I get brake pressure warning sometimes. But the brakes doesent bleed and the brake fluid tank is filled to the upperlevel. And i often get the message "oelst.lenkhilfe" on the display What is that?. The brakepedal goes down to the bottom but is good (it doesent go down to the bottom) when the engine is off, and the suspension feels soft but they feels much better to (when engine is off). Graetful of ideas.
