I have the 2006 A-Class (W169). While driving an error message appered "ESP Faulty" together with other messages something like "Brake light falty" "Check lyre pressure and the car could only drive slowly. This happened a second time in a month or so. After stopping and starting after few minutes the problem disappeared. Both times prior to this we have hit a larger hole on the road so maybe this "disturbed" the sensors or someting like this. Someone else with a problem like this?
