Step-by-Step Instructions

 

1. Activate Jack Mode

In the MMI Menu → Car → Systems → Service & Check → Air Suspension: Wheel Change.
This prevents the air suspension from reacting while the vehicle is lifted.

2. Lift the Vehicle

Safely lift the vehicle using a jack or lift.

3. Locate the Original Pressure-Holding Valve

At the top front of the shock absorber is the original pressure-holding valve with the attached air line.

4. Disconnect the Air Line

Carefully unscrew the air line from the valve using a 10 mm wrench.

5. Remove the Original Valve

Use pliers to unscrew and remove the original pressure-holding valve.

⚠️ Caution: Removing the valve will release pressure from the air spring – keep a safe distance and proceed carefully.
