on the direction of
window travel. The GM
Ill controls the polarity based on a re-
quest to run the window from a window switch or a conve-
nience
openinglclosing signal.
Convenience openinglclosing
The GM Iii provides the convenience openlclose feature, pro-
viding control of the power windows (and sunroof) from out-
side the vehicle with the key in the driver's door lock. The FZV
(remote key) provides the same function for window opening
only.
Anti-trap protection is active during convenience closing from
the driver's door lock.
If the GM receives a request to operate convenience closing
or opening for more than
110 seconds, the function is deacti-
vated and a
fault code is stored.
Window anti-trap protection
4 A rubber pressure guard is located at the top edge of each
door frame. It consists of two contact strips that close when
subjected to pressure. When the contact strip closes (for ex-
ample, a hand is trapped between the top of the window and
the door frame), an anti-trap signal is sent to the GM
Ill. The
window immediately (within
10 milliseconds) reverses direc-
tion. This feature does not require
initialization.
The E39 pressure sensor finger guard has a resistance of 3
Kw and it is monitored for open circuits. When pressed, the
monitored resistance changes to
< 1 Kw. if anti-trap protection
becomes faulty the one touch window closing will not func-
tion.
Window anti-trap protection is
only active in the one touch
and convenience close modes of operation. If the window
switch is pulled and held, anti-trap protection will not function.
The anti-trap contact strip has a resistance of
1.2 K Ohm and
it is monitored for open circuits. Faults with the anti-trap sys-
tem will cancel the one touch feature requiring the window
switch be held to close the window.

lnterior trim repairs
lnterior trim and finish panels are clipped or screwed into
place. Many of the trim retaining clips are designed
to be used
only once. When removing trim that is held in place with clips,
it is a good idea to have spare clips on hand before beginning
the job.
WARNING-
Special precautions must be observed when servicing the
BMWSupplementai Restraint System (SRS). Serious inju-
ry may result if system service is attempted by persons un-
familiar with the BMW
SRS and its approved service
procedures. BMW
speciiies that all inspection and service
should be performed by an authorized BMW
dealer.
Before performing any work involving airbags, discon-
nect the negative
() battery cable. See 721 Airbag
System (SRS).
Airbags contain a back-uppowersupply within the SRS
control module. A
5 second discharge period should be
allowed after the battery cable has been disconnected.
CAUTION-
* When working on electrical switclies or lights, always dis-
connect the negative
(-) cable from the battery and insu-
late the cable end to prevent accidental reconnection.
a Prior to disconnecting the battery, read the battery dis-
connection cautions given in
W1 General Warnings
and Cautions.
To prevent marring the trim when working on interior
components, work with plastic prying
tools or wrap the
tips of screwdrivers and pliers with tape before prying
