Thank you! Every other video shows the RR on a lift for this procedure. Seeing this makes it clear I can tackle this one myself and give my wallet a break!
Eureka! The exact fault as you described; I replaced as per your video with OEM part on Tuesday and it is now back to normal! Not sure I needed the compressor the dealer scan code indicated, but hey, it's a 16 years old vehicle so cannot hurt. The original plug was a 6-pin and the new plug is a 3-pin. Thinking maybe for L/R front wheel optional placement on the original? It only had 3 wires. Thanks again.
Hey there, I got this suspension fault light on the dash too but mine does not let me raise the level at all when I try change height to higher or lower it says "normal ride height only" suspension fault, does this still mean the suspension sensors are the problem?
I would wish that this was more straight forward as you have shown . Firstly I had an active roll fault with wiring connection to the valve block , then cleared with diagnostic , which you need really . Then second fault with rear height sensor , I replaced this and ran guided calibration with diagnostic which would come up with an error .I then found the Active roll module was not active and needed calibrated , so not always so simple !
For me at least: -60k miles: air compressor ($600) -80k miles: lower control arms, swaybar bushings ($300) -90k miles: height sensor (just the front left one) ($60?) -135k miles: air compressor again but I just did a coil conversion to bypass any further suspension issues for the life of the car instead of replacing the compressor ($1,300) The suspension issues aren't too hard to fix, it's just a matter to making sure you're fixing the right part
Thank you for the video. I have an Ml320 that has a similar issue but the dash does not inform you of a problem. Instead I get different heights between the wheels and the wheel arch. And one strut deflates after exiting the car. Raising again while driving and keeping high if the motor is on. Do you think I have a height sensor problem?
For an LR4, the visual display is not like this. How do you know if there is a height sensor issue when there is a suspension fault warning on the console vs. a valve block issue? Car compression system works fine and stays level overnight. Thank you!
Just learning my Range Rover Sport 2012 with 150k miles. Intermittent message do not exceed 30mph suspension fault. I have put about 5k miles on this vehicle in mixed use with no issues. Recently had compressor replaced. Programmed correctlt supposedl by jag rover specialty shop. 250 miles later the warning shows up. 20 degrees outside. Light off next day, 25 degrees, Light on after 1 mile. Light went off, yesterday 50 degrees out. Went for 3 hour spirited drive in mountains yesterday with no issues. Then some lite off roading. No light. Glad for that. Intermittent warning lights are so annoying!
Temperature-related warnings sometimes are due to a low battery. The sensors are really finicky, and a battery just 2 years old can start causing issues. I use a AGM battery and found these are the best and haven't had issues in years. Just something to consider!
As long as you replace the sensor with the same one that was removed it should be OK. If you note obvious height differences with a measuring tape then you may need to.
hi, my LR4 , 2014, front has dropped. Air springs have no leak, the valve block is ok. But the vehicle is not lifting (in front). The compressor is working fine as well. What could be the issue? Thanks
Hi, Hazy! Always love your very detailed tutorials. Thank you! I would get occasional rear sag that would automaticall correct upon start. I would also get random suspention fault warnings. The truck gave a teriibly rough ride over bumps too. About a month ago I replaces the compressor and I just replaced my rear airsprings 2011 RRS HSE and all was fine. It raised up and lowered no problem right after both replacements. After a good test drive with no warnings I figured raise and lower it again for another test... Well, Its stuck up in off road height now and won't let me lower it. Says suspension fault then the usual dont drive over 35mph, etc... I've tried turn off and on numerous times and still no change. Seems the system will not deflate. As soon as I hit the button to lower it sends a suspention fault warning. Absolutley nothing happens. No air comes out, no movement at all... suspension controls just shut down. Even right after startup it will immediately go to fault as soon as I hit the button and try to adjust height to normal. Maybe theres a clog after all the work I did? If you have any ideas, I would be very grateful if you shared. Thanks in advance and thanks again for your great vids! All 4x4 dash info looks even and steady, its just stuck in off road height. When working properly the system fills and raises fast... just for whatever reason right now I cannot get it to go down. Will disconnecting the.battery help? Or do you think this is a height sensor? Or a clog? Help!?? Please? Thank you!
Hmmm it's likely the error is caused by the gallery (air springs) lowering too slowly making the vehicle think there is an obstruction, which then causes it to jump up to extended mode. This would trigger code C1A13-64 Pressure does not decrease when venting gallery. So it's potentially a clog which can usually be fixed by cleaning out the desiccant chamber on the compressor or replacing the exhaust valve. I'd make sure you're having the C1A13 error though first, consider using a code tool to check or have a dealer check.
@@HazyJay Thanks for the speedy reply! Your the best! I have a basic OBD2 scanner and show no codes. I was actually looking for the one you mentioned.(saw it in the comments and on RR threads) I understand what you are saying about the suspension thinking obstruction below truck and shooting into extended mode.., but thats not happening. From past experience, typically if something is under the truck I am promted before lowering and that doesn't happen now. It doesn't put itself in extended mode either. I put it into off road height myself(purposely) and now it will not go down. Thats pretty much it. The 4x4 screen shows the suspention at level in off road height(as it should), but it won't move. Its just stuck there. When I start the truck; the dash display says normal height and the center console height selector switch has the off road height and the center normal ride height symbols lit up, yet no suspension fault in the dash display. At this point I try to lower the suspension and as soon as I touch the height selection button I imediately get the suspension fault and get locked out of the suspension controls. The truck stays in off road height... doesn't change at all. No compressor noise, no air release noises, nothing but the ding and the fault from the dash display. Im not sure its a height sensor as when viewing the 4c4 display all 4 wheels register the proper postion in accordance to the trucks actual height. Could it be a bad relay? Or possibly the exhaust valve? The compressor is only a month old.(bought new). I am truly grateful for you responding and doing what you can to help. I hate to be a bother.... but I do anxiously look forward to your next reply. Your insight is much appreciated. Thank you, Hazy!
