Now I defo do not have a convertible and I thought that the aux air heater was only fitted to diesels. Any thoughts?
Also noted that the faults were registered on 15th May, I've cleared them but have not been out for a drive yet to see if they return. It may be a coincidence but that was 5 days after the bluefin map was done.
