    Default C5 FAP regeneration , "burnt" smell ?

    Can a "burnt" smell originate from a Fap regeneration in a 2008 2.0 Diesel C5, or should I go and look somewhere else for a cause of the smell? Also seems to be more soot at the exhaust pipe end than normal.

    I've been blissfully unaware of when mine does a regeneration (thank goodness). I don't think my FAP has been all that effective since Brisbane Citroen ran some non-total oil in my engine at one of the early oil changes even though it was a low SAPS type. Pipe has been sooty since then and car blows quite a bit of soot especially when the engine is cold.

    Cheers,

    Typical smell when a regeneration is occurring, sometimes there is a more audible noise to the exhaust at the same time. Not noticed with the windows up.

    Thanks guys, up to now and 60000 Ks, the exhaust was virtually still like new.
    The soot and burnt smell, kind of burning rubber smell have appeared for the first time yesterday. There was no particular sound at the time.
