I have attached the log file here. Unfortunately, I haven't been able to find the error. My initial suspicion was that the VTG linkage was not properly seated, or at least partially fixed. However, this can largely be ruled out. The movement is there, but I didn't have enough time today and will check it again tomorrow. The AGR is in order (verified via VCDS). The vacuum lines are also free of cracks or other damage. The N75 is also okay. The LMM is new.
Will an automatic system eventually fail under full load and run only in emergency mode? Turning off and restarting the ignition can temporarily resolve the issue until the next full load operation.
At approximately 2,500 RPM, the actual boost pressure value starts to deviate from the set value. At 4,000 RPM, the deviation is already 500 mbar.
It is absolutely necessary to state that the turbocharger was recently upgraded. Apparently, the previous one was "a disaster," as a colleague said, and someone from Bulgaria then installed a "new turbocharger," which has reportedly run for 3000km in four months without any problems until the problem started now.
Now, unfortunately, I don't know what is actually true.
Tomorrow, I plan to spend the evening and night reviewing the log file and would like to show it to you to get your feedback before I waste more time in the dark.
Best regards,
Rene
