Few months ago, the sunroof on my ‘14 C2S stopped working. Still under warranty and took her in. Dealer replaced motor and all was good. Then while driving heard a clicking sound that wasnt there before. hummm. The cabin in the P isnt the quietest, thats a given. But, this is a new noise and couldn’t isolate it. Took it in and they had a tech ride along with me. He held his smart phone up near the sunroof and recorded the noise. I. left the car in for a day for a fix. They removed all the sealng associated with the sunroof and said they added some felt material in areas they felt where it was needed. Except for normal road noise she is as quite as a church mouse in there now. i think its quieter than when it was new. Great dealer experience. Porsche Marin.
