Twice in the last week I noticed that my RRS was leaning toward the front passenger side (in the morning). The front passenger side was as low as "access mode" while the rest of the vehicle was a normal height... When I started it up, everything evened out...

Couple things to note: it was in snow mode both times and has happened twice (both times in the morning). Also, everything else is running perfect (as far as I can tell).

Any idea of what is going on?

Have you checked for bag leaks?

I havent... How exactly would I do that?

Re: air suspension, RRS leaning, something weird is going on...

i would do the soapy water technique

Re: air suspension, RRS leaning, something weird is going on...

So the car sat for 12 hours last night and the passenger side front corner did not go down any. Only difference was that I took it out of snow mode and had it in regular... Maybe it could have been a fluke? I am going to keep watching it. This morning I took it to the car wash to have all the salt/dirt removed (also cleaning out the wheel wells), they dried it pretty well before leaving the wash and my garage is heated... Otherwise I wouldn't have washed it with a sub-zero temp this morning.

Open to any ideas...

This was a common problem on the P38 forum. Either a leaking bag, a crack or pin hole in the plastic air line or leaking connection (o-rings) at the pump. Driving mode should have nothing to do with this. Temperature might. If the air system is like the P38, the hoses are pressed into the valve block at the pump and sealed with o-rings. These sometimes need replacing. Mine went bad at 125,000 miles on my P38. Easy to replace. I pulled one, measured it and then bought a set from McMaster Carr for less than $10.00. Replacement took less than 10 minutes but the pump was on the firewall up high and easy to get to. I have not investigated where it is on the RRS.
Airbag replacement is not that hard either. Some people had a problem where the air line went into the bag. Put some soapy water on the fittings to see if they are leaking.
Good luck. Air suspension need more service than coil springs. Many P38 owners changed over to coils. I can see that happening in the future for RRS's.

Only if they make 'em with a 2" lift. :wink:

Re: air suspension, RRS leaning, something weird is going on...

Another day and no leaning/leaking going on... I wonder why it was just those two times? Still watching it...

Ninjas have been coming in and letting the air out. You can't see them because they're ninjas.

The one universal truth to my RRS (08) is that there are numerous electronic gremlins; none of which ever appear when at the dealership.

Re: air suspension, RRS leaning, something weird is going on...

Ninjas or gremlins? Don't say both!

Re: air suspension, RRS leaning, something weird is going on...

You mentioned snow in other words it was cold, its possible a valve got stuck and might be tempreture related

Re: air suspension, RRS leaning, something weird is going on...

sounds like a valve or a bag.

**** impossible to see with soapy water. The only way is to hook up IDS and know what the hell you are doing. Just because one side goes down doesn't mean thats the valve that is bad.

On my recently acquired 2011 Range Rover Sport SC with 21k miles, noticed this same thing. Overnight most times (but not all) in the garage I'll come out in the morning and the truck def has a lean towards the drivers side rear wheel. As soon as I start the truck she evens out.

While at the shop today for routine inspection I mentioned it to the service advisor. They inspected/checked for any fault codes but found nothing. Offered to keep the Range overnight/couple of days to see if it does it there. Didnt have time to leave it this time, but assuming this keeps happening I'll take her in and leave it for them to check out longer term.

Thought I'd share details of my note to the local dealership. Plan to drop it off and leave it overnight/couple of days so they can reproduce the issue/properly diagnose/resolve.

after sitting overnight in (new) garage with level concrete floor, the Range Rover develops a noticeable lean towards driver side. Upon re-starting the engine, the air suspension lifts and truck levels out fine. Following are notes: After sitting overnight the distance from garage floor to underside of center section of side marker fender lights: Driver side 34 and 10/16th inches. Passenger Side 35 and 13/16th inches. The distance from garage floor to underside of center of rear door handle: 38 and 1/2 inches passenger side. 37 inches drivers side. After starting the engine and shutting engine off then measuring within 5 minutes the distances are: distance from garage floor tounderside of center section of side marker fender light: Driver side 36 and 7/16th inches. Passenger Side 36 and 4/16th inches. Distance from garage floor to underside of center of rear door handle: Driver side 38.5 inches. Passenger side 38 and 7/16 inches. In addition I randomly have heard slight "whirring" electrical motor type noise emanating from drivers side rear wheel area with truck off/when Im working in the garage.

Re: air suspension, RRS leaning, something weird is going on...

First thing that springs to mind is that you are measuring entirely incorrectly. All suspension measurements are taken from wheel centre to fender lip. This eliminates differences in tyre pressure, wear, sizing, wheel differences and uneven ground.

Well actually there is a long convoluted way to measure that involves measuring from some bump on part A up to some notch in part B at XX degrees Centigrade when the full moon lands on a day beginning with the letter T. I don;t know of a single shop that actually follows it on newer rigs though.

Re: air suspension, RRS leaning, something weird is going on...

Thanks and point taken.

However, when we compare the relative settings (sitting overnight to sitting 5 mins post shut down) to one another, seems obvious (at least to me) that something..is wrong.

 

[RRToadHall]

Re: air suspension, RRS leaning, something weird is going on...

Oh something is definately wrong. Hopefully easy as a leaking cross over valve. I'm just sayin the shop is goinna look at your measurements and be starting from scratch so they have something more accurate to work with.

Re: air suspension, RRS leaning, something weird is going on...

thanks much for your info. Im new to Rovers (and Trucks..and air suspensions) so it's all quite helpful.

Question. When I pull into my garage I'm assuming I'm in the "normal" height mode. (I rarely if ever press down on the button to go into access/crawl mode.) That said, is it normal for the truck to visibily and noticeable raise up the next day after starting? Or is that definitely one of the symptoms of a air suspension issue?

Thanks again

Re: air suspension, RRS leaning, something weird is going on...

Been at the dealership for two days. (no problems with that..I told them to take their time with a focus on getting it resolved properly vs rushing it back to me). After sittiing overnight the tech did confirm the truck leans to drivers side after sitting overnight/after "x" amount of hours. THey wanted to disconnect the battery (not 100% sure why, but thats fine) and do more testing. They did and also "sprayed down various air suspension related components" and did not find anything leaking, but did determine that its the drivers side front corner thats lowering overnight. They are doing more testing today but per Land Rover their next step is to focus on a "cross link valve" to determine if it is functioning within spec or not. They plan to keep it again overnight tonight and through the day tomorrow, which is fall fine with me.

Did you hear back from LR on this issue? I have the same issue with my rig. Do let me know what they tell you.

Thanks!
