Air suspension. Another of the common Land Rover Discovery 4 problems is faulty air suspension. Originally launched as a more utilitarian version of the Range Rover in the 1980s, despite the luxuries, the Discovery line still has features that make it a suitable all-terrain vehicle.

It appears to me on the screen two minutes after starting up (only normal height is available) and the vehicle height and landing button turns off. I checked the air compressor and it is excellent. When the lift button is pressed, the car lifts quickly from behind and is slow in front. The self levelling suspension wakes up every so often and lowers the car to the lowest corner. One user reported "The front valve block was leaking air back into the system gallery which supplies air from the compressor and one of the front airbags had a small leak at the top. ". 6x4t1.
