I purchased the car not too long ago with no visible or apparent problems. The first weekend I had the car I took the car down to South Beach, 30 minutes from my house, and it overheated, at which i point I pulled over and had the car towed to the dealer, which was Champion Audi and Porsche... They replaced a hose and checked the fan (after I told them the fan was not coming on). They told me the fan did not have a problem. Well I drove the car about 3 more weeks and it would overheat but only when sitting at idle. So finally I took the car back and they reported there was still no problem. I then waited another week and finally took my car to thier other location, which is the biggest and supposedly best Audi service center in the world. This time I was satisfied with the rep and the mechanics as they attended to my every need and found numerous things they replaced under warranty to include... water pump, timing belt, various hoses and acc belt, coolant tank, fans, fan motor, MAF, and even my front axles. They also said my car had excessive carbon buildup in the head and tried to and wanted audi to pay for the service, but the head guys said no as they do not cover carbon. Well I got my car back last week and on the 15 mile drive back to work it started to overheat, coolant lights blinking, and cel on (which it did not have when i took it in)
They have checked and replaced thermostats and have had the car over a month now and still cannot come to a conclusion as it still overheats (they have checked the new water pump and everything).
They have never had a case like this and are deliberating on what they are going to do...
Opinions and suggestions on what I should do at this point.. as I really do not like the 2007 A4 loaner they gave me (its a boring drive).
