On certain vehicles produced from September 2002 - March 2003, equipped with 1.8L turbo, 2.8L V6, or 3.0L engines, a change in the electrical motor components in the fuel pump can lead to an inoperative fuel pump and, ultimately, stoppage of fuel supply to the engine causing it to stall.
Dealers will install new fuel pumps free of charge. The recall began on April 10, 2006. Owners may contact VW at 1-800-222-8987 or Audi at 1-800-822-2834.
