Pulled over and checked the door, it was tight and nothing seems amiss. Switched off the engine and start again and the warning light disappeared. Only yesterday, the light bulb faulty light came on. Checked and did not see any blown bulbs. So not sure why this random warning lights start appearing without any reasons.
Is this a software bug? Any one has similar encounters? Anyone done a ECU software remapped?
Hope it's not an electrical short problem. I had a friend that had a 325cic and had all sorts of warning light issues, then it turned into an "electrical short". Long story short, it just got worse. There were times the car would not let him in or out when he tried to unlock it. Car turned in as a Lemon or in BMW's terms, "a buy back".
