We have had a 2003 Audi A4 Avant for a little while now, and since we have owned it, its never really blown out hot air from the heaters.
And at this time of year, you can guess why we are getting annoyed that its not working, its freaking freezing! haha
A little while ago it had a water pump change and it blew mildly warm air but not for long, it soon went back to its cold self!
Does anyone have any ideas on what to check or what could be the culprit of our problem??
Iv head there is a valve that can go that feeds the heater matrix?
Anyone able to helop identify it and find a part number? im looking here Audi A4/Avant 2003 but I cant see anything obvious!
Its a 2.0L Petrol engine.
