2F83 & 2F81 are missing from the list. Per Google translate:

2F83: Engine shut-off time, Time counter Instrument Cluster - Time counter DME, Comparison
2F81: Engine shut-off time, Time counter Instrument Cluster - Time counter DME, Comparison

Can anyone elaborate on the solution for 2C32? I'm getting this code along with 2C6C-Oxygen Sensor 2 after Cat Converter
2C3211314Lamba probe in front of cat 2, trimming controlo2 sim to strong. Raise o2 modifier setting
[TBODY] [/TBODY]
Newly installed Doc kit within 1000 miles. I figured I burned up the sensor, so I replaced pre-cat bank 2 o2 (with NTK) to no resolve. Ordered and plan to replace post-cat downstream o2 (Bosch) this weekend. Research points to a bad post-cat sensor can throw codes for pre-cat or a possible exhaust leak. No major leak detected.

I'm assuming raising o2 modifier setting is something my tuner will need to do (MHD).

Trying to come up with a checklist of things to consider while I tear into this weekend. I can provide idle and cruising logs.

Happy to start a new thread if needed.
