    Default CDTI 150 Flat Spot is back!! Where is the Fuel Filter?

    The flat spot between 1k and 1.8k rpm is back on dad's CDTI 150.

    I read a thread last night, cant remember now, but someone mentioned something about changing the fuel filter.

    So my questions are:
    - where is the Fuel Filter located;
    - how easy is it to get to and replace;
    - how much am I looking at for the part;
    - is this likely to help with the problem as it also still has the slight tremble on idle!

    Oh and another thing, CDTI 150's!

    there is a little clip on it to stop it from moving toward the front of the car just move that and give it a bit of a twist and a pull and a kick and a punch and it should loosen up, releasing the pipes is prob the hardest part m8.

    Is this a Service item? Also, could this contribute to the issue I am having?

    No, the fuel filter is under the bonnet towards the back, almost in the middle - its the large round black thing with pipes going in and out of it. You remove the pipes going in and out and it lifts up out of the bracket (although it could need a fair shove to get out) then once out the top is removed (there is diesel inside BTW) and the filter comes out, new sealing ring and new filter put back in place.

    The filter is about £22 from VX, and by all accounts its best to get a VX one.

    I think the thread you mean is the one regarding fuel/injector treatments - they can clog the filter and cause some hesitancy and misfire symptoms - does your dads still run smooth, but just sluggish, still leaning towards EGR issues..?

    Hope this helps.

    i like to treat as a service item m8 when i do my annual service but didn't bother last year. i think it is recomended to do it every 2 years or something similar. as regard the issues ur dad is having m8 i haven't a clue if i'm honest, but changeing it can only do good m8.

    Yes, its under the bonnet (under the 't' of the word Boost - with the blue clips).
