L322 Range Rover suspension

Just serviced the air suspension valve blocks, one in each offside wheel arches.

Put all back together and the offside will sit on low height while the nearside is on normal so she lists from side to side.

Engage high level and all pumps up high and level. But when I switch back to normal, near side goes to normal but the offside goes to low.

Tried disconnecting the battery and touching the + & - together but no joy.

Any ideas?

Level sensor been disturbed?

No. not that I noticed,
But both front and back offside lower to the low ride height so I do not think I would of knocked both of them.
.

Allcomms will recalibrate it and check for faults I honk it's the best value diagnostic kit you can buy if you have an 02-05
