    Hi,

    From your scan, I would say the EGR valve is still present and faulty. It may be that the car has been flashed to not use the EGR value but it is still physically fitted to the car and looks to have developed a short circuit.
    Unless it has been removed and the wiring hacked-up as there seem to be a number of electrical wiring issues here.

    Limp mode likely caused by MAF and boost controller errors.
    Check the wiring at the boost controller. The wires like to break under the boot at the connector.