I think a bad relay or fuse is more likely, or a burned out ECU, given it errors as soon as you press the button and doesn't even attempt to change heights. I'd check the fuses/relays first since it's cheap/easy, but if they're normal then you'll need someone with a Jaguar/LR diagnostic tool to check and see what exactly is causing the system failure. I hate going to the dealer but that should be a cheap/free diagnostic test, then you can fix it yourself most likely.@@kevinfelisberto4204
@@HazyJay WOW! I wish I could get answers that fast from any local shop or even Google! Thats awesome... Thank you! I will definitely look into the relay/fuses. I did see someone suggest replacing the relay when you do the airsprings as that would be as old and tired as the springs themselves and may not be up to par with the new setup. And as you suggest, if that isn't it then I will have the ECU checked out. I will repost when/if I get this figured out. Lol, I may end up with another question first.🤷♂️ Thanks again for your help! You are a great service to all of us RR aficionados. A true gentleman. 😎👍
@@HazyJay thanks for the quick response, you seem like the only guy on youtube that simply explains the fault and causes and how to fix simply. very basic and straight forward thanks again
Thank you for the video. My screen shows the car is rising but it actually isnt. The lights on the switch will light up but go out and a fault will present. Secondly once or twice a week it will work fine without notice. I am having trouble finding a shop that will work on it. Any suggestions? Thanks Re:2006 full size Range Rover
Whoa thanks for sharing. Just got one of these. Do you know other reasons to look out for Suspesion faults? For example, you mentioned either the compressor or valve blockage. Would it display on dashboard for those specific errors??
Disconnecting the NEGATIVE terminal is ideal in practice (as to minimize chances of shorting out by contact of the POSITIVE terminal to the vehicle’s chassis)
I have a 2006 rrs supercharged... My car was fine and out of boredom i selected calibrate anti roll option then i got e 7 error code and my red suspension light is on... Everything still works ie suspension goes up an down etc but now the red light stays on and fault code C 1 A00-54 - Control module - System programming failure - missing calibration (AB)... 😮... Any advice please 🙏
Hi Hizy. My Range Rover hse 2007 is alway show the (front passenger) suspension not stable ( some time that turn normal height,but sometimes it show very low ) also I cannot rise and lower it by control and my special program are also no light at the control and also not able to control because it said special program off. Last night I park it the front rear look normal stable but my driving backside rear drop down very low! Can you give me some advice?
I have a 2006 lr3 and when I drive it it won’t let me go over 30 mph as if it lost power. But when I let off gas it picks up power until gets to going over 30 mph then it does it again. Please help.
Awesome video. Im running an Lr3 and have just had new blocks front and rear changed. Truck drops down to bump stops overnight... have checked entire system for leaks now. Put it into extended height, removed Fuse 26, and for the first time in 2 years it stayed up. Did the same again in normal height 3 days ago and truck remains up... no warning lights on normally could this be a faulty height sensor... ? I should say the truck drops on all 4 corners not bias to one corner... cheers
Definitely doesn't sound like a leak, system is probably trying to level over and over while it's parked, I'm under the impression it can only DROP and can't RAISE while the car is off. I'd suspect one of the height sensors is off, what does the 4x4 info say though? Do all wheels look level and stable?
I did change the passenger side sensor. The screen on the dash , indicates all OK. Yet, the suspension light, keep coming back after few minutes of driving? What I am missing? Thank you
Awesome short and detailed Vid mate, cheers from OZ. Mine randomly says 'Suspension Fault' only when putting it in raised height and doesn't always appear.. Replaced the Compressor recently. and all 4 wheel sensors appear to be normal. Any Ideas on what the fault for raised height is? Is there a Single sensor or ''Brain'' that all 4 go to? Cheers.
There is a control unit but if it was faulty, you would likely have more severe issues. I'd consider raising the vehicle while watching the 4x4 screen, sometimes the height sensors will start to send weird signals at certain heights and maybe you can catch which one is faulty.
Don't know if you have any insight, but when I got my 06 RR SC, it was on its bump stops. Someone had driven it like that and the front right strut, if you pull the rubber cap off under the hood, sits 1 inch higher than the left one. So much that the cap won't go all the way back on. I imagine the banging on the bump stops rammed the strut so hard, it slipped in its housing a little? So when it is sitting on the bump stops, the front right of the vehicle sits an inch lower now. Now I reset the codes, and got the air suspension working again by replacing the relay in the back. After that, I did the turn steering wheel full left and right to reset the system. But somewhere during this process, the sensors got calibrated sitting on the bump stops with the front left being 1 inch lower. My question is, do you know what I did to trigger it to calibrate? I don't have a diagnostic tool other than the typical OBDII tool. So I couldn't have triggered the calibration on purpose.
Hi. I get the lean when cornering come on and apply the brakes. My display looks level. I have got my rear ace pipes replaced with new. I might need to replace the filter in the valve block. What do you think is causing it to come on?.
Hi dear how are you I just want to know if you can help me I have Range Rover 2005 and they take very extra excellentranslator and running is very low can you help me what will I do ?
I may add such a video if mine become worn. For the rear the process is very similar, the sensor is just in front of the air-sping and may be more difficult to get to without taking off the wheel, but otherwise it has the same 4 connection points as the front sensor. If you can find the original sensor you should still be able to get away with changing just one side and not having the car calibrated after.
Hello! I cannot calibrate the suspension, due to these errors: lateral accelerometer circuit, control module and voltage suply and something about the compressor. I just changed the block valve and the diagnose does not allow me to readjust the suspension. If you have more experience, please give an advice. Thank you in advance ;)
I have already swapped the old Height sensor to the new.. however, initially i forgot to disconnect the battery and once connected.. the suspension got phoney and only after disconnected the battery it all went back to normal.. Nevertheless, the fault sign on the panel still comes off.. dont know what to do😢
And one more question please : if I change the Suspension compresor with Aftermarket one it will work properly ? does it need to be reprogramed / coded / updated to my RRS at Land Rover or it will work without been programed/ coded/updated to my RRS ? thank you in advance.
Question, 08 sport 4.4L. Front passenger suspension goes down in normal height drive. It raises but goes back down after start. However stays up in off-road height. On the screen it displays that tire low and suspension fault and reset suspension height after obstacles are removed. Sensor replacement?
Have you seen the Amber light that blinks when you drive and then stays on when you stop? only ride height avail. R strut w bag replaces a while ago and more recently compressor replaced. Was fine after that. Now this. Suspect R F sensor. I thought I saw the r f tire on the 4x4 display glitching though now it all looks fine. Blinking error light evey time I drive now. LR4 2011 HSE
I am getting suspension fault message on my Range Rover Sport 2011 and the mid light on the level adjustment button goes off, I switch the car off and on again and everything works normally again the car level is always normal, do you know what could be wrong?
