I checked each sensor. Everthing is okay. There is no fault but a right sensor thinks there is a obstacle. What can I do?

Swap the suspect one with another, if the incorrect detection moves, then its a faulty sensor, if it stays at the same position, then either the harness or the module.

Hello and thank you for your prompt reply. I already bought a new one and changed each one to the new. It stays. Is there a seperate module for PDC in a 2002 L322? Where is it?

Most likely the wiring harness for the sensors, well known failure point....  Pete
I now have permission from the boss to use Y.O.L.O. Enjoy life
