dead a/c

mapin · 07-22-2006, 10:17 PM

picked up my a3 from the dealer after its 15K scheduled maintenance. later that day, took her out, turned on the A/C and got nothing but normal-warm air. switching between Econ and A/C did not make a difference, same warm air came out. I called the dealer, he was perplexed since they didn't touch the A/C. I have to bring it in on Monday for them to take a look.

Anybody have any thoughts on this? Is it possible they did something by mistake during the 15K maintenance to cause this? Or just a wierd coincidence? Well hopefully it can fixed quickly.

that happend to my B5 A4 back in the day...I couldn't get the AC to engage unless I hit anything above 3000rpm and I had to maintain >2000rpm to keep it on. It just blew out ambient temp air otherwise. I was told it could've occured as a result of

1) Low refrigerant levels - the powertrain control module will disengage the compressor to prevent internal damage

2) Defective electrically activated clutch - this mechanically links the compressor to a drive belt when the A/C is turned on

Either way, they replaced the clutch and added refrigerant, so I'm not sure what the ultimate cause was. Hope all works out well for you

Had a similar problem. It started with my fans running on after the engine shut off(cold/hot).....forever, unless you disconnected the battery. It wouldn't throw a CEL-then it would but before I could check it with a friend's VAG tool it would clear-this went on for over two months. The dealer had the car for a few days and couldn't figure it out. Finally my ac stopped working(on/off) along with the fan thing and I finally got a CEL that wouldn't clear-"high values to temperature circut"-P0118". They replaced the module which controlds the HVAC and engine cooling-so I was told. No issues since fixed. Only issue in 25k mi.
