There were many posts on this a few years back. Some referred to a MB document that mentioned 125,000 miles.

It depends!
I have a van with 300,000 on it and it's still good!
On the other had I have just installed a reconditioned MB engine on another with 310,000 on it and it (DPF) was plugged with 55 grams of soot & ash!
.
The difference is what is happening upstream with the engine!

Dumping, pumping , burning oil, bad maintenance, driving /operating habits --Well you know its all been discussed here on these forums over the years.
The best way is to conduct a health check I suppose and see if the system is doing what it should and how much ash has been deposited and recorded in the the DPF!