Nice job bro. Question: I have a 2013 Range Rover Sport and i found out that the rear right height sensor is faulty using diagnostic tool but when my brother buy the height sensor he got a 6pin sensor but my car equip with 3pin sensor. It is possible for me to install the 6pin sensor? Or not?
Ehhh it may be possible, but you put yourself at risk of the sensor having different voltage values than the original, which will create problems and will at the very least require a dealer calibration. I'd say just try to return the 6-pin and get an OEM sensor.
**HELP** I replaced the ride height sensor like you said, but it still is about inch lower than the other wheels but the dash says everything odd level/correct. Any idea how to get it level again? Maybe the new sensor is faulty?
Can anyone help . I have swapped my sensor and its showing it completley the opposite way around (below) the others above . Have i installed it the wrong way round .cheers .
hello, the suspension of my d Rover hse 2005 was deprogrammed, the system light that is in the center of the panel does not turn on, it is 3 orange lights. and as always the inactive suspension message. Do you have an idea of what it could be 😅 how bad I wanted to change the control arms but the suspension of my truck was totally up. Thank you
To use the Launch X431 you will need to jack the wheels up so that they are all the correct height manually, then calibrate the voltage reads from the height sensors so that they understand that that height is the preferred height. In reality, this is pretty complex and should be done at the dealer. If you want to try it yourself you may need to search for a tutorial, I have not done this job before.
Hi there , thank for your excellent videos , God bless you ! I have a question : my RRS L320 , 2008 has the same error on dashboard witch comes after I start driving and when I put the RRS on different driving modes , Access , Standard or Off Road . I see a difference of 3-4 cm in level on the right front side only , if I leave the car to stay on OFF Road mode for 2-3 days at ones without starting the car at all in all this time. The car comes up on OFF road , down on Access and Standard without any problems , only after I start driving and it feels few bumps the error its coming on the dashboard " Suspension Fault " Special Programs Off " or if I try to put the car on different driving modes wile I am in a parking . Do you have any idea what can be and I should do ? Its the sensor ? its the air pressure block valves on the front ? its the compressor ? thank you in advance !!!
Hi your video is straightforward, I just replace I just replace 2x sensor on the front left and right on Range Rover L322 2008 3.6 Diesel accidentally I damaged the connector plug Replaced the the connector plug with new one soldered Cable collect everything car was showing me error on suspension so many different messages no lights on suspension what's looking like there is no power going from the plug connector resoldered cabling everything okay I went for the drive suddenly suspension drop-down I couldn't even drive what's so bumpy , stop the car stop the car switch off switch on few timesfew times suddenly all the lights comes on suddenly all the lights comes on suspension was going up very slowly do you know what is causing the problem. Managed to go Home Jack up the car and check everything okay put the car down ,switch on the engine everything okay went for a drive back sensor error lighting read on the screen , again switch on switch off lived up and down very slowly switch off the engineswitch off the engine switch on the engine switch on the engine everything okay did you experience anything like this do you know what could be the problem I would appreciate I would appreciate if you can contact me thank you.
If you replace with an identical OEM part you do not need to recalibrate unless you notice a significant height discrepancy with manual measurements at the wheel wells. I did not recalibrate after and did not have any issues.
hey 06 LR3 here, don’t have a nav screen hoping someone can help. my front end is lower than rear and stays the same level at all times even when parked for 24+ hours. i turn the car on and it kicks compressor on and tries to raise suspension but after 15 seconds special modes and compressor kicks off and sends me the “suspension fault normal mode only” and it stays like that the whole drive. i have not found any leaks and think it’s stuck valves but not sure. sorry this was long but i’d greatly appreciate anyone who can help.
Mine shows suspension at fault and on the screen the little lines on the right tires blink red coud this be the problem?? Instead of replacing the airbags or the air compressor?? Please let me know friend
A airbag/compressor issue would have the tires ACTUALLY LOW in real life and on the screen, whereas a sensor issue would have different heights between the real-life height and what's on the screen. Consider that the height sensors are pretty cheap, and you may want to start with replacing the right sensors anyway just to see if it fixes the issue.
So i have replaced the bad height sensor in the rear. After putting the battery back, the entire rear of the vehicle completely sunk to the ground, and the front of the vehicle is completely jacked up in the air in "Extended Mode". No matter what i do with the dial, it just defaults to going right back to extended mode and is telling me to remove any obsticle that is under the vehicle. Any thoughts?
Make sure it's installed correctly (the hoses attach where they are supposed to and the electrical harness is attached), and if it isn't an OEM height sensor, it may need calibration at the dealer.
Hey bud, quick question for you. First of all thank you for the videos. They are Great! Allright maybe you can help diagnosing a problem. I've changed the air compressor, middle and front valve blocks. I can't see any leaks of the struts themself and they look pretty good. But the front passenger side is always is a bit lower than the rest, and it takes longer to inflate.. (or its just a bit lower than the other corners)... reckon the bag is due? Can't really see the hoke thing as it is protected by the metal housing. Could it be the height sensor? Bought it with a lot of issues, resolving one after another, its slowly getting great. Btw, i'ld love a rear active swaybar fix video ;)
The 2005-2009 4L or 4.4L LR3 will use the same ones as the RRS: amzn.to/3n0vgho. Just make sure to get the correct side and front/back, as they are different part #s.
@@robhill8634 Potentially poorly manufactured height sensor where the leads were reversed. I would double check the wire harness to make sure it's connected and if it is, you likely need a replacement height sensor.
Hello and hope your having a blessed day and I would like to know how to reset the suspension on 2008 Range Rover sport. I didn’t know I had to disconnect the battery before I changed out the sensors I pray you can help me with this situation thank you in advance and hope the rest of ur day is blessed
I just replaced both right height sensors but I forgot to disconnect the battery while doing it like the video said so that is why I’m asking how do I reset it because that’s what coming on dashboard now
@@mistygreen-us2tz Oh I see, try pressing the lower vehicle button in the center console. The down arrow seen in the pic: images.app.goo.gl/HMPSYmiUfVqyDMMJA
Great video. Perhaps the only one I've seen that comes close to addressing my problem. When i push the lift button it flashes twice, chimes and thats it. From the manual it says when that happens it means the command was denied. I just don't know why. Doors are closed, the height is standard looking at the screen. Just won't respond.
