Thread: Air Suspension - slow air leak

Its likely to be cheaper to buy the complete assembly especially ex UK. If the shocks haven't been replaced yet then a good opportunity to replace them both if funds allow.

Assembly part# should be RNB501580 ($263 + frt ex LRdirect.com)
Air-spring part# should be LR016403 ($369 + frt ex LRdirect.com)

Perhaps get after-market assemblies although I wasn't impressed with them.

Graeme,


I'm a bit confused as to what the two part numbers refer to.


Is RNB501580 the complete strut assembly or just the shock? For shocks and spring do you need to order both part numbers?

The first number is the complete assembly whereas the 2nd is only the air-spring. I didn't post the shock number.

Mine appears to have the sinking feeling,lost 30mm both fronts,45mm both rears over three days

Pumps up straight away once started

Measured the heights at all wheels and left a door open for the night,see how they are in the morning.

Valve block is the guess from the indi,they have done a few in D4's,the check valve fails and the pressure drops off overnight.Apparently the vehicle will try to re level even when it is asleep.

The door being open wont have any effect. You need to remove the 20A engine bay suspension fuse or disconnect the battery to prevent levelling to see which corner has the leaking air-spring or corner valve.

To dark and cold to pull the fuse,so left it just to see what happens.

Fronts both lost 22mm each side,rears lost 5mm each side.

Will pull fuse tonight and see what happens,after a run to get it back up.

Is it definitely fuse 26?

As there is also fuse 3,and10 that have EAS symbols?

Thanks

Yes, engine bay fuse 26 (20A). There is also a 5A fuse(3) in the compressor relay feed-back circuit but that one can stay fitted.

Fuse 10 in the passenger compartment fuse panel is the ignition feed, which is the one that gets removed to stop the annoying messages whilst driving with fuse 26 removed to prevent lowering.

So pulled the 26 fuse,doors shut,bonnet open,vehicle dropped same as having door open

Will leave it until tomorrow morning and have another measure,without starting it,but with fuse out.

Points to front valve block,for sure,rear inconclusive ATM.
