Friday after Christmas, I did my 40k PM. Noticed some metal specks sitting on top of the fuel filter.
50 miles later glow plug light starts flashing and car goes into limp mode. Fortunately, I was less than 1/2 mile from my house, so I drove home and hooked up VCDS...

Figured the HPFP went, so I had the car towed to a dealership. They cleared the code, checked the strainer in the HPFP and found no metal. They test drove the car for 15 miles with a scanner attached to it, monitored fuel pressure and could not find a problem, so I got my car back. Two days later, I drive about 100 miles away from home, and it happens again. I stopped the car, shut if off for a couple of hours, then restarted it, and the flashing glow plug light was gone, no limp mode, and the car drove (85 miles) back to the dealership normally.
The code was still in the ECU memory, so they know it happened again. Now the dealership has had my car for over a week, and can't figure out what the problem is. They called the VWAG tech help center, and were told to drive it 10-15 miles a day, until they can re-create the problem while it is connected to their scanner.
Anyone else have a similar problem? My guess is that there is a faulty sensor, since the car drove normally over 100 miles in-between incidents, and then drove normally 85 miles after the second incident.
