Diesel Particulate filters will accumulate ash, and if sensors fail and are not repaired, soot, can build up to the point where on-vehicle regeneration is not allowed by the ECU, due to danger of damage from excess heat.
(soot is normally captured in the DPF, and converted during passive and active regeneration almost totally to gasses that exit the tailpipe. ash is the small amount of material in that soot that cannot be converted.)
Want to start a discussion on options for cleaning DPFs, off car or on car.
Google reveals plenty of options for DPF cleaning services and products,
there are some products that move carbon around or claim to improve regeneration.
cleaning services use a combination of baking and air flow (in the reverse direction of exhaust flow), and in some cases ultrasonic bath (like my wife uses for her engagement ring, only bigger) to coax the ash and soot from the surface.
http://www.fsxinc.com/ sells cleaning equipment and will clean TDI DPFs.
http://www.dpfregeneration.com/ is another service, they charge $400 (as of May 2015) to clean a TDI DPF, with whatever is attached. (2009 design includes DOC and SCR cats, 2010 and later have the SCR cat in a separate part) shipping and removal and re-installation not included.

includes description of using oven cleaner and water to clean the dpf of on over-soot-level DPF, followed by VCDS reset, as an option to replacement or send-away cleaning.
Comments/discussion? Please share opinions, and especially if you have had your DPF cleaned and back in service.
