    Hello.

    Colleagues, I have a problem with this car. It wont start.
    The errors he has are:

    P1541 - Fuel pump relay - Break
    P1018 - intake manifold flap 2 - lower end position not reached
    P3348-005 control of turbocharger control unit - electrical fault

    Permission to start is.

    All joints under the left cover in the shaft were tarnished. badly fitted lid and gasket rolled up.

    Maybe someone can figure out the wiring diagram for this engine.
    Any hints.

    best regards

    The fuel pump turns on?
    the other two errors will not affect the ignition of the car.

    Of course, the pump does not start.
    I tried vcds em through test el. exec but it doesn't work like that either.

    Relay and fuses checked?

    Of course checked. Wszystkiue.

    On the shaft on the left is replaced because it is j17 from the fuel pump.

    Now there is an error P1633- accelerator position sensor 2 / signal too low

    I didn't touch the accelerator today.

    If someone could tell what the relay 395 is next to 614 on the shaft on the left.
    This 614 is like J17 from the fuel pump but if I give the weight to one of the 395 relay legs on which after turning the key is 12V, it turns on the pump.

    I have an overview diagram from the SSP and there is no relationship between the errors at the beginning and the accelerator pedal.
    Unless something is with the engine control unit.

    the 395 is just a pump. the latter is responsible for energy management - this is the scheme

    My mistake, I spun myself.
    395 as a colleague wrote it is J17 from the pump.

    Then it fires up?

    I will only add that with such mass administration in different places from yes, sometimes it has negative effects.

    Yes it fires up

    Dude, I know that.
    I cut the cable before proceeding to feeding the mass

    Connect the bulb to the cut one and see if the controller controls the relay.
    Ideally, the driver will know if the driver is damaged or the harness.

    At the helm, it comes out after turning the 2.57V key and after reversing it lasts about 30 seconds.

    There is no tension on this cut off.

    There will be mass there. At the controller, connect a 5W light bulb. One cable for the controller, the other for the plus.

    That's how I hooked up. It did not shine.
    Later I checked with a meter.
    Free rudder?

    Connecting the cable back at the controller and at the relay as a factory punishment when turned to ignition is + 12V

    You have voltage from the relay coil, that's how it should be :)

    I haven't touched the gas pedal at all today.

    Hello .
    Sorry for reheating the old chop but I have a similar problem - see error on the acceleration potentiometer in similar natural circumstances.
    Has the problem been resolved ???
