Hi everyone just joined the forum,I've been watching for a while;very impressive.Anyway I recently bought an EAS activate from RSW and what a great piece of kit it is,it reset the EAS in no time.Unfortunately the fault came back on after a drive up the road.The fault that was logged was 'ARTICULATION VALIDATION' I'm thinking this might point to a tired air compressor as it takes an age to alter height.

I would have thought that 'ARTICULATION VALIDATION' would mean a height sensor is giving an iffy reading, but not enough to be declared faulty by the system. I think the system is being told that there is axle articulation (one wheel higher than the other), when it knows there isn't any, part of the "plausibility scenarios" the EAS ECU goes through. Is the car more wobbly than usual? This could indicate a fault with the cross-link valve which is supposed to increase articulation.

There doesn't seem to be anything untoward with the ride quality that I've noticed and all corners seem to be level.Once I've reset it I can raise and lower the car ok and the fault doesn't seem to come on again unless I drive about half a mile then on it comes.
