Sorry to hear your tail of woes I have a 204 CXEB with the DPF off at the minute, the measures ash level was 76g. Once I eventually go it off the van, I run a hose pipe into it, filled it up completely with water with only a trickle coming out the other end, an overnight soak in Wynn's DPF...

That's exactly what I had done a couple of years ago. Done maybe 20k miles since. DPF regens are currently about 150 miles local driving and 225 on a long run.

Thanks again for your time! So as I understand… I may be wrong… EGR is good, DPF, is good, turbo actuators are all good… So we’re looking at the remap as the possible problem as it’s asking for too much boost?

If you are on Android there is VAG DPF (which I use) or on iPhone DPF Monitor Long thread here of some suggestions and comments: https://www.t6forum.com/threads/best-dpf-monitoring-app.23342/ One thing to note is that as the DPF is cleared by increased heat counterintuitively if you work the...

Why not just wait and see what happens with the DPF and if/when it starts playing up, weigh up your options then?

ahh for Android there is another, sorry I cant remember. There is a thread here somewhere with info. Search DPF app

Dpf regen run by engie ECU. Uses throttle body to control air inlet and turbo and EGR to adjust airflow. And injection timing to add fuel to outgoing exhaust. All combined to increae dpf temp. Various pressure and temp sensors used.

There’s a calculated ash value in the ECU for the DPF. It has a limit set, I forget what it is, but when it reaches it, it’s dpf replacement time. I’m sure there are other values also measured that trigger it too. 30k seems low, but my neighbour had a 110 he used to deliver Amazon parcels, lots...

I had the same concern but was assured by the tuner it would regen as before. I believe this is because adblue injection is post dpf? I’ve been monitoring it on the dpf app, though the frequency is less than desirable when it does regen, the soot mass does drop to the required value.

...km to 238763 km = 184 km, 2 hours. Plotted the two soot mass parameters (calculated & measured) which are used by ECU to monitor and trigger DPF regeneration. Normally "soot calculated" (blue) is the dominant one. Here it's a kind of opposite. As soon as "soot measured" reaches the DPF...

Hmmm.... but the DPF and EGR were deleted? Catalytic converter still in place? I guess the smell is only engine idling (would be difficult to sniff otherwise?)

I may be wrong but on my van whatever I've tried, it has never passively decreased the soot in the DPF. It always goes up, 0.1g at a time. Might be a little slower, but still up up up.

@mmi This looks like a great opportunity to get some DPF differential pressure data...?

It's on the suggestion board. Perhaps they will in time?

From personal experience you’ll get DPF problems from using van as a daily. I use mine as I would any car, long journeys now and then. Thought mine was regen but it wasn’t. I started getting the coil light and going into limp mode, 4-5 months went by, no one could figure out what it was. The...

Darkside won’t do it without a dpf delete as well. Speak to Chris @Dav-Tec

Update! I don't see enough updates with resolutions to DPF issues, so thought I'd post one! Decided to fork out on a garage that specialises in DPF faults. They diagnosed one of the temp sensors was throwing up crazy values and throwing off the ECU. It was showing 700c one sec and 100c...

When I looked into this darkside said I would have to remove the dpf. So I went down the tafmet route instead, 20km with the tafmet fitted no issues and dpf regen as normal. It may the way tuners program out the egr is the only thing I could think that would stop the regen process

I got the DPF in France Second hand but brand new in the box (with matching numbers) for €700.....maybe a mistake as no warranty. I am going to stick my borescope down this afternoon and have a look for visible damage.

Yes, obviously the filter is not filtering as supposed to. The fault is triggered by the soot sensor after the DPF. Well, just a hole/crack wouldn't explain that. However, the DPF being clogged would have explained poor fuel economy causing too intense DPF regens. The values in your screenshot...
