What is called a Catalytic Converter on our HDJ100s, is actually a particulate filter (DPF). It reduces the size of the soot particles in the exhaust fumes, and it does get clogged up over time. There are no sensors, or anything similar, relating to the functioning of the filter. Often you can get a turbo pressure fault code when the pressure required to overcome a blocked DPF is too high.

Huh, uHu, where do you get that from? Not that I doubt it and it makes some sense, just wondering.
When blocked it kills the turbo as well. Don't ask me how do i know...

What exactly?
I experienced that when I floored it, I got a wheezing sound under the floor, then lost power and the CEL came on. Stopping and restarting made it OK until the next time. Checking TechStream revealed a turbo pressure code. I changed the DPF, and 100 k km later it's still OK. No turbo fail, and no more codes.

PS: I'm now well past 300 k km and expecting the turbo to fail within 50 k.
