has anyone gotten any random Drivetrain Malfunction errors that popped up and went away shortly with no change or vibration or decrease to cars performance? I had my car in once for a few days and dealer was working directly with BMW because they couldn't figure it out. They ended up replacing a knock sensor and all was well for a few days and got the same error again that popped up and went away. I have the car going in now 2nd time for this. I sure hope they can fix this before 4 attempts so my car doesn't get lemoned. I don't want a new car. I searched for 6 months to get this fully loaded spec CPO'd. I don't want it to get bought back or whatever. If it came to that, would BMW replace the car with equivalent car at no cost to me? I can't afford for them to buy it back and try to put me in a new car and pay the difference.
