    Hello, I have a problem with the Mercedes S class W220, namely driving my eska when the engine is warmed up, the EPC ignites and it loses power and the maximum speed is 3 thousand. I connected to a computer and shows the error:
    - 2047-1 Monitoring of rail pressure through a control valve - rail pressure is too low,
    - 2346-2 check EGR (Exhaust Gas Recirculation) system - air mass too high.
    Maybe someone had such a problem, please help because I have no strength. Thanks

    The checked flow is good, the injections are good and I cleaned the EGR

    I did not check the pressure, and this could be the reason ??
