Defender (L663) air suspension
Electronic air suspension (EAS) parts for Discovery, Range Rover and Range Rover Sport: compressors, air springs, valve blocks and height sensors.
What is specific to the Defender (L663)
Air suspension is fitted to most, but not all, Defender (L663) vehicles. Drivetrain and suspension: Permanent all-wheel drive with an automatic gearbox and a two-speed transfer case. Air suspension on many versions: at launch it was standard on the 110, while the 90 could have coil springs or air suspension. Check which system your vehicle has before ordering, because a steel-sprung vehicle needs conventional suspension parts instead.
See Defender (L663) suspension for that side of the system.

Defender (L663) air suspension questions
What is the most common air suspension problem on Land Rovers?
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.
Why does my Discovery or Range Rover drop overnight?
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.
