Other Fuel System Hoses Lines/piping, And Fittings problems of the 2013 Volkswagen Passat

2013 Passat tdi sel. Emission modification at 28,514 miles. Now 29,200 miles on odometer. Bought the car less than a month ago. Vehicle is equipped with diesel misfueling guard. Stopped at grocery store and also filled up diesel from sam's club. Drove 4 miles down the road around 40 mph and about to enter highway when glow plug indicator started flashing and check engine light illuminated. Heard some rattling and the engine shut down without warning. Coasted over to shoulder. Would not start. Abandoned the car for the night. Next day I had the car towed to vw. They tested the fuel and it tested fine. Diagnosed as a failed high pressure fuel pump. It exploded and sent shrapnel through the fuel lines and forward into the engine and exhaust system. Also sent shrapnel backwards into fuel filter, fuel tank, and low pressure fuel pump. $5500-$7500 repair quoted if not under warranty.

The high pressure fuel pump (hpfp) failed while the vehicle was in motion (<10 mph) on a county road, causing the engine to stop, and disabling the vehicle on the side of the road. After being towed, an inspection by the vw dealer revealed that the hpfp failure sent mental pieces throughout the fuel system, including through the fuel filter, ultimately clogging the fuel injectors and rendering the car inoperable. The engine would crank but would not turn over. The dealer noted there was no evidence of gasoline contamination in the fuel tank. This failure occurred with ~1/4 tank of diesel fuel and no other indication of why the pump failed. No indicator lights illuminated on the dash before or after the failure. This failure is not covered under warranty and has resulted in a +$5,000 owner out-of-pocket cost to get the vehicle operational again. Vw has extended the warranty on the hpfp for the same vehicle make/mode for 2012 model year but this vehicle is a 2013 and thus not covered. This occurred on a 2013 vw Passat tdi with ~100,800 miles.
