I had been having the exact same issue! I had my LR certified mechanic watch this. He shook his head, laughed, and replaced the relief valve. He had run diagnostics, which DID NOT report a problem, and was able to show them to me. But this fixed it. One other issue that it was not was older Johnson rods ("...this little arm"..."), which can wear out. Land Rover, making mechanics out of owners for over 40 years! I love this thing.

Nice work on the video. Your height adjustment sensors are basically a variable resistor that tells the computer where the suspension is. If you have a Rover that has navigation, you can pull up the 4x4 menu, then watch each sensor as you raise and lower the vehicle. If you see any of the sensor locators jumping around, you have a bad ride height sensor on that corner. You will know which one is bad, because the other sensors will be moving smoothly throughout their operation while going up and down. Hope this helps someone!

By far the most informative video on this common EAS issue. Like all other commentators & reluctant DIY mechanics who love Land Rovers, this video is a lifesaver!

My L320 was down on n/s front . Set system to full height . Got out listened for a possible leak . Found it forward of the strut . Result wheel off splash guard off there it was dosed pipe. 2inches forward of the pipe push fit connection .. . Ordered a new connector. Taped up the pipe. It held height . Will change the pipe connector remove the damaged section as there's plenty to work with . Reconnect job done . I can't believe the amount of people talk rubbish about air sus. Its just not that complicated . In real terms its either compressor / condenser. Valve block, shock or pipes . Its worth the hassle for the ride quality . Most that slag off LR motors obviously don't have one . Yes somethings are a pain in the ass but not as expensive as the internet ney sayers would have you believe . Great videos buddy . Very informative keep up the good work 👍

Great video sir. I am a new owner of a 2008 LR3, and started noticing that it was bowing to me every morning. Took it to a Land Rover specialist and was told I needed $2043 in new air bags. I had seen your channel before I bought the LR3 so I took my LR3 home and did my own testing. Put it in extended height mode, measured, let it sit for 14 hours, re-measured and had lost 3/4" all the way around. I am now doing the second test with the fuse removed. I am feeling very optimistic :) I will let you know my results.

Been pulling my hair out trying to sort this exact problem, great video mate. Thanks

A great video. It's easy to get into procrastination when it comes to LR and RR suspension. Having just replaced the front air struts (157,00 miles - they were original parts) this just confirmed for me that there were no other problems. Simple and easy to follow and understand. Thanks.

Once again you’re videos are amazing and extremely informative. Thank you!

Hola, adquiri un LR3 y estoy teniendo exactamente esos problemas. Voy a empezar mi prueba asi como tu empezaste. Luego te digo lo que concluya. Muchas Gracias.

I own a 2006 LR3 SE with 130k miles on it and love it, like I said before there is nothing like a Rover !

Thanks for the video, mate. I'm still in the market for a Disco 3, and it's hard to filter out the noise about them being unreliable, problematic etc, mostly from people who've never actually owned one. So, to see first hand experience of what can happen, presented with a solution for a DIY mechanic with even my limited skills, is really reassuring. Cheers, from Australia.

Great video, I own a 2008 LR3 SE V8 with 84k miles, your videos are helpful the Land Rover dealer would tell you you need all four new air shocks.

What a clean vehicle, no rust at all. I have some rusty bottom in my 2012, but still in much better shape than other cars

I watched your video researching Suspension Fault for my 2017 Disco Diesel. I don't know if this applies to my model but I will start with your process. Excellent video and very clear.

Excellent, well done. You must have spent a lot of time figuring this out, and a whole lot more time constructing this video. 10/10.

I have owned 3 land cruisers prior to purchasing my lr3. Just love the air suspension. Thank you for all your great help. My lr3 has 208 000 miles used offroad weekly.

I'm having this issue right now on my 2012 Range Rover Supercharger Sport.... I will start diagnosing tomorrow..... Thank you

Great video. Nice one. Respect to your content 🇿🇦🔥🔥

Oxman, Thanks for supporting us LR3 and LR4 owners. I happen to own both models. Appreciate you. Cheers!

