No, no fault codes at all.

Any further ideas what to investigate? Could blocked EGR cause this kind of behavior? How about calibration issues with parking brake (if previous owner has changed the parking brake pads but didn't complete the braking in sequence)...?

I would try a throttle body reset - if it works correctly with the cruise control engaged, could be a calibration issue with throttle position sensor - at least that’s what I would try next...

Do you have some recommendation if the automatic transmission adaptations should be reset at the same time again as the throttle body adaptations will be reset?

Does the throttle body reset contain some risks to mess up something?

Btw, does anyone have the instructions for transmission adaptation calibration drive after reset?
