Super Fitness Health BlogAir suspension parts are revealed for Land Rover Range Rover Car!
The Range Rover has an air suspension. It does not use springs to keep the car level, but a series of air filled chambers upon which the car’s undercarriage sits. There are a few problems with this design, however. One of them is that the Range Rover’s suspension is governed by an ECU, and not a particularly bright one. The air filled chambers will deflate until the vehicle is sitting on the bump stops if the Range Rover parks on any ground which is not completely flat and level. If one tire is higher than another, that’s all it takes for the ECU to deflate the suspension in an attempt to compensate, thinking it’s a problem. This cannot be fixed except by going into the fuse box located in the dash of the driver’s side and removing fuse F17. This will incapacitate the ECU until you start the vehicle up and reinsert the fuse.
This is normal for the operation of a Range Rover, though it’s understandable that one could think it a trouble. If air goes from the storage tank to the chambers of the Range Rover suspension, on that point a drop in air pressure inside the tank. It passes through a valve block, where there is a pressure switch. The switch registers the drop in pressure from the tank and engages the compressor. The compressor should never be on for more than 6 minutes at a time, as this is how long it takes to fill a completely empty storage tank. If it does stay on longer than that, then there may be an air leak at the valve block. This is, regrettably, an extremely expensive car part to replace.
In cases where the Range Rover’s suspension has sunk to the bump stops, it would indeed take several minutes for the chambers to refill with air. If it takes a long time for the suspension to return to normal, even if the Range Rover hasn’t sunk to the bump stops, there’s an air leak. It could be in two places: the hoses running from the air tank to the valve block, or in the valve block itself. If the hoses are bad, this is a cheap and relatively easy problem to repair. A bad valve block is not.
