16408 Turbocharger unit jammed. Resolved. (Lösung)

Hello everyone,

The variable speed unit from the T6 110kW keeps getting stuck at 2500 RPM.
A new pressure converter for the turbocharger was installed, and it now works fully without going into limp mode.
It has lasted for almost 8 years and 315,000 km.

I'm still having a problem with the NOx sensors before and after the catalytic converter.
The MSG is not performing the initial calibration. When reading, it shows as inactive.
How can I calibrate them?

Regards,
Wolfgang
