V8, Built 2007 Hello, it is hardly a problem (tire sensor) solved, comes already the next. Human, is that so with all high-tech cars so ? Aircon blows only hot air. All diodes are on, do not flash. In the error memory (with VCDS) nothing is reported. All fuses are OK. Pressure sensor connected: constant approx. 6,5 , does not rise with switched on AC. That is. The compressor is not filled but the compressor runs. Can it be that the magnetic coupling does not couple , i.e. not electrically connected and that the copressor is not running? Again the question :what to do ? Thanks for good ideas Jag
