The folks on the TDI Club have been tracking and reporting a problem with the "High Pressure Fuel Pumps" on A6 VW TDI models. According to an article in the Detroit News and a Left Lane News blog post, the National Traffic Safty Administration has now launch an official investigation.

According to posts on the TDIClub forum, owners suffering damage from a HPFP failure have expensive repair costs nearing $10,000. Hopefully VW will positively address this for current and potential TDI owners.

The agency is looking into 37,889 2009 Volkswagen Jetta TDI models after getting seven complaints on that model and year "alleging that while driving and without warning the engine limped and then stalled almost immediately."
