e90 community,

I've been trying to diagnose a persistent cylinder 6 misfire on my 07 335i. I've replaced plugs and coils within 7k miles, as well as got my index 1 injectors removed and bench tested, which passed with flying colors according to the shop, Vader solutions. I also just replaced the decoupler and seal (both OEM from BMW) on injector #6, as well as sealed it with a little extra Teflon tape. Any help with how to proceed with diagnosis would be greatly appreciated. Attached are some codes that have accumulated after a bit of driving.

185k miles, last walnut blast was at 140k. I have had a burger motor sports catch can installed since 130k.
