Hi just wanted to say thanks for all the info, that hellped sort out the limp mode and warning lights.

two week after collecting the car it went into limp mode, i then cleaned out the egr valve and checked the valve linkage on the manifold but this was fine, car still went onto limp mode after a few miles.

anyway new manifold, actuator and uprated gasket from fiat and she is now running fine.

ps if you ask fiat for the egr gasket, they need to check into the system as the uprated one is under the same part number.
