I am most interested in this solution. Can you give the mix of water and caustic drain cleaner? Also what brand drain cleaner - just out of interest? I have a few other questions but they're probably better for a pm. Can't do that yet!
Cheers,
Mark

Both have some type of sensor at the engine end. The second has what looks like 2 vacuum lines one front one rear.
I removed the later chamber and cleaned it. Firstly I stood it on its end and filled it with water and caustic drain cleaner. I let it soak for 15 minutes then flushed it out with a hose, in the reverse direction of the exhaust flow. I repeated the process and again flushed with the hose. I then used my high pressure cleaner from both directions and stood the chamber on its end to dry.
I refitted the chamber and drove for 8 kms at 3000rpm to dry it out. The engine management warning has gone, the engine light is out and it runs better than it ever has.
My options where $6500 to replace the DPF, or 2 hours labour and $15 for some caustic.
All 4 bolts holding the chamber to the exhaust broke! No big deal I drove them out and replaced them with some 7/16 316 I had laying around.
I have also found a company that will re tune the ECU to remove the DPF and improve performance etc.
