After driving for approximately 250 miles on the Interstate the engine on my car wrould not turn off when pushing e start/stop button. I had to pull a fuse under the hood to stall the engine and then disconnect the battery to shut down all the fans and lights after parking in my garage. Now the dash lights say to put the gear selector in park when I sit in car with battery reconnected and the gear selector is in park. I can't move the selector our of the park position?
After the fact, I found a fuse box diagram for the VW Passat on Start My Car. After getting the engine to shutdown by pulling all the 40 amp fuses that I could find in the engine bay and disconnecting the battery overnight, I couldn't get the system to power up the next day. The information display kept saying to put the gearshift in the park position (It was locked in the park position at the time!) I tried the capacitor discharge drain technique with the negative battery cable disconnected and using a jumper wire between the negative cable end and the positive battery terminal for 30 minutes and then manually unlocking the gearshift per the owners manual. The next day it started up after connecting the negative battery cable and except for getting error messages about the ACC being inoperative and the clock and trip odometer resetting to 0, everything worked. I even took it into the VW dealership that sold the car to me when new and where it has had 99% of services and repairs done over the past 7 years and they couldn't reproduce the problem. My confidence in VW is wearing thin and I'm not sure how much longer I will keep driving it.
