Level shutdown when flat tires

Hello together. If on the AB back right a tire loses creeping air, shortly before the tire is flat the level shuts off. The vehicle notices something like that. It comes the message: error level workshop. The car then stands horizontally at the rear, takes away the damper on the other side air, so that it stands almost horizontally at the rear. Looks strange, because in front higher than the rear. Is that so normal? Has someone ever had a plate with the thickness, on the HA maybe? ignition off and again, message off, however, since then no more was driven, only on the ap tug up and just at the tyre dealer down again. Highlighting is the safety concept. I was driving exactly 200kmH before, Tempomat. Then the message appeared, however, I definitely did not notice anything extraordinary, except just this message. Nevertheless, I reduced to 80kmh, because of the safety of my occupants, and then I wanted to take the next exit, in order not to stand with my kids on a highway, if what is defective. About 30 seconds later I heard a slight noise from the rear right side of the photo, which is about 30km.
