2013 Audi A3: engine stalls while driving

Filed May 13, 2022 · Transmission · MD

Car stalled in fast moving traffic, and then lurched forward. In the stall the car behind me almost ran into me. In the lurch, I almost rear ended someone. Fortunate that both times there was no collision. Took the vehicle to Audi and the car has been diagnosed with failed mechatronic - a $4,000 repair. It was shared that this is a known issue with Audi for my model year (faulty mechatronic), and as such has been recalled in several countries, but not the US. I called Audi USA and was informed that yes it is a known issue and has been recalled in other countries, but that the federal safety agency has not required Audi USA to open a recall here, and so they can't help me. I'm asking for some assistance. Thank you very much

2013 audi a3 tdi., serviced for 65k maintenance 10/31/15. Next day , the car began abruptly loosing forward momentum under acceleration, and died in an intersection. Towed to audi, and they told me it was bad diesel. They flushed the diesel and replaced the fuel pump. (kroger denied my bad diesel claim.) on 11/2/15, the check engine light came on, same issues. Dealer told me it was the engine speed sensor and replaced it. One month later, 11/6/15, my check engine light came on again, with the glow plug light flashing. This time the dealer said it is was throttle sensor fault. They had to order the part, and told me it was 'safe to drive'. In the time between, I would regularly experience the loss of forward momentum while accelerating up hills. I had the work done 1/7/16. 9 days later after the throttle sensor replacement, saturday, 1/16/16, while I was driving, the car began unexpectedly losing acceleration in an extreme fashion, and stalled out twice within a 15 minute drive. It had been suddenly and briefly losing acceleration when accelerating while going uphill for several days. It also stalled out while accelerating into an intersection (extremely dangerous) and while parking. I had an error # p2101, and it would not accelerate past 40 MPH while going uphill until I stopped and restarted the car. On 1/18 (monday) I took my car into audi service. They have had it until now, 2/9/16, and have replaced the entire computer, and it has not fixed the issue. They were able to replicate the issue, but have not been able to find a solution. They now say that they recommend replacing the engine wiring harness. This is a concerning safety issue, given the abrupt drop in acceleration going uphill, the loss of acceleration and the multiple stalls while driving.

While at a complete stop at a red light, I felt what I can only describe as a "clunk" and the battery light on my dashboard illuminated. The car had stalled, and I had to restart the car entirely in order to continue on my way.

While driving in seattle's notorious stop and go traffic, my a3 tdi, has stalled. It acts as if I have "dropped" the clutch, which is impossible being an automatic!!. This has happened to me on two occasions. There is less than 5k miles on my new car. Both time it has gone immediately into university audi. First time, no answers. Still waiting on diagnostics from today's episodes.

After driving on the highway for about 18 miles, took an exit and stopped at a traffic light. When the light changed to green I entered the intersection and the engine stalled without any indication of a problem. I was able to start the engine right away.
