I have a 04 reg A3 2.0 fsi Sport with approaching 60k miles on the clock. A while ago when I started the engine, there was a weird grindy/whirry noise. When I then stopped and restarted the engine, the car was fine, but the air con was no longer blowing cold air. It blows warm air, but i'm not convinced the temperature is a reflection of what is on the digital display. I have just had the car in the garage today (not a dealership) and they have re-gassed the system (apparently pressure was low), found no leaks and also hooked up to the fault code reader, found some faults and cleared them (they haven't explained what these were). The upshot is, the system still isn't working as expected (they confirmed this) - ie. still doesn't blow cold air. I've looked through some of the other threads on here, and don't think this has anything to do with the ECON problem that seems to be prevalent, but happy to be told i'm wrong! Does anyone have any ideas/advice please?
