Has anyone come accross a fault in the air suspension "Ride height Mode - Invalid" Everything appears to be working Ok the rear suspension sets to right height but the front goes to maximum height and the control switch on the dash wont do anything it just flashes at the level you try to set but doesn't actually do anything. If you drive for a distance like this you get a message "Offroad Mode 30 mph" and a short while later the suspension is inactive. I have tried re-callibrating the suspension but it makes no difference.

Any faults recorded?

The only one that comes up is "too much energy for regulation needed: front axle". The main problem is "Ride height mode: invalid"

I do not know, but that could suggest a leaking front airspring.

I would read the live data for the front height sensors on diagnostics and see what height the sensors are telling the BCU and go from there.

You said you tried to re-calib the suspension, what diagnostics you using?
