I have a 997 C2S.Problem with my heated seats.Driver & passengers side not working,went to a Porsche specialist he said they had not been programmed to work.He said he did not have software to do this.Talked to Porsche West London they said never heard of this problem.But if that was the case it would be £120.00 for the hour + vat to fix.Also headlight washer not working & cd changer in glovebox not being recognised by main unit.Is this all connected ? Can anyone shed any light on this fault.Don't want to pay a fortune to Porsche to fix it.
