Hi My wife's Audi 80 air conditioning has given up - the fans work but no cold air, I took it to an independent Audi garage and they would not touch it, they said I needed to go to the Audi main dealer - this sounds expensive! Is there any quick and easy tell-tale techniques to identify the possible fault? Coincidentally (!) the air conditioning seemed to stop working after the car had been into the said independent Audi garage for another repair! This leads to me wonder if the problem with the A.C. is simply a loose cable or AC filter may be causing the problem? A flush of the A.C. system has been suggested to me also - anyone have any idea how much this would cost, or if it would do any good? Any ideas are welcome.
