have the following small problem.
I slowly drive over small hills with side slope, e.g.
(Hillow in a restricted zone), the red indication of the brake/hydraulic signal is reported with a signal tone.
Shortly after, the ad goes out again and everything is OK again.
Have already checked the brake fluid level and also the liquid level in hydraulic tanks. All right.
Where can the error message come from here, respectively? what is the cause of this ??
