    Electrical problem 2.0TD (P1650)

    Hello

    i have some trouble with the electrical system.

    Lamp for electrical error in dash panel turns on if i give to much gas, or have to much rpm, like over 3500. Then it feels like the turbo is gone (engine pull is poor, until reset again). Have to stop and turn ignition off and on again to reset lamp, and everything is then ok until next time i run over 3000rpm..

    I think there can be some air / vacuum problem

    Codes are:
    P1650 can disable
    P1651 can wrong
    p1125 system error
    p0400 system error 2

    Please help
    Thank s

    Sounds like it could be a vacuum problem. I only know the P0400 code but Google found the rest.

    P0400 Exhaust Gas Recirculation
    P1125 Boost Pressure Solenoid Valve
    P1650 CAN: Device Offline C-14
    P1650 CAN: Device Hangup C-14
    P1651 CAN Receives Error C-14
    P1651 CAN Transmits Error C-14

    Could be a solenoid valve, or just a vacuum leak.

    Do a search in this forum for vacuum, and leaks or problems if you like. There are loads of threads about them saying about how to check and where the pipes go.

    That particular solenoid valve is at the back of the engine near the turbo but I'd check for vacuum leaks first.
