Foreword
For the BMW owner with basic mechanical skills and for independent auto service professionals.
this manual includes many of the specifications and procedures that were available to an
authorized BMW dealer service deoartment as this manual went to
Dress. The BMW owner with , no intention of working on his or her car will find that owning and referring to this manual makes it
possible to be better informed and to more
Itnowledgeably discuss repairs with a professional
automotive technician.
If you are a BMW owner intending to do maintenance and repair work, make sure you have
screwdrivers, a set of metric wrenches and sockets and metric Allen and
Torx wrenches, since
these basic hand tools are needed for most of the work described in
this manual. Many procedures
also require a torque wrench to ensure that fasteners are tightened properly and in accordance
with specifications. Additional information on basic tools and other tips are in
010 General. In
some cases, the text refers to special tools that are recommended or required to accomplish
adjustments or repairs. These tools are usually identified by their
BMW special tool number and
illustrated.

trained technicians using approved refrigerant recoverylrecycling
equipment, trained in related safety precautions, and familiar with
regulations governing the discharging and disposal of automotive
chemical refrigerants.
. Do not expose any part of the AIC system to high temperatures
such as open flame. Excessive heat will increase system pres-
sure and may cause the system to burst.
Some aerosol tire inflators are highly flammable. Be extremely
cautious when repairing a tire that may have been inflated using
an aerosol tire inflator. Keep sparks, open flame or other sources
of ignition away
from the tire repair area. Inflate and deflate the
tire at least four
times before breaking the bead from the rim.
Completely remove the tire from the rim before attempting any re-
pair.
Cars covered by this manual are equipped with a supplemental
restraint system (SRS), that automatically deploys
airbags and

- if you lack the slqills, tools and equipment, or a suitable worl(shop
for any procedure described in this manual, leave such repairs to
an authorized BMW dealer or other qualified shop.
BMW is constantly improving its cars and sometimes these
changes, both in parts and specifications, are made applicable to
earlier models. Therefore, part numbers listed in this manual are
for reference only. Always check with your authorized BMW deal-
er parts department for the latest information.
Before starting a job, make certain that you have all the neces-
sary tools and parts on hand. Read ail the instructions thorough-
ly, and do not attempt shortcuts. Use tools appropriate to the
work and use only replacement parts meeting BMW specifica-
tions.
Use pneumatic and electric tools only to loosen threaded parts
and fasteners. Never use these tools to tighten fasteners, espe-
cially on light alloy parts. Always use a torque wrench to tighten
fasteners to the tightening torque specification listed.
Be mindful of the environment and ecology. Before you drain the
crankcase, find out the proper way to dispose of the
oil. Do not
pour
oil onto the ground, down a drain, or into a stream, pond or
lake. Dispose of waste in accordance with Federal, State and
Local laws.
The control module for the anti-lock brake system
(ABS) cannot
withstand temperatures from a paint-drying booth or a heat
lamp

General
ADVICE FOR THE BEGINNER
The tips that follow are general advice to help the do-it-your-
self BMW owner
periorm repairs and maintenance taslts
more easily and more professionally.
Planning ahead
Know what the whole job requires before starting. Read the
procedure thoroughly, from beginning to end, in
orderto know
just what to expect and what parts will have to be replaced.
Workshop practices
Keeping things organized, neat, and clean is essential to do-
ing a good job. When working under the hood, iender covers
will protectthe finish from scratches and otherdamage. Make
sure the car finish is clean so that dirt under the cover does
not scratch the iinish.
Any repair job will be less troublesome if the parts are clean
For cleaning old parts, there are many solvents and parts
cleaners commercially available.
For cleaning parts prior to assembly, commercially available
aerosol cans of parts cleaner or brake cleaner are handy to
use, and the cleaner will evaporate completely.
WARNING-
Most solvents used for cleaning parts are highly flammable
as well as toxic, especially in aerosol form. Use with extreme
care. Do not smoke. Do not use these products indoors or
near any source of heat, sparks or flame.
Non reusable fasteners
Many fasteners used on the cars covered by this manual
must be replaced with new ones once they are removed.
These include but are not limited to: bolts, nuts (self-locking,
nylock, etc.), roll pins, clips and washers. Genuine BMW
parts should be the only replacement parts used for this pur-
pose.
Some bolts are designed to stretch during assembly and are
permanently altered, rendering them unreliable once re-
moved. These are known as torque-to-yield fasteners. Al-
ways replace fasteners where instructed to do so. Failure to
replace these fasteners could cause personal injury
orvehi-
cle damage. See an authorized BMW dealer for applications
and ordering information.

