I am in UK . I have a Range Rover Sport 2005 and this video was invaluable in getting to the bottom of my suspension problems . very well explained and informative.Thank you.

OK...While I appreciate and respect your diligence in restoration of this system, there is what I believe to be an elephant in the room here. My experience with air compressors in general taught me that any tank becomes a reservoir for water and eventually rust. Air has water in it and steel tanks are not lined or even coated on the inside. I've had tanks develop leaks due to corrosion from the inside out. Now I've seen videos of these LR3 tanks being inspected after replacement, and they are always infiltrated with water and rust or crud. The system apparently is designed to "dump" pressure when needed for equalizing the 4 shocks. This means the central valve block will allow whatever is in the tank to reverse its flow. I'm not at all convinced of the effectiveness of the desiccant to prevent any moisture from being pumped into the system, especially after seeing the condition of the dryer in the failed pump I'd removed ( soaking wet, corroded and clearly beyond repair). All this to say that rebuilding the 3 valves with a compromised tank seems to guaranty imminent failure...And frankly I don't see how this dirty and wet air wouldn't eventually make its way to the shocks...Replacing the desiccant every 2 or 3 yrs. would seem to be required maintenance, at least in climates with high humidity. It would also be nice if these tanks had drain plugs on them for dumping water similar to any air compressor tank. This foam intake filter that rarely gets mentioned and is located in the rear driver's side compartment, would also be a good place for a 2nd dryer as protection against contamination. Seems like it wouldn't be too tough to retrofit such a device...With the cost of all these components it would seem to be a good investment.. Just my 2 cents...

2006 the Discoverys were still using the Hitachi compressor, they changed to AMK in the wake of the Japan Tsunami making Hitachis hard to source. Great explanatory video!

You Sir are the father I always needed . Thank you very much for all your dedication on quality work.

This is the most helpful LR3 Mechanical video I've ever used. This has been monumental in repairing my air system. Thank you!

I have a 2005 LR3 V8 with 250,000 miles and almost the exact same issues, and I was considering giving it away. I am inspired to repair it and save some money. Thanks for the videos. Excellent.

Great video, chasing the problem then the fix. Now to avoid all those issues with the compressor, valve blocks, air shocks, etc. Simply convert your air suspension into coil suspension and never have problems EVER again folks.

Your video production is spot on and much appreciated. Thank you!

Hands down the best air suspension video on KZfaq. Thank you for the outstanding information, great camera work, and editing that makes everything easy to follow. Super helpful in troubleshooting my own issues. Cheers!

One of the best service and repair videos I have seen

Mike, glad I found your channel--instant subscribe from me. I am taking delivery of a 2005 LR3 tomorrow morning with bottomed suspension (thankfully it's coming on a trailer) and will be getting right into the diagnostics you've mentioned here. Your thoroughness and attention to detail is head and shoulders above even the channels with many, many more subscribers and is on par with any big-budget mainstream broadcasting network, in my opinion. Thank you for taking all the time and effort to publish these videos. I know it is a LOT of work to not only do the job for the first time, but also to find the best way to record it for everyone else to learn as well.

Dude thank you for taking to make this. You explain things so well. I learned more about my air suspension in this video than the combination of dozens of others. I feel way more confident tackling my system now.

This repair works great for OEM parts that have not been disturbed. A quick background about me. I do Nondestructive testing and failure/root cause analysis. I took my Land Rover in for an alignment after replacing the front suspension on both sides. I had no suspension issues prior to that. The alignment tech admitted that he had used a torch to loosen up the alignment bolts on the rear, which is common for Land Rovers. After that, my rear suspension dropped to the point where my back tires were touching the fender liner. Unfortunately, at this point it’s he said she said scenario. I can tell you, if inadvertent heat is applied to the front or rear distribution valve (which both are unprotected), it will warp the plastic beyond repair and the rebuild kit will not work. In this case, $140 to repair it myself was a lot cheaper than fighting it. Something for land rover owners to keep in mind. Do not apply heat to HDPFE, ABF or any fiber reinforced plastics. The heat will warp the material beyond repair.

On my 2nd RR hse. Grew up a mancave MacGyver so I truly appreciate videos. Very articulate, thorough and "English" lol. Thank you for all of your efforts ! Scott

Brilliant write up of the suspension errors that can sometimes occur, for my sins had land rovers for over 30 x years, lol , have a D3 myself and had to virtually rebuild my suspension with replacing things like the front struts , compressor , air tank etc , was in a right mess from previous owners , alas found that many try and repair these on a shoestring by cutting corners , really enjoying ur videos , credit to u as indeed understand how fiddly some jobs can be on the D3’s , worst jobs were replacing the rear upper wishbones , had to cut them out in the end , look forward to future videos and thank u so much for sharing

One of those rare very detailed videos. Great job. Thanks!

