DPF Issues... (Update page 4, March)

[Toms306]

Don't know much about these DPFs but could you not do something like running the engine hot like redlining it to blow the ash through or whatever? Italian tune up?

Redline a diesel!?

Still not hot enough really, forced static regen gets DPF temps up to about 550c! It looks just like 4k for 5 minutes but there are other methods it uses to heat up the exhaust at the same time.

Don't confuse soot and ash though. During the regen soot gets burnt, but as with burning anything, it leaves like 1% as ash...this ash is still too big to fit through the DPF so will be held there indefinitely... Until it completely blocks and you end up in limp mode (no DPF light like there is on VAGs, well done Ford!) or 75k miles where Ford say you have to have a new DPF fitted anyway lol.

Steam cleaning works but the opposite way to exhaust flow. So pull dpf off and go nuts

I've seen jetwashing them on youtube, is there enough force in a steam cleaner to do it? Not that I have a steam cleaner anyway lol.
