    Default Help: More engine trouble!

    I have been having poor performance from my Vectra 1.9 CDTi 120 for a couple of weeks.

    I have tried to replace the EGR (have a nice new shiney one sat on my desk next to me here) but two of the hex bolts just won't come off. I think I need to spend some more time in the gym...

    Anyway yesterday the car has started to pop up the Spanner light after around 10mins of motorway driving. My fault code reader says:

    P1901-75 Particulate Filter Pressure Sensor High Differential Pressure.

    What should I be looking at? Where is this sensor?

    Cheers

    Its hasn't regenerated for a while but the car spends most of the time on the motorway. When not on the motorway I don't drive like a grandad

    My fault code reader can check a different things and it says the DPF is 70% saturated so its not that far from needing a regen.

    I might force one using my fault code reader when I get chance.

    Thought i'd better do an update in this.

    I took the car into VX and there were a couple of vacuum hoses split (not sure which ones). They replaced these and cleared the fault codes. It cost £105, a lot less than I though it was gonna cost.

    Now the car has its power back and this fault code has not reappeared.

    Also, its recent trip into the dealer seems to have fixed, touch wood, my cruise control problems???
