How often does the 2019 Audi A6 fail its MOT?
Why they failed: the share of failed tests with at least one fault in each area (a test can fail on several). Cars first registered in 2019, tested in Great Britain in 2023; first registration is usually, but not always, the model year. Source: DVSA anonymised MOT tests and results, Open Government Licence v3.0.
What do 2019 Audi A6 owners report?
12 of the 114 complaints, the most recent for the most-reported components, as the owners wrote them. NHTSA removes names and VINs; long reports are trimmed. CarHooq has not verified individual claims.
The factory-installed mechanical water pump module suffered a severe internal seal and housing failure. This allowed pressurized engine coolant to migrate directly into the engine's vacuum control system and vacuum lines, damaging crucial emissions and vacuum tubing. This defect poses a severe safety risk as coolant entering the vacuum grid can cause sudden loss of engine power, erratic braking assist, and localized engine overheating while operating the vehicle at highway speeds.
My 2019 Audi A6 was diagnosed with catastrophic internal engine failure on May 9, 2026 at Audi of Newton, Newton, NJ, at 93,645 miles. The vehicle required a full engine rebuild performed by REV Auto NJ at a cost of $12,000. The failure involved metal debris found in the engine oil, consistent with the documented EA839 3.0L V6 TFSI rocker arm needle bearing failure or piston skirt failure affecting this engine family. The EA839 engine used in this vehicle has a documented history of design defects: (1) Rocker arm needle bearings in early production engines were undersized and prone to…
The central locking / electronic door lock system on my 2019 Audi A6 intermittently malfunctions, sometimes with a long beep sound and an error message appearing on the screen in front of my steering wheel. The affected system is available for inspection upon request. The issue does not happen all the time, but the door sometimes fails to unlock or appears to re-lock while I am trying to open it. In late April 2026, in the morning, I was leaving YogaSource in [XXX] . As I approached my vehicle in the parking lot, an unstable individual was approaching the area near my car. I attempted to enter…
Shortly after purchasing in 2025 I began having occasional issues with the door locks. Eventually the issue would self resolve but now I have experienced at least 2 times in last month being locked inside the vehicle and unable to exit without climbing into the passenger seat. I have not taken it in for repairs yet due to cost concerns but I am worried about this dangerous situation.
Complete shut down of all electrical associated components while driving on highway Loss of power steering loss of braking loss of ability to accelerate transmission failure loss of lane detection, loss of car detection. Diagnosed as , faulty alternator recall repaired and continuation of same electrical failures despite six additional repairs Multiple failures of all electrical components on highway road and side roads
Yellow battery indicator light came on while driving car in 35 degree weather after a week of sitting in garage (holidays). I pulled over, read the manual and it said this could cause battery light to illuminate. I called the dealership service to ask them, they said possible reason. I decided to drive across city to dealership, 25 minutes away. On HOV lane, red warning lights flashing to pull over then 5 seconds later everything went black. No electrical, no engine, car died. VERY DANGEROUS!! Read later that this has been happening on Audi A6 (& other models) for 2+ years. Towed to dealership…
Side marker light in headlight stopped working
After heavy down pour, the car was driven while the streets were still very wet. The car was driven through a 2 - 3 inch puddle of water that lasted less than 1 second, which caused a splash to the passenger side of the car, (the middle of the street did not have an accumulation of water) and within 30 secs caused the power steering warning light came on. This was not a flooded street, just the normal accumulation of water on the side of a residential curbed street. The steering immediately started to stiffen up and required increased effort to turn the steering wheel. The first warning lamp…
Electrical malfunction warning. Steering wheel got tight. Transmission failure warning. Then the the car began to stop. all types of various warnings were popping up on the heads up display. It is in the process of getting taken to the nearest dealer.
When backing up the car the cameras don't turn on and often times the collision sensors go off randomly. On the highway the emergency brakes go off randomly when a car passes by on the right-hand side of the vehicle.
Car flashed several warning signs, electrical system malfunction, steering malfunction, lane assist malfunction, and finally powertrain system malfunction where car was barely driveable at very slow speed, died and I luckily was able to pull over and coast into a parking spot.
The car gave me electrical malfunction warning while driving on the highway, then all the screens turned black, and the car completely shut down while driving. The steering was still working, although heavier than usual, and the breaking also worked. The car slow down to a complete stop at the shoulder of the highway. This was very concerning, and thankfully happened close on exit with a shoulder at the side in which I was able to park the car.
