    New Zafira 1.9 CDTi

    Anybody know of problems with the DIESEL PARTICULATE
    FILTER causing problems.
    I bought a Zafira Design 1.9 CDTi 150 bhp approx 5
    months ago and have always had problems with the
    E.M.L coming on and reverting to limp home mode.
    If I turn ignition off and restart it may be ok for 5 minutes
    but then comes on again. Have been into local dealer each
    time and always comes up with code P1901. All they do is
    reset light and clear it out
    Any ideas as this is starting to P**S ME OFF.

    Read the manual.

    Not meaning to sound funny but i see no end of these.
    You can do a regen yourself, and what you need to know is that it puts the eml on when its overful. Doing one regen only empties it so much. So a couple of regen procedures are necessary.

    If you take it back to a dealer tell them to speak to Technical about this as its a known issue and i was told about this at Luton Technical.

    Once the particulate filter is emptied, read the section in the handbook for driving habits, for self gen.
    50 mph for a set time, then the eml will stay off.

    Also the particulate filter status is visible on Tech 2 data display so the tech carrying out the regen should see the level once theyve regen'd it once, so they'll know when its completely empty.

    Hope that clears things up for you, Let me know how you get on.
