EAS fault ??

hello all ive been up to the top of scotland and back again with not much trouble with my P38 the only problem ive got is every so often it clicks off and says eas fault so i check it out and it says vehicle has moved and something like vehicle pressure high or something like that, sorry it's a bit vague, any ideas would be appreciated i'm thinking my pump is getting tired or something like that ??
regards Paul

If fault is "pressure signal constantly high" it is an symptom of a failing valve block driver module.

Could also be connection problems or even a height sensor.
