Hi all new to the forum I've a 57 plate x5 3.0d se an I had two air springs blow at once an I replaced both an then it blew up over its normal height so I ised my gt1 to set ride level high an still wouldn't level out so I replaced the level sensors on the rear both sides an had the pump removed an new bearings put in an checked all is working but now I've it back together an the car will blow up an but after short period of time it's goes down again my head is melted with this I've replaced the control unit as well