@@HazyJay it says "suspension lowered". Earlier today one suspension collapsed but when i restarted the car again it came back up to normal ride height but will still not respond to full lift or even lower command. Just the 2 flashes and a chime is all i get.
@@zedohh4450 I've had the issue where the front suspension would collapse but would rise again when the car was restarted, at that time it was a height sensor, what does the 4x4 info look like? Is there weird wheel movement when their shouldn't be? In lieu of that, the button chiming makes me think there's a short or even that the compressor is so warn that the system is seeing too much resistance and throws an error when you press the height change button. I changed my suspension compressor at 70k miles and 135k miles, have you changed yours yet?
@@HazyJay when i start the car the normal and lowered lights on the height switch both come on and stay on perhaps suggesting the car is at normal and lowered height at the same time?... He fault light on the cluster gauge does not come on until the car is in motion and when that happens both lights on the switch go off. The 4x4 info says "standard" and the bars are aligned but the screen says "suspension lowered" don't know what to make of it. Sorry its taken me this long to respond I've been moving to a new house.
@@zedohh4450 Both the normal and lower bar being on at the same time I believe means that the car is at normal height but in the process of lowering. The exact process that's causing the error doesn't seem obvious, if it's TRYING to lower but cant, that may indicate that there's a clog in the valve block or in the system, but honestly at that point it's not obvious enough to just start replacing things and guessing. You may consider buying a iCarSoft II scanner (or similar scanner that can read LR codes) and try to find out what is causing the fault. Or you could take it to the dealer and have them scan it while the fault is triggered. This would at least give you a stepoff point whether it be a clog, the compressor, or a height sensor. I've also seen a really bad alignment with a bent tie-rod that made it impossible to lower the car just due to the metal getting in the way.
hi friend i have lr3 hse 2008 when i i turned switch off close the driver door and lock car by remote the rear suspension tires drop down a little and i hear air sound ,does it normal in all lr3 or something issue i scan car by scanner no fault in air suspension
Hello, i have L320, after 15-20 sec i get yelow suspension fault light. And it says normal heigh only. What i saw in car. First sometimes on 4x4 screen i see bilinking "raising"-"standart" one after another. I changed relay under the hood. Suspension was working fine for 2 days. No yellow ligh, nothing. I could lift it, lower down, anything. But after 2 days light came back. Strange. If there where a bad wheel heigh sensors, in "that 2days without light" they would turn the light anyway. Car stays in normal heigh, doesnt drop. So supose no air leaks. Yesterday, i took relay away, and put back again. Rest of day was without fault light, comppresor worked fine. In the morning-yellow light again. No sensors stay in stuck possitions. What is happening?
You will likely need a new compressor, usually the OEM compressor will work for around 70,000 miles, if it's been nearly that amount since a change, it's probably this. The light will come on shortly after starting the vehicle because the compressor is straining, usually the light signifies that the reservoir is filling too slowly (because of an old compressor). Consider watching my video on this.
Thank you for your videos. I own a lr3 that is on the bump stops and those white markers over the tyres on the 4 by 4 info is flashing red . Is that ride height sensor or blown bellows of the air spring? Please advise
Unfortunately it could be many things, the MOST COMMON cause of no pressure in all 4 wheels is a faulty compressor. If you end up purchasing a new one, consider lifting the vehicle off of all 4 wheels before starting it again for the first time. When a new compressor needs to fill the entire system from zero, it sometimes overheats or needs multiple attempts, taking the weight off the wheels I predict may help somewhat with that.
Very good video. Quick question, how would I know if it’s an electrical connector problem I have rather than a height sensor one? I get the fault on the front left side. From this video and others it appears that it is a height sensor fault but I also suspect it could be the electrical connector. Is there any way of knowing from your experience?
You could visually inspect the connector for frayed wires or corrosion, but it would be difficult to predict the sensor harness is that problem otherwise. Your best bet would be to replace the height sensor and see if it resolves your issue given it's relatively cheap and easy to replace.
Help .. my 09 RR Sport 4.4L was lowering over night in front.. I left the door open overnight to check for leaks.. it did not lower w/ door ajar… but 4x4 display shows nothing abnormal .. can the still be the sensor or ???
excellent concise and clearly presented. thank you i have a 2007 RR SC and want to learn more about diagnosing and repairs NS Canada
Excellent video!! Never seen anything good as that one!!
Thank you! Every other video shows the RR on a lift for this procedure. Seeing this makes it clear I can tackle this one myself and give my wallet a break!
Your videos are awesome! Thank you! I love my RR and just want to get more years out of her.
Sir your videos are second to none. My wife has a RRS and I have subscribed. Awesome work!!!
Love your videos they are straight to the point and good video step by step
Thanks for the info I was wondering how to get that done you made it look so easy.
Eureka! The exact fault as you described; I replaced as per your video with OEM part on Tuesday and it is now back to normal! Not sure I needed the compressor the dealer scan code indicated, but hey, it's a 16 years old vehicle so cannot hurt. The original plug was a 6-pin and the new plug is a 3-pin. Thinking maybe for L/R front wheel optional placement on the original? It only had 3 wires. Thanks again.
Very well explained and short and sweet. Thanks
You are a Absolutely King 🤴 My Friend
your the best. love your videos. keep them coming for range rovers
Your videos are the best!
Hey there, I got this suspension fault light on the dash too but mine does not let me raise the level at all when I try change height to higher or lower it says "normal ride height only" suspension fault, does this still mean the suspension sensors are the problem?
Did you solve this i have the same problem
Hello, on the driver side, you show the sensor facing the fire wall, which dirección the passenger side goes, does it matter? Thank you
ibb.co/bvBMn1t
Thank you
So contrary to other videos, this looks straight forward, I did not see or hear anything about height calibration.
I would wish that this was more straight forward as you have shown .
Firstly I had an active roll fault with wiring connection to the valve block , then cleared with diagnostic , which you need really .
Then second fault with rear height sensor , I replaced this and ran guided calibration with diagnostic which would come up with an error .I then found the Active roll module was not active and needed calibrated , so not always so simple !
Thanks for the video very helpful. I want to buy a used range rover and expect to have suspension issues
For me at least:
-60k miles: air compressor ($600)
-80k miles: lower control arms, swaybar bushings ($300)
-90k miles: height sensor (just the front left one) ($60?)
