Going back 10+ years, I read articles saying that deposits baked on to the DPF weren't all the same. It was said that engine oils heavy on magnesium created deposits much more tenacious than oils that were primarily calcium based (speaking of detergents).
State of DPF depends on oils used. I know some people who meticulously maintained their M57 in BMW and did cleaning. I know also some who used all kind of oils, bcs everything is same and it is just big conspiracy, and cleaning did not work.
