Volkswagen is recalling the 2010-2013 Audi A8 sedan to address a problem that could cause the vehicle to stall in traffic. More than 9,000 vehicles in the U.S. are affected.
The recall stems from a dodgy valve in the coolant system that was manufactured by Austria's MSG-Mechatronic Systems. According to the National Highway Traffic Safety Administration, a lack of sealant on that valve could allow coolant to leak into the engine control module.
If that happens, the effects could be severe. A short circuit in the control module could force the vehicle into "limp home" mode, resulting in a reduction in power. In some cases, the short could even cause the vehicle to stall. Depending on where that happens, it could dramatically increase the risk of a crash.
The good news is that drivers may be alerted to problems by two lights on the instrument cluster: the Malfunction Indicator light and/or the engine cooling system warning light.
The recall includes 2010-2013 Audi A8 vehicles built between May 15, 2010 and May 14, 2012. NHTSA says that a total of 9,102 U.S. vehicles are affected.
Audi will begin mailing recall notices to owners on October 19, instructing them to take their vehicles to dealerships for service. Dealers will replace the suspect coolant valve and inspect the car for any signs of associated coolant leakage.
If you own one of these vehicles and have further questions, you're encouraged to contact Audi customer service at 1-800-253-2834. Alternately, you can call NHTSA's Vehicle Safety Hotline at 1-888-327-4236 and ask about safety campaign #16V619000.