-135k miles: air compressor again but I just did a coil conversion to bypass any further suspension issues for the life of the car instead of replacing the compressor ($1,300)
The suspension issues aren't too hard to fix, it's just a matter to making sure you're fixing the right part
@@HazyJay thanks!
That's so funny 😂😂😂
straight to the point. thanks.
Thank you for the video. I have an Ml320 that has a similar issue but the dash does not inform you of a problem. Instead I get different heights between the wheels and the wheel arch. And one strut deflates after exiting the car. Raising again while driving and keeping high if the motor is on. Do you think I have a height sensor problem?
I have the same problem with the 2014 Sport, it does not install under the number 3, it goes up, what is the solution? Please Help
For an LR4, the visual display is not like this. How do you know if there is a height sensor issue when there is a suspension fault warning on the console vs. a valve block issue? Car compression system works fine and stays level overnight. Thank you!
Awesome info - Thank You!
Just learning my Range Rover Sport 2012 with 150k miles. Intermittent message do not exceed 30mph suspension fault.
I have put about 5k miles on this vehicle in mixed use with no issues. Recently had compressor replaced.
Programmed correctlt supposedl by jag rover specialty shop. 250 miles later the warning shows up. 20 degrees outside. Light off next day, 25 degrees, Light on after 1 mile.
Light went off, yesterday 50 degrees out. Went for 3 hour spirited drive in mountains yesterday with no issues. Then some lite off roading. No light. Glad for that. Intermittent warning lights are so annoying!
Temperature-related warnings sometimes are due to a low battery. The sensors are really finicky, and a battery just 2 years old can start causing issues. I use a AGM battery and found these are the best and haven't had issues in years. Just something to consider!
Ace video👍
I have my front offside circa 20 mm lower than near side but no fault shown on dash
You will likely need calibration on a leveled surface at the dealer unfortunately =(
Excellent video God bless you!!
Thank you. Excelent video
Hi great video, I take you don’t have to calibrate after the new one is fitted
As long as you replace the sensor with the same one that was removed it should be OK. If you note obvious height differences with a measuring tape then you may need to.
hi, my LR4 , 2014, front has dropped. Air springs have no leak, the valve block is ok. But the vehicle is not lifting (in front). The compressor is working fine as well. What could be the issue? Thanks
Hi, Hazy! Always love your very detailed tutorials. Thank you!
I would get occasional rear sag that would automaticall correct upon start. I would also get random suspention fault warnings.
The truck gave a teriibly rough ride over bumps too.
About a month ago I replaces the compressor and I just replaced my rear airsprings 2011 RRS HSE and all was fine. It raised up and lowered no problem right after both replacements.
After a good test drive with no warnings I figured raise and lower it again for another test...
Well, Its stuck up in off road height now and won't let me lower it. Says suspension fault then the usual dont drive over 35mph, etc...
I've tried turn off and on numerous times and still no change. Seems the system will not deflate. As soon as I hit the button to lower it sends a suspention fault warning. Absolutley nothing happens. No air comes out, no movement at all... suspension controls just shut down.
Even right after startup it will immediately go to fault as soon as I hit the button and try to adjust height to normal.
Maybe theres a clog after all the work I did?
If you have any ideas, I would be very grateful if you shared.
Thanks in advance and thanks again for your great vids!
All 4x4 dash info looks even and steady, its just stuck in off road height.
When working properly the system fills and raises fast... just for whatever reason right now I cannot get it to go down.
Will disconnecting the.battery help? Or do you think this is a height sensor?
Or a clog?
Help!?? Please?
Thank you!
Hmmm it's likely the error is caused by the gallery (air springs) lowering too slowly making the vehicle think there is an obstruction, which then causes it to jump up to extended mode. This would trigger code C1A13-64 Pressure does not decrease when venting gallery. So it's potentially a clog which can usually be fixed by cleaning out the desiccant chamber on the compressor or replacing the exhaust valve. I'd make sure you're having the C1A13 error though first, consider using a code tool to check or have a dealer check.
@@HazyJay Thanks for the speedy reply! Your the best!
I have a basic OBD2 scanner and show no codes. I was actually looking for the one you mentioned.(saw it in the comments and on RR threads)
I understand what you are saying about the suspension thinking obstruction below truck and shooting into extended mode.., but thats not happening.
From past experience, typically if something is under the truck I am promted before lowering and that doesn't happen now. It doesn't put itself in extended mode either. I put it into off road height myself(purposely) and now it will not go down. Thats pretty much it.
The 4x4 screen shows the suspention at level in off road height(as it should), but it won't move. Its just stuck there.
When I start the truck; the dash display says normal height and the center console height selector switch has the off road height and the center normal ride height symbols lit up, yet no suspension fault in the dash display.
At this point I try to lower the suspension and as soon as I touch the height selection button I imediately get the suspension fault and get locked out of the suspension controls. The truck stays in off road height... doesn't change at all. No compressor noise, no air release noises, nothing but the ding and the fault from the dash display.
Im not sure its a height sensor as when viewing the 4c4 display all 4 wheels register the proper postion in accordance to the trucks actual height.
Could it be a bad relay?
Or possibly the exhaust valve? The compressor is only a month old.(bought new).
I am truly grateful for you responding and doing what you can to help.
I hate to be a bother.... but I do anxiously look forward to your next reply.
Your insight is much appreciated.
Thank you, Hazy!
I think a bad relay or fuse is more likely, or a burned out ECU, given it errors as soon as you press the button and doesn't even attempt to change heights. I'd check the fuses/relays first since it's cheap/easy, but if they're normal then you'll need someone with a Jaguar/LR diagnostic tool to check and see what exactly is causing the system failure. I hate going to the dealer but that should be a cheap/free diagnostic test, then you can fix it yourself most likely.@@kevinfelisberto4204
@@HazyJay WOW! I wish I could get answers that fast from any local shop or even Google! Thats awesome... Thank you!
I will definitely look into the relay/fuses. I did see someone suggest replacing the relay when you do the airsprings as that would be as old and tired as the springs themselves and may not be up to par with the new setup.
And as you suggest, if that isn't it then I will have the ECU checked out.
I will repost when/if I get this figured out. Lol, I may end up with another question first.🤷♂️
Thanks again for your help! You are a great service to all of us RR aficionados.
