So just over a year into my ownership the car has decided to have its first hissy fit.

The Yellow Triangle followed by Red triangle appeared saying suspension issue. I plugged in my GAP IID and got the following errors:

The low voltage of the RF sensor is not necessarily incorrect. The LF is higher than the LR by more than the RF is lower than the RR, noting that the right sensor voltages increase and decrease in the opposite direction to the left sensors as height changes. Compare the voltages at access and off-road heights to see how they change.

So just to update, I changed the relay put a new silencer on and re calibrated the suspension and fingers crossed this at present has seemed to fix the issue. Fingers crossed it remains this way.

Thanks GraemeS for your advice. Current

So, that didn't fix the issue and I have now got to the bottom of the issue. The fix that was needed was to put new Exhaust Valve seal repair kit from 4x4 Air Seals which has now fixed the issue. Current
