Dear brother 320Ds,
Am not an active member, not mistaken been a member since 2012.
I have been sending my car to Ingress for scheduled services and check up. Now that the car has clock more than 100k, the BSRI is over.
Last Saturday I sent my car to Andy of Eastcos Auto, Bkt Jalil due to leaking of my water tank, connector and also to replace cracked vibration damper (I was told that this is common to a diesel car). The issue was, when they connect back the negative plug of battery (Andy told me this is SOP to remove the negative plug), there was a notification "lighting system failure, stop carefully". All my lighting system has malfunction. they ran diagnosed on it and apparently according to Andy, my lighting control module (LCM) is faulty and this problem always happen to E90. He offered me to leave the car and to fix the LCM instead of replacing it, I told him I'll send it back to him on Monday to fix it. So this morning I sent the car and leave with him to fix the LCM, which according to him will either done today or tomorrow.
What worries me, he said there is a possibility of 5% after they fix and recoding back the data, another module might be affected. Am at my wit end now, am not sure whether all these are true or 'kena game'. I don't want to trouble you guys but have no choice but to ask all the Otai2 here, have you guys encounter same issue, whether is true the SOP to disconnect the negative plug before work on the replacement and fixing/recoding the modukle might affect the other control module. Appreciate any hand on this trouble state of mine.
Cheers!
