Well I did a VCDS scan and J126 Blower controller has thrown a few fault codes lately so it does appear to be the likely suspect. I can get a third party one from Germany for around £100 plus delivery, or perhaps risk a used one from A8parts.
J126 is the electronic resistor circuit.

Looks a right ballache to change however.