Hi from Algeria. Thank you so much for taking time to elaborate this helpfull video. I have the same issue than you and will check my valve solenoid blocks right now!

Great super helpful video, explanation and description.

you are so calm and collected, this makes me want to go and do this service myself just because you make it look so satisfying. plus it can only do good for the air suspension system.

Здравствуйте. Я из России. Спасибо вам за прекрасное позновательное видео. У меня такая же проблема, закажу ремкомплект и займусь ремонтом. Спасибо вам

Great video! Best comprehensive walkthrough of the suspension system. Very useful and looking forward to more of your videos.

Great clear no nonsense video. Thank you, much appreciated

Nice video! To make installation easier, I put the o-rings on first then apply the grease.

Gr8 explanation! keep up the good work, but I have a small comment. The outdoor temp sensor you spoke about is the tier pressure sensor Antenna....The temperature sensor is located in the middle of the front bumper, near where the air enters to cool down the radiator.

I’ve watched a lot of Rover dyi’s and by far you are one of my favorite. Very detailed methodical and if your doing this might as well check this part out and clean this up. Love the way you operate. Just watched your video today and subscribed. Good job love a honest professional.

I'm really enjoying your videos, you come across so very well. Clear, precise and to the point with good close ups of what you're actually doing which is so important. I have a Discovery 3 2.7 TDV6 and have now owned it for 4 years as of today 12th December 2022! I replaced the seals in the front valve block when I first purchased it and then went on to replace all 4 struts even though it was only leaking from 1 front passenger side. Mine too had the original struts from the factory date stamped March 2007 and all were badly corroded so replaced them all to be done with any further issues with them for another 10 years hopefully. However I never replaced the o rings in the centre valve block or the rear so I was very interested to watch your video on this as I'll be doing those soon. One very important thing to note when flashing software and changing CCF files etc is to always have the battery connected to a power supply via a suitable battery charger with a supply feature as otherwise you can brick the ECU. GAP actually state this somewhere in their literature. I use a CTEK MXS25 which works great and has a battery reconditioning feature also. Keep the videos coming, I'll be watching them all 👍 P.S. your daughter is very lucky to have a father like you 😊 All the best from North Wales, UK 🏴󠁧󠁢󠁷󠁬󠁳󠁿

Excellent video! Really detailed and well explained. Thank you so much for your time and effort. Much appreciated.

Love the way you are taking care of this car!! Thanks for sharing and I wish you a merry Christmas and a happy new year!!

Awesome series! Been enjoying it a lot. at 25:30, I believe that's a TPMS antenna, the ambient air temperature sensor lives on the front of the car behind the bumper iirc.

Great video very helpfull gonna follow your steps

Hi! Thanks a Lot for this great Video! im going to get those rings and do the job following your very useful tips! Hi from Brazil!

Awesome video. Cant wait to do the same when i get mine. Well done!

Very concise video Mr Waffle. I was quite envious of the condition underneath your discovery. Mine is 5 years old and was purchased from a seaboard dealer in the UK and the whole chassis has lost its paint.

What a detailed and well produced video!

Excellent work Thank you

I saw you have 6 Ventilation module codes. Those are very common when your battery is getting weak. If your battery is 2-4 years old, you'll want to have it load tested and consider replacing. These vehicles are very sensitive to voltage.

At minute 25:27 That's the TIRE PRESSURE SENSOR and NOT temperature outdoor sensor. Thanks for the video.

awesome precise explanation.

Excellent work!!

Great episode.

Very good. Thanks!

Great vid 👍👍thankyou 🇬🇧

Really thank u so much bro u r the best go forward dear

another great video Mike - very thorough. You may not be a mechanic but you come across like my old uni engineering lecturer lol. good to see you have the AMK - I had to swap out my old Hitachi about a year ago so got an AMK and flashed the firmware at same time. The mounting bracket for the AMK is a lovely piece of machined aluminium, or at least it is now (as at 2021) looking forward to seeing more videos but also hoping you don't have any further failures that need in depth work - the Electric Parking brake is fun to work on...not!!

Excellent professional and precise content! Your videos are some of the best out there on YT. Curious to know which jack you have? I have an `08 lr3 and would like to tackle the Tranny Maintenance you did a video on.

Thank you

Great video, one thing: that is the wheel sensor antenna behind the right front wheel well…..transmission was a great video also

This is great Mike

Hi Mike, the best most comprehensive video i've seen :) well done! .. quick question.. did you have to release all the air out of the system before disconnecting the valve blocks?

amazing video

i love watch your video is like netflix i laren to much from you big love from barcelona

Thank you soooooo much 😊

Brillian video

It’s so helpful boss❤

Excellent video! I wonder if you have an idea of how much it would have cost to buy 3 new blocks versus the cost of the o-rings and the amount of time it took you to switch them out. For less adventurous types like myself, it would be cool to know the cost and effort difference. Thanks for the video!

