Car Won't Pass Inspection?
I have a 2009 M3 sedan with a dealer installed Dinan exhaust and tune. It's still under warranty and it drives great. I went to get a state inspection almost two weeks ago at my dealer. They told me my car didn't pass inspection because the O2 sensor and the catalytic converter sensor were registering as "not ready". They told me I needed to drive my car through a specified driving profile (5 minutes idle, 10 minutes 2-40 mph, 15 minutes 40-60 mph, etc). I did what they asked and it didn't help. So they kept my car so the mechanic could drive it. Anyway, it's been a week and a half and they've only cleared one fault. Now they're telling me one of the ECUs(?) may not be communicating correctly and may need to be replaced under warranty. Has anyone else had a problem getting their M3 to pass inspection?
