Sounds like a lot of problems with air springs. Why not covert to normal springs and shocks.
Because normal springs and shocks ride like an utter dog!
The ACE suspension aid, and the cushioning of the airbags is a real joy - the system really isn't as bad as it seems, you just need to ensure that you fix leaks immediately so you don't turn a replacement bag into a replacement compressor too....
2nd hand Contitech bags can be bought for 25 notes and self fitted - it's actually quite cheap to run if you know what you're doing.

Fair enough, depends on what you use it for
It doesn't really matter.
If it's mainly on-road, the ACE system outperforms springs/shocks any day of the week for body roll control.
If it's mainly off-road, the height adjustable air suspension could be pretty damn useful and rides very smoothly indeed over the roughest of ruts.

i find with many i know good springs and shocks with ace better ride than air
Firstly Hello everyone this is my first post.
I have read all 17 pages just to make sure I was not going over old ground and not to waste any ones time.
I have replaced both bags and compressor last year (land rover parts) and the last couple of days my ride height has dropped without being able to raise it. doors bonnet closed So I replaced ride height sensors again genuine parts. Disconected battery.
No change , no leaks from pipes, compressor or bags all tested with soapy water.
So on further investigation I have found on the valve block the air supply for the right bag is pumping but not the left (blue plug nearest). If I change over plugs the left will pump. So my conclusion is no live feed coming through the blue plug ( yellow and white wire) but if I press the height raise button with a test bulb it lights, but if all connected up no difference is obvious !
Now if only one side is pumping the suspension wont rise ? as it is leveling with the deflated side ? Is that right?
So when I start up the compressor runs but no lift , when I press the off road button compressor runs but no lift. When I do undo the connectors on the valve block some air does escape but not much. I can lift both sides if firing air in pipes with my workshop compressor.
Is this the ecu ? is this the sign of it needing recalibrating?
Or am I missing something obvious and just being really thick?
Thanks for reading and any pointers will be kindly received

From what you've described - the compressor has failed in part. I'd be digging out the receipt and taking it back to the main dealer for a replacement as a warranty issue if I were you - and quickly too before time runs out!
Even if it has run out - if you've shelled out 400+ notes for a genuine item from a main dealer, you can reasonably expect it to last more than a year in any case. If they don't want to be reasonable, I'd suggest lightly that legal action may need to be considered if they're not prepared to help you out. It's a V E R Y expensive part!
Hi thanks for the reply but no its the power supply going to the compressor/valve block that's failed ie the yellow and white wire into the blue connector that's not charged so no air is being sent to the spring. but if I swop the blue for white (connector left for right) the valve pumps so the compressor seems to be working.
It cost less than £300 but your right it is expensive but such is life eh !

After checking as it was 18 months since I bought it and not covered, I had nothing to lose if I started to examine internally the compressor as you mentioned ! I had it sorted !
Allen key in exhaust air valve cleaned up the disc as it was slightly tarnished refitted and up she raised. Now I can rest. Thanks for your replies It helped and saved me talking to myself.

First time I've heard of that as a fix!
Any chance of posting some pics of what you did for the everyone to have a look at?
If you look at Battenburgs op.
the labelled pic shows 'exhaust air valve', in the centre of the white facia is a hole that allows an allen key to fit precisely.
Pushing the allen key in it turns clockwise (if i remember correctly). you can move the facia roughly quater of a turn untill the luggs that hold it in place slide out in groves under pressure from the spring behind.
You now have the facia with allen key inserted and a spring, if you look inside the hole there is a small disc that the spring holds down, on the underside it seemed to be plastic/rubber coated and the top side alli , shiny anyway.
This disc was cleaned around the outer edges carefully and avoiding damaging the plastic/rubber coated side as it obviously forms a tight seal under the pressure from the spring.
When all parts where cleaned I put the disc , plastic /rubber side down in the hole, the spring on the back of the facia (there is a little peg to seat it) , lined up the lugs in the groves pushed it back in together and turned anticlockwise till the lugs seated.
Took no more than 5 mins
I hope that makes sense I will put pics if needed.

Hello,
I am writing from Brazil. I really need help. I replaced the rear airbag´s suspension after I noticed that Disc 2 was not keeping the height when packed with seven passengers.
At last, after using all the passengers, the system warning light flashed and the car hit the end of suspension stroke.
Now, replace the bags, but the car does not raise. The compressor is working, sending air to the tube (the tube was tested with the connection of the bag), but it seems that no force and can not traget the ideal pressure and lift the car. Even the car suspended the compressor can not inflate the bag more than half of the predicted.
Nanocom showed no failure, and there are no leaks in the line or in bags. The valves are ok too.
We tested the system by injecting air directly into the valve with a mechanical compressor and releasing external valves through Nanocom and the car up quickly and remained so throughout the weekend.
The air line tubes of compressor to the air springs are okay.
Someone had something like that?
It could be the relay?
How to measure the pressure and what is the pressure of the compressor?
For some relador pressure in the compressor which could be replaced or adjusted?
I do not want to change the airbags by the springs.
Waiting,
Rones

its actually the pressure limiting valve.
good idea to clean if compressor doesnt hold pressure

Hi
According to Rave, when switching off the ignition and opening a door the air suspension is supposed to drop 20mm from normal ride height.
The suspension is then, supposed to rise again when the engine is running with doors shut. The suspension on my truck only does this occasionally. Most of the time it just stays at the same height and doesn't move. I have checked fuses and for codes, but none are logged.
Beginning to think its slabs ecu that's faulty. Door switches work, interior lights come on on opening any of the doors.
Anyone come across this suspension issue?

yes, no worryes m8... it's nothing wrong with it...depends on which position are the height sensors when u leave the car or how much the suspension rises after u le3ft the car ... the sensors need a certain move to give that command(i mean the lowering thing).... read more carefull the statement from rave...it's not for the case when u just turn ignition and open the door... the sensors must "feel" that load was removed from the vehicle ...and it's up to 20mm ...it will do that when the load in the vehicle(in some cases it means just you
) "pushed" down the suspension a bit... then after u left the car the SLS wants to relevel it.... ask somebody weighty to join you to a short ride then stop and leave the car together... or put something heavy in the boot then remove it immediately after u turned ignition off...u'll see that it works .... unless u are right and the ECU or sensors are missbehaveing.

Hi there I'm pleased someone has put this out there it's a great help to all of us cheers
