Questions about codes 2F83 and 2F81

I checked codes with my Cobb AP and I saw these two codes. They both do not have a description and I can't find anything about what these codes are. Just checking to see if anyone else got these codes and/or if anyone has figured out what causes these codes

I had these codes for 1 week and then one day car wouldn't start. I took it to the dealer and they said my diff had blown out. Really odd.
Good luck.

Did anyone figured this out? I have these 2F83 and 2F81 codes on my N52N engine. I used fuel injector cleaner could that cause these codes?

its vanos codes. try cleaning them first with degreaser or brake cleaner and clear the code.

if they come back, just replace them.

in my experience, just cleaning them works most of the time.

on the 1 series, you MIGHT have to take the fan out. but if you have smaller hands, im sure you can wiggle it out

Hello "HOTTER" I'm curious if you ever figured out the 2F83 and 2F81 codes? Because I recently used fuel injector aswell and same codes popped up for me. Or what you may have found the cause to be? Thanks in advance

They are both... "Engine shut-off time, Time counter Instrument Cluster - Time counter DME, Comparison"

Not sure what these refer to, clear the codes and rerun the check again to see if they come back.
