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. Disclaimer We have endeavored to ensure the accuracy of the information in this manual.

CAUTIONS- See also WARNINGS - 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 dealer 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 specifications. Use pneumatic and electric tools only to loosen threaded parts and fasteners. Never use these tools to tighten fasteners, especially 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 in excess of 203" F (95°C) and should not be subjected to temperatures in excess of 185°F (8S°C) for more than two hours. - Before doing any electrical welding on cars equipped with ABS, disconnect the battery negative (-) terminal (ground strap) and the ABS control module connector. - Always make sure ignition is off before disconnecting battery.

If any other system iaults have been detected (indicated by an illuminated warning light), see an authorized BMW dealer. If a normal or rapid charger is used to charge battery, the battery must be disconnected and removed from the vehicle in order to avoid damaging the vehicle. - Do not quick-charge the battery (for boost starting) for longer than one minute. Wait at least one minute before boosting the battery a second time. * Connect and disconnect a battery charger only with the battery charger switched off. - Sealed or "maintenance free" batteries should be slow-charged only, at an amperage rate that is approximately 10% of the battery's ampere-hour (Ah) rating. . Do not allow battery charging voltage to exceed 16.5 volts. If the battery begins producing gas or boiling violently, reduce the charging rate. Boosting a sulfated battery at a high charging rate can cause an explosion.

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.

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 E39 5 Series BMWs covered by this manual.
