My Audi you simultaneously hit the Recirc and off buttons for 2-3 seconds and the HVAC temp and the outside temp display in the instrument cluster both turn to Celsius.
The issue with the German cars (VW and Audi in particular, I have a VW Golf R32 and an Audi Allroad) were in changing the clock to 24 hour but keeping miles without it changing also to Imperial gallons. My BMW 540i changes to 24 hour time via the menu in the radio/computer. Easy as pie. I never tried to change it to Celsius.
