L322 suspension fault

Hi - has anybody any suggestions please. I recently posted a fault that I had with my 2010 L322 Range Rover. The rear suspension was dropping intermittently when left parked. I put a diagnostic tool on it and it showed a fault code of CA106 Rear height sensor. I have just changed the height sensor with a genuine part and the code cleared. Now when I drive the vehicle of 30mph the suspension drops to fully lowered position and a red suspension warning comes up on the dash. On plugging in the diagnostic tool it now shows two faults Rear height sensor and a CA107 cross articulation. Does any one have any suggestions

Want diagnostics do you have?
Did you calibrate the new sensor?

I have not been down this road yet so just asking.
