There is some thing wrong with bank 1. You have a timing problem with the belt or the chain or you have and ignition problem.

The misfire is causing the rich condition

- what is the plugs gapped to ?
- are the coils new from the dealer ?
- have the ignition modules been replaced ...swap them

the cam sensor won't cause a misfire and a rich condition but the timing belt being off timing would cause a rich condition or lean condition and a misfire.

Just like i said before ...... You had a mechanical problem and you did not want to listen to the advice Roll Eyes

I just read on Audizine you found the problem and it was the cam shaft being off time..... Shocked

wow

. Can you please post the details on the repair for other to read in the future.