Another great video. Hard to find a mechanic that is as thorough as you ... sad to say

So glad I found your site...Just bought an '06 LR3. Picking it up tomorrow but the air suspension is totally messed up. Should be an interesting hr. long drive back home. Ordered my gap tool and ordered the o ring kit from 4x4. Hope its not too long a wait. I'm cautiously excited to own this car. Always wanted one. That lift looks interesting as well, do you like it? Your very considerate and meticulous and I really appreciate that.

Awesome video very high value information My question for you where did you buy your lift and if is an affordable price God bless you and your family

We have had our LR3 for 14 months. In that time apart from batteries (yes, plural) it has had 5 air springs, two valve blocks and 4 compressors, the last one in February 2023 - and today the Suspension fault light came on, Normal Ride Height Only. I love the LR3 but...

Great video. I am troubleshooting my wife’s 2006 Range Rover Sport. She’s got the 4.2SC and that Front Valve block is a pain to access due to aux cooler. What engine do you have in that LR3 v6 or v8?

Fantastic video. Is this the same compressor system used on the LR4? I'm looking, youtube keeps showing compressors for LR3. Again, great video.

Great video…liked and subscribed. I recently changed my compressor and while it works fine with no faults….the vehicle is now spitting excess air after the compressor runs and also after I turn the vehicle off. I know that it is normal for some air to release after turning the vehicle off but not during startup. It sounds like the air release is from the rear of the vehicle. Could this be a valve block?

Great video...Thanks! The wife's 2014 LR4 (bought Nov 2022) just gave her a suspension fault today driving from Texas to Florida. I'm in Ohio. It turned off when she shut the car off and got gas, then returned after 30 minutes of driving. It doesn't seem (according to her) to be leaning front/back or side/side or riding rough/bumpy. She doesn't really know the difference from normal to entry level heights so she can't tell me over the phone. She does have to put some weight in the rear of the vehicle coming back so I don't know what to expect. Hopefully it will be this simple!??

Great videos! I am having an issue with the front suspension on my LR3, same year and model. I initially replaced the front valve block with a cheap valve from Amazon and it seemed to work at first but would still intermittently sag in the front overnight. I checked both front air shocks and the valve with soapy water and did not see any visible leaks. So after watching your video I decided to replace the o-rings on the original block and reinstall. Again worked great at first but still had the overnight sag. I'm at a loss on what to do next?? Any advice would be greatly appreciated!!

great video. I was wondering about the scan tool you are using, Is it only for land rovers or is it for all vehicles. Do you have a link for that? thanks

On the initial O ring you showed that was cracked on the air hose, did the O ring kit have a replacement for that?

nice video and i would like to know where to get the scanner to diagnose

Tank you for this video, I learned a lot from it. I also have a question. After replacing all the orings, is it necessary to recalibrate the suspension or not?

Hi brilliant video, can I ask what lift/ jack, are you using please. I am uk

Hey there so I have a 2010 range rover sport I replaced the front air shock bags and after 2 days the truck seems to be going down do you think it can be the valve amd or the sensor as well ? Also the dynamic error code pops up as well

Would this cause to lose traction on turning because mine has been doing

Hey Waffle square! Thank you very much for this great Video! I just replaced my AMK kompressor and now I am surching for some informations about the Air Inlet of these. Since you are also very in to the Air Suspension of this Vehicle: Do you know what the Plastik Tank does where the filtered Air goes to before it is lead to the compresssor? Kind regards from Switzerland!😊

Just replaced my rear valve block but for some reason can’t get the line couplings to snug up without the air line twisting…

How do I update the Discovery or Range Rover for different software of different air compressor manufacturers. You see I have a Range Rover with a hitachi air compressor starting to show a slightly fatigue and I have a brand new Dunlop air compressor that is well accepted on EU markets for Discovery and Range Rovers and the question is how do I update my ecu for new softwares I know this can be done, LR also have been using those compressors over the last few years.

10:45. You don't have a motor temp sensor as you have an AMK compressor. The case is different. So you must have the wrong firmware. Also if you have no pressure in the tank in the morning, you have a leak in the tank or reservoir valve. The compressor relay rarely fails. You can substitute it with the heated windscreen relay next door. 26:00 TPMS antenna, not a temp sensor.

What's the name of the grease used? We absolutely love your video's!

Do you apply teflon tape to the house fittings when you reinstall?

hey did all that work fix the problem Trying to let the mechanic have a place to start my lr3 2006 is doing the same thing

Did you order this kit from the UK? Or somewhere else stateside?

For me red light suspension come on after exceeding 80km/h then do not exceed 30 m/h do any has this problem please help

Unfortunately I have the same problem with the suspension bouncing everywhere. I tried the soap trick on the valve body no leak and then on the compressor where the air lines come out to the valve body, and it's leaky from where the hose connects to the compressor side. Do i need to replace the line or maybe there an o ring on that side?

