Land Rover LR3 Air Suspension Diagnosis - Ep. 4

Thank you so much!!

[@lukula2934]

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...

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

[@wafflesquare]

Thank you, Benjamin, for your kind words. It is a humbling compliment. I’m a flawed man who didn’t have a solid example of manhood growing up. I saw myriad examples of evil while serving in the military and 20+ years of police work as well. I try to make every interaction with my kids and my KZbin audience a thoughtful, encouraging interaction. Growing up, I would have given anything to spend quality time in the garage spinning wrenches with my dad so I’m trying to live up to my own idealistic standard.

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

[@billmartin554]

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.

[@wafflesquare]

Thank you Bill! I’m so glad it was helpful.

[@billmartin554]

@@wafflesquare One thing I learned from this video is if I wanted to proactively test my air struts to see if they are having problems or might need change out I could just pull the fuses and leave it overnight. If (the next morning) one or two in particular bottom out then it is a good candidate for change out. Otherwise my compressor will be working overtime to compensate for a leaking strut and I’d never know, thus premature compressor failure.

[@wafflesquare]

Bill check out this video: kzbin.info/www/bejne/lYjVdICpo9aHfK8 Glenn from Protohyp invented a compressor alert that will illuminate on the dash when your compressor is running. Excellent early warning system: compressoralert.com/

[@wafflesquare]

Ramon thank you so much!

[@BC-tz5oo]

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.

[@lukula2934]

Thanks for the heads up...Even if the valve blocks were made of metal the heat would likely ruin the o-rings and seals. The thought of some kid in there with an oxycetylin torch makes me shudder.

[@sonnynteo1232]

[@any0n378]

I find it hard to understand how the tech applied enough heat to the rear valve block to warp it whilst doing alignment work. All the rear alignment is done on the nuckle connected to the rear wheel. There is nothing to adjust on the upper control arm. That valve block is located about a foot inboard of the rear driver wheel well. My advise would be to never go back to that shop.

Sergei thank you for your kind comments. I’ve had my whole family in the LR3 and they were very impressed with how nice the suspension feels.

[@free2chasehappy]

[@elderberry1941]

I also run a heavy amp . short 12 + power line from the battery to the alternator . as it takes a big load off the connection at the starter ..as-well I also run 3 - ground wires - .from the battery. one to the ecm and tcm and one to the engine block . it also helped with resorting 12 vots to my cluster as it was going crazy and only getting 5.7 vots and ending up with lots codes .

[@powervolt748]

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 🏴󠁧󠁢󠁷󠁬󠁳󠁿

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.

Are you are absolutely right. I corrected that in the next video.

[@ThatCivilGuy]

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.

[@ronaldrrootiii6040]

So it got really cold last week and for the first time ever th rear dropped all the way over night. I started it and aired and it was good all day. I repeated the test with the fuse removed and both sides went down not just one so I know it's not a single Leak with self leveling happening. I figured it was the rear air block and I ordered one but I haven't done it yet because I'm waiting for the desiccate gel beads to come from Amazon😂 Now it's been just as cold except it's not doing it quite as bad and now the front and rear are equally dropping overnight not all the way down just maybe from normal to assess worth of drop. Would that mean the front block also or does the center block let air out of front and rear? Or are the front and rear blocks what actually let air out of the front or rear bags and the center air block only gives air from the tank?

[@wafflesquare]

Sounds like the soapy water in a spray bottle test is in order.

[@grantallannos8974]

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!!

[@wafflesquare]

Thank you, Grant. I bought this LR3 for my 12 year old daughter so I have four years to work out all the issues before she can get her license.

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!??

[@wafflesquare]

If the suspension fault happens after 30 minutes it sounds like there could be a leak.

You can remove the fuse which regulates the air flow and then gently relieve the pressure from the valve block. You can also drain the system with the GAP IID tool.

[@Neberheim]

You mentioned that the powder might be from the desiccant; I read on some forums (🧂) that the desiccant will break down to a powder when it ages and it will eventually ruin the compressor. Do you think that’s true, and did you look at replacing the dryer? I wonder if that’s why the compressor was replaced, but maybe the dryer was replaced at the same time and the powder you saw was residual.

[@DiscoGruffalo]

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.

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?

[@wafflesquare]

There is a valve block inside the rear driver’s side wheel well. There could be a leak there if it isn’t coming from the air compressor box.

