I've received great help here when starting out with VCDS so I thought I'd ask here again. Hope it' OK and if not point me to the correct part of the forum
There's no A/C in my Audi B5S4. There's no sound of the solenoid engaging the clutch on the compressor and not even a slight increase in engine speed when pushing the Auto A/C button. There are no fault codes shown for the 08 Address: Auto HVAC. Although access to the A/C compressor is tough, before I put 12 volts across the solenoid to see if the clutch engages, I wondered if there's any analysis with my VCDS HEX-NET that might reveal whether the problem is the solenoid, the relay. or other component of the A/C system or the clutch itself?
