VOLKSWAGEN IS RECALLING APPROXIMATELY 5,000 MY 2008 R32 (5TH GENERATION) VEHICLES. WHEN CERTAIN DRIVING CONDITIONS ARE ACCOMPANIED BY HIGH AMBIENT TEMPERATURES, THE FUEL TANK VENTILATION VALVE MAY NOT REMAIN FULLY CLOSED. IF THIS HAPPENS, LIQUID FUEL MAY ENTER THE FUEL TANK VENTING SYSTEM AND MIGRATE INTO THE EVAPORATIVE SYSTEM, SATURATING THE CARBON CANISTER. SHOULD THIS OCCUR WHILE DRIVING, THE VEHICLE MAY EXPERIENCE PERFORMANCE ISSUES (I.E., VEHICLE JERKING) AND THE MALFUNCTION INDICATOR LAMP (MIL) IN THE INSTRUMENT CLUSTER COULD ILLUMINATE. FUEL COULD LEAK FROM THE EVAPORATIVE SYSTEM LEAK DETECTION PUMP FILTER.
