Wastegate actuator for turbocharger stuck. Solved (Solution)

Hello everyone,
The throttle body on the T6 110kW engine is increasingly prone to sticking at 2500 RPM.
I installed a new pressure transducer for the TL system, and now it can reach its full range without going into emergency mode.
It lasted almost 8 years and 315,000 kilometers.
I'm still having a problem with the NOx sensors before and after the catalytic converter.
Pairing is not performed by the MSG. "The reading shows as inactive."
How can she be trained?
Best regards, Wolfgang.
