The condenser had corroded and leaked causing it to stop working. Audi dealer and Halfords were useless. I got an independent Air con specialist to diagnose it and do the work. Cost around £500 for diagnosis, fit new condenser and re-gas.

Hi did you manage to get to the bottom of it? I'm having the same issues

I've got a 66 plate A4 avant. Recently the air con is showing as off when the engine is on. When I try to change it to on or eco they are greyed out and I can't select them. I can select eco or on when just the ignition is on but I'm not sure if it's actually working. After a bit of googling it either needs as regas, a new pressure switch or an new compressor. Anyone else had any similar problems??
