[s-cars] HVAC Reading in Celcius how to change

[Feico van der Laan]

Folks,

If anyone can help me here that would be greatly appreciated. These issues are not related and pertain to an early 1992 S4 (AC compressors are different).

1) HVAC has been reading in Celsius for months after a bad battery ... does anyone know how to change it back?

2) Recently I have the following codes and the AC does not work because the HVAC system turns it off.
00604 
30-00
Pot. positioning motor for air flow flap G113 

01270 - A/C Magnetic Clutch
42-10 - Speed Deviation too High - Intermittent

The AC clutch does engage in the VAG-COM output test.

If anyone is familiar with these issues and I may not need a new compressor let me know!

Thanks,
Feico
