DPF regeneration - mileage interval?
I realize that DPF regeneration cycles are initiated by reading from the differential pressure sensor which measures DPF blockage. But does anyone know from experience if the cycles can also be initiated from accumulating mileage? Example: if no regeneration cycle has been intiated within the last 750 miles, one will be started. I am asking primarily due to my interest in the ml320 cdi, however i imagine it might be common accross all merceds vehicles which share the OM642 engine. M series, E series, and maybe more.

My 2008 Jeep Grand Cherokee with the 3.0L MB diesel regens every 750 miles like clockwork...the regen will take place for about 15-20 minutes with temps getting to about 1300 degrees.
I have a Dashawk that I can watch the temp increase and the time. I know exactly when I will regen based on the 750 miles.
I have 64,000 miles on my Jeep. The Dashawk will provide me the means to monitor the regen...any deviations from the 750 miles will raise red flags for me that maybe the DPF is getting full.
Hopefully that is a long way off.

E320 Bluetec DPF Regeneration
In four years this happened to me just once when Regeneration occurred while I was reversing my vehicle into a parking space at the bank not having driven the vehicle on the road for quite some time; all other times I've noticed only while driving at speed. It was quite strange; there was lots of smoke for a period of 5-10 seconds and I mean a lot. The days prior to this occurrence and during extremely low level of driving activity (only in and out of the garage) I noticed an increase in diesel stink which eliminated or rather reduced to a normal level post this occurrence.
