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 drivers door pillar and in the owners 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 tires 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 cars 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
020-30 Maintenance fluid use and the most-up-to-date information regarding transmission operating fluids. The automatic transmission is not equipped with a dipstick. Therefore, checking the ATF level is an involved procedure which includes measuring and maintaining a specified ATF temperature during the checking procedure. For more complete ATF service information, including checking ATF level and ATF filter replacement procedures, see 240 Automatic Transmission. Transmission service, manual Manual transmission service consists of inspecting for leaks and checking the fluid. Evidence of transmission leaks is like- ly to be seen around the driveshaft mounting flange and at the bottom of the bellhousing.

Maintenance BODY AND INTERIOR MAINTENANCE Body and hinges, lubricating Door locksand loclccylinderscan be lubricated with an oil that contains graphite. Body and doorhinges, hood latch and doorcheclc rods should be lubricated with SAE 30 or SAE 40 engine oil. Lubricate seat runners with multipurposegrease. Do not apply any oil to rubber parts. If door weather-strips are sticking, lubricate them with silicone spray or talcum powder. The hood release cable should be lubricated as well. The use of winter lock deicer sprays should be lkept to an absolute minimum, as the alcohol in the deicer will wash the grease out of the lock assemblies and may cause locks to corrode internally or to become difficult to operate. Exterior washing The longer dirt is left on the paint, the greater the risk of dam- aging theglossy finish, eitherby scratching or by thechemical effect dirt particles may have on the painted surface. Do not wash the car in direct sunlight. If the engine hood is warm, allow it to cool. Beads of water not only leave spots when dried rapidly by the sun or heat from theengine, but also can act as small magnifying glasses and burn spots into the finish. Wash the car with a mixture of lukewarm water and a car wash product. Rinse using plenty of clear water. Wipe the body dry with a sofl cloth towel or chamois to prevent water-spotting. Interior care Dirt spots can usually be removed with lultewarm soapy water or a dry foam cleaner. Use spot remover for grease and oil spots. Do not pour the liquid directly on the carpet or fabric, but dampen a clean cloth and rub carefully, starting at the edge of the spot and working inward. Do not use gasoline, naphtha, or other flammable substances. Leather upholstery and trim Leather upholstery and trim should be periodically cleaned using a slightly damp cotton or wool cloth. The idea is to get rid of the dirt in the creases and pores that can cause brittle- ness and premature aging. On heavily soiled areas, use a mild detergent (such as wooliteQ) or other specially formulat- ed leather cleaners. Dry the trim and upholstery completely
020-32 Maintenance using a soft cloth. Regular use of a good quality leather condi- tioner will reduce drying and cracking of the leather. Polishing Use paint polish only if the finish assumes a dull loolc afler long service. Polish can be used to remove tar spots and tar- nish, but afleiwards a coat of waxshould be applied to protect the clean finish. Do not use abrasive polish or cleaners on aluminum trim or accessories. Seat belts Dirt and other abrasive particles will damage seat belt web- bing. If it is necessary to clean seat belts, use a mild soap so- lution. Bleach and other strong cleaning agents may weaken the belt webbing and should be avoided. WARNING- Do not clean the seat belt webbing using dry cleaning or oth- er chemicals. Allow wet belts to dry before allowing them to retract. - The condition of the belt webbing and the function of the re- tractor mechanisms should be inspected. See 720 Seat Belts for seat belt inspection information. Speciai cieaning Tarspots can be removed with a bug and tar remover. Never use gasoline, lterosene, nail polish remover, or other unsuit- able solvents. Insect spots also respond to tar remover. A bit of baking soda dissolved in the wash water will facilitate their removal. This method can also be used to remove tree sap spots. Washing chassis Periodic washing of the underside of the car, especially in winter, will help prevent accumulation of road salt and rust. The best time to wash the underside is just afler the car has been driven in wet conditions. Spray the chassis with a pow- erful jet of water. Commercial or self-service carwashes may not be bestforthis, as they may recycle the salt-contaminated water. Waxing For a long-lasting, protective, and glossy finish, apply a hard wax after the car has been washed and dried. Use carnauba or synthetic based products. Waxing is not needed after every washing. You can tell when waxing is required by look-
