SUBJECT:
M60 DME Engine Control Module EPROM Programming Update (Without EWS II)
MODELS:
E31, E32, E34 and E38 vehicles with M60 engines with automatic transmissions produced prior to 1/95
Situation:
M60 vehicles without EWS II which were updated using programming software 5.1 may encounter the following customer complaint:
^ 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.O 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 minutes of vehicle operation under various load conditions.
1. A replacement Engine Control Module EPROM must be determined by following the procedure provided in S.I. 12 07 95 (4273).
2. Replace the EPROM in the control module by following the procedure given in S.I. 12 08 95 (4274).
