Content Inside :
Contain various problems for BMW vehicle, the symptom, cause and solution. Part of content : INITIAL DRRIVEABILITY MODELS AFFECTED: 1982 633CSI/733I; 1983 533I/633CSI/733I; 1984 533I/633CSI/733I FAULT: Hesitation /poor throttle response in first 5 to 10 min of operating after Starting a cold/warm engine at an ambient temperature above 75 deg f. CAUSE: The new generation Montronic Control Unit was not sufficiently re-programmed to compensate for the removal of the external 560 ohm resistor. SOLUTION: Installation of an external resistor in the NTC line. ENGINE SPEED APPEARS TO HANG DURING SHIFTS MODELS AFFECTED: E46-323i with M52 TU engine & manual trans produced 4/98-3/99 E39-528i/iT withM52 TU engine and manual trans produced 9/98-3/99 Z3- with M52TU engine and manual trans produced 8/98-3/99 FAULTS: -During shifts engine RPM momentarily hangs up. -Gear change is not smooth 1-2&2-3 shifts. CAUSE: -DME is not receiving the clutch depressed signal. -When the clutch pedal is depressed the program within the ECM/DME doesn’t allow the engine to speed to drop quickly. SOLUTION: Check the DME is receiving the signal from the clutch switch and the DME may. ENGINE CRANKS BUT DOES NOT START MODEL AFFECTED:Z3(E36/7) from 9/98 production FAULT: Engine cranks but doesn’t start. The fault code 209(decimal) or d1 (hex) (EWS/DME alignment) is set in the DME. CAUSE: EWS 3D module SW version O5. has software error. SOLUTION: EWS module to be removed which is located on the left side of the vehicle, below the instrument cluster, and replace with EWS 3D module SW version 06.(part no 61 35 4 101 593).Code the EWS module using DIS V16.0 or later.
