Need some help guys. Suspension fault for a few weeks now. Very much intermittent. Had to go back to get the front breaks replaced at my local indy LR garage. Whilst it was in, he plugged in diagnostics and it's came up with an error about not enough air getting through (wish I had asked him what the code was now).
Anyway, he reckons it'll be the compressor that is on it's way out. That said, some days it will run for a while no problem and then all of a sudden, the error comes up. Not had it crash onto it's bump stops or anything as sinister (yet!). When it's ok, it'll allow me to raise and lower. Normal suspension whilst running (ie handling) seems fine.
Question is, does this require a compressor replacement? What do you have to find out before you def have to replace the compressor (ie, is there any way of testing it)?
I have a warranty from the place I bought it from (from a company called Warranties 2000) but am very skeptical about whether it'll be covered. Also, the limit on the claim is max of £500.
Hmmm..... confused.com If in doot, flat oot!!

I've had a suspension fault for the past 3 weeks now and my local Stealer out here in Germany can't diagnose. The fault code is C1A00-1D, which apparently isn't listed with LR when calling their help line??? A bit worrying! Anyone know what this may be? Could the fact that my Disco is a UK model and the German garage are using a different diagnostics? Or could it just be lost in translation as I am a Brit abroad - they think it may need a new air suspension ecu at a cost of 300 euros!

| 4x4 Info display shows right front drops to full low postion |
|
I am getting a "Suspension Fault "message, and have been for the last month or so.
Until today, about the only indication of an actual problem was a bobbing of the nose when I would stop the truck at say a traffic light; also the appearance of a "Suspension Fault" message on the display along with a bong from the bonger; also that it seemed that the air compressor was cycling more than usual.
Today, it occurred to me that I should bring up the 4x4 Info display and see if anything unusual shows.
To my surprise, while driving on relatively smooth pavement, the right front wheel more often than not, showed that it was bobbing up and down relative to the axle line postion. The other three wheels did not show to be moving at all.
Then when I would stop at a traffic light, most often, the right front wheel position display would show the wheel dropping to full low, (wheel centre line full low relative to vehicle). When the wheel bottomed, then I would get a bong from the bonger, and the "Suspension Fault" message on the display. Then while still stopped, the RF wheel display would centre itself, and all would appear well until either the bobbing above and below the line started again, or I came to another stop light and perhaps the wheel display started the full drop cycle again.
I believe in spite of the display, that there was no actual vehicle elevation change, (or a droop to the right corner). When the nose bobbing did occur, I think that was just the truck going high first and then realizing that it was too high and then lowering itself to where it was in the first place.
I assume that there is a problem with the right front wheel height sensor, (or wiring), and that replacing the sensor will solve the problem. I will be taking the truck in after Christmas but prior to, I was hoping for some comments from others with more knowledge of the system than I have. 2005 LR3 HSE 4.4L V8 petrol; Zambezi Silver; 18" x 10 spoke wheels; underside of glass roof located hidden cellular patch antenna; Traxide Dual Battery install; Air Suspension ECU 35P fuse disconnect; PIAA 2500K Yellow Ion H11 Fog Light bulbs; CounterAct LT-2 Capacitive Corrosion control; LLumar AIR80 Blue clear Infra Red blocking side window film; Liftgate manual release; Schrader Valve "air in" mod to OEM air suspension reservoir tank.

Hi All - When my 07 model is not used for a period of say 2-3 days the nearside rear corner of the car noticeably drops so as the wheel arch is very close to the tyre. When the car is started it rises quite quickly and drives ok. Has anyone experienced this. The car is going to a dealer shortly as the warranty expires in March.
Cheers

