mazda 6 dpf

[gnc]

just got an 07 mazda 6. dpf is blocked so im taking it off to try clean it out, any sensible suggestions, was thinking of soaking it in coke for a few days, then a good rinse with water.

1) How do you know the DPF is blocked.
2) And if so, blocked by what.
3) If it's ash, there's probably not a lot you can do about it short of putting a new one on. There are options to ultrasonically clean, but I'm not sure how effective they are on ash.
4) If it's soot, what's the problem - turbo hose split, injectors failed.
5) Has it attempted a regen?
6) Do all the sensors work to allow a regen......

Anyway, loads of questions before you think about cleaning it, and it's not a simple answer.
