What owners say
While driving my 2012 audi a7 on the highway, received numerous error messages without warning on the dashboard. The car began to lurch, stall, and drive erratically with limited driving and braking control. Situation was very unsafe and potentially life threatening. Audi dealership stated that a coolant migration defect occurred. The coolant pump valve failed internally and leaked coolant onto the wiring harness. The coolant traveled along the harness and damaged or destroyed multiple electrical components including the ECM, transmission control unit, and the harness / electrical connections. Audi has a history of coolant pump defects and has active recalls for this exact issue for other models. This model, the 2012 a7 should be added to that list as it is a known issue and technical service bulletins were sent to the dealers.
Vehicle stalled while driving. Upon inspection by the dealership, I was informed that a coolant valve connected to the transmission control module had failed. This resulted in coolant leaking into the module and thereby damaging it. This is a known defect in a similar vehicle of the same year.

Check engine light came on so I took it to the dealership. Dealership told me that the "coolant valve leaked into the wiring harness and shorted the engine control module. May have cause an unexpected stall of the vehicle."
