On certain Passat and Passat Four Motion vehicles equipped with an automatic transmission, an underbody heat shield may become damaged. If this occurs, the heat shield may contact the exhaust system, which can result in a vehicle fire. In addition, the affected vehicles may have a fuel line (1.8T engine only) or fuel tank ventilation valve (4motion / all-wheel drive vehicles only) that may leak due to fracture. Fuel leakage in the presence of an ignition source can result in a vehicle fire. Correction: Dealers will affect repairs.
