Do not use these tools to tighten fasteners, especia ll y on li ght alloy parts. 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 wi th 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). Do not subject to temperatures in excess of 185° F (85° C} fo r 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. • Make sure i gnition is switched OFF before disconnecting battery. • Label battery cables before disconnecting. On some models. battery cables are not color coded. • Disconnecting the battery may erase fault code(s) stored in control module memory. Using special BMW diagnostic equipment, check for fault codes prior to disconnecting the battery cables. If the malfunction indicator light (MIL) is illuminated, see 080 On-Board Diagnostics at the back of this manual. (This li ght may be identified as the Check Engine light or the Service Engine Soon light.) If any other system faults are detected (indicated by an illuminated warning light). see an authorized BMW dealer. • If a normal or rapid charger is used to charge battery, disconnect the battery remove it 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 l east one minute before boosting the battery a second time. • Connect and disconnect a battery charger only wi th the battery charger switched OFF. • Sealed or "maintenance tree" batteries should be slow-charged only, at an amperage rate that is approximately 10% of the battery's ampere-hour (Ah} rating. • Do not all ow battery charging voltage to exceed 16.5 vo lts. 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. • Do not use steel fasteners on engine components made of aluminum-magnesium alloy. Use aluminum fasteners only. Test fasteners for aluminum composition wi th magnet. • Replace aluminum bolts each time they are loosened. Follow torque instructions, i ncluding angle of rotation specifications, when installing aluminum fasteners.

002 Vehicle Identification and VIN Decoder 002-1 Some of the information in this manual applies only to cars of a particular model year or range of years. For example, 2004 refers to the 2004 model year but does not necessarily match the calendar year in which the car was manufactured or sold. To be sure of the model year of a particular car, check the vehicle identification number (VIN) on the car. The VIN is a unique sequence of 17 char acters assigned by BMW to identify each in dividual car. When decoded , the VIN tells the country and year of manufacture: make. model and serial number: assembly plant and even some equipment speci fi cations. The BMW VIN is on a plate mounted on the 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. Example: 4 for 2004. For 2010, A is used. The table below explains some of the codes in the VIN for 2004 through 2010 BMW E60 and E61 5 Series cars covered by this manual.

NOTE - • For vehicles with the factory alarm, opening the door will activate the alarm. Oil residue may collect on the cylinder head cover near the oil filler cap a few days after topping up or refilling the engine oil. When oil is added, the filler cap is laid partially upside down. In this position. engine oil seeps into the area of the oil cap that is not sealed by the gasket. When the cap is reinstalled. the oil leaks from the unsealed area onto the cylinder head cover surface. If investigating an oil leak in this area, confirm that it 1s not oil from the cap.

On the VS engines, there is no tensioner on th e A/C belt. To insta~ new belt, a special tool (BMW part # 90 88 6 641 040} is required to guide the belt onto the pulley. When installing a new battery. it must be "registered" to the vehicle to notify the vehicle power management software (engine electronics and intelligent battery sensor} that a new battery was fitted. This operation requires a BMW scan tool. Without new battery registration, various electrical problems as we ll odd electrical system behavior can occur. 020 020 121

003-4 Symptoms and Field Observations 0 GENERAL DATA AND MAINTENANCE (CONTINUED) I ~~~~~~~~~--.- A - dd -m- .onal ~~~~ Topic Notes information - (when available) Intelligent battery sensor (IBS), serv ice precautions When performing diagnosis on a vehicle with the BMW scan tool, the message "Connect diagnostic connector and switch ON Ignition (Terminal 15)!" is displayed. • D-CAN failure in vehicle. Before diagnosing D-CAN in th e vehicle, try communicating with another vehicle. If communication cannot be established on other vehicle, try a different scan tool. If communication resumes on the other vehicle, use the following steps to diagnose DCAN. - Disconnect vehicle power supply I charger (if connected). - Disconnect battery. - Check resistance of D-CAN circuit across OBD socket Pin 6 (D_CAN_H) and Pin 14 (D_CAN_L). A good D-CAN measures 60 ohms. The D-CAN circuit is fitted with two 120 ohm terminal resistors. One is fitted in wiring near OBD socket. The second is fitted in gateway module of vehicle (KGM or SGM). - If resistance reading is O ohms, the D-CAN wires are shorted together. Check circuit for shorts as per wiring diagram. - If resistance reading is Mega ohms, the D-CAN wiring has an open circuit. Check circuit for opens as per wiring diagram. - If resistance reading is 120 ohms, one of terminal resistors is faulty. Check resistance of both resistors for an open circuit and replace as necessary. The Intelligent Battery Sensor (IBS) is an electronic device connected directly to the negative battery terminal.The IBS is ve ry sensitive to mechanical stress and strain. Particular attention should be paid to the following points: • Do not make any additional connections at the negative terminal of the battery. • Do not modify the battery ground cable. • Do not make any connections between the IBS and the sensor screw. • Do not use force when disconnecting the ground terminal from the battery. • Never pull on the ground cable. • Do not use the IBS as a pivot point to lever off the ground terminal. • Do not use the connections of the IBS as a lever. I • Use only a torque wrench as described in the repair manual during installation. • Do not release or tighten the sensor screw. NOTE - • A replacement I BS includes lhe ground cable. The ground cable also serves as a heat dissipater for the IBS. 020, 600 121

1 ENGINE Topic Engine knock fault codes Diagnosing electric cooling fan E- box water ingress No crank, no start Symptoms and Field Observations 003-5 I Notes I Additional infonnation I (when available) Engine knock fault codes indicate that the engine is knocking. Detonation or knock is an erratic form of combustion that can cause head gasket failure as well as other engine damage. Prolonged or heavy detonation can be very damaging. The hammer-like shock I waves created by detonation subject the head gasket, piston, rings, spark plug and rod bearings to severe overloading. As a first remedy, try higher octane high detergent fuel or switch brands. If the faults I codes continue to return, contact your authorized BMW dealer. From 03 / 2007 production vehicles: A revised power supply relay i- for the electric coolant fan power supply was used on these vehicles Coolant fan power supply relay K9137 is located in the back of the rear fuse box. Connector (B) provides control signals for relay activation (KL30g from the rear fuse box/power distribution box and local ground KL31). 120 On cars with inoperative electric coolant (with symptoms of A/C malfunction, engine overheating. or fault code 2EFE "Cooling fan activation" stored in the DME), check the power supply relay operation: 170, ELE Cheok that both B+ connections (A) are threaded on tight and free of corrosion. Check KL30g (B+) and KL31 (ground) signals (B) for correct operation. Water leaks into the E-box may cause various drivability complaints, loss of power or the ..
