    As above, it's because of the Diesel Particle Filter. They are a right royal pain in the rear when do a regenerate.

    Put a coat of sealant or wax on the tailpipes when you've cleaned them to make the job easier next time. :)

    If you are getting soot deposits, you probably don't have a DPF.

    My friend has an almost new c class blue efficiency in white and the rear of the car is always covered in black dust.
    Does this have a dpf?

    Far better to have sooty tailpipes than having to deal with a DPF!

    I would rather try to get rid of this soot !! as most modern diesels in car and machinery have no soot deposits I think it maybe the short journys I do and it realy needs some long one to blast it out :>)

    Might be worth spraying a bit of WD40 just above the tailpipes so the soot can't attach itself.

    And give it a good blast out once a week.
