I was having an issue with my 2013 Audi A5 starting. A call to roadside assistance was able to jump my battery and the car would start and run. However, the same issue kept happening. The EPC warning light would come on and it took a few weeks to get scheduled with a mechanic. I purchased a mobile jump starter myself because I never knew when the car would or wouldn't start. After taking the car to Audi, they found the "transmission coolant valve failing internally causing coolant to migrate up connector - this is causing a short which is draining the battery. If not fixed it will continue to deplete the batter. Recommend replacing valve and and connector". [2023 Audi Inspection Report.pdf] This was verified by another mechanic who did the work and shared the faulty, corroded transmission pump connector and leaking valve. [photo: 2023 Corroded connector Transmission Coolant Valve.jpg; 2023 Transmission Coolant Valuve and connector.jpg] I won't speculate about the potential outcomes of such a failure, but I was told by my mechanic before I brought it in that I should no longer jump the car, because if what Audi found was correct, I could at minimum cause a full failure of the car's electrical system or a fire could start and recommended that I tow the car in for repair, which is what I did. An internet search shows this isn't a unique or isolated issue. Audi owners over the past 7+ years have been experiencing the same issue with the transmission coolant seeping into electrical components, causing shorts and electrical problems like mine. [XXX] [XXX] [XXX] This pump and its proximity to electrical components is a dangerous risk to drivers not aware that what appears as a simple dead battery, could in fact be one jump start away from disaster.
