This was pretty annoying. The car shut off one time while my wife was driving home in single digit temps. She walked home and I walked back and finally got it started. It didn’t happen again for almost a year. Thought it was a fluke. Then it began to give us trouble starting every now and then. The car had been tuned so the ECM had been opened and I thought it may have had water damage. I got a junkyard unit, and scheduled the dealer to replace it. We dropped it off and a couple days later they called me to say that it didn’t work, they couldn’t put the old one back in, and I would need a new ECM, new gauge cluster, and some other immobilizer module to the tune of $3300.
I said forget that, and rented a UHaul car hauler and collected it from the dealer. I have a VW technician friend who fixed all of that with a laptop and no new parts. Unfortunately after all that it was not the solution. We diagnosed it as a fueling issue, but since it was intermittent we replaced the in-tank low-pressure fuel pump, the high pressure pump (borrowed from a known good car, we didn’t buy this pump) and the problem persisted. Finally our only option was the fuel pump control module. Replaced it and held our breath. Finally we got it. No problems since in about 15,000 miles.