[@damonearlewine9482]

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!!

[@wafflesquare]

Sounds like there is a leak in the lines or the front air struts. I would replace the o rings leading into the struts as well. Then I would raise the vehicle to off-road height, pull the fuse as demonstrated so the system doesn’t try to level itself, and perform the overnight leak test. I managed to find our leak in the front strut by quietly listening for the hissing leak sound.

[@damonearlewine9482]

@@wafflesquare Wow thanks for the quick reply! I should have mentioned in the comment that I have tested by pulling the fuses overnight, several times now actually, and it still drops only the front and both sides. I've listened for audible leaking as well and didn't hear any. Everything about the problem seems like it should be the valve block. Now, full disclosure, I did buy the o-ring set from Amazon, but I compared the replacements to the originals and they all appeared to be the same size/diameter. They did appear to be slightly thicker, but I didn't think this would be a problem? I could try and put the originals back on after a cleaning? Or maybe it is faulty Amazon o-rings and I should try the ones that you used?

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 😰

[@wafflesquare]

I corrected that in the very next video

[@jaferabuamerah2689]

Thank you soooooo much 😊

[@wafflesquare]

Jafer you are very welcome!!

[@vraja3203]

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

[@wafflesquare]

The Gap IID tool is specifically for Land Rovers and Jaguars. The eBay link is in the description of every video I use it in.

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

[@andrewtraudes2425]

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?

[@wafflesquare]

The kits came with everything I needed.

[@dragosolteanu3381]

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?

[@wafflesquare]

The suspension calibration procedure is for the ride height sensors so I suppose changing o-rings would not affect those. Personally I would calibrate it just to confirm.

[@dragosolteanu3381]

@@wafflesquare thank you for the answer. My problem is that I don't have the tool for calibration. I saw that you have a video with a review for an iCarsoft tool. Will I be able to recalibrate using that tool if I buy one?

[@R1eger25]

just done mine, and no no calibration needed, just some faults at the start till the compressor pumped air back into the system

[@wafflesquare]

Yes it does have the air suspension calibration feature.

[@wafflesquare]

That’s great! Good for you.

[@jamesray3920]

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

[@raymondmendoza9561]

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?

[@wafflesquare]

It is very likely the same o-ring issue I had in the video (dry-rot). I would definitely check the o-rings before ordering new lines.

[@judsonlall9314]

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

[@wafflesquare]

Link in the description of every video

[@croatonTR]

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

[@wafflesquare]

How about the ride height sensors? I would check them as I demonstrated with the GAP ID tool to see if they are reading your manual input. Then I would calibrate the suspension.

[@geoffbown7259]

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

[@wafflesquare]

The link is in the video description: QuickJack 7000L: amzn.to/39PjZiY

[@geoffbown7259]

@wafflesquare I have subscribed to your channel, and that is because, may I say the way you explain things and your camera work as you go through them are, so good sir, it is fantastic, you don't go all technical, and keep it simple to follow. Thank you all the way from Grimsby, North East Lincolnshire UK. All I have to do is remember when you talk about the drivers side, to me that's the passengers side. 🤣

[@wafflesquare]

@geoffbown7259 thank you, Geoff!!

[@Henriilari]

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!😊

[@wafflesquare]

I believe you are talking about the desiccant dryer which dries the incoming air.

[@alexdickens3308]

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

[@wafflesquare]

Pure silicone grease (which came with the o-ring kit).

[@alexdickens3308]

Thanks so much!!! Your awesome!

[@wafflesquare]

You’re very welcome.

[@carlossaavedra1973]

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

[@wafflesquare]

In episode five I demonstrate how to pull the fuse and do a proper overnight leak test without the vehicle trying to level itself. I would perform that test to see where the leak is coming from and go from there.

[@rafaeloreirorodriguez5278]

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.

[@keithfeller5212]

Compressor and 1 air block replaced. I will verify firmware. No dealer within 100 miles. I am new to OBD world becnice if there was a reference book... but whats the fun in that😢

[@keithfeller5212]

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.

[@wafflesquare]

I would start with the overnight leak test with the leveling fuse removed to find your leak. Have you confirmed the compressor firmware matches the compressor installed? I would also confirm all four ride height sensors are sending info to the computer.

[@natehoule567]

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

[@wafflesquare]

Link to the kit is in the description below. It is from the UK.
