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

While driving on a city street my car suddenly stopped (4 lane street -- 2 going, to coming). There was very heavy traffic and I could not move the car as it would not come back on, nor could I shift the car into neutral to push it out of the way. As a result, the car remained in the middle of the road, in heavy traffic, for about 2 hours until the tow truck arrived. The car was towed to the local dealer where it the dealter took 4 days to diagnose it with having coolant leaked into the engine wire harness and into...

the pcm where it shorted the pins. As a result the car was completely inoperable. This caused a very unsafe condition as the behind me suddenly had to break and just missed hitting my car. The car just shut down and would not restart or engage the neutral gear in order for me to get out of the middle of the road. This seems to be a common thing and something that should require audi to address via a recall in order to replace the affected part(s) before something like this happens or require audi to make appropriate repairs to those affected by this common and dangerous fault. This is a serious safety issue! Dealer wants $11000 to repair it! What should I do?? Loss of work and pay as car is stranded at audi dealer! Agony! Embarrassment!

The transmission coolant valve leaked coolant on to the engine control module causing it to malfunction. The card stopped while in motion in the middle of the busy street and I was almost hit buy a semi truck. It started back up, I got it to a parking lot and it stopped again. I have found no less than 50 online complaints about this problem. Most of the complaints state that the manufacturer was "aware" of the problem.
