Thread: SLS sagged this morning

Replaced my air springs in Jan 2011 and now car slowly sags over time when left in garage for a few days.

with the soap test I cannot see any leaks in the bags even when hyper extended via nanocom. there is no leaks in any of the air piping/joins.

I have replaced each Arnotts bag in turn with the old good spare OEM bag and it still goes down.

Before I send off for a new set?

Is there any thing at all other than the bags and lines/joins I can check as a possible cause.


I have noticed there is faint clockwork noise at the compressor that runs continuously and stops when the connectors are pulled off, starts again when they are plugged back in. What is that?

Paddocks have dunlops air springs avail for 68quid @

Guys save yourself alot of time and worry, contact the Airbag Man in Queensland and order a couple of Dunlop bags, quality and priceand overnight delivery to most places in Oz

Hello there rear bag we would like to help if we can
RKB101200 part SPRING $250.00 gen land rover
RKB101200 part SPRING $190.00 not gen

not in stock at the moment will be in on next boat or we could air freight free delivery with in Perth W.A so would be a small cost to send to the rest of oz thank you Simon

go and buy a metre of 4mm ID airline and two push in connectors and two schrader valves($20) from Pirteck, jack up the chassis, remove lines from tops of airbags(are they push-in?) add a 200 mm length of new 4mm line add schrader valves, put 70lb in the bags, leave overnight.
This will tell you where the leak is,, (very unlikely its a hose leak)

apparently the SLS will try and self level for a short while after switch-off, could it be those noises?


I replaced my tyres with solid rubber ones after a flat.
Do I miss the ride and handling?
Bloody oath!

Alpick,
The Arnott bags are the problem. They leak From the top as a factory fault. I had 6 bags replaced under warranty. I gave up and bought the genuines from Paddocks. Perfect ever since.
