always bugged me that the front left corner sat lower than the rest so attempted to calibrate the suspension had a fault code for FL signal incorrect and then had a play with the calibrations and couldnt get the fl to adjust up or the front right to go down as the right front corner sat higher than the rest.
so figured must be because of the FL height sensor just renewed that and that code is gone but it still wont calibrate when i adjust the figures i can get the left front to go up but still cant get the right front to come down also when adjusting either front sensor it seems to push the opposite side out.
the rears seem to adjust fine so iam coming to the conclusion that maybe the front right side sensor is faulty?
it does seem to go a bit funny when plugged in every now and again bringing up height incorrect fault?
 
Adjusting any one corner will affect all the other corners to some extent due to weight transfer.
What sort of readings do you get if you use the "get sensor heights" funtion?
You should only adjust in very small steps.
If you use the "go to" function, can you make it go down to motorway and access heights?

You need to be on dead level ground to start with. Changes to one will effect others it's a suck it and see situation. Your conclusion about the F/R maybe correct.
 
its on level ground and the strange bit is, i get moving one side will affect the other but can be upto 1cm, front right seems to do what it wants to and strangely reducing the number seems to make it go up not down.
get sensor heights
there are all within a few mm of calibrated input but its the right front allways seems miles out.
i can set the rears to between 470-475mm at standard height very easily but the fronts allways are left corner lower if i get left front to 470-475 right front will be around 490mm if i try and drop the right front the lowest i can get it to go is 480mm but then the left front will drop to around 460mm if i try and raise the left front and drop the right to bring it back into line it just wont do it there allways seems to be a height difference between the two of a minimum of 1cm.

Definately sounds like the front right sensor, worth pulling off the connector and cleaning it.
 
Have you thought of making yourself some blocks, just for one height, and trying it that way?
 
already tried that! guess better get an order another sensor which is what i was thinking anyway but allways better to bounce ideas off someone else!

Your not sat in the car when you do the changes, then getting out to measure them by any chance are you?
 
I would think the fact it is lopsided,is the reason you do need blocks to lower the suspension onto.At least then you can see what value the height sensors give when they all at the same height.:cool:

fair point but i think the sensor is playing around so have ordered a new one, the problem with making blocks is iam a little one handed at the moment drilled a 10mm hole into the palm of my left hand school boy error! so i can manage a sensor change without to much difficulty but doubt i could make the blocks atm!
 
nope not sat in the car just leaning through the window and inputting changes, wouldnt surprise me if it was the sensor as the left one was really stiff to move compared to the new one prob full of water and crud!
as its a 1998 and they do look rather like originals its not going to do it any harm renewing the right hand side as well at least then i will have a more solid place to start when trying to calibrate

Blocks are not necessary, a stick you can stand on the ground marked with the heights from wheel centre to wheel arch is all that is needed. Not as quite quick as blocks but perfectly adequate:)
