Ross, you say you got the car from your local BMW dealer in November 2016. I apologize if you've answered this before, but have you taken the car back to that dealer and insisted that they at least diagnose and ideally fix this for you?

If you've been taking the car to an independent, I agree that there are guys out there who are scary knowledgeable and skilled in fixing these cars. But sometimes the dealer, who has access to factory-trained technical repair staff and advice, and the full diagnostic equipment, may be the best choice.

By the way, there's no way I'd sell an M Roadster like yours - I'm confident the remaining issues can be fixed.
