Why won't my Audi A4 S-Line's heater produce warm air?
I have an Audi A4 S-Line on a 55 plate. The heater is now blowing out cool air. Can you help? I've had the air conditioning on most of the summer.

Could be a lot of things. Blocked heater matrix, stuck flap, failed control, and if it has climate control a failed cabin thermostat.

Looks classy from the outside and feels classy on the inside. Huge array of engines on offer. Reasonably balanced handling and good ride.
