Just a week ago I encountered a problem I haven't seen mentioned on the board. I was going to meet my wife for dinner, and about a block away from the restaurant there was a loud CLUNK as I shifted from first to second. As I let the clutch up, the car behaved as if it were in neutral. I depressed the clutch again and found that the shift pattern was gone. I could move the shift lever easily fore and aft, but there was no movement possible from left to right. With some experimentation I was able to find a high forward gear, could have been third or fourth, and feather the clutch to pull into the restaurant parking lot. The car was towed to the dealer the next morning. It turns out the problem was a broken shift cable. I got the car back last night, and it's fine. The dealer even washed the car and vacuumed the interior.
I'm very fortunate. The car is under warranty until next April 29. It's supposed to snow here in Minneapolis tomorrow, and I'll be parking the car until April, I would guess. We drove the car as far north as the Canadian border in September with the local Porsche club. Good thing it didn't break then.
