    Red engine light flashing derated the engine so I took it to the dealer they cleaned the dpf filter and ran a regen then 20 minutes after I drive out of the dealer the regen light with the yellow check engine light turns on again.

    Why would it ask for a regen so soon what could be wrong with it.
