2.0 TDI Audi 8V: Sudden Power Loss Troubleshooting

Translated on 25-10-2026, 22:18.

You are my last hope: While accelerating, I revved the 2.0 TDI 150 HP engine in my Audi A3 to 3500 RPM - shifted gears: Suddenly! All power was gone. The engine was still running, but it had less than 0.5 horsepower. The workshop replaced the AGR unit and the AGR cooler, but without success. Now the car even stalls at idle. The timing has been checked: It's okay.
The engine is not making any unusual noises.
History of the last 30 days: Oil change and oil filter replacement, ignition key housing and beard replaced (broken while stuck in traffic on the highway).
Currently, the workshop has run out of ideas, and I suspect I won't be able to pick up the car in a working condition. Do you have any suggestions for me? I'm really willing to pay a reward for the right tip, as I'm truly at a loss.

Hello, is the turbo still working, or is it stuck?

Best regards,
