    Anything I get my hands on.
    Give the EGR valve a good clean first to see if it clears the fault.

    If this is on the E300, EGR don't generally give trouble, so look for a vacuum leak or ruptured actuator diaphragm.

    As E270 owner says, try cleaning the valve, if that doesn't fix it it's either new valve or EGR Shunt time.
