Hi need some help

Sorry does that just clear the faults or does it actually recalibrate the system as another member asked if I had had tyres changed which I had and it could have been the tilt sensor from being jacked up incorrectly ?
 
It needs to be jacked up in the correct procedure, if you don’t it will cause mayhem with the suspension system. Whoever jacked it up wrong may be responsible for correcting it for you?

How to recalibrate the system after can probably be found in search bar, if you are lucky @Saint.V8 will give his Penneth worth
 
The L322 calibration using the All Comms process is mostly automated....

When the system is placed into calibration mode using diagnostics, you tell it the rim size fitted (lets say 19") and the vehicle will automatically raise to a datum height. This is a certain height reading as provided by the height sensors....Lets call this figure 'X'

You then grab your favourite tap measure and measure from the bottom of the wheel rim to the lower edge at the centre of the wheel arch and put this figure into the Calibration Screen, lets say you measure 767mm....

The EAS ECU then does some funky maths and knows that when at reading 'X' the vehicle is at 767mm.....it knows that when sitting on 19" rims at standard ride height it should be 753mm, so in order to be at standard ride height it needs to move until the height sensors are reading 'Y'....and so it settles down to standard height....and using the power of extrapolation it automatically works out what the height readings should be for Access, Motorway and Extended.....job done.

You would think that with all the kit on these cars, a proximity sensor on each corner to measure distance to ground and self-calibrate on startup would be a piece of cake.

Bump stops and full extension and you have the 2 maximum values. Job done.

Hi thanks V much for that info much appreciated
 
How is it legal, ie how do you pass an MOT if you swap from self levelling air bags to springs? As soon as you put some weight in, the non adjustable headlights point up to the sky and dazzle other drivers
 
i seam to remember some one on here posted they had changed there l322 to springs as they were out in the sticks an parts weren't available .

They don't check for self levelling of the headlights on the MOT, only that the headlights are correctly aligned in the condition the car is presented in.
