    Alternatively your compressor is shot. Not sure if that would come up with vcds errors but it's an expensive part unless you can get one from a scrappy. Thing is, you'll need to get it regassed if it is the compressor.

    is the econ light on the climate controls lit up and will not switch off when pressed if so its the sensor mounted on the side of the aircon radiator behind the front bumper, had this on my 2003 a4 cabriolet ,cost around £35 quid from audi if i remember correctly and is just unscrew old and screw in new unit .


    cheers dav