You the man! Thx for these videos! We have a 2006 LR3 and still running great

This was very helpful in diagnosing my new to me lr3 that has the light come on once you start driving, waiting on parts to arrive that hopefully fix it!

Wish I could give more than one thumbs up! Really love my 2006 LR3 and love your videos!

Good diagnostic work. Will be interesting to see what the problem turns out to be. Real men can fix their own Land Rovers👍 On the P38 Range Rover there is a relay under the driver's seat that is part of the self-leveling system. Set the car to off-road height and remove that relay. If you have a leaky air bag it will sink only at that corner.

I don't know how i ended up seeing this video, but thank you sir. This was very insightful 💯🇺🇸

have had a 2009 LR 2 for 18 mths, just picked up triple black 2011 LR 4 and it’s dope! Your videos have played a role in my decision, thx!

Excellent work. Your videos helped me a lot. Thank you!

Thanks man for the information, i guessed the Leake issue with the airbags, may be it Leake from the head, just fixed it and let use know how you solve the problem, good luck

I LOVE THIS CHANNEL! Thankyou so much friend for all the info! I have a 2007 LR3 and just in the last couple of weeks I'll be driving and all of the sudden all my warning lights come on then it drops...full drop like a lowrider....I simply turn off the key, start again and raise the suspension to off road...then drive past 35 and it drops to normal height....and is fine for several days...then it does it again...did it twice today! Baffled!

I like the way you explain everything

Thank you my brother I've been trying so hard to fix the problem so now I've got it fixed thank you very much Man god bless you

Opět velice přínosné LR video, skvělá práce. Zdravíme tě příteli :) Ahoj Martin a Věra.

Loving Tour videos! Thinking of buying an LR3 for off-road ventures and daily. Thanks for putting out useful material and Roll Tide... I mean go Longhorns... sorry...

Best and simple trouble shooting right there bro thanks you so much.

Thanks for the excellent and informative video. You may have saved my suspension and sanity. 😁

Brilliant video, great presenter, very comprehensive 👍😎🤙😎

great video/tutorial still new to Landrover & loving it, I have the same issue, did you finally narrow down to what was the exact problem between the height sensor or the relief valve block?

Good work, sir!

So informative

I'm using your video for trouble shooting right now, thanks!

fantastic video , gonna try this on my sport as having fault showing on dash but nothing coming up on the diagnostics when plugged in

Your videos are great. I don’t own a LR, but I really enjoy watching your content with a good cup of coffee! 🙂 Your videos do a WAY better job than any owners manual.

Thanks for sharing. Great video

Great video well explained

265,000 mi on 07 lr3, lowers itself during night, must be the relief valve block. Great info video, thank you sooo much.John Dockery.

So is real pleasure to listen to you you know what you’re talking about Eddie from UK living in Italy moving back to the UK buying the same car as you’ve got online so when it’s delivered I hope I don’t have these kind of problems I’m only paying £8000 🇬🇧🇬🇧🇬🇧🇬🇧🙏🙏🙏🙏🙏

Congratulations, you made 13 min video, that was clear, very informative, helpful and had no wasted time! Thank you. Also I may not be exactly correct.. but for anyone not comfortable with pulling fuses.. you can also leave a door or the tailgate door just slightly ajar, overnight.. did it on my RR Sport. That will also not let it drop. Honestly, I was a bit heartbroken when it sagged at the end, hopefully it was just one of the Vblock solenoids.. I believe there a 3.. let us all know what the solution ended up being.

Great video, thanks

Your a Star! It was my block. Dafydd Wales.

Thanks for the video. Did you ultimately correct the problem?

Great info.

Thx a lot man.

You've solved my problem of suspension

Great Land Rover videos! I've watched them all. Just recently had this same suspension issue and your video helped me diagnose the problem. However when I installed the replacement front valve block and started the engine the front suspension raised up fine but immediately started to lower. The compressor kept running and airing it back up but it wouldn't stay up. So I re-installed the old/original block and it aired up and stayed (until the next morning, as I had already diagnosed the slow leak) I guessing that the new block is faulty, as I've read from several amazon reviewers. But also wondering if it made a mistake on the installation. I did notice that the new block comes with new brass fittings. I didn't really know how to replace these so just ended up screwing the old/original ones directly into the new block. Could this have been the problem? I wouldn't think so as they seem to work fine on the original block. So I'm confused on how to proceed with fixing this issue. Thanks so much for your help!!

