The Regens drive me nuts. Within the first 5,000 miles, mine was doing regens every 2-300 miles. I was watching the DPF meter--it would creep up to about 1/3 full, and then kick into regen mode which would show on that same DPF meter screen. And each one lasted 40 minutes.
I complained to the dealer and tried to get my mechanic who I have a decent relationship with to tell me how it worked. (worried that if I didn't let it finish, it would just start over.) He said he had no idea what algorithms control the process. He did end up flashing it--telling me the update had something related to the DEF use? But now, the DPF meter is a bit erratic... almost always at zero, and I've only seen one regen in 2,000 miles, which only lasted a few minutes. Makes me think the meter has been "decommissioned," as in, "we don't want you to know how or when this is working anymore because too many people were beotching about it."
Does anyone know how it decides to regen? And can it be interrupted (engine turned off) without it starting completely over? I've been searching the threads to find anything concrete to no avail...
