You have a short circuit between the backup light switch and ground. VWs are infamous for this because the power for the backup lights comes off the side of the ignition coil. When you stick the car in reverse, it grounds the coil and the engine dies.
probably..... NOT!!!!!!!!!
car cuts off
the neatrul switch
The car might have an automatic cut off to either disengage the transmission or cut off the engine. Otherwise you will rip apart the transmission.
my experiencess with vehicles that cut out while idleing would be a fuel filter or fuel pump problem.
Cut it off
Check the wires on the coil. If a couple are swapped to wrong positions, the car will run, but immediately stall when put in reverse.
Both a stuck reverse switch and shorted wiring can be causes for reverse lights to stay on. Under normal circumstances, the reverse lights turn off as soon as the vehicle is shifted out of reverse.
If you mean the car stumbles and dies then you need a tune up. If you mean the car dies "instantly" the Reverse light wire might be interfering with the carburetor shut off solenoid. The Solenoid is also wired to the coil with the reverse light. You should be able to hear a "click" on the carb when you turn the key on and off. With the key on, have some one put the car in reverse and see if you can hear the solenoid click off. Jay, you're really close but not quite. The problem is the reverse-light circuit's shorting to the frame. Maybe one of the wires has the insulation rubbed off and it's touching the frame. When you put the car in reverse, the switch closes, the power from the coil goes to ground and the car dies. The root cause is Volkswagen is running WAY too many things off the side of the coil.
Check tranny fluid!
when your in a manual and you have the car in first gear with the clutch all out the wheels cannot move and so the engine cannot work or it will break so the car stalls and the engine turns off
Yes it does cut your car off, The sensor is controlled by module that controls everything
