16 Fault Codes/Misfires Need Help

RoyalFlushness · 10-26-2015, 07:42 PM

Hey guys,

I have an 08 m3
Mods:

- X pipe/ not cats
- Miesterschaft exhaust
- Active green filter
- BPM Stage 2 tune with Overrun

I was driving last week, the car started misfiring like crazy, I pulled over. Turned the car off. Turned it back on, then everything was fine. Scanned the car, and al these codes came up. Cleared the codes thinking it could have been bad fuel or something, and it started misfiring today slightly at low rpm. It only happened for a few minutes then stopped. Check engine light came back on an hour later. Any input?

Looks like a bank one oxygen sensor to me. You have 3 codes for the same sensor, and all of the misfires are on that same bank except one.
