I have a 2006 997 C2 and have had a problem with the door seals going twice now resulting in a soaking wet carpet on the doors whenever the car is washed or left/driven in the wet.
Has anyone else had any similar problems or solutions?
Car has gone into the local porsche centre and they have found a problem with a foam insert in the door which was not sealed properly when they did some work on the windows a while back.
Anyway, new parts ordered and car should be back tommorrow and be all sorted.
Questioning your seal? Carefully put an even application of lipstick or grease paint on seal (rubber weatherstrip) and close door. Make sure it transfers evenly to door frame. If not complain to dealer. Clean off seal.
I had this problem.. check the rubber seal , it's like a tube sometimes the tube is twisted or not round , just fix it with your hand , pull it back or something . good luck