ing at the finish when it is wet. If the water coats the paint in smooth sheets instead of forming beads that roll off, a new coat of wax is needed. Waxshould not be applied to black trim pieces, rubber, or other plastic parts. Windshield wiper blade maintenance Common problems with the windshield wipers include streak- ing or sheeting, water drops afler wiping, and blade chatter. Streaking is usually caused when wiper blades are coated with road film or car wash wax. Clean the blades using soapy water. If cleaning the blades does not cure the problem, they should be replaced. BMW recommends replacing the wiper I blades twice a year, before and after the cold season. I < To replace wiper blade, depress retaining tab (arrow) and slide blade out of arm. I - Checlc tension spring that forces wiper against glass. Re- place wiper arm if spring tension is weak. Drops that remain behind after wiping are caused by oil, road film, or diesel exhaust coating the windshield. Use an alcohol or ammonia solution or a nonabrasive cleanser to clean the windshield. Wiper blade chatier may be caused by dirty or worn blades, by a dirty windshield, or by bent or twisted wiper arms. Clean the blades and windshield as described above. Adjusithe wiper arm so that there is even pressure along the blade, and so that the blade is perpendicularto the windshield at rest. Lu- bricate the wiper linkage with a light oil. The linkage is located under the hood on the drivers side. If the problem persists, the blades are excessively aged or worn and should be re- placed. See 61 1 Wipers and Washers for more information.

See Table a. Table a. Engine specifications
Engine identifying features 4 The M52 engine (MY97-98 528i) used a single on-off vari- able intake valve timing system (called VANOS). The cylinder block is cast iron and the cylinder head is aluminum. The en- gine management system is Siemens MS 41 .I and features NGK-type (0-5 volt) oxygen sensors. NOTE- VANOS is an acronym based on the German words Variable Nocltenwellen Steuerung (variable camshaft timing). 4 The M52 TU engine (MY99-00 5281) and the M54 engines (MY01-02 525il530i) are fitted with double VANOS. The en- gine blocits are constructed of aluminum alloy with cast iron cylinder sleeves. 4 The double VANOS (variable camshaft control) system incor- porates true variable control of both the intake and exhaust camshafts, as compared to the single VANOS system on the M52 engine (onloff control of the intaite camshaft only). The M54 engines use a fully electronic throttle control (drive by wire). There is no accelerator cable connecting the throttle pedal to the throttle housing in these cars.
100-4 I Engine-General The M62 90 V8 engine uses four valves per cylinder, double overhead camshafts and light alloy cylinder head and cylin- der bloclc engine construction. On 1997 and 1998 540i models, Bosch engine management systems are utilized. Table a lists engine management sys- tem applications. 4 For the 1999 model year, the M62 TU VANOS engine was in- troduced to the 540i models. This engine is primarily a carry- over from the earlier M62 engine, but contains many unique identifying components and technology: Variable camshaft timing (VANOS) for the intake valves. Bosch ME 7.2 engine management system with electronic throttle control. There is no accelerator cable connecting the throttle pedal to the throttle housing in these cars. Compact water-cooled generator (alternator). E39 vehicles are equipped with sophisticated self-diagnostic engine management systems. These systems monitor and store diagnostic fault information. If the malfunction indicator lamp (MIL) illuminates, the first diagnostic test should be to connect a dedicated scan tool for BMW automobiles and in- terrogate the fault memory. If the malfunction indicator light (MIL) comes on orflashes, it indicates that an emissions-related fault has occurred and that fault information is stored in memory within the ECM. 4 The MIL in E39 cars displays one of these warning graphics in the instrument cluster. The diagnostic capabilities of these systems have the poten- tial to save hours of diagnostic time and prevent incorrect 5 placement. See OBD On-Board Diagnostics.
