Finally got my S back to the dealer for the second airbag fault light, they are replacing the weight sensor in the passenger seat. In the last month the car started missing a shift between 4th-5th gear. Had to leave the car and bring home rental. They are supposed to bring my car to me when it is done(dealer is 240 miles away). Service manager said they are waiting for a call from Porsche on the trans, but he thinks it is the valve body. Last time they replaced the TCM. Anybody else have these recurring problems. The car only has 9,000 miles on it, I have had it since January. This is my 3rd trip to the dealer for problems.
