so, with 4 weeks of ownership under my belt, the air con has suddenly stopped working on my 2004 B6 S4 Cab. I think the compressor has gone FUBAR, as VCDS reports 5.0 BAR at rest, only rising to 6.0 BAR when aircon set to LO. I thought this should be much higher? (outside temp measured at 18degC). The 2x pipes running from engine bay into cabin are of equal temperature and not that cold. Any ideas?
