TECHNICAL SERVICE BULLETIN

Reference Number(s): 12 01 96, Date of Issue: February, 1996

BMW:	E31, E32, E34 and E38 vehicles with M60 engines with automatic transmissions produced prior to 1/95
GROUP:	12 - Engine Electrical

SUBJECT

M60 DME Engine Control Module EPROM Programming Update (Without EWSII)

SITUATION

M60 vehicles without EWSII which were updated using programming software 5.1 may encounter the following customer complaints:

Check engine light illuminates when going downhill and setting Fault Code 201 and/or 203.
Poor acceleration while engine is in the warm-up phase.
Slight vibration during load reversal on 530iA vehicles when accelerator pedal is released and depressed.
Cold start difficulty on 530i vehicles when engine temperature is below 40°C.

CORRECTION

Due to programming modifications as of version 6.0 software, if a customer complaint relating to any of the above is obtained, the EPROM in the Engine Control Module should be replaced and reprogrammed using programming software (disk A & B) V6.0 or higher. Note that once the EPROM is reprogrammed the control module will need time to re-adapt. Adaptation will occur during the first 10-20 inutes of vehicle operation under various load conditions.

A replacement Engine Control Module EPROM must be determined by following the procedure provided in TECHNICAL SERVICE BULLETIN 12 07 95 (4273 ).
Replace the EPROM in the control module by following the procedure given in TECHNICAL SERVICE BULLETIN 12 08 95 (4274) .
