Hello I have a problem with my adaptive cruise control, which actually works very well, but as soon as the temperatures rise the system fails with the message Radar disturbed see manual.The housing of the radar in the radiator grille I cleaned there is nothing on it that could disturb.The system then drops out incl. tempomat from temperatures of 23 degrees constantly, which is very annoying.Has anyone ever had such a problem?The friendly could not help me any further until now.