General Tightening fasteners
When tightening the bolts ornuts on acomponent, it is always
good practice to tighten the bolts gradually and evenly to
avoid misalignment or over-stressing any one portion of the
component. For components sealed with gaskets, this meth-
od helps to ensure that the
gasket will seal properly.
WARNING

the table are not intended to be usedas a substitute for tor-
ques specifically called out in the text or in manufacturer's in-
formation.

quence alternating between opposite sides of the compo-
nent. Repeat the sequence until all the bolts are evenly
tightened to the proper specification.
For some repairs a specific tightening sequence is
neces-
sary, or particular order of assembly is required. Such special
conditions are noted in the text, and the necessary sequence
is described or illustrated. Where no specific torque is listed,
Table

Gaskets and seals
Gasket aredesigned to crush and become thinner as the mat-
ing parts are bolted together. Once agasket has been used, it
is no longer capable
;f malting as good a seal as when new,
and is much more likely to leak.
Forthis reason, gaskets
should not be reused.
Some gaskets and seals are
d~rectional. Make sure thatthese
are
~nstalled correctly. In places where a shaft must pass
through a housing,
flex~ble lip seals are used to keep the lubri-
cating
011 or grease from leaking out past the rotatlng shaft.
Seals should never be reused once they have been removed.
When
rernovlng a seal, be careful not to damage the metal
surfaces.
The ltey to seal installation is to get the seal in straight without
damaging it. Use a seal driver that is the same diameter as
the seal housing to gently and evenly install into place.
If a
proper size seal driver is not available, a socket of the right
size will do.
Some seals are directional and special installation instruc-
tions apply. Make sure a seal is installed with the lip facing the
correct way. Note the installation direction of the old seal be-
fore removing it.

General
Torque wrench
A torque wrench is used to precisely tighten threaded fasten-
ers to a predetermined value. Many of the repair procedures
in this manual include BMW-specified torque values
in New-
ton-meters (Nm) and the equivalent values in foot-pounds
(ft-
Ib).
4 Several types of torque wrenches are available. An inexpen-
sive beam-type (top) is adequate but must be read visually. A
ratchet-type (bottom) can be preset to indicate (click) when
the torque value has been reached. They all do the same job,
but offer different convenience features at different prices.
The most convenient ones have a built-in ratchet, and can be
preset to indicate when a specific torque value has been
reached. Follow the wrench manufacturer's directions
for use
to achieve the greatest accuracy.
A torque wrench with a range up to about 150 Nm (1 10 ft-lb) BOIBFNG has adequate capacity for most of the repairs covered in this
manual. For recommended torque values of
10 Nm orbelow,
the English system equivalent is given in inch-pounds (in-lb).
These small values may be most easily reached using a
torque wrench calibrated in inch-pounds. To convert
inch-
pounds to foot-pounds, divide by 12.
Digital multimeter
4 Many of the electrical tests in this manual call for the mea-
surement of resistance (ohms) or voltage values. For safe
and accurate tests of sensitive electronic component and
systems, a multimeter or digital
volt/ohm meter (DVOM) with
high input impedance (at least
10,000Sr) should be used.
Some meters have automotive functions such as dwell and
pulse width that are useful for troubleshooting ignition and
fuel injection problems.
CAUTIOI\C
Vehicle electronic systems may be damaged by the high cur-
rent draw of a test light with a normal incandescent bulb. As
a general rule, use a high impedance digital multimeter or an
LED test light for all electrical testing.

Indicator and warning lights
Many vehicle systems are self-monitored for faults while driv-
ing. Generally,
a red warning lamp that comes on during driv-
ing should be considered serious. If you cannot immediately
determine the seriousness of the warning light, stop the vehi-
cle in a safe place and turn the engine off as soon as possible.
Consult the owner's manual for additional information on the
warning lamp and the recommended action.
If the Malfunction Indicator Lamp (MIL)
(Check Engine or Ser-
vice Engine Soon warning light) comes on orflashes, it indi-
cates that an emissions-related fault has occurred. Faults
such as a bad oxygen sensor or a dead fuel injector can
cause the exhaust or evaporative emissions to exceed a
specified limit. When these limits are exceeded, the MIL will
be turned on. The engine can be safety driven with the light
on, although the emission systems should be
checked as
soon as possible. See OBD On-Board Diagnostics for

4 If oil level is low, add oil by removing oil filler cap (arrow) on
top of cylinder head
(6-cylinder oil cap shown, V-8 is sirnilar).
- Add only amount needed to bring oil level to upper mark on
dipstick, using an oil of correct viscosity and grade.
Engine oil and filter, changing
A complete oil change requires new oil, a new filter insert kit,
and a new drain plug sealing washer. The tools needed, a
17
mm drain plug socket or box wrench, a 36 mm socket or
wrench, and a drain pan (8
- 10 US qt. capacity), are de-
scribed in
010 General.
NOTE-
If using a "fast 1ube"service facility for oil changes, make sure
the technician hand-starts and torques the engine oil drain
plug using hand-tools. Power tools can strip the threads of
the plug and the oil pan.
Run engine for afew minutes to warm engine oil. Shut engine
off.
With car on level ground, place drain pan under oil drain plug.
Using a
36 mm socket, loosen and remove oil filter housing
cover (arrow). Remove filter cartridge and discard any
0-
rings (V-8 engine oil filter housing shown, 6-cylinder oil filter
housing is sirnilar).
Using a socket or box wrench, loosen drain plug at oil drain
pan. Remove plug by hand and let oil drain into pan
(V-8 en-
gine oil drain plug shown, 6-cylinder drain plug is similar).
WARNING -
Pull the loose plug away from the hole quicldy to avoid being
scalded by hot oil. It will run out
quiclcly when the plug is re-
