I was explaining to you why I had to zero out the ASH value
I'm not sure what you did - or what you think you did - on a non-Touareg engine. But I know that in Touaregs
1. soot and ash levels are administered separately, ash levels only increasing, never decreasing, and going well beyond 45 grams and even more with time
2. automatic regenerations of the DPF are halted by the ECU if the soot volume goes beyond a specific limit (which is measured in volume, not grams), regardless of the ash load
3. to do an emergency regeneration you don't need to "zero out" any of the ash or soot levels, just set an appropriate flag in the ECU, which essentially overrides/disables that check explained in 2., and initiates the procedure anyway, and
4. that it would not make any sense to initiate even forced regeneration of the DPF if it would be really the _ash_ level that goes out of bounds, because regeneration would (physically) not be able to decrease the amount of ash in the DPF, and this not solve the problem if there being too much of that in there.
Add to that, that the graph you've included (and which is obviously not for a Touareg engine and/or DPF) is also talking only about _soot_, and doesn't even mention ash by any means - which also implies, that if you went by that 45 grams limit and you've really zeroed out something that was above 45 grams, then that was almost certainly - and contrary to what you say - not the ash, but the soot value. Because, well, if the value you have zeroed out would have been the ash value, that still would have left the soot load at or beyond the supposedly allowed 45 grams limit, and thus still hindered even forced regeneration of your DPF, wouldn't it?
Talk about being confused about technicalities.
