I just picked up my 2001 jet wagon after cv boot replacement. The driver's front seat would not lock and slid back and forth in response to my driving. I thought it was a temperature related problem (car was left outside in 0 degree weather by dealer). I garaged the car overnight, letting it warm up. It now will lock in the farthest rear position. I, too, am looking for the solution and suspect this mechanism is over-engineered and the failure to lock is the result of an electrical failure.

Tried wd4 on the track and cable. Worked it back and forth also side to side and was able to get it to lock in position (for now).

Great solution. I did the same thing after sending my last comment, not as complicated as I first thought. Everything seems to work well now. Odd that these things seem to go bad at the same time. I also have the common problem that most others have with the mysterious unattached spring. My local service rep stated that it was a problem with a broken tab on the seat and repairs would run into $700. At least this problem was solved, for the time being, at no cost.

Glad it worked for you too. Happy to pass on a tip that helps us all save money!

Thanks for the tip. Wd40 did the job for my 2000 jetta. Had to oil the rails and both ends of the cable mechanism that makes the seat lock and unlock.