| both front sensors and 6" of harness replaced |
|
This week, my LR dealer replaced both front wheel height sensors (Right Hand RQH500061 and the Left Hand RQH500071 $CDN39.66 each), plus the electrical plug and about 6 " (150 mm) of associated wiring harness, (Wire Assy-Jum YQM503220 $CDN56.64 each).
The Right Front sensor was showing defective per my before Christmas post, (wheel jumping about on the 4x4 display screen, but not actually doing so - just displaying that it was and hence the compressor starting more than usual and the nose bobbing up and down more than normal), and hence that is what initiated the service visit this week.
Once the HSE was in the shop, and by my choice, I also requested replacement the Left Front sensor at the same time as I understood that there is a reliability concern with the assembly, (last 6" of wire, connector, and the sensor). I myself assumed the concern is the connectors, (jack and plug), and that is the reason for recommended replacement the last 6 inches of the wiring harness and associated plug that snaps into the sensor, as well as installing a new sensor to mate with the new wire/connector.
I guess I am wondering how quick I should be about arranging replacement the two rear sensor assemblies.
I also understand that there are similar concerns related to the existing two rear OE sensors which I chose not to replace at this time.
What was not clear to me however, is just what the real problem actually is.
I kind of assumed that the concern that would lead to the eventual replacement of all four sensors was a connector design defect, (harness or sensor?).
As such, I looked at the pins and connectors on the two removed units and too my surprise, all connectors/pins looked good - nice and clean, and showing so signs of water ingress or rust etc. I also realize that does not mean that there is not some internal continuity problem in the connector that is not readily visible.
Since the basic concern is not clear to me, I wondered if from previous experience, anyone knows of the reason behind the anticipated eventual need to replace all four sensors and 6" of wire/connector on my, (and I guess others), 2005 NA spec HSE and maybe the Euro spec ones as well.
I guess my real question is should I be in any hurry to replace the two rear sensor assemblies? 2005 LR3 HSE 4.4L V8 petrol; Zambezi Silver; 18" x 10 spoke wheels; underside of glass roof located hidden cellular patch antenna; Traxide Dual Battery install; Air Suspension ECU 35P fuse disconnect; PIAA 2500K Yellow Ion H11 Fog Light bulbs; CounterAct LT-2 Capacitive Corrosion control; LLumar AIR80 Blue clear Infra Red blocking side window film; Liftgate manual release; Schrader Valve "air in" mod to OEM air suspension reservoir tank.

I guess I should join the club, having waded through 2 feet of snow to get out of the drive this morning about 20 mins later red suspension fault light and max speed 30mph. Drove for a while with it bouncing then pulled over. Ignition off then on again and hey presto all back to normal. 15 miles later the same thing. with it back working again and showing no fault I can lift and drop the suspension using the switch, car drives ok though I'm not sure it is dropping to access height when I park up.
Any thoughts from anyone.....Am I just putting off the inevitable?

| Can you watch the 4x4 info display? |
|
Do you have the factory display that shows the 4x4 wheel height and where the front wheels are pointing?
If so, I would suggest that you pull that display up and keep and eye on what it shows.
For me, it showed that on nomal paved roads, that three of the wheel axle centrelines remained exactly where one would expect; that is lined up with the main standard height line; however in my case, the Right Front wheel would display as bobbling up and down about an 1/8" (2mm) above and below the level of the other 3 wheels.
Then when I would bring the LR3 to a stop, (say for a red light), often, but not always, the display would show the RF wheel full down, (other 3 OK). When that happened, most often, the suspension light would immediately come on. Then when I started up again, the wheel location display would snap up to centre and then start to bobble again. The suspension light would then go off.
At no time did the vehicle drop to the lower stops, however it would often bobble the nose of the LR3 a bit - lift it high, then lower it, and it would settle out at about standard height.
I also noticed the air compressor running more than normal - cycling quit a bit.
I watched this go on for a week or so and then spoke to my LR dealer. They said watching the display was a good way to attempt to figure out what was happening, and that in my case, most likely, the RF wheel sensor was defective. In other words, the LR3 air suspension system was OK, however the signal system controlling it was not OK.
This is then what led to the recommendation for eventual replacement of all four sensors and associated plugs / wires as this is apparently a common problem. 2005 LR3 HSE 4.4L V8 petrol; Zambezi Silver; 18" x 10 spoke wheels; underside of glass roof located hidden cellular patch antenna; Traxide Dual Battery install; Air Suspension ECU 35P fuse disconnect; PIAA 2500K Yellow Ion H11 Fog Light bulbs; CounterAct LT-2 Capacitive Corrosion control; LLumar AIR80 Blue clear Infra Red blocking side window film; Liftgate manual release; Schrader Valve "air in" mod to OEM air suspension reservoir tank.

