New to this hopefully this works. Bought used 08 A4 2.0 Quattro 221000 miles few things so far replaced crank case vent valve and head gasket.
issues heater on drivers side works but heat on passenger side blows cool air indicator shows being on high
TPMS indicator light is on and pressure on tires have been checked. Checke engine light on was told to replace gas cap ordered one is not audi OEM cap and then was told it needed to be check engine light still on. Thanks for any advice
