G77 Suspension Fault

Anyone any experience of G77 fault code?
Showing a suspension fault message on the dash.

A google search shows this fault code relates to a level control system sensor, rear right, but from what I can see there is only a level sensor on the rear left.

I’ve checked the terminal voltages for the plug on the damper, assuming this controls the adjustment between driving modes, left and right sides are the same - both getting voltage.

Any ideas?
