After fitting new gear wheels to the mmi new fault codes have appeared
Has anyone had these problems and most importantly know the fixes.

08 Air outlet middle left/right, they all blow air and work with the temp setting in the heating menu but cleared the fault and came back.

09 light switch fault, have noticed the auto dim mirrors not working as ross-tech could be reason. Have turned off all lighting still no change.

Does anyone know how to check the coding for these.
I've googled but not found much.

18 Aux heat this has been making a loud noise when firing up but no fault code until now.

If someone could shed some light on this I would be very grateful.
