Scan the HVAC Controller.
The label file is different to the FSI file. But, again, like the FSI, there is no label file in Lite for the version of the HVAC thats fitted to the A2, (all of them I believe). The correct label file is included in the full version of VCDS, but only in German, but translates OK.
The scan will probably tell you what's up, or maybe, like me and Teresa, you may find a comms error to the HVAC Controller. I cleared mine, and Teresa's, with OBD Eleven. VCDS may work, once the label file is installed, but I'm not sure whether the label file is used for scanning.
Install the
@Andrew file in the label folder, same as the FSI one, then scan the HVAC, and,
Clear Faults.