A true gentleman. 😎👍
@@kevinfelisberto4204 No problem I hope you figure it out, let me know if you do and what it was, I'm hoping it's something easy/cheap. 👌👌
hi when carrying out this repair do you need to program the sensor into he car and set ride height or is it plug and play thanks
If you replace with the identical part you don't really need to calibrate, if you ask the dealer they will say you need to calibrate it
@@HazyJay thanks for the quick response, you seem like the only guy on youtube that simply explains the fault and causes and how to fix simply. very basic and straight forward thanks again
Thank you for the video. My screen shows the car is rising but it actually isnt. The lights on the switch will light up but go out and a fault will present. Secondly once or twice a week it will work fine without notice. I am having trouble finding a shop that will work on it. Any suggestions? Thanks Re:2006 full size Range Rover
Whoa thanks for sharing. Just got one of these. Do you know other reasons to look out for Suspesion faults? For example, you mentioned either the compressor or valve blockage. Would it display on dashboard for those specific errors??
Disconnecting the NEGATIVE terminal is ideal in practice (as to minimize chances of shorting out by contact of the POSITIVE terminal to the vehicle’s chassis)
I have a 2006 rrs supercharged... My car was fine and out of boredom i selected calibrate anti roll option then i got e 7 error code and my red suspension light is on... Everything still works ie suspension goes up an down etc but now the red light stays on and fault code C 1 A00-54 - Control module - System programming failure - missing calibration (AB)... 😮... Any advice please 🙏
Thank you sir! Why is my RRS bent over to the left side ? My lines are not in place. I have tried many ways
I replaced rear driver side it looks exactly likr the one you replaced in front. Are all 4 sensors the same?
Hi Hizy. My Range Rover hse 2007 is alway show the (front passenger) suspension not stable ( some time that turn normal height,but sometimes it show very low ) also I cannot rise and lower it by control and my special program are also no light at the control and also not able to control because it said special program off. Last night I park it the front rear look normal stable but my driving backside rear drop down very low! Can you give me some advice?
Do they have to be recalibrated or just plug and play?
Great vid .
I have same light on my dash but says .
Vehicle leanwhen cornering .
Will this be the same height sensor to sort out problem please ?
Brilliantly done
Hi, my range is in high extended mode, how can i cancel this back to standard. Mode? Thanks
On my 2006 lr3 is blinking on indicating the rear I changed the air suspension but still not raising up
What about if there is nothing wrong with the dots on the 4x4 screen but it changes from standard to raising real quick
I have a 2006 lr3 and when I drive it it won’t let me go over 30 mph as if it lost power. But when I let off gas it picks up power until gets to going over 30 mph then it does it again. Please help.
Awesome video. Im running an Lr3 and have just had new blocks front and rear changed. Truck drops down to bump stops overnight... have checked entire system for leaks now. Put it into extended height, removed Fuse 26, and for the first time in 2 years it stayed up. Did the same again in normal height 3 days ago and truck remains up... no warning lights on normally could this be a faulty height sensor... ? I should say the truck drops on all 4 corners not bias to one corner... cheers
Definitely doesn't sound like a leak, system is probably trying to level over and over while it's parked, I'm under the impression it can only DROP and can't RAISE while the car is off. I'd suspect one of the height sensors is off, what does the 4x4 info say though? Do all wheels look level and stable?
Whats fuse 26 solve i have this issue
I did change the passenger side sensor. The screen on the dash , indicates all OK. Yet, the suspension light, keep coming back after few minutes of driving?
What I am missing?
Thank you
Awesome short and detailed Vid mate, cheers from OZ. Mine randomly says 'Suspension Fault' only when putting it in raised height and doesn't always appear.. Replaced the Compressor recently. and all 4 wheel sensors appear to be normal. Any Ideas on what the fault for raised height is? Is there a Single sensor or ''Brain'' that all 4 go to? Cheers.
There is a control unit but if it was faulty, you would likely have more severe issues. I'd consider raising the vehicle while watching the 4x4 screen, sometimes the height sensors will start to send weird signals at certain heights and maybe you can catch which one is faulty.
Don't know if you have any insight, but when I got my 06 RR SC, it was on its bump stops. Someone had driven it like that and the front right strut, if you pull the rubber cap off under the hood, sits 1 inch higher than the left one. So much that the cap won't go all the way back on. I imagine the banging on the bump stops rammed the strut so hard, it slipped in its housing a little? So when it is sitting on the bump stops, the front right of the vehicle sits an inch lower now. Now I reset the codes, and got the air suspension working again by replacing the relay in the back. After that, I did the turn steering wheel full left and right to reset the system. But somewhere during this process, the sensors got calibrated sitting on the bump stops with the front left being 1 inch lower. My question is, do you know what I did to trigger it to calibrate? I don't have a diagnostic tool other than the typical OBDII tool. So I couldn't have triggered the calibration on purpose.
Hi. I get the lean when cornering come on and apply the brakes. My display looks level. I have got my rear ace pipes replaced with new. I might need to replace the filter in the valve block. What do you think is causing it to come on?.
Hi dear how are you I just want to know if you can help me I have Range Rover 2005 and they take very extra excellentranslator and running is very low can you help me what will I do ?
Hi I’ve replaced the height sensor but still not fixed. What else can be causing this?
I replaced my rear air suspension strut ,it's work well whe the engine is turn but when I turn of over night it's already too low.is it normal.
Very supeeeeeer video....I have range rover sport 4.2SC....please.....replace rear height sensor...
I may add such a video if mine become worn. For the rear the process is very similar, the sensor is just in front of the air-sping and may be more difficult to get to without taking off the wheel, but otherwise it has the same 4 connection points as the front sensor. If you can find the original sensor you should still be able to get away with changing just one side and not having the car calibrated after.
Hello! I cannot calibrate the suspension, due to these errors: lateral accelerometer circuit, control module and voltage suply and something about the compressor. I just changed the block valve and the diagnose does not allow me to readjust the suspension. If you have more experience, please give an advice. Thank you in advance ;)
Thanks for video,any suggestions where to buy sensors from,any luck with Amazon sensors.
I have already swapped the old Height sensor to the new.. however, initially i forgot to disconnect the battery and once connected.. the suspension got phoney and only after disconnected the battery it all went back to normal..
