Scanned car with vagcom no codes!, scanned car with launcg diagnostic and had a code for "refrigerant pressure low". Checked the system which was full and no leaks so replaced the pressure sensor rechecked and no codes however i still dont get cold air and the fans dont come on but, when i press the econ button to either turn on or off the revs do fluctuate at idle as if its working so can shed some light on what my problem is
