Danny, I'm new here but interested in your seats conversion: I've put Audi A6 S-line heated seats in my Skoda Octavia. Wanting to connect up the heated elements and bought a car wiring loom and new climatronic panel, but turns out the Audi seats seem to use a different system of controlling the seats. On VWs/Skodas there is a 'heated seats control module' under one of the seats, but nothing on my Audi seats, seems I need one of these modules and a mini wiring loom under each seat.
Did you ever get your heated seats heating: I'd be really interested if you have done or have any words of wisdom!
