Hi all. I recently purchase a 2010 Range Rover HSE. it has bad Height sensors on the front. Is there a technical difference between height sensors for the variable dampening suspension and the non-variable dampening suspension? Cheers

How do you know the height sensors are bad? Has it been on diagnostics? The height sensors are pretty reliable.
 
First, it had a popped front air bag and would fault out and drop to the bump stops. I replaced both front struts. On the 4x4 display it would show the front right side down when it actually was up and kept the compressor running until it would fault again. I tried to calibrate it with RSW solutions software tool and it wouldn't work.

So either the sensors have been over run causing damage or the actuator arms are displaced.
 
I believe it happened when I changed the front struts. I bumped the stand and the right side fell and may have over extended and caused the sensor to become damaged. It reads at 79 even though the strut so full and over extended the bag gets misshapen. The system is constantly trying to fill it to the correct height it gets hot and shuts down. After repeated attempts it faults out and down she goes.

It also read one fault: "Cross articulation-signal compare failure"

If you believe there to be a problem with the sensors, especially as you seem to 'know' you damaged them. Why not change them? As for is there a difference, when you put your registration in, or tell the seller your year and model , they should supply the correct part.
 
One last ditch attempt.
Can you remove the sensor from the arm and move it yourself to see if the reading changes?
If it doesn't then it's buggered...
What does your gut instinct tell you?o_O;)
 
I bought both from the local Land Rover dealer and replaced them. The right side sensor was cracked. Problem fixed. Didn't even have to calibrate them. Checked the calibration anyway. Checked the live data and raised the suspension for S&G. Everything went well "knock on wood".

My reason for the initial post was because when I received my new sensors they were for the "Variable Dampening" suspension. Mine has the "Non- Variable Dampening" suspension. There is a difference in the wiring. Non has three, variable has 5. I ended up swapping them out at the dealer. There was only a $5.00USD difference in price so no big deal. Parts guy said they probably would have worked since the main three wire locations, (pins 1,4,5), are the same but I wanted to be sure. The VIN doesn't clarify, it can be either.Thanks for the comments and help.
 
The Variable Dampening struts are twice and then some more than the non*. Plus the sensors and what-not that goes along with it. Just one more system to go wrong eh?
I'm getting to know this Rover. so far I've replaced both front struts, both rear bags, air line at the front right side, both front height sensors. Of course I didn't really have to do everything in pairs but figured that's the best to keep it all even. left front strut and left rear bag are still good albeit old and dried out. the left front sensor is good so I guess I have some spare stuff if I'm in a pinch....lol! funny how every thing bad was on the right side.??? Now I have a transmission leak and fluid/filter change to sort out. I might let the dealer do that depending on how many arms and legs they require. Oh!.....and change the engine oil/filter. I figured I'd have to spend some cash and time on it but my wife loves it so it's all good....she's worth it.

Collecting "come in handy" spares,welcome to the club.you'll end up with a shed like @Grrrrrr 's he's got enough to build another car.:D Well done for sorting your problem and its always best to replace both, if one goes the other won't be far behind.;)

Your missus or the car??:p;)
As a rule done in pairs to maintain an equilibrium.
The fact that the shock assembly pricey makes it a financially tough decision.
Now get out and enjoy it:cool:

I am waiting until they're worth something. Most of them are waiting to be fixed / repaired. I seem to spend my life repairing stuff for the missus and kid. Cannot keep up with demand. :/
