L322 High air suspension on

2003 3rd 6 had it 5 weeks
Hi all my high led is on all the time. Just changed the gearbox oil and had this happen. If I use the manual lift lower,access rotary it appears to lift to standard and high but the high light remains out when it tries to reach standard and the standard light keeps flashing when it makes access . When I try access it tries to drop but doesn't sit on its bump stops at the rear but does at the front and again the high light is on and the access remains flashing. When I try high it makes high and the high light remains on as it should.
I've tried the rsw software and it reports no faults ,I'm totally lost.
I drove it up on 4 axle ramps so no jacking involved.
Any help appreciated
Thanks

does it sit level at standard height? just thinking if the front is low it hit's the bump stops so the ecu thinks it's stuck

Oh yes sits fine and I can use the rsw to adjust all four corners if necessary

is it sitting at the correct height

I wish it was ,I just started her after 24 hours and .....the right side has gone to standard but both the left hand front and rear have gone to high. The standard height light is flashing but the high led remains steady on . I used the rsw solution and it records no faults !
I used the rsw to depressurise the system but it took ages ,over 10 minutes to settle on her stops .
I also checked the live data on the rsw and the front left
Records minus 7546
Front right says 0
Back left records 5
Back right is positive 8654.

On the get data on it the current heights are identical to those stored in the ecu ?

Im really confused by it all
