I didnt clean my manifold. ideally you'd want some thin pipe cleaners and some sort of solvent that was going to dissolve the gunk but not harm the plastic manifold. I didnt have either, and it was such a thin layer on the sides that it wasnt worth messing with.
abeardo: if the DPF isnt regenerating automatically you need to make sure the engines warming up properly (thermostats) and make sure it gets a decent run every couple hundred miles.

I think it was just at the point where the DPF was nearly full with the sooty remains from the regens tbh. The garage did a forced regen and a Terraclean and *touch wood*, it seems to have sorted it.
That Terraclean is good stuff, it seems. Car really pulls again now. Am thinking of giving it a go on my 335i at some point.
