Hello everyone, I've found the error. It was a faulty ABS sensor at the rear. I re-examined the data blocks and noticed that one sensor at the rear was providing a lower signal than the others, but only up to about 8 km/h, then it showed normal values again. The cause: Once, a wheel nut was over-tightened at the rear, which slightly bent the sensor, so that the air gap between the sensor and the toothed disc was no longer correct.
But NO error was stored in the control unit!
New sensor installed, and everything was fine again.
Maybe I could help someone with the same problem.
Best regards,
