📋 Procedure

1. ⚠ If the residual pressure valve is sticking and does not let out any air, the vehicle must be raised on a lifting platform in order to renew the valve. The wheels must be free.When disconnecting the air pipe there is a risk of loosening the residual pressure valve at the same time.If the vehicle is not raised on a lifting platform the suspension will immediately drop on the side where the residual pressure valve is slackened. This would cause an acute injury risk, as arms would be trapped.The vehicle must remain on the lifting platform until a new residual pressure valve has been installed and the suspension strut (air suspension) has been recharged. — Put vehicle on lifting platform and raise until wheels are free to turn.
2. Clean area around pipe connection.
3. Disconnect air supply line and seal off connections.
4. Unscrew residual pressure valve (1) from suspension strut (air suspension) using socket T10158/1(2).
5. Screw in residual pressure valve and tighten to 10 Nm using socket T10158/1. — 10 Nm (7.4 lb-ft)
