L322 2006 3.0TD6 Suspension issue

Have you checked all the fuses? In glovebox and behind the rear o/s panel in the boot theres a maxi fuse and the relay there.

Thanks for your reply, yes checked, all ok, that was the first job I did.

Hi again gents, just received s/h AS module, plugged it in and the off road light is lit. Start the engine and operate the control to raise. The light to the left of the motorway blinks for a few seconds then both go off until I restart the engine.
Then the off-road light illuminated again However on the RR screen where it shows the four wheels and the steering angle, the nearside front wheel is shown as way lower than the other three. In reality all four wheels are level on the bump stops.
The compressor did not activate.
Does that mean I should replace the level sensor?

I do not know if it's necessary, but have you done the steering lock to lock reset?
The only way to be sure about the sensor is diagnostics, however have you checked that the sensor linkage is correctly in place ?

Thanks for your reply. Yes, did the steering lock to lock, but not checked the sensor linkage yet. Will collect a jack in the morning and take a look and get back to you. Cannot get to see at the moment as its literally only about 7 inches off the tarmac.

Hi again gents, update, got the jack but Rangy is to low and ramps are to steep without trashing plastic strips at the front, anyway a couple of blocks of wood will get round that, however discovered that the battery is dead so now on charge. Hopefully will be fully charged by the morning.
Cheers Diverivor