Nevertheless, the fault sign on the panel still comes off.. dont know what to do😢
And one more question please : if I change the Suspension compresor with Aftermarket one it will work properly ? does it need to be reprogramed / coded / updated to my RRS at Land Rover or it will work without been programed/ coded/updated to my RRS ? thank you in advance.
Question, 08 sport 4.4L. Front passenger suspension goes down in normal height drive. It raises but goes back down after start. However stays up in off-road height. On the screen it displays that tire low and suspension fault and reset suspension height after obstacles are removed. Sensor replacement?
Have you seen the Amber light that blinks when you drive and then stays on when you stop? only ride height avail. R strut w bag replaces a while ago and more recently compressor replaced. Was fine after that. Now this. Suspect R F sensor. I thought I saw the r f tire on the 4x4 display glitching though now it all looks fine. Blinking error light evey time I drive now. LR4 2011 HSE
I am getting suspension fault message on my Range Rover Sport 2011 and the mid light on the level adjustment button goes off, I switch the car off and on again and everything works normally again the car level is always normal, do you know what could be wrong?
Nice job bro. Question: I have a 2013 Range Rover Sport and i found out that the rear right height sensor is faulty using diagnostic tool but when my brother buy the height sensor he got a 6pin sensor but my car equip with 3pin sensor. It is possible for me to install the 6pin sensor? Or not?
Ehhh it may be possible, but you put yourself at risk of the sensor having different voltage values than the original, which will create problems and will at the very least require a dealer calibration. I'd say just try to return the 6-pin and get an OEM sensor.
**HELP**
I replaced the ride height sensor like you said, but it still is about inch lower than the other wheels but the dash says everything odd level/correct. Any idea how to get it level again? Maybe the new sensor is faulty?
Can anyone help . I have swapped my sensor and its showing it completley the opposite way around (below) the others above . Have i installed it the wrong way round .cheers .
Great Video! Thank you
Hello, I had some problems. My LR3 goes on extended mode by itself and doesn't lower down while driving up to 35
hello, the suspension of my d Rover hse 2005 was deprogrammed, the system light that is in the center of the panel does not turn on, it is 3 orange lights. and as always the inactive suspension message. Do you have an idea of what it could be 😅 how bad I wanted to change the control arms but the suspension of my truck was totally up. Thank you
Hi I got 2007 range rover sport I change the transmission modular but still I have the same problem do I have to change the sensor ?
Please teach me. Launch calibration suspension X431 Range Rover 2004
To use the Launch X431 you will need to jack the wheels up so that they are all the correct height manually, then calibrate the voltage reads from the height sensors so that they understand that that height is the preferred height. In reality, this is pretty complex and should be done at the dealer. If you want to try it yourself you may need to search for a tutorial, I have not done this job before.
Hi there , thank for your excellent videos , God bless you ! I have a question : my RRS L320 , 2008 has the same error on dashboard witch comes after I start driving and when I put the RRS on different driving modes , Access , Standard or Off Road .
I see a difference of 3-4 cm in level on the right front side only , if I leave the car to stay on OFF Road mode for 2-3 days at ones without starting the car at all in all this time.
The car comes up on OFF road , down on Access and Standard without any problems , only after I start driving and it feels few bumps the error its coming on the dashboard " Suspension Fault " Special Programs Off " or if I try to put the car on different driving modes wile I am in a parking . Do you have any idea what can be and I should do ? Its the sensor ? its the air pressure block valves on the front ? its the compressor ? thank you in advance !!!
Hi your video is straightforward, I just replace I just replace 2x sensor on the front left and right on Range Rover L322 2008 3.6 Diesel accidentally I damaged the connector plug
Replaced the the connector plug with new one soldered Cable collect everything car was showing me error on suspension so many different messages no lights on suspension what's looking like there is no power going from the plug connector resoldered cabling everything okay I went for the drive suddenly suspension drop-down I couldn't even drive what's so bumpy , stop the car stop the car switch off switch on few timesfew times suddenly all the lights comes on suddenly all the lights comes on suspension was going up very slowly do you know what is causing the problem. Managed to go Home Jack up the car and check everything okay put the car down ,switch on the engine everything okay went for a drive back sensor error lighting read on the screen , again switch on switch off lived up and down very slowly switch off the engineswitch off the engine switch on the engine switch on the engine everything okay did you experience anything like this do you know what could be the problem I would appreciate I would appreciate if you can contact me thank you.
Could you please show me the passenger side sensor height position. I did removed and forgot to mark it. Thank you.
Don’t forget to add to This vidoe that you do need to program sensores after installing
If you replace with an identical OEM part you do not need to recalibrate unless you notice a significant height discrepancy with manual measurements at the wheel wells. I did not recalibrate after and did not have any issues.
My compressor works well one or two days then not the next. The fault is always showing on the dashboard. Could this be the relay
Hi I changed my ride sensor which was showing red when lowered but it hasn't solved the problem. I still get the yellow suspension light. Thanks
Thankyou sir!
hey 06 LR3 here, don’t have a nav screen hoping someone can help.
my front end is lower than rear and stays the same level at all times even when parked for 24+ hours. i turn the car on and it kicks compressor on and tries to raise suspension but after 15 seconds special modes and compressor kicks off and sends me the “suspension fault normal mode only” and it stays like that the whole drive. i have not found any leaks and think it’s stuck valves but not sure.
sorry this was long but i’d greatly appreciate anyone who can help.
Mine shows suspension at fault and on the screen the little lines on the right tires blink red coud this be the problem?? Instead of replacing the airbags or the air compressor?? Please let me know friend
A airbag/compressor issue would have the tires ACTUALLY LOW in real life and on the screen, whereas a sensor issue would have different heights between the real-life height and what's on the screen. Consider that the height sensors are pretty cheap, and you may want to start with replacing the right sensors anyway just to see if it fixes the issue.
So i have replaced the bad height sensor in the rear. After putting the battery back, the entire rear of the vehicle completely sunk to the ground, and the front of the vehicle is completely jacked up in the air in "Extended Mode". No matter what i do with the dial, it just defaults to going right back to extended mode and is telling me to remove any obsticle that is under the vehicle. Any thoughts?
Make sure it's installed correctly (the hoses attach where they are supposed to and the electrical harness is attached), and if it isn't an OEM height sensor, it may need calibration at the dealer.
Hey bud, quick question for you.
First of all thank you for the videos. They are Great!
Allright maybe you can help diagnosing a problem.
