    Possible Solutions

    * Check hoses and/or pipes between components
    * Check / Replace Boost Pressure Control Valve (N249)
    * Check / clean Throttle Valve, do Throttle Body Alignment

    17705 means you have got a pressure drop between the turbo and throttle body ie boost leak, maybe split in boost pipe/ dump valve might be knacker. as for the non genuine maf i dont think it woud be causing this might just be coincidence.