| RF Wheel this time displays full down on 4x4 Info Display |
|
To my dismay, my Right Front "wheel displays down" problem is not solved.
Per my previous posts, I thought that replacing the front sensors and some wiring harness was the cure. It was for a week or so, but today, the display shows the RF wheel full down and the suspension light is on again.
Occasionally the light will go off and the wheel display returns to the centered postion, however for the most part the wheel shows as locked full down. Probably this pleases me, as it should make resolving the problem easier than when the fault was intermittent.
The good news is that there is no apparent driveability problem; just the suspeion fault light on and the 4x4 display showing the right front wheel full down.
Does anyone have an ideas as to the solution to the problem? I assume it is something to do with wiring, (as wheel height sensor is new), or a connector somewhere, so ... 2005 LR3 HSE 4.4L V8 petrol; Zambezi Silver; 18" x 10 spoke wheels; underside of glass roof located hidden cellular patch antenna; Traxide Dual Battery install; Air Suspension ECU 35P fuse disconnect; PIAA 2500K Yellow Ion H11 Fog Light bulbs; CounterAct LT-2 Capacitive Corrosion control; LLumar AIR80 Blue clear Infra Red blocking side window film; Liftgate manual release; Schrader Valve "air in" mod to OEM air suspension reservoir tank.

If the suspension is behaving itself otherwise, it sounds like a problem in the info system as the signal from the sensor is ok. 
Try a software update for the 4x4 info. "A society that will trade a little liberty for a little order will lose both- and deserve neither"

