First I bought one of these:
VCDS lead off Amazon
which measures everything. The Measuring Blocks you need are:
Once installed Select 'Engine', then select 'Measuring Block' and the block (numbers) you need are here:
Group 75
1. Turbo Temp - useful for regeneration
2. Temp before DPF - useful for regeneration
3. DPF load coefficient - no idea what this means
4. Temp after the DPF - useful for regeneration
Group 68
1. DPF Load Coefficient - same as value above, no idea what it means
2. DPF carbon mass (max 60g) - this seems to be critical. It has a max value of 60g.
3. Carbon Mass Learned Value - I believe this is the correction factor you need to put to the value above.
Group 70
1. Regeneration Status - self explanatory
2. Regeneration Time - self explanatory
3. Failed Regenerations - ditto
4. Successful Regenerations - ditto
On my DPF I got a carbon mass of 54g (max should be 60g) so I am guessing its near the ends of its life.
I am assuming the graph above measures the 'carbon mass' - does anyone know?
I also found out that the actual life of the DPF = Carbon Mass - Carbon Mass Learned Value. So In my case = 54.52 - 14.6% so = 39.9g - is this correct?
Or the other way I worked it out is that the ACTUAL carbon mass value is 14.6% out of the 54.2g so that means mine is at 46g (equals = dead)

Now...
Taking Rosstech's regeneration info:
http://wiki.ross-tech.com/wiki/index.ph ... generation
Regeneration of DPF happens only between 30g and 45g - beyond this it won't.
I am guessing mine has passed its life. What I can't understand is why there have been zero successful regenerations.
Hope this helps as a starter and welcome people's thoughts on whether this is correct and what I could do to my DPF (please don't say gut it).
