Was driving my 2010 vw Jetta sportwagon tdi at approx. 55 miles per hour when my service engine light came on and glow plugs started flashing. Car began to buck as if not getting any fuel through the system. Car stalled out on highway within a minute of the service lights flashing and will not restart. Luckily the cars behind me barely avoided hitting me as there was zero warning. Had to be towed to my garage, expect diagnosis tomorrow but after reading up on other complaints I am pretty sure they will report back that it is a hpfp issue and the system will need replaced.

Vehicle had a sudden loss of power (misfiring very badly) and would not maintain speed. The service engine light never came on, and there were no trouble codes stored. Vehicle was brought into vw dealership for diagnosis and they confirmed the camshaft was completely worn and "several lifters had caved in. " internet searches confirm this model vehicle (tdi with a brm engine) has a known history of camshaft failure. Aside from the cost of replacement ($2900 at the dealer), this could have caused a potentially life threatening crash.

High pitched whine, sudden stall at hwy speed. The fuel light and service engine now light came on. The vehicle would not run and required a tow to the dealership. I was notified it would be a $5000+ repair and the hpfp failed requiring the entire fuel system to be replaced.
