I have a 06 rrs its had a brand new pump and software update for the suspension by the previous owner at the dealers and its been working fine without any issues all level and holding whilst parked.,

that is until recently when the car went into a local garage to have a new n/s bottom arm fitting .

the cars come out of he garage but ive noticed it sagging on osr and its about 30mm lower than the rest. Ive tried putting it up and down taking it for a run but it wont improve.

Is it something that could have knocked the calibration our perhaps of they've had it up on the ramps?

its now lowering itself right down to the access position after just 24 hrs.

Is there some laptop software i can get cheap enough to read the codes and calibrate it/>

Have seen it said that jacking up can sometimes upset a height sensor. They are quite crude sliding potentiometer design and suffer from dirt/corrosion that can be disturbed by jacking up. Luckily they are not expensive and easy to fit. Your 4x4 screen should show a height sensor fault.

Unfortunately there is no laptop solution to the fault code reading problem (at least not for LR specific codes); need to buy a IID tool or have them read by an indie with the right kit. 2008 MY Java Black TDV8 HSE

Hi how do i check to see if theres a fault on the 4x4 screen

thanks

Get the 4x4 info screen up and select chassis view ; the one that shows the four wheels. If there is height sensor fault the bar over the offending corner is in red instead of white I think (never seen it on mine so not 100!).  2008 MY Java Black TDV8 HSE

i actually took it into have 4 wheel and they said they couldnt do it properly because it was sagging on that corner obviously it effects the camber and everything .

at the minute the alignment is way out
