When I get into my car and press the fan button, choose a speed, sometimes when I look back at it, the car has decided that I didn't want '3' or '5' or whatever I chose and gave me '7' or some other random speed
Any idea why it speeds the fans up sometimes?
Its a 2010 S4 (b8). TBH I find the whole heater system unnecessarily complex. All those little menus flying on then off. Whats wrong with simple dials? Tech gone mad that.
