Was told by Audi south orlando that a water valve seaped coolant through the connector up through the wiring and into the trans control module causing it to burn out causing a 14,000. 00 catastrophic failure.
On my car, there is an internal transmission coolant value that is part of the cooling system and obviously, that component also helps keep the transmission temperature in check. The issue with this defective part is the valve malfunctions causing coolant to penetrate the transmission control module and from there into the wiring harness. When this happens, it is a catastrophic malfunction of those components and a potential fire hazard. Water and electrical do not mix well. Pictures are attached. The root of my issue is that there is no way to detect that there is a problem with the automobile until this major malfunction happens. If that were not the case, the consumer could at least have the chance to have the car serviced preventing this huge expense and potential fire hazard. I have an email from the service manager admitting this is the case. In my case. The car ran fine. Then just went haywire. The service manager said coolant got into the control module and �fried� the module and wire harness. The pictures that are attached are from the same instance I found online and not pictures from my car. This is a very serious issue with this car. Audi has turned me down twice to fix this potentially combustible problem. Very scary.
My mil ( malfunction indicator lamp ) came on, in my Audi A6 2012 on 1/21/18. I made an appointment with my Audi dealership on 1/31/18. I was informed that my trans coolant valve was leaking into a wiring harness. They replaced my n509 valve and wiring connector. I found a technical service bulletin regarding this problem in my car as well as other Audi models. There was a recall for this in Audi a8 2010-2013. ( I have included these in the files that I have uploaded. ) the affected a8 vehicles have a coolant valve leak allowing coolant to enter the engine control module causing a loss of power or the engine to stall. A vehicle stall increases the risk of a crash. I had my car repaired as my wife drives this car and I certainly did not want the car to stall and possibly have a crash. It seems to me that the Audi A6 2012 should also be included in this recall. If any additional information is needed, please contact me.
Windshield wipers ceased to work creating dangerous situation. Dealer denied express warranty claim. Wiring on wipers was so flimsy as to apparently allow a mouse to chew through coating. Dealer charged over $640. To replace a $20 wire. Several e-mails and calls to Audi of America did not bring any action.
