Does anyone know if this is an easy replaceable job, Im getting error codes relating to the Valve and High rail pressure, obviously the pressure is high so im assuming the pumps are making good pressure and the rail pressure seems high so I can only think its the control valve that isnt managing the pressure and that's what needs to be replaced. I can see it on realoem (see below) but have no idea where this is on the engine....can any one help before I get my hands dirty?