I've changed the air compressor, middle and front valve blocks. I can't see any leaks of the struts themself and they look pretty good. But the front passenger side is always is a bit lower than the rest, and it takes longer to inflate.. (or its just a bit lower than the other corners)... reckon the bag is due?
Can't really see the hoke thing as it is protected by the metal housing. Could it be the height sensor?
Bought it with a lot of issues, resolving one after another, its slowly getting great.
Btw, i'ld love a rear active swaybar fix video ;)
Did u fix it buddy i have the same problem and mot failure

The 2005-2009 4L or 4.4L LR3 will use the same ones as the RRS: amzn.to/3n0vgho. Just make sure to get the correct side and front/back, as they are different part #s.

Hello and hope your having a blessed day and I would like to know how to reset the suspension on 2008 Range Rover sport. I didn’t know I had to disconnect the battery before I changed out the sensors I pray you can help me with this situation thank you in advance and hope the rest of ur day is blessed
Try disconnecting the battery overnight and reconnecting in the morning. What symptoms are you having?
@@HazyJay it’s saying I need to reset suspension
I just replaced both right height sensors but I forgot to disconnect the battery while doing it like the video said so that is why I’m asking how do I reset it because that’s what coming on dashboard now
@@mistygreen-us2tz Oh I see, try pressing the lower vehicle button in the center console. The down arrow seen in the pic: images.app.goo.gl/HMPSYmiUfVqyDMMJA
@@HazyJay ok I'm going to try that and I will let you know if that works and thank you for your help
Great video. Perhaps the only one I've seen that comes close to addressing my problem. When i push the lift button it flashes twice, chimes and thats it. From the manual it says when that happens it means the command was denied. I just don't know why. Doors are closed, the height is standard looking at the screen. Just won't respond.
I would check the air suspension relay under the hood first to make sure it isn't flipped, is there any message on the dash like "Normal height only"?
@@HazyJay it says "suspension lowered". Earlier today one suspension collapsed but when i restarted the car again it came back up to normal ride height but will still not respond to full lift or even lower command. Just the 2 flashes and a chime is all i get.
@@zedohh4450 I've had the issue where the front suspension would collapse but would rise again when the car was restarted, at that time it was a height sensor, what does the 4x4 info look like? Is there weird wheel movement when their shouldn't be? In lieu of that, the button chiming makes me think there's a short or even that the compressor is so warn that the system is seeing too much resistance and throws an error when you press the height change button. I changed my suspension compressor at 70k miles and 135k miles, have you changed yours yet?
@@HazyJay when i start the car the normal and lowered lights on the height switch both come on and stay on perhaps suggesting the car is at normal and lowered height at the same time?... He fault light on the cluster gauge does not come on until the car is in motion and when that happens both lights on the switch go off. The 4x4 info says "standard" and the bars are aligned but the screen says "suspension lowered" don't know what to make of it. Sorry its taken me this long to respond I've been moving to a new house.
@@zedohh4450 Both the normal and lower bar being on at the same time I believe means that the car is at normal height but in the process of lowering. The exact process that's causing the error doesn't seem obvious, if it's TRYING to lower but cant, that may indicate that there's a clog in the valve block or in the system, but honestly at that point it's not obvious enough to just start replacing things and guessing. You may consider buying a iCarSoft II scanner (or similar scanner that can read LR codes) and try to find out what is causing the fault. Or you could take it to the dealer and have them scan it while the fault is triggered. This would at least give you a stepoff point whether it be a clog, the compressor, or a height sensor. I've also seen a really bad alignment with a bent tie-rod that made it impossible to lower the car just due to the metal getting in the way.
suspension stop raising , suddenly, it shows raising slowly. Suspension raise when system cools down. car is parked but still not working.
hi friend i have lr3 hse 2008 when i i turned switch off close the driver door and lock car by remote the rear suspension tires drop down a little and i hear air sound ,does it normal in all lr3 or something issue i scan car by scanner no fault in air suspension
Yeah it will do that on it's own, that's normal 👍

Bravo great video
Hello, i have L320, after 15-20 sec i get yelow suspension fault light. And it says normal heigh only. What i saw in car.
First sometimes on 4x4 screen i see bilinking "raising"-"standart" one after another. I changed relay under the hood. Suspension was working fine for 2 days. No yellow ligh, nothing. I could lift it, lower down, anything. But after 2 days light came back. Strange. If there where a bad wheel heigh sensors, in "that 2days without light" they would turn the light anyway. Car stays in normal heigh, doesnt drop. So supose no air leaks. Yesterday, i took relay away, and put back again. Rest of day was without fault light, comppresor worked fine. In the morning-yellow light again. No sensors stay in stuck possitions. What is happening?
You will likely need a new compressor, usually the OEM compressor will work for around 70,000 miles, if it's been nearly that amount since a change, it's probably this. The light will come on shortly after starting the vehicle because the compressor is straining, usually the light signifies that the reservoir is filling too slowly (because of an old compressor). Consider watching my video on this.
Thank you for your videos. I own a lr3 that is on the bump stops and those white markers over the tyres on the 4 by 4 info is flashing red . Is that ride height sensor or blown bellows of the air spring? Please advise
Unfortunately it could be many things, the MOST COMMON cause of no pressure in all 4 wheels is a faulty compressor. If you end up purchasing a new one, consider lifting the vehicle off of all 4 wheels before starting it again for the first time. When a new compressor needs to fill the entire system from zero, it sometimes overheats or needs multiple attempts, taking the weight off the wheels I predict may help somewhat with that.
Very good video. Quick question, how would I know if it’s an electrical connector problem I have rather than a height sensor one? I get the fault on the front left side. From this video and others it appears that it is a height sensor fault but I also suspect it could be the electrical connector. Is there any way of knowing from your experience?
You could visually inspect the connector for frayed wires or corrosion, but it would be difficult to predict the sensor harness is that problem otherwise. Your best bet would be to replace the height sensor and see if it resolves your issue given it's relatively cheap and easy to replace.
@@HazyJay Fantastic, thanks. I’ll try that as a starting point.
Help .. my 09 RR Sport 4.4L was lowering over night in front.. I left the door open overnight to check for leaks.. it did not lower w/ door ajar… but 4x4 display shows nothing abnormal .. can the still be the sensor or ???
If you park on an incline it will make the front lower, a way to check this is to back in, in the back now lowers, it's because of the incline.
