I noticed what appears to be the resonator damaged while doing an oil change. I also have had DTC P0430/P0420 which could be due to cats or sensors but I’ve had that code for over a year. What do you think?

Those shaving you see are not from the bolt itself but came from the oil pan. Without the washer the bolt tightens but with it it keeps spinning. Any ideas?

Mabye I’m going crazy but I could have sworn my lights stayed completely off when switched off. But now I can see the halo lights on even when switch in off position. Am I imagining things or has this happened to anyone else. 2001 m5 with 152k miles.
