Hi, for a few days I hear a short sum in my Omega B Caravan 2.5 TD after the start, which shuts down again after approx. 2-3 seconds. At the same time I noticed that the rear has increased by a few millimeters every day, so that the car now comes quite high legged. Consequently I realized that the level control now every day assumes that the car would be heavy loaded (but is empty) and wants to balance the level accordingly… Had Any of you already found the same problem and a solution without having to go to the workshop?
