Picture of Land Rover Discovery 2 Air Suspension Wabco Compressor Removal.

It is very common that the piston ring seal within the Wabco compressor wears down reducing compressor performance leading to noisy, slow rising or even inactive air suspension. This guide shows how to remove the compressor so that the piston ring can be replaced using our repair kit, available from us X8R Ltd.

First, depressurize the SLS air system.

After depressurization, approximately 1 bar (15 lbf.in 2) air pressure remains in the system.

WARNING: Ensure the air suspension system is made safe before commencing work. Otherwise the chassis may lower onto the bump stops during repair.

1. Raise rear of vehicle.

WARNING: Do not work on or under a vehicle supported only by a jack. Always support the vehicle on safety stands.


2. Disconnect the height sensor multiplug.

3. Remove bolt securing height sensor link to radius arm.

4. Remove 2 bolts securing height sensor to chassis and remove height sensor.
