    It will need an EGR valve. The diaphragm in the actuator part splits so the EGR can't open, hence the fault code. They are around €110 ex VAT from VW.

    Is best to put in a genuine Vw egr when replacing ?

    That's what we use in them anyway, I'm not even sure if they are available elsewhere tbh.
