Wiring Problems of Audi A7

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.

I was told today that the airbag light which would not go out is because of a problem with the wiring harness (which even the dealership thinks is a manufacturing problem though I do not know if they told that to Audi) to fix this, and assure that my airbag will deploy, they want over 18 thousand dollars. Audi has disclaimed any liability for this issue and my extended warranty won't cover it because its an airbag issue.

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. ".
