Audi A6 won't shift problems

Filed Jun 15, 2026 · Acceleration, Electrical · LA

The car throw a EPC warning light which cause the car to go n limp mode. With doing research ot has to do with the transmission. This cause the car to drive sluggish unable to reverse at times unable to take the car out of park at times. It also cause the car to randomly shut off when reversing or at times when im sitting at a light n i begin to drive the car can randomly shut off at times. Which in my open is unsafe because what if the the person behind me isnt payimg attention and i get rear ended. Ive reached out to Audi dearlership is was told a part was discontiued and to bring it in for them to further diagnostic it. Ive had the codes read and im getting the symptoms of the code i pulled but told that part was discontiued. So i feel like if thats the case Audi should have did a recall on the car.

Electrical fault dash warnings (steering, transmission, braking and many other things too numerous to mention came on while driving the car and it went into limp mode and forced the car to stop and would not restart. The car had to be towed to the dealership where they diagnosed the problem to be the "alternator" which is more accurately what is known as the "belt starter generator" BSG. The BSG runs the start stop feature of the car and charges the mild hybrid 48v battery system that runs many of the critical features of the vehicle. They do not have the part in stock and do not know how long it will take to get in. I understand that there is NOT an upgraded part available that will fix this issue, only the same part that they are continuing to put on all of the V6 engine models since 2019 to today. The A6,7 and A8 and Q5,7 and Q8 models in particular are being affected. This is an extremely dangerous problem that has not been remedied by Audi/VW to this point and the federal safety agency should issue a recall.

The Alternator had failed along with the battery and shut off the car, rendering it useless on the road. The vehicle is still under the New Car Warranty. It was a hazard as it could not be put into neutral and was stuck in park. The dealer had confirmed it was a manufacturer-wide problem with waits of up to 3-6 months for the part. The tow truck had difficulty towing it up as the car was not able to roll. Before the car shut off immediately it had given the warning "Electrical System: Malfunction! Please Contact Service, as well as Auto Start Stop System: Malfunction!".

Two miles from home all sorts of electrical malfunction warning ⚠️ lights appear. Too many to list here. Then car completely stops and all electricals shut down. This happened in the middle of a very busy three lane 45mph main artery. Stuck in gear, unable to push off side of road. After ten minutes or so of cars zooming around us, it started enough to get off road to safe place. Waited 4 hours in freezing cold for tow truck. Very scary incident for my wife and me, as we are in our 70s. Towed to my local Audi dealer. The problem seems to be with the “Starter Alternator” and is a national problem with 1000s of affected owners. Was told 29 vehicles are ahead of mine for replacement and that it could be weeks before parts are available. One car family and no loaners available and there talking weeks / months to repair.

I researched similar complaints and found that the federal safety agency id's 10555091 and 10444769 describe the exact same issue I recently experienced. I put the key in the car to start it and the it would not even turn over. The dash lights come on, the radio works, however the car is stuck in park and all wheels are locked. Car had to have dollies put under each wheel in order to roll it up onto a tow truck. Mechanic diagnosed the issue to be a failed computer module on the steering column, which cannot be removed and replaced by itself. The whole steering column had to be replaced. There are so many forums out there describing this same exact issue. This must be investigated and taken care of. I don't mind paying for car repairs, however, when there is a pattern of unusual and extremely costly repairs, the manufacturer needs to be held responsible.
