Electronic air suspension (EAS) parts for Discovery, Range Rover and Range Rover Sport: compressors, air springs, valve blocks and height sensors.
Air suspension is fitted to most, but not all, Discovery 4 vehicles. Drivetrain and suspension: Permanent four-wheel drive with a two-speed transfer case (from 2014 some markets could have a single-speed unit instead), Terrain Response and all-round height-adjustable air suspension on most vehicles. Check which system your vehicle has before ordering, because a steel-sprung vehicle needs conventional suspension parts instead.
See Discovery 4 suspension for that side of the system.
The cars.co.za Discovery 4 buyer's guide names air suspension and handbrake issues among the model's known problems. Air suspension warnings usually trace to compressors, valve blocks, air springs or height sensors.
Parts commonly needed on the Discovery 4 include air suspension components (compressors, air springs, valve blocks, height sensors), timing belt kits for the 3.0 diesel, intake manifolds, EGR valves, turbochargers and mass air flow sensors.
Air leaks are the root of most failures. A leak from an air spring, air line or valve block makes the compressor run much more than it should, until the compressor wears out or overheats. When a compressor fails, find and fix the leak as well, or the new compressor will go the same way.
A corner that sinks while parked usually has a leak in its air spring, air line or the valve block. If the whole vehicle drops evenly, the valve block or a common line is more likely. Spraying soapy water on the springs and fittings with the vehicle raised can reveal where the leak is.
For how these parts work and the signs of wear, read the Land Rover air suspension guide.
