Ac doesn't blow cold when at idle but anything above 1,500 RPMS it blows cold. Pressure is fine, clutch engages, both fans are working, and the condenser is clean.

Any thing I can do to fix this or is it just an Audi thing?

 

I have the same problem. Going down the road I'm fine. Stopped at a light, no bueno.

 

I'm not even saying down th road, I just press the gas in park and cold air from the higher rpm.

Check your secondary fan

 

so u checked for leaks and everything. I would think it might since the car is sitting at idle the compressor is having to work overtime to cool air and no cool air is hitting the condensor coil. . I thought most ac's do this a bit while at idle.

 

you most likely have a low charge.... an a/c service is recommended over those top of bottles.

 

Yea those over the counter bottles arent very good. If u do recharge let a professional do it.
