Open the full vehicle complaint log (all categories)ECU starting to malfunction as a coolant leak valve is leaking into it. There is a recall for these models but not for my specific car but I do believe my car is affected because my car has a coolant leak that I personally can’t find and my car was just worked on by Audi Indianapolis and they did not see any coolant leaks either. It was mentioned to me by another Audi A8 owner and it’s making sense to me as the way everything began to fail on my car until I detached the battery and attached it back it worked fine but sometimes the ECU will begin to fail for Adaptive Cruise Control randomly, then it will work again. These are symptoms of coolant leaking and affecting the ECU, and I can’t afford to pay for that to be fixed because it would cost more than what the car is worth but I would like to see if my car was affected by this recall because i genuinely believe this is what is happening
