DTC C1130-7A: Air Spring Air Supply - Fluid leak or seal failure: Action
- Check that there is pressure in the air spring. If the air spring is not under pressure, then use the Jaguar Land Rover approved diagnostic equipment to open the corner valve and run the suspension air supply unit. Stop the suspension air supply unit if the gallery pressure exceeds 900 Kpa. Use leak detection spray on the connections to the air spring and the axle valve block to check for leaks while the air spring is being pressurized. If a leak is detected in the air spring unit, replace the air spring damper assembly as required. If a leak is detected in a connection, repair or replace the connector as required. Clear DTCs and retest
- If no leak is evident, then inspect the air spring pipes and the associated axle valve blocks. If a leak is detected, rectify using an approved repair kit or replace the faulty pipe as necessary. Clear the DTCs and retest