Good vid. I’m going to see about putting mine at off road height. I replaced my front airbags in 2017 and no way have I driven more than 75,000 miles since then. I do have a mechanic I trust, but now I’m curious. Thanks!

Thanks Mate!

Thanks for the information,i have LR4 i love my Land i will keep mine until i die!

AWESOME!!! I'm so excited I found your channel. I'm interested in purchasing a 2016 LR4 HSE LUX. What should I look for in this vehicle to make sure I am making a wise choice/purchase?

Very helpful

Mine did this today after dropping my son off to school and normally a 6 minute drive took me 20 because I had to drive under 30mph with my hazard lights because my car kept threatening me to lower! Then it’s hydraulic city if I try to drive at all lol so basically I read it’s a clogged exhaust muffler plug, drill a 3mm hole in it or buy one for about $70 online! And I’ve read all problems solved. It’s under the spare, remove compressor to get to it, going to do this tmrw!

Great vid, thanks for that. I’m off with the squeezy bottle of soapy water!

Great video… so at the end of the day what was the fix?

You are a genius.

Thank you for your vid. I didn’t see you nail down the fault exactly. I see you eliminated the auto height control sensors by disabling the electronic system, and entire front end sagged. Since both air springs wouldn’t be leaking, that means the valve block was leaking the pressure from both front air springs……right??

Greta video! Sorry if you already answered this, but I did not see it. Did you ever figure out what your specific problem was with your LR3 lowering in this video? Thanks.

You're supposed to push up on the valve block to move those rubber grommets to the larger holes where they can slip out but I suppose there's more than one way to skin a cat. Good video. Just rebuilt the rear valve block.

Hey I had a question about the fuse for that sensor . If you have the coil installed would you essentially remove that fuse ??? I’m still getting the red light you spoke of after installing the heavy duty coil with the flash key it comes with . It’s really annoying lol . Like my Rover is not rising lol

Hello from Cambodia, I've got a RRS 2006, 2.7td with height level issues similar to this video information. The passenger side is always lower than the drivers side, plus the front deflates over night. How can l recalibrate those height sensors without the special plugin EAS reader? I watched a guy on YT from Germany who made adjustable link arms, so he could increase or decrease the angle. This fooled the ECU and he could balanced each individual wheel, any recommendations will be much appreciated. Thanks in anticipation.

Thanks... So the cheaper sensors work? My compressor turns on for like a minute.. then the height lights turn off.. truck is in regular height mode..

Should you check underneath both side step bars for any rusted or corrosive spot?

Great video, very thorough indeed, but will you be able to make it to the fuel station?

Hey man, just want to say I've been watching all of your videos and they are extremely informative and helpful. Any chance you would add a headmount/android stereo? I have the same model of yours and would love to add some cosmetic upgrades. Also have you had an issue with your rear parking aid sensors? Known of a quick fix? Cheers from Canada.

Good info my LR3 is having somewhat of a similar problem While I’m driving that light comes on and then I get the suspension fault indicator. Sometimes it even goes further than that when the vehicle is in motion I get that same light but in red and the vehicle starts releasing all the air.

Dude, you are the LR3 Guru!

Hey man I love all your videos I have a 2006 it’s always giving HDC system fault I replaced all my air suspensions but still the rover is not lifting it’s sleeping on 1 side ( I charged a dead battery and fitted it) if you could help it would be great thank you

I got a Land rover 2012 LR4 and want/ need to change my rear air suspension shocks and pump because I get the "Suspension Fault" Error. Do I need a diagnostic tool to let the air go out or can I just disconnect the battery? Thanks!

