TDI Engine Problems: Intermittent Power Loss

Hello,

Perhaps someone has encountered this problem before.
Occasionally, roughly once a week, my Audi TDI with 110 horsepower and the AFN engine...
No power, as if the turbo is missing.
After turning off the engine and then restarting it, the engine runs normally again.
There are no errors stored in the error memory.
I'm ruling out LMM (Large Language Model) because the error only occurs very rarely.
Could it be related to the magnetic valve for boost pressure limitation? I don't want to buy it right now without being completely sure. Has anyone else experienced this issue before?

Hi TDI-Sepp,

As always: you can't give a general answer, so please log the MWB 3/8/11 if the error is currently occurring!

no power, it's like the turbo is missing.
After turning off the engine and then starting it again, the engine runs normally again.

Immediately after that, read the memory. It's a sporadic error that is cleared after a certain number of startup cycles. Search the documentation related to 00575. Something like that will be in there. }

I had the same problem with my Mazda6.
Ultimately, the problem was with the boost pressure control valve. I took it apart, cleaned it, and replaced the seals. It's been running without any problems since then.
Also, since recently, the performance is slightly reduced when the engine is cold, but this disappears immediately after a few kilometers. I never noticed this before.
