    If its dpf regen related, then longer drive needed or vcds to force regen.

    I could have a look if you can come to me, the drive should be long enough to regen if not ill force one for you

    sounds like limp mode. if you want to pop round now your welcome too, just take it steady.

    all speculation untill you get the vcds scan done.

    Update. Got in car this morning and no warning lights came on. But after 30 mins dpf light came on again so went for a drive to coast and back 86 motorway miles light stayed on until arrived. 86 miles back home with no warning lights. Could it be cured?

    VCDS scan and check soot levels and regen activity to be sure .
