I took my vehicle to repair for 2 recalls on 2/22/21, the next day 2/23/21 they called me telling me that I have to pay $ $550 for the repair. According to downtown Audi tech the ECU of my vehicle is defective because they cannot communicate with the vehicle's computer, before taking the vehicle to repair the recalls it was in good condition since I changed the oil and connected my scanner to reset the maintenance message on the vehicle dashboard. This is absurd that they want to scam their customers. Now they want to give me the vehicle without repairing the recalls and with lights on on the dashboard of my vehicle, this is not ethical or professional.
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 catastrophic failure.
Ran obd reader myself and at mechanic and found the following; P0456 evap emission control system (very small leak) | leak detected and P190F00 coolant pump for charge pressure cooler | electrical malfunction in load circuit. Mechanic informed that the vehicle needs a software update regarding the P0456 code as no leak was found. Also that only Audi performs this update. Regarding the P190F00 code informed me that there are several recalls regarding this issue as it has been causing some severe symptoms such as engine shaking, loss of power, squealing, whining noise near or at timing belt area at start up, delayed reaction at acceleration ( takes a while to reach desired speeds), temp gauge lowering despite warm up, warming of vehicle taking longer, unable to drive over 30-40mph and RPM won't go above 2000-2500 rpms. Acceleration is not as responsive as it should be.
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.
The contact owns a 2012 Audi A6. Whenever an occupant was seated in the passenger seat, the air bag warning indicator illuminated and the air bag off indicator below the radio flashed. The failure occurred for approximately three months. The vehicle was taken to the Audi grapevine dealer (1260 E state hwy 114, grapevine, tx 76051) where it was diagnosed that the pod system needed replacement. The manufacturer was notified of the failure and opened case number: 180078683. The vehicle was not repaired. The approximate failure mileage was 82,000.
While driving on a Sunday, the car reported transmission issues but it stated we could continue driving. The following day, there were multiple systems failure warnings. This occurred at 54,000 miles and 49 months since purchase. The car began to lose power but was driven back to the dealership. After a lengthy period of time, the service manager reported that "coolant leak in valve N82, coolant migrated into harness and contaminated transmission control unit, causing no comm in pwrtrain can; tsb2033806/7." this repair required replacement of major components and extensive labor costs. The total cost was $9606 and the dealer/Audi voluntarily paid $5391 of the costs
O-ring failure in 2012 A6 3.0 caused the transmission to internally leak fluid causing the electonic system to go bad. All of the following lights came on when issue started. Check engine light, gearbox, mil trac control, mil epc, light airbag mil hi-speed cooling fan mil tire pressure warning light the transmission would not shift, major lack of power to engine. Parking brake would also activate by itself. Instrument panel light up like a X-mas, when I pulled over the car shut off and would not turn back on.

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.
