As the result of an investigation into malfunctioning coolant valves, Volkswagen will be contacting the owners of certain 2010-2013 Audi A8 cars to return to their dealerships for repairs. According to the defect report, over time it is possible for coolant to leak through a coolant valve wire connection and migrate into the engine control module (ECM). The ECM could short and switch the engine into “limp home mode” or stall the engine completely. Drivers will be alerted of a problem through illuminated malfunction indicator and engine cooling system warning lights.
Dealers will replace the coolant valve and inspect the electrical connector for coolant penetration. The recall is expected to begin October. Owners wanting more information about the problem are asked to contact Audi customer service at 1-800-253-2834. The NHTSA campaign number for this recall is 16V-619.
