NoWelcome.
Best ask in a section where tech peeps hang out, try the discovery section.
We would prefer pics.
As a quickie the rear sensors haven’t by chance gone over limit and reversed themselves, don’t know if it’s possible.

No hight sensors are ok
You have knocked something doing the cables, check height sensor wiring close to the plugs, plus check you have not dislocated the sensor arms or flipped them over, also wires to large plugs just behind nsr air bag on top of chassis.
problem solved . the rear pressure sensor unit .a bent pin in the electric plug.fixedOk go to the disco section and you will be asked to get it on diagnostics which you have cos you have a code, but what reader?
I will lookup that code tomorrow (for 2011 RR) but they usually come close it may help.
But generally forget “U” codes.
