Bumpy road maybe finished off an abs sensor or something along the lines? Is the air suspension still active?

Could honestly be anything then as they are all linked..a plug in should give you a better idea.. I'm chasing similar as yourself but it's brake switch related

My guess is that a sensor has failed, and your best bet would be to get a diagnostic reader to establish which. It is normal to get a groaning sound when the HDC is slowing the vehicle on a slope, but not otherwise. Corroded driveshafts can rub on ABS sensors and damage them, if there is a lot of abrasive material being thrown about that may increase the risk of that happening. Only Range Rovers since 1988
