hello guys, im new here but not new to the vw and audi world. I owned passat and a tt and now i own a4.
My 18t a4 has been overheating lately when im parked and have the ac on. The fluid is good, the fans work propertly, everything looks good, car runs fine and doesnt overheat while driving. The temp here is about 96 today. Does anyone one know while this is happening????

i had a 02 and a 99 passat and they never overheated with the ac on on the hottest days. Thanks

 

I know you said the fans are working but I just want to make sure. When the a/c is on both fans turn? If so is there anthing blocking the radiator. You could have a water pump coming apart that just doesnt flow what it should. Just a hunch
