I'm starting to think my seat warmers don't work, funny you guys mention it's a common problem.

To the OP - if you think this car isn't going to squeak and rattle, you're in for a rude awakening. All Karmann cars do, it's just a matter of when not if.

I would watch out for relay control modules on cars over 40k miles. None of the dealers know about it and they certainly can't figure the problem out either since it doesn't throw any codes. But it will leave you stranded or even worse the car can die while driving.
