Thread: My Disco's Drooping

I came back from five weeks away and my D3 was sitting on it's bump stops - it was checked out during a service at MLR and it was the front crosslink valve assembly for the air suspension that was leaking ... all fixed under my Allianz extended warranty ... so I'm riding high again.
cheers

Thanks - fingers crossed it is a semi-simple one.

It could just due to the recent hot weather. During the day the air in the rear airsprings expands more than the fronts so the suspension levels, releasing air from the rear. As the air cools the rear drops lower than the front so the front is lowered to match. Next day the same process is repeated until eventually the vehicle is quite low although I've never seen it lower than about access height. I watched mine do this several times recently.

If you're concerned then the ecu can be disabled by removing the suspension ecu main engine bay fuse which will reveal whether there's an air leak or it was caused by the ecu periodically re-levelling.

If the battery is left connected, the car will periodically wake up and "self-level". This involves only reducing height ie it cannot lift a corner, only bring all the others down to "level" the car. If one corner is slightly down (for whatever reason), then the others will be brought down to match.

Best way to find out if you have a leak is to disconnect the battery, then only the offending corner will droop.

Cheers,

Gordon

Added: Graeme and I must of been typing at the same time! As he said, you can also disable the EAS, rather than disconnect the battery.

Will monitor and report back. Car was under cover but our old carport has very uneven brickpaving that has highs and lows where it has sunk over the years. May be the cause.

Just to revive a recent thread.....

I've been testing my D3 over the last couple of nights to make sure the suspension is leak free.

First night I raised it to extended height, disconnected the battery and by the following afternoon the rear left wheel was about 40mm lower than the right.

Last night, I again left it at extended height, but with the battery connected, and the rear had dropped to below normal height, but the front was at normal height.

Does it sound like I'm needing to chase a leak at the rear? If so, I hope it's as obvious as the one at the front!

Yep, get a spray bottle out with a soapy water solution in it.
As you mentioned yes I'd test out the connection right on top of the strut. Next step would be the valve block. But it sounds like it's only on the airline to the left rear.
