Thread: SLS - air discharge - really weird

hi mate, the car will self level an drop on there guts when you tern it off, its so its easier to get things out the back, if there is no leaks i wouldn't worry bout it,

the valves do make a noise when they work, have you owned the car since new, its probably you haven't notest it before somehow,

if the rear of the disco is lifted when its stationary,. the heights sensors still work even if the engine is running for up to 25 mins i think after the engine is stopped. that means it will let air out of the air springs if the rear is lifted, might be that the kids jumping up and down is making the sensors let air out. i know if i lift my caravan up on the jockey wheel while attached to disco, the air suspension tries to let it down.

The car will adjust the height if the load on the rear changes even with the engine off, how ever it should DEF NOT drop to the bumpstops, if its doing that, you either have a really big leak, or your height sensors are faulty.

sometimes the leak is under the fold in the bag or at the seal and will only leak when the car is at the right angle, the mass shifts the bag and exposes the leak.

my left hand bag would leak when parked roadside and the camber of the road shifted the vehicle mass. it would go down to the bumpstop (which it should not do). i could also get it to leak by rocking the car side to side (like having kids jump around in the boot). if the compressor runs after the car is turned off (it goes in short bursts) consistently then this is also consistent with a leak.

best to change the bags over asap if there is a leak as the compressor is most likely working overtime with the danger of it giving up.

changing bags is not that difficult. shop around for the best price (i recently paid $400 for an oem bag)