| Seemed like corrosion re Connectors and TSB LA-204-001 |
|
Well, as per previous posts, I replaced both front wheel sensors and about 6 inches (150 mm) of associated wire and a week later, the problem returned.
This time the repair per TSB LA-204-001 was performed. This cost me about forty dollars in new connector pins and seven hundred in labour. I hope it works this time.
The TSB relates to the pins in connector pair C2527/C2528 located in the Left Hand Front wheel arch.
Well, late last week, (about two weeks after the connector repair), the yellow suspension light came back on and when I checked the 4x4 Info display, (getting good at that), again the Right Front wheel was showing low. As before, there was no real driveability problem so that kind of suggests software, however four days later, I was down to the bump stops and getting the do not exeed 50 kph, (or whaterver) message.
When I stopped the LR3 and turned the engine off and then restarted, all would for a time be OK, (no light even). Anyway, while the system was working, I raised the vehicle to Off Road Height and by good luck, the sun was out and shone into the RF wheel well and illuminated the sensor cable hanging loose. For whatever reason, the wires had broken/ripped loose from the plug right at the sensor. Today the LR Shop replaced the sensor cable plug and 6 inches of wiring, (again), and all is well at the moment. Also I noted this time, the repaired cable was tied back to the frame with a plastic snap tie.
I must say that when the LR3 was bumping along on the stops and being passed by Chev pickups etc, one tends to think kindly of coil springs.
I will persevere however. I am not about to give up just yet as the air supension if you can keep it going, does have advantages. My 92 Buick Roadmaster that I still have with a bit over 480,000 km on it has rear air suspension - well actually air shock and coil springs, but for GM, that is air suspension. A few years back, I did replace both air shocks once, but that was more because of age of the shocks than any actual air problem.
I also had to do a fix on the air compressor as a power wire going into the motor broke off due to flexing. The fix has resulted in a slight air leak as the compressor is not designed for repair so resealing was of the homedone variety. What I am saying is that air supsension can work and still be working 18 years later. The big difference between the Roadmaster and the LR3 is on the contols side. In the RM, only one height sensor and one preset height, no air tank, and no computer or associated wiring. There is only one 25 amp fuse and therefore one circuit that runs the whole thing and pulling the fuse is the only control that I have on the system.
Contrast that with the LR3 - four air springs that are cross linked, four sensors, one? computer, two 5 amp fuses, one 20 amp, and one 60 amp breaker that I could find - there may be more.
To date, my problems are wiring related - corrosion and bad luck I would say. What I am really saying is that there have not been any air spring problems or dare I say, even compressor problems - just control problems.
It may be that just comes with the sophiscation, and there is not much one can do about it except repair or eliminate. Since the advantages of air outweight the negatives, I guess I will guess reluctantly accept the costs.
One of those costs to reduce the high probability of walking may be the installation of the FASKIT "external air fill" system. This is an air piping and fill system designed and manufactured in Spain by http://www.opcionesavanzadas.com/faskiting.htm I guess it is common and easy to install on the P38 Range Rover, but not so easy on the Disco 3 / LR3.
While I sort of understand how the kit air lines Tee into the existing LR3 lines, I am not certain about how one goes about shutting down the computer and perhaps LR air compressor, (or it is it necessary)? I presume it would be as the reason one would activate the system is upon failure of the stock system. Then once one got the stock system repaired, the FASKIT would just sit there doing nothing?
With the FASKIT system in operation, it would seem to me that the computer operated Land Rover cross link air valves would have to remain closed so that the air one manually pumps into each corner stays there and is isolated from the other corners. I assume by pulling fuses, that would shut the Land Rover system down, but does that also get the "slow to 50 kph" messages and bells going? Probably not, and I presume the engine still runs etc. but I just wonder what else has to be done.
I think I could run all the air lines forward into the engine compartment and locate the fill connector assembly in the front left empty space near the the windshield washer fill spout. There is empty space there in the gasline engine models - no FB heater - here in Canada, we use electric tea kettle heaters installed in the engine block.
Anyway, I think the Land Rover air suspension system is worth the trouble - the advantages outweigh the problems. I believe the first steam locomotives had their problems, as did the first jet engines and jet passenger aircraft. I should also expect that the first air sprung all terrain 4x4 should as well.
It is noted that they are all world firsts - and were designed and built by a seafaring island people - quite an achievement, and not yet equalled by an island people to the East who are also getting an education in how to handle problems. 2005 LR3 HSE 4.4L V8 petrol; Zambezi Silver; 18" x 10 spoke wheels; underside of glass roof located hidden cellular patch antenna; Traxide Dual Battery install; Air Suspension ECU 35P fuse disconnect; PIAA 2500K Yellow Ion H11 Fog Light bulbs; CounterAct LT-2 Capacitive Corrosion control; LLumar AIR80 Blue clear Infra Red blocking side window film; Liftgate manual release; Schrader Valve "air in" mod to OEM air suspension reservoir tank.

| My turn for suspensions issues |
|
After a year and 15000 miles of fault free ownership of my 06 S, it finally happend!
Firstly, bong and orange waring light with "suspension fault, normal height only" followed by "special programs not available" and then just "suspension fault"
Brake bulbs are ok, battery has been checked and is ok, cleared all the mud etc from under the compressor cover still no luck.
Got hold of a Faultmate (Thanks BBS_Spy) to see if was a clearable error but unfortunatley it was not. Looking at the error codes, it's probably the compressor but I'll wait for TFC to come out and do what he does best.
Will report back when it's all fixed. Missing the permagrin

This weekend (now in the third month of ownership) I got my first suspension problem, although it doesn't display a warning light. Whilst driving in convoy from Bristol down to Devon the car following me noticed that the rear passenger side suspension was sitting about an inch lower than the other side. The lob-sidedness is present at all three suspension heights, under different vehicle loads and you can measure a difference in the gap between the tyre and the wheel arch when stationary.
I think it might be a dodgy height sensor or a poor electrical connection, but I have a non-LR warranty so I'll probably let the garage sort it this time. (As they'll probably end up replacing most of the suspension system).
Regards
Simon
