Hello together, a few days ago my car (BJ2002) VORNE is bagged on both sides. Ground clearance approx. 2 cm. Message: Stop, car too deep! I then tried to drive the car up via the switch. Didn’t work. I then disconnected the battery. Released. Message: Stop, car too low! Very slowly continued. Switch up again. At some point he was up again. Today: car still left above. Drive highway, message: level selection deleted. Then it didn’t last long. rt came the message: stop, car too low! (on the highway!!) I drove slowly until the next descent. When I was on the road I heard the first grinding noises. So stopped, looked. Car this time HINT both sides at the bottom. I then jammed the battery. Again started. Message: stop, car too low! Very slowly continued. Switch up. Somehow he was back up again. I then returned in a raised position about 30 km (only up to speed 80) I think the error always occurs when the vehicle level changes manually or automatically during the ride to the normal level. However, it surprised me that the error occurred once in front and once in the back. Car does not suffocate even with longer service life. I can normally go up and down in the stand. Driving up takes about 20 seconds. Does anyone have any idea what it might be about?
