Within the past six months or so, I've had a problem that has randomly occurred twice that I have not been able to find an explanation for. I have an 03 GTI 20th with 115k mi.
While cruising on the freeway (approx 70 mph), the car suddenly dies. The gas pedal suddenly does not work, the rpms fall down to zero, engine shuts off, red battery indicator light on instrument cluster turns on, power assisted steering doesnt work anymore, but all the electronics seem to work (radio, dashboard lights, etc are still lit up). After slowly pulling over to the side of the freeway, I am able to turn the ignition key to the off position and then start the car with no problems. So WEIRD!!
Reading the forums, some people suggest fuel pump or MAF sensor but no definitive solution.
A few months back, I took it to a shop to diagnose this issue with no results. They "inspected the electrical system" (which probably means they just checked to see if any CEL codes were thrown) and concluded everything was fine. I also took it to a dealer a few weeks back and they did a free "26 point" inspection and found nothing wrong with the car too.
Anybody have any insight into what this might be?
