    Is there a guide on how to clean the MAF sensor somewhere ? I've had a look but can't see anything, I've got some electrical contact cleaner today, do I need to remove the whole thing or just take the sensor out if the plastic tubing & clean that on its own?

    Any help much appreciated..

    Pull off air duct that channels air to filter housing.
    Unplug MAF sensor using small flathead screwdriver.
    Using a torx bit with indent (hollow end) undo 2 screws holding MAF in place.
    Remove MAF and give it a good spraying with the contact cleaner until clean.
    replace, refit screws, plug, duct.

    Cheers for that, I took the whole maf housing off and sprayed thoroughly inside , hopefully that'll have cleaned it ok, I think I've found the problem now anyway, boost pipe not connected properly.
