X3 M, X5 M, X6 M, Z3 M & Z4 M
So my check engine light came on over the weekend. System check is all ok. Car driving perfect and gas mileage is fine. Thought maybe it was the gas cap, that was fine. Took it to my mechanic and he says it says cylinder 1 is misfiring. It has 80,000 miles on it. I’ve owned it less than a year...
