Started driving yesterday and my "service engine soon" light came on. I know that it could be a million different things but I suspect that maybe someone stuffed something down my tailpipe. I have an 03 330i and i stuffed my fingers in the tailpipe one is clear and the other one has something metal in it in the center. Is anything supposed to be there? I'm going to autozone to diagnose the problem tomorrow but if anyone can answer me that it'll be great.