Where can I get the GAP tool ? I have a 2006 Land Rover lr3 I was wondering where I could get this tool ?

Hello, is it possible to update the air compressor firmware using the launch scan tool? Awesome Video 👍👍👍 Thanks.

Hey Mike , I have a question. My L3 has all brand new air suspension parts however while driving it the nose goes up and down randomly. My tech couldnt figure it out and it drives us nuts. Any idea what would be the reason for this random nose up and down action? Again i have all new sensors and parts and there is no leak in the system. Thx

Sense I bought arnot air springs I also bought a new arnot air compressor just installed new air compressor the old was the original one it fell apart as I'm taking it out I finally had to connect my gap tool and reinstall firmware and now I have all the functions but rover still won't air up this is nut all work fine until I replaced all new upper and lower control arms and air suspension this is nuts

I replaced the front left strut on an LR4 today. No heat shield that I saw that I could remove but was able to get a socket on it and turn it ever so slightly and work it off. Was planning on replacing the passenger side front but I couldn’t get the rear but on that one if anyone has insight on it.

Hi what is the gab tool and can I purchase it and from where ? Sherwin

Mr mike I hate to correct you on one of your comments , that is not and outdoor temperature sensor 😱 it is actually a Tpms transponder part # 51732zt, there one more on right rear wheel well , the land rover is such a unique suv and very sensitive to things being unplugged I just replaced my cigarette plug in console but didn't plug back in immediate once I put in new 12v plug I tried to start my car it wouldn't start until I plug all 3 connection on lower console 😱 omg, , know I am having issue with air suspenion fault, I finally got around to installing all upper , lower control arms and all new air bags in thinking because I unplugged the TPMS sensor transponder might be keeping lr3 from inflation air bags , I find out next time I go home , in a truck driver so it might be 3 weeks b4 home again to know for sure , i do have gap tool nothing worked on trying to calibrating so I'm thinking plug up the Tpms sensor transponder in hoping , it worked fine b4 I replaced air bags , my mistake was not disconnecting battery 😰

I am going nuts a few weeks ago I installed new air suspension now u have a suspension fault I own a gap too for some strange reason I don't have all the functions as I see in opeople or your gap what am I doing wrong I hook up to computer updated I don't see where it tells you what kind of air compressor I have or other functions functions like turning on air compressor or manually raises rover , all the air out tank before I replaced air suspension everything worked fine any suggestions on what I am doing wrong with this gap tool

A friend has had some work done to his 2006 and now the air compressor wont come on at all and he's brought it to me to fix. Fuses are good, relay functions properly in other slots and on bench. Jumper wire will bring the compressor on. Invalid data from Dynamic Control Module code, occasional rear left height sensor failure. Any suggestions? Can the sensor keep the system from even coming on?

How many o ring kits should we purchase?

One thing I wasn't clear on: the kit only pictures two of the tiniest o-rings used by the center valve (37:55) on the front and rear blocks, but each center valve requires two. Did the kit include 4 or did you not have enough?

My 06 standard height does not maintain while driving. I see the height screen as shown. There must be a leak. But when I start the vehicle raises to standard. Why does it not attempt to raise while in motion. I have to pull over stop and start vehicle to raise it.

Does it read the motor temperature now ?

salve non so se risponderai ma io provo , ti espongo il quesito, ho in officina una discoveri 3 che ha un problema alle sospensioni dalla diagnosi mi dice centralina bruciata , ho sostituito la centralina con una simile ma con qualche numero diverso , alla diagnosi che faccio con w.o,w , della wiurt , mi dice codice vin errato , visto che la centralina prima era su un altra discoveri dello stesso tipo , la domanda è questo strumento che hai puo riscrivere il VIN ? il mio fa solo dei test niente rimapature ciao grazie in eventuali risposta

Hi I have a 08 sport with a suspension vault, I’ve replaced the compressor, checked the struts for leaks, replaced a bad door sensor, and no luck. My compressor won’t turn on by itself but I can bypass the relay and manually fill the bags, my toggle switch to control the EAS doesn’t illuminate either, I’ve replaced all related fuses and relays as well.. any idea what my gremlin could be?

I have a 2006 range rover sport I have codes 110and 118 can u tell me what they are cheeer

Where can I buy this reflash tool whats it called ?

Ok so i checked sensors and replaced them and i replaved the valve blocks. Suddenly one cold morning 2 days ago my struts would not inflate. What could it be. All three valve blocks i replaced. All 4 sensors replaced, pump replaced. Brand new. I cant find a leak anywhere. Opened the resorvor air tank and air comes out. Not sure how to tell if its bad or kloged. Please help😢😢

@33:15 THATS WHAT SHE SAID”
