So i played with the button that raises suspension while sitting in the car while the wife went to get my beer from the off licence and it was like i was on a ride at a theme park

front nearside lifted then rear offside then all four corners joined in for a moment and then jiggered around before stopping, felt dizzy.

Wife arrived and said the left side of the car is drooping, checked my beer she had been sent in for and all was accounted for so i checked the droop myself and the left of the car is lower than the right in access mode.

Suspect the car should not be tilted to one side when in access mode but is the jerky suspension lift common?

P.S i did not at anytime introduce my alcoholic beverage to any part of the cars fluid systems.

Sounds like it could be a ride height sensor, there was a TSB issued for this fault.

Thanks Jim

Its due to be booked in to be looked at, but is the raising from access to standard height suppose to be so jerky? or should i be mentioning to my dealer while looking at the ride height sensor, to check compressor to?

Cheers.

Mine is smooth but does rear first then front.

No messages / issues but it seems that how it raises on mine.

Thanks Guys

Obviously mine needs checking then, hoping they can fix the jerkyness at same time of the lean while in access mode, may be related.

Your suspension works as it should be: first rear then front. Also, keep in mind that you have two separate devices for rear and front suspension. The front has its own reservoir, not sure what the rear has, but its different. Sometimes, front reservoir needs to "re-charge" and therefore it may lift the front at a much slower rate than the rear side. That should not be of any concern as it is also, you guessed it, normal. This usually when you leave the car parked for some time. So do not worry, your suspension is fine.  Vadim A.

The dynamic suspension system is a four corner air suspension system which is fitted as standard to all models. The dynamic suspension system is electronically controlled by an air suspension control module which controls the air supply unit, reacts to inputs from four height sensors and distributes air around the system via valve blocks.

The main air suspension system components are:

** Air suspension control module
** Air supply unit
** Four height sensors
** Three valve block assemblies
** Reservoir
** Air harness
** Four suspension air spring damper modules.

The four corner air suspension system maintains the vehicle height under all operating conditions by controlling
the mass of air in the air springs. The air suspension control module uses signals from the four height sensors to maintain the correct suspension height. This is achieved by operating pneumatic control valves to increase or
decrease the mass of air in the air spring damper modules.

Thanks Guys

Very informative...i love this site.

Not sure of the MY2010 system but ...

Its all one device.

Hi Vadim,
This is most interesting.
I am aware that that on the MY2010 models there is an addition (improvement?) to the suspension system - continuously variable damping, known as Adaptive Dynamics which is standard on 5.0 S/C variants and is an optional on 5.0 N/A and TDV8 variants.

The basics (design) I thought were still the same, as I mentioned above.
So there are two reservoirs now - one for the front and one for the back? Completely two devices?

Could you find out more?

Thanks. Malaysia Boleh!

Hi Bobby,
I will try to find out more, no problemo!  Vadim A.

Here it is Bobby,

Copy and paste from LR factory report:

THE FRONT AIR SPRING PRESSURES ARE HIGHER THAN THE REARS (10 TO 12 BAR VERSUS 5 T 8 BAR) SO WHEN THE RESERVOIR STARTS TO BECOME DEPLETED, THE REARS WILL GO UP QUICKLY (USING THE RESERVOIR) AND THE FRONTS WILL RAISE UP SLOWLY USING THE COMPRESSOR. IF THE SUSPENSION SYSTEM HAS HAD SUFFICIENT TIME TO RECHARGE THE RESERVOIR (TYPICALLY 5 MINUTES OF ENGINE RUNNING FROM A COMPRESSOR COLD START) THEN THE SUSPENSION FRONT AND REAR WILL RAISE QUICKLY. THE INSTRUMENT PACK MESSAGE HAS CHANGED AT 10 MODEL YEAR FROM “SUSPENSION LIFTING SLOWLY”, TO “VEHICLE RAISING IN PROGRESS”.

Seems I got it a bit wrong... there is only one reservoir, however it certain circumstances the front side will be raised using compressor. Vadim A.

No worries, understood!  Malaysia Boleh!
