suspension fault lr3

got new cooper zeons put on and 3 days later get the suspension fault display and amber light. it says must remain in normal mode.


the compressor cover does not look cracked or damaged in any way from the shop installing the tires. the truck is 2007 with 85k miles and I am original owner. the compressor will raise and lower the truck initially. The message and light coming on once you begin driving. The compressor may have been running more lately but my wife cannot be sure.


Anyone willing to give an opinion how to proceed?
Do I go to dealer to get codes read?( I do not want a large repair bill if I can help it).


Do I attempt to replace the compressor empirically given age and mileage of truck? Is this a difficult job?


Does the dealer need to reset things if the compressor is replaced empirically?


Thanks for any input.

Sounds like the compressor is going, given the miles and the fact that you are probably dealing with more humidity now than normal that's not terribly surprising. You could rebuild the hitachi or just replace with the AMK unit. (or if you want to go nuclear, replace with coils).

If you do the rebuild I don't think you need to reset, AMK requires re-flash.

I think that the correlation between the tires and fault light are purely coincidental. I do not believe that your new tires are causing a suspension fault. I agree with Ray. If you are on the original hitachi, then you were on borrowed time as it was. I replaced the hitachi in my 2006 at 75k miles and again at 150k. I highly recommend you do the AMK if you plan on keeping it. It is easy enough as Ive done them in under 30 minutes. I have the full Genuine kits for $740/delivered if you need one. I include instructions as well. Reflash is generally required, but I have seen a few be installed without needing it. There is no rhyme or reason to these things.

I did the rebuild to include desiccant,springs, o rings. This did not fix the problem. After a 15 minute drive, the amber light and fault code stating normal height only returned.

Does anyone know if the code has to be cleared at the dealer in order for the rebuild to work??

How to proceed? Unplugging battery help in any way?

Thanks for any advice

Paul-
You can see if a hard reset fixes the codes, a lot of times there are 'ghosts' in the system of residual codes. (google it, but the basic version is to detach positive/negative cables, join them with a long screwdriver or something, and let it sit for ~10min)

This is why I think an IID tool is pretty much mandatory if you want to do anything substantive with the truck. It's a great investment and Lucky 8 can take care of you there.

Interesting, the same exact problem started happening with my 2008 LR3 2 weeks ago. Starts off fine but within 2 minutes the amber light comes on and says normal height only. Before the light comes on I can raise and lower the truck and it drives fine after the light comes on. I used my Faultmate to pull the codes and it says:


U0421-Invalid Data Received From Suspension Control Module


I clear it but it comes right back.

Unfortunately if your compressor was beyond the point of no return, the rebuild is fruitless.

The compressor on our 2005 went at around 85,000 too. Just did a complete replacement. Eric is right. Sounds like yours was at the same point.

suspension compressor lr3

after rebuilding the compressor with no luck, I am thinking a new compressor is the next step.

amazon has an off brand compressor by the name of APDTY 050011 that is around 250 dollars cheaper than hitachi. Anyone with experience with this compressor? Do you get what you pay for or is this a good direction to go in?

Based on the photos, it LOOKS like a hitachi compressor. I'd be tempted to use that, it's the best price I've seen for a compressor.

Paul, I had the same symptoms on my 06 LR3 HSE. I, too, changed the desiccant and it did not make squat of a difference. However, when I changed the piston arm seal, that did the trick. If you were able to change the desiccant; changing the piston arm is easy and worth it before chucking out the compressor. Mind you, all these shenanigans occurred smack dab at 60000 miles.Also, check to make sure there are no leaks around the quick connect tubes.

You need to go to a dealership or Rover specialist to have to fault codes read. There are so many things that could be causing the fault, its silly to just throw parts at it.

Odd question but are the Coopers standard or oversized?

what Jimmie said....
I don't know the exact number, but I have fitted dozens of AMK compressors to fix mysterious happenings with RLC on the LR3's. that being said, I'm at 140k on my original Hitachi.....
Another option if one wanted to replace the compressor- Dunlop offers a drop in replacement for the Hitachi that wont require a re-flash.

I just returned this compressor to Amazon. I'm having the same issue and decided to try the cheap route too... I figured with Amazon Prime I could return it if it doesn't fix the issue. It's a direct replacement, but it's loud as anything (noise generally doesn't bother me, but this is noticeable) and after a minute of running it sputters a bit and then I get a suspension fault.. so it didn't fix the issue.

Is this the go to piston seal kit that everyone uses? Also, what is the best place for the desiccant?

I believe you can use any desiccant in theory. Personally, I got my kit from Kieran. Bloke sent me an extra piston ring for free when I buggered it. It has all the replaceable components. If this doesn't work, your best off replacing the entire contraption. They sell cheaper kits, with the desiccant only as well.

Thanks, that helps. Just located the same kit on eBay from what appears to be a LR dealer. $71 shipped.
06' with 68k on the odo and the air system appears to be working fine (knocking on wood right now....). Should I go ahead and do the rebuild now (rings and desiccant) or wait until an issue presents itself?

Quite frankly, its a b***H to take out the compressor; there's a hidden bolt. Additionally, the plastic tubes that feed into the compressor are usually melted on to the fittings due to age and also are another weak point while removing the part. I cut the tubes in a straight section and went for quick connect fittings. If you ever need the exact sizes, let me know, I have them somewhere.

Given the above, I'd just wait for the problem to present to attempt a repair. FWIW, I never used the suspension control and yanked the fuse in Engine Bay to deactivate the system in Normal height mode.
