Checking the air-spring strut

Checking for leaks

1. Dip the filled air-spring strut completely into a water bath.

NOTE: Before fitting the air-spring strut in the vehicle, carefully blow out and dry all electrical connections and the residual pressure retaining valve with compressed air.

2. There must be no air bubbles rising in the water bath. If no air bubbles can be seen, the air-spring strut can be fitted in the vehicle.

3. If air bubbles appear in the water bath, the air-spring strut must be disassembled again. Replace all sealing rings again. Check the residual pressure retaining valve again visually.

4. Repeat the leak test in the water bath.
