I've had my new S3 for about a week now, it's done 450 miles from new, and it's amazing!
However, I just took the wifes TT out for a spin and her heated seats almost burnt the skin off my arse, in comparrison to my car.
In fact, I'd challenge if they work much at all.
Is this normal with the A3 / S3 ? Or can someone here confirm that they should get quite warm.
