I don't have any issues but was wondering if it is possible to see the current saturation of the DPF filter with OBD eleven. I would be interested to see what it says. If you can is it displayed as a percentage?

Can you get any more information like last regen time?

Is there a light that displays when a regen is taking place?

Its possible to display something like this, maybe more:

Thanks don't know how I missed this. I think I was searching for DPF rather than particle filter. For anyone else goto your car in OBD eleven garage > Control units > Engine > Live Data. There are quite a list of particle filter counters under there. Does anyone actually know what any of them mean? When the superb is doing a DPF regen is there any indication it is doing it? So you can make sure it completes before turning the engine off.

 

There is no indication that a regen is taking place.

 

You might notice a slightly higher idle or a drop in economy but that's it. It's fine to interrupt a regen, the ECU will continue if it needs to. As long as you're mostly doing journeys that are long enough to get everything up to temperature, it should be fine

 

As for the data, soot is what the DPF catches. There is both a calculated (by the ECU) and measure (by the pressure sensors) level, when it's suitably high, it'll cause a regen to occur. The soot level will then reduce but there is residue left over, mostly from burning small amounts of oil, which becomes oil ash. This cannot be burnt off and will determine the lifespan of your DPF.
