Thanks for the offers/information guys, the more I read on here the more I might give it a go myself. Took my RR out at the weekend and covered over 80miles with no eas fault, suspension worked as it should. Think I will look at the connectors in the passengers footwell for the EAS to see if it's just a bad connection.
Andy, if you want an extra pair of hands sorting yours just shout, perhaps between the pair of us we could get yours sorted!
