Fuel system, gasoline:deliveryApr 7, 2008 · NHTSA campaign 08V156000 · 412,000 vehicles

Problem: Volkswagen is recalling 412,000 my 1999-2005 passat (5th generation) vehicles equipped with automatic transmissions and produced after june 14, 1999. These vehicles may have an underbody heat shield that can become damaged. In addition, affected vehicles with automatic or manual transmissions may have a fuel line (1.8t engines only) or fuel tank ventilation valve (4motion/all wheel drive only) that can leak due to fracture.

Risk: A heat shield that may contact the exhaust system can result in a vehicle fire. In addition, a fuel leak from a fuel line or fuel tank ventilation valve, in the presence of an ignition source, can lead to a vehicle fire.

Fix: Dealers will install additional underbody heat shields on vehicles with automatic transmissions to cover the possibly damaged areas and flash all 1.8t engines with a precautionary software update. Dealers will also inspect and adjust the fuel line routing on 1.8t vehicles and the fuel tank ventilation valve on 4motion/all wheel drive vehicles, and replace components if necessary free of charge. The recall began on june 13, 2008. Owners may contact volkswagen at 1-800-822-8987.

Problem: On certain passenger, wagon, and convertible vehicles equipped with or without cruise control, a brake light switch may malfunction if it was installed incorrectly.

Risk: The brake lights could become inoperative, or remain on. Failure to provide the proper signal when braking could lead to a crash without warning.

Fix: Dealers will install the newly designed brake light switch free of charge. The recall began on april 27, 2007, and will be conducted in several staggered mailings through september 21, 2007. Vehicles within the make, model, and model year of this population may be involved in either this recall or 06v-183, but not both. The remedy is the same for each recall.
