ACC cannot be activated and “engine problem workshop” [VCDS]

Hello, at our Phaeton the radar had problems, the control unit was now repaired and should be initialized again in the vehicle. Unfortunately we can’t do it with the help of VCDS. We tried it after this instruction: However, the codes are accepted, but nothing changes. In addition, now it has been added that in the MFD stands “motor problem workshop”. How can this be removed? In a blog entry it was called code 30903, but this is not accepted. I attached the results of the car scan. Who can help?
