Hi
we had a problem with the hdc fault come up and front end dropping could hear the compressor we changed the brake switch sensor, abs sensor and the ride height (but have recently seen there is a right and left?) after the ride height sensor change it dropped everywhere managed to get back end up again but Speedo wasn’t working then the conpressor stopped working. We changed front air bags as was told it would be them with front end dropping still no sound from compressor so tried new compressor we had the amok so put new amk on. Still no sound from compressor. Changed the rear abs and managed to get speedo working again and not as many lights on to start with but the suspension light is red from turning light on. We have worked out today getting power to the compressor as we did a wire from battery to compressor and it kicks in then did wire from loom near passenger wheel to compressor and it kicks in and then tested the wire that goes to loom and that is getting power. We are really stuck on what to do next
