Distance warning after each braking process with a low final speed

Hello, I have a problem with our Tarraco eHybrid, which is not dramatic, but annoying. After each braking process, the distance sensors turn on beepingly and the corresponding graphic appears on the display of the infotainment. The front sensors are activated frequently, but not always. The whole happens without a vehicle in front or behind me. By pressing the button in the center console, the sensors of course stop again after the next braking. In the vehicle, the 360-degree camera and the factory-side AHK are installed (I only write because they have a “function coupling” to the sensors). I have already cleaned all the sensors meticulously, no improvement. The workshop can detect no error, there is nothing in the error memory (and only then it is allegedly paid by Seat). During the test drive, of course, everything was ok… Would be for a tip on what it might be or how the problem could be fixed. Thank you. I did not find an option in the menus/settings that I can relate to the problem. Thank you in advance! VG
