Suddenly picked up a really weird error with the EAS. the only thing I can link it to is doing over a bit of ground which put the RR to its full articulation.

Since then, I've got an articulation plausibility error which wont go away.

Reading the fault mate readings, I'm suddenly seeing negative values for a couple of the sensors:

I'll answer the first part of the question .... the wee arms are the correct way round on all 4 corners.

I find it wierd that that its the front left and rear right that have suddenly got the issue ... the only thing that links them I can see is that the supply voltage to the sensors is shared ... but according to the diagnostics, its a rock steady 5.05V

Hmmm, its wierd. V8 or else ...

this is funny as i was taking to a retired LR technician and he told me that they had many cars in with similar faults to yours and it was caused by jacking the car up, he said that you should always have the suspension in the normal mode,ie middle setting.did you say you have been putting it through its paces V8 facelift Range Rover Autobiography 22" wheels.

There isn't enough movement in the suspension for the sensor arm to flip over

I notice on the Blackbox support forum that the Light Check Module (SM058) may also store the error and so may need clearing too?

Agreed - its definitely not flipped over arms.

Phil, that is an issue that affects my RR, and I reset both the EAS and LCM when I reset the EAS. I've done that a few times tonight and its not cleared the error.

Daveo ... not as such, and not what I would consider worse than anything you see on a land rover experience picture where the car is at full articulation, wheels in the air type thing. I drove from one angled piece of tarmac maybe 25deg angle down to the right up a short steep slope to a level piece of tarmac.

Not sure if it helps, but here is a chart of the values from a run down the road.

It shows sensor volt reading value and their what the ECU outputs as what it describes as height in mm.

Well I agree with daveo.
I've managed to flip over a sensor on a 2002 (NS front as it happens) ..... the small link rod bows a bit.

Cause - jacking it up too far.

I've read of a flipped sensor on a P38 - but not on an L322 (IIRC. I suffer from CRS )

Have you simply looked to see if they are the same way left to right of the vehicle? If the issue is with one side front and one side rear, check the height sensors arms look the same way round on both sides?Surely if they had flipped over they would be facing the opposite way now...

I've looked, all arms are facing the correct way.

I messed around last night with it and got a little success, but it's not quite there yet.

Will try at the weekend some more ( essentially a full calibration of heights ) and I think that should sort it. V8 or else ...

OK - a quick update ... i with the engine running and the Faultmate showing the sensor readings live, I unplugged the front left sensor and its value went down to 0.01 and the rear right seemed to jump back to match the value of the rear left.

I'll need to double check it , but it does look more like the front left sensor is a more likely source if my issue.


however .....

On telling the RR to raise to access height, it jumped up at the front and suddenly HIISSSSSSSSSSSSSS.....

Suffice to say, it would appear my front left airbag has split on the inner side. ....

2 front struts now ordered .... ahhhh!

anyone know the front left sensor part number ? ( 2002 4.4 V8 HSE ) V8 or else ...

I got in the car today and with a loud bang the front left spring let go. I rigged up the IID Tool and got strange readings on the callibration with the left front showing callibration of +400 or so where all the others were around 150-180. Any idea why this would be?
I obviously want to get back to something like factory settings after I change the spring and dont want to immediately pop it again. I take it about 150 or so is a reasonable start?

I checked each corner in turn with the check valve function and LF wouldnt budge but RF was pretty slow so will do both. Are the fronts more likely to go than the backs? I have never had to do rear ones yet but this will be the 3rd set of fronts though at least they are a lot cheaper these days!

Since it's popped back up ...

The error to this was fixed by replacing the sensor with a new one which had a slightly different design. Error immediately went away. V8 or else ...
