Does the TUD Engine/Bosch Pump have an "inertial fuel cutoff switch"?

  1. #1
    I had a deer jump in front of my 106 and it did a fairly hefty bit of damage to the front of it:



    It does still run, just. It splutters a lot, it gets a lot of smoke out of the back. It's as if the timing is off.

    I also have a Citroen Synergie with an XUD engine and just noticed under the bonnet a sticker saying



    This vehicle is equipped with an inertial fuel cutoff switch which interrupts fuel supply in the event of a collision. Refer to owner handbook

    Are 106s also fitted with these? Could this be the problem with my 106?

    Yes quite a few will have an inertia switch, look on the engine bay near yhe servo -fusebox area.


    However if it actually runs this will not be the problem.

    I assume then it's not possible it's only partially disengaged?

    No. It's a switch - either on or off

    whats the state of the front end currently?

    I would be checking the fuel lines, filter etc, anything that may have been damaged, it could be an air leak.

    Intertia iirc is right next to servo. Big red switch.

    As for the spluttering, could be anything! Check for loose connections, any MILs thrown? Get an ODB hooked up if available and see if any of the stats are off.

    Possibly intake, make sure no splits / rips / cracks.

    Also, does it do this Idle, all the time? At a certain speed?

    lol

    its a phase1 diesel, no obd, no mil, no ecu!

    Yup on the lack of ODB, it's proudly ECU-less

    As for the state of the frontend, the radiator has leaked but it was all on the left side of the car, so it narrowly missed the pump itself. We did keep an eye on the fuel lines and it seemed clear - no bubbles or anything.

    I described it to a diesel specialist and he reckons there's a good chance the belt has jumped a tooth and knocked the pump timing off, making it relatively cheap to fix. it's possible the pump/engine was pushing against the momentum of the car and caused this I guess
