Excuse the dumb question, but one that's puzzled me for a very long time, what happens to all the soot and particulates "stored" in the DPF during the regen process? Are they just shot out all in one go, are they converted into something that's not harmful in any way, or does something magical happen to make them all disappear? If the former, does that mean the nasties continue to float around for us all to ingest?

When the DPF regenerates actively the dpf heats up to around 600 C and the soot particles burn off leaving an ash. That's why low ash oils are so important in diesels with DPF's to minimise the amount of soot in the first place. On the cars I've had I've never experienced an active regen as they all did mainly motorway work so the DPF worked fine with passive regen

DPF Info
When I got my current car a Saab 95 (getting an E320 Sport next week:bannana
I had endless issues with the DPF, some of which I now suspect I could have avoided, came close to either swapping car or having the DPF removed and ECU re-mapped neither of which I wanted to do. In the end the problem was fixed. However I did come to the conclusion that a bit more info might be useful.
In the Saab handbook it says that when it wants to regen you'll get a warning on the dash. That never happened and I understand that's a common scenario...
So what would I like to know?
Hoping the E320 is better behaved then the Saab 95.

So what would I like to know?
- What the contamination level is in the DPF
- What the temperature is in the DPF
- Explicit indicator that it is regenerating

[*]What the contamination level is in the DPF
[*]What the temperature is in the DPF
[*]Explicit indicator that it is regenerating
The above would enable adjustment to driving style (conditions permitting) to allow the system to do what it wanted and best of all if the manufacturers thought about this they could provide this data easily with no more instrumentation. The cars systems have all this data why cant they send this to my phone?

The e320cdi sport won't have a dpf.
