Fuel Pump Failures Under Scrutiny
Volkswagen and Audi TDIs are under investigation for fuel pump failures. The NHTSA opened the investigation in February 2011 on the 2009 and 2010 Golf and Jetta models. The issues seem to center around contaminated fuel and the high pressure fuel pump not being capable of dealing with diesel that’s been contaminated by gasoline either by the customer or the fueling station.
