I still have the issue. But I may have been a little too quick to say that my Passat was not recognizing that I had the brake pedal down. I was leaving my car in the garage and I dont drive it often, so when I do go start the car, I totally forget about the glowplugs needing a sec or two to warm up before the ECU will let the vehicle crank and start. So I would get in the car, mash the pedal down, forget about the glowplugs, push the start button, nothing happens, then I immediately press the start button again (not sure if that cancels the first start), nothing happens, then I chalk it up to, the car not recognizing the brake pedal is depressed.
But lately I've been experimenting, since Ive remembered about the glow plugs, and my car recognizes the brake pedal is depressed and the ECU allows it to crank and start. I will do more experimenting on estimating how far i have to push the pedal, but if i had to guess, i think the least amt. i had to push the pedal may have been about 1 inch.
