Hi all, My 2008 LR3 will change it's ride height while standing still at a stop light on pretty level ground. Is this normal? You can actually see the front end raise up. I have to be paying attention and usually don't notice it but my wife feels/see's it everytime and asks me what's going on? I'm not sure?

 

Here's a section on the vehicle dynamic suspension from the shop manual. That system has lots of sensors, a brain of its own, and the potential to do what it wants when it wants to, even with engine off. Most likely will take a dealer or super shop computer to diagnose if it is a problem. If it is making changes on its own, many times these have a light or message that is displayed.

With most air suspensions small leaks can be found with a spray bottle of soapy water, it makes bigger and more bubbles when you are at the leak. Perhaps something leaks more when you brake for that stop light.

 

My 2006 also does that. It kinda freaks me out. lol I only notice it when the vehicle is not level. Seems to be leveling itself??

 

Thanks for the replies, I'll just run it for now and get it to the dealer once we are back in the States. We are in Mexico with it right now until April. Other than the slight raising at lights it functions fine and no errors.
My concern is because before we left to drive down here my wife noticed this then within a few weeks we got a suspension fault and the air suspension lowered to access height going down the hwy. We ended up with new ride height sensors and a compressor.
Even so, I do agree this thing has a mind of it's own and is constantly leveling itself so I'm not too worried yet.
Thanks again,

I recently started experiencing random adjustments along with "suspension fault" indicator while my LR3 is stationary. It had been a while since I'd taken her into the dealership for her oil changes and routine stuff - avoiding the outrageous service prices for basic stuff - so I figured I'd take her in. I was told this (among several other issues as well) was a faulty front-driver's-side suspension height sensor and quoted $500+ to replace the sensor and re-calibrate. This seemed really expensive so I opted not to have it done at that time and decided to research it a bit more on my own.
With a little Googling I found the sensor online for $47 and it seems like a simple repair. Looking through this thread I saw Savannah Buzz's post with the documents attached.

So my two questions are:
#1 - How critical is the calibration (is this just a good-to-do in order to be thorough or will the suspension malfunction or ride funny without it)?

#2 - Can the calibration be done self-serve (or at least at a non Land Rover service shop)? What is the "T4" specified in those documents? ...or am I screwed and have to pay the god-awful local dealer to do this?

 

From what I was told, It must be calibrated or will drive very crappy and might throw warnings.

I am going to buy the Gap Diagnostics tool (EAS Control) This little bugger lets you raise and lower the LR3 to accommodate larger tires and such. It also allows you to find problems within the air system. But for you, here is the best thing. It calibrates the truck as well.. You will have to measure heights at all corners and program them in. It plugs into the diagnostic port under the steering wheel and lets you use the cruise control buttons to navigate. :-) Lucky 8 has them for $399.00

EAS Control is strictly for adjusting and calibrating / troubleshooting air suspensions

 

I can't find the Gap Diagnostics tool on the Lucky 8 site (lucky8llc.com?), but that looks promising. Do you know the price for the full IIDTool - which appears to include the EAS functionality as well as full diagnostics (and if there's any place I could order it)?

I think mine was around $400....

 

Savanna Buzz, thanks for the manual. I think at this point I'll call the self leveling at stop light "normal". I have no suspension errors and I've been airing the suspension up and down for off road use periodically with no trouble at all.
I have an extended warranty on it for another 20K or so anyway so no panic on my end yet. Once that is up a IIDTOOL will certainly have a place in my kit!

 

It is better to call it normal than suggest it only does it when SWMBO or SWMBO's Mom is in the vehicle..... after all, it is a very sensitive weight detection system...

I do wonder what kind of workout the LR3 would have if modded by the wheel hopping crowd...
