Hey Bimmerfest, First post, and I'm in a pretty odd situation.
History: I just did a road trip from Delaware to Cali in my 2004 645 (45k miles). Now, before the trip, my car would occasionally stutter before it started, but presented no issue after. Also, the dynamic drive malfunction would appear and disappear randomly.
Fast forward: After about 2500 miles, filling up with only 91, 92 and 93 gas, my "gas cap needs to be tightened" light would appear, but always disappear. Then, while starting my car after a fill up, the car stuttered again, then boom- increased emissions- service engine soon light. At this point I'm in New Mexico heading toward Sacramento.
FF again: While driving through Cali, my window lights would randomly flicker on and off. And when this happened, almost on cue, the dynamic drive malfunction would appear. Increased emissions light never disappeared. The final straw? In Fresno, I pulled over because my idrive screen began to flicker. When I tried to start the car, it would attempt a quick crank, idrive would flicker out of control, then nothing. Eventually the battery died. I had to get it towed to the dealership (terrible look) Thursday, and they can't look at it til Monday. I'm very worried- after reading forums, I would only suspect an O2 sensor, thermostat, coil, and/or power steering fluid to be the issue. However, I'm now in Sacramento waiting to hear the dealer's "professional opinion". Very worried about overpriced repairs. What do you guys think the problem is?? Please help. What should I do?
