Front left 460mm, front right 470mm, rear left 465mm, rear right 470mm,,,, we cleared all the codes but I’ve not had them cleared since I changed the centre valve block we did try to calibrate it but it kept saying couldn’t do it because couldn’t contact the left front sensor,,, but since the centre valve block change it’s running as it should fault light decides to come on when it feels like it and when it does it no longer drops to the bump stops but if I flick the switch to change ride height to off road or access it moves about an inch and says normal height only,,, hope this info helps as I’m new to all this cheers for you input so far much appreciated
