2002 Passat began thumping and lurching while in motion and while idling. Check engine light came on. Acceleration was abnormally slow. Three inches of standing water appeared in right rear footwell. Dealer informed me acceleration problem was due to water in tcm. Tcm short circuited and then powertrain dropped. Water damage was due to leaking pollen filter seal, which was subject to p9 recall. Car was past warranty on time, but not miles. They fixed pollen filter seal and told me they couldn't do anything about the $4,000-$5000 damage from the leaking water. The car is not safe to drive. My car is parked outside. We had several rainy days in the week before the problem. The service manager suggested I must have left the window open. I contacted vw corp and they suggested I take it to a dealer for repair at my own expense.
