: A/C Issue

06-19-2012, 06:06 PM
Good day all, I have a 04 Avant that was blowing hot air at start up. A/C was working fine when I went to work. This has happened once before. After pushing different buttons on the climate control unit it began to work after a few minutes. Blew COLD all the way home. Got home and hooked up VAG-Com and the A/C would not blow cold air. I received the code below, can anyone give me any ideas before I have to take it to the stealership. Also can anyone tell me is there any difference from taking it to the Audi or the V/W shop? I have a V/W shop close if I cant fix myself. SOrry for the rant the code is below.

The code simply states that the Control Module in Instrument Cluster has a stored DTC (diagnostic troubleshooting code); you'll need to drill-in to the sub-module within the ECU hierarchy with the VAG-Com in order to determine which fault-code has been registered. :huh:

Thanks for the help! I a getting ready to register the Vag-COM lite to open up some of the options I cant get right now. The A/C alaways comes on just when it want to after startup. Once on it's like a refrigerator in the car. This is my first German car and am just starting to get into the wokings of it.