Hi , do you perhaps know what the valve blocks o-rings sizes are?🤔

Great video. Any idea if the LR4 (2016) can be troubleshot the same way?

Just wanna say thanks . I have an issue ,and it is sometimes when driving landrover, my radio and dash gone ,then start lights flashing blinking and after few minutes again back ?

Thanks! Would be nice to know your opinion on the new defender 🙂

Hello sir. Thanks for the great videos. Did you use the ride height sensors in the link provided to fix your issue? I have an 07 LR3 with an intermittent suspension light and suspect the ride height sensor is the issue. Drove it up to Big Bear and light came on while hitting the bends. Goes away when turned off then back on randomly. Kindly advise. West Covina, Ca

Was it the valve block or the sensor?

شكرا لك

Hi I need your help. I have a suspension fault were the back goes crazy and starts bouncing like crazy. Replace air compressor twice. Thanks max

Gostei muito

if both fronts are lowering then generally its the front valve block if one side was badly dropped then air leak in shock or airline may be broken. the front block same as the rear is designed to send air independently to ether side. so instead of having 4 blocks for one each side of the car there is 3 front, middle, and rear...but in the block itself there is 3 valves 1 valve for left side 1 for right side and another valve for air to enter the block. best thing to do is change the block. then if its still lowering or air leaking check teh air bag/struct...if you think the height sensor with or without lift rods if 1 side was to lower the other side would follow and lower or higher. if not broken and what i mean is like if 1 side is dead on bump stop and the other side is at normal height. then that's obvious its a height sensor but in this case where 1 side is only dropping a little bit but other side is not then i would be changing air block. because that's the first thing to receive air from middle block first...so before the bags get air the blocks get it first.....hope this helps. i had the same problem with my discovery 3 but all 4 was dead on bump stops and after changing just the front air block i stood up and went hang on if all 4 are down then its gotta be middle block because thats the first block to receive air from the compressor, or its the compressor it self or 1 other thing, and there was literally 1 other thing ?.. i'll let you take a guess first

Not having this issue but great video as always. I cant figure out for the love of all things how to get my lr3 to go into access height. Any help would be appreciated. TIA

Green tube is drivers side (left in US), tube with white stripe is supply.

Hi we have the suspension emblem on our dash but we can't find out if our compressor is the problem canni hear compressure when engine running Trev in sunny cape Town south africa 2010 model disc3

I am totally slammed. I have a 2006 LR3 HSE and I still don’t know what is causing the issue. Should I just go with coils?

Realizing this is a year or so old now, @oxmanagain, if the height stays solid overnight with the fuse pulled it is down to the relief valve or the block?

Question; I need to change my Tensioner on my 2005 LR3. Is is necessary to remove the fan also? Let me know please. thanks.

So I really enjoy your videos and have learned a lot from you, I am having I similar problem, Im getting the suspension fault at 18 to 20 minutes of driving, no sinking in height while driving. going to use your method To see if I have a leak. Thoughts??

if you have a problem with the suspension airbags, you can purchase just the airbags from arrnott industries.

Thanks for this video I will look into it also do you have any info why the ABS BRAKE and Transaction light will be on the dash I purchased a IID Tool and can't clear the fault's well there's 3 I can't clear also I get HDC systems not available and Suspension Lowered at first than after Suspension Normal Height Only Codes are B0002-1B (AF) B1C57-14 (2F) P080A-00 (2F)

Hey OxeMan, I know you’ve mentioned in the past about getting a new or newer Land Rover LR 4, which one, better yet which year do you think is the best?

Why not drive it without fuse? What if it's temporary like to get home or something?

What if ur 2006 rover is stuck in high suspension and wont lower? Im new and green on this so any help great

Get my sport back tomorrow its hard a new bag front left and my mechanic said its still saggin but not losing air like previous i wil report backafter the weekend once i finish this fix

Thanks (2008 LR3, 170k)

Any updates on this, did replacing the sensor fix the issue? I am having the issue. But all four suspensions are flat down to the tires touching. Both air suspensions and air compressors are relatively new. But yeah, I got suspension fault and it wouldn't go up. Thanks
