Moreover, when you run the car while elevated other systems will be affected which are linked to the HCU, wheel speed sensors etc.. like ABS, SRS, traction control. But some systems will return to normal state once the car is put on the ground and driven for a short while since they begin to pick up the correct readings again. But unfortunately, some which has precautionally deactivated completely (you can notive the button, on the left side of the steering wheel, of the Heigth control not lit. this has to be reactivated by a diagnostic tool. And hopefully it will return to normal. It is better not to drive the car while the air cushions are deflated coz this might damage thw rubber. if this does not work (God forbid) then search for a level sensor which has bent or displaced. Good luck. Khaled
