ASZ performance loss

Hello,

I'm experiencing a noticeable loss of power in my Golf 4 TDI with the ASZ engine, 96 kW, and 180,000 km on the odometer.

I've uploaded a log file; hopefully you can make sense of it. Otherwise, I will definitely create the requested log files again (I don't really know much about this).

Regards,

PS: The LMM is still from 01, so it's the first generation. Should we just replace it?

I don't know why, but the N75 models seem to be particularly popular at the ASZ (presumably a repair or service center).
Have you tested it yet?
For testing purposes, you can also try swapping it with the solenoid valve from the EGR system.

hi,

I once did a test where the VTG rod moves, and it actually slides back and forth smoothly. This would suggest that the N75 valve is working, right?


Hello.

If that's the case, then the N75 valve and the VTG (variable turbine geometry) should be functioning correctly.

LMM would then be the next candidate.

If this is only the first one, then I would suspect it even without a log file.
What amount of air is displayed as being drawn in at idle?

So, the LMM is still the first .

Can you identify anything related to KMM in the log?
