Forgive me if this topic has been covered previously. I tried doing a search but unfortunately I couldn't find anything
I have a major problem with my 1993 325i and I was hoping one of you pros can tell we what could be wrong with my car.
While driving the TCM (transmission control module) sign comes on it's the light with exclamation mark with gears around it. I think it's the TCM light. Now here's where it gets weird. Once I stop the car, turn the engine off and wait few sec then start back on the light goes off and the car drives normal. I have noticed that this usually happens when I make a hard stop or hit a bump.
Can some please advice on what could be wrong. Is it possible it's the speed sensor or the ABS sensor??
If that wasn't enough now my car is guzzling gas like anything. Just this past weekend I filled up the gas tank and did local driving for 6 - 7 miles and the car exhausted quarter tank of gas.
