If you do interrupt it, the cooling fan will run on high a bit after shutdown.
Since we now have (in the USA) a 11 year 162,000 mile warranty in most cases, I would worry even less about the DPF cracking due to the thermal stress of an interrupt regen.

Well, glad to see I'm not alone on this one. I think the TDI crowd are, in general, more "in tune" with their vehicles. I know they are supposed to work around the mid regen shut down but I really dislike stepping out of the car, fans running like it's an airplane about to take off and car smelling like a bonfire.
