Thank you very much for your detailed analysis. In summary, the DPF displayed mpg figure does include the extra fuel used for a DPF regen, but the displayed figure spreads the extra fuel used over 60+km more than the actual distance of the regen (~20km) in order to reduce large fluctuations in...

I'm in Ireland..2018 bi turbo doing very short journeys. Had egr delete and dpf gutted. It won't pass NCT test now it's equivalent to MOT. Will I need a new dpf and if so how much do they cost

Because Im kind to my DPF I never let it go below 1/4, but I guess I can filled up from 1/4 and add a third.

Welcome @Gilkesy I'd be investigating the DPF issues first. It might just be a case of regens not being done or it may be a symptom of much more extensive work being needed that might make the "cheaper" fixes moot. What is the indicated soot level in the DPF?

Ooooh that would be very good. And regen in progress! Could this be requested from the manufacturer @antony.charnley ?

It was @mmi here in this thread https://www.t6forum.com/threads/dpf-regen-questions-concerns.53409/post-698717

Have you checked the soot gram value in mvb’s with vcds? When you say a flush.. have you physically removed the dpf? Did you carry out a forced regen of the dpf following that?

From observation using VAG-DPF (not the extensive data logging of @mmi) I'm certain that a T6.1 doesn't complete a regen at idle but gives up at around the 5 minute mark. I still let mine run on though as my assumption (hope?) is that controlled pause to regen is not going to be dumping diesel...

Worth the £37 a month then... o_O

Hi folks, looking at the soot measures vs calculated amounts, the minus figures is puzzling me? Should I have rest the dpf in any way after completion of the forced regen? Or would this munis fugue suggest : A) a sensor is at fault B) previous ownswer has changed dpf settings to try and hide...

So do you think the waste gate is opening when you drive it hard? Edit; hard to know if the reduced gas flow through the exhaust due to defective DPF would reduce the turbocharger speed enough to reduce boost pressure. You mentioned elsewhere it’s a new van (to you), I wonder if it’s possible to...

How blocked was the dpf when you had it off the van? Had an Audi A6 3.0 quattro dpf that a filled up faster than it emptied with a hose pipe. No idea how it even managed to run the engine at tickover. Only thing that worked was having it properly cleaned.

...possibly there’s a hole, back flushing will just go the path of least resistance. Different opinions but I believe that back flushing the DPF is a very bad idea, the DPF also contains the SCAT which may be affected by the chemicals. IMO the only fix is a replacement DPF BUT you need to...

Maybe diesel dilution in the sump? Dpf clogged? Egr full?

DPF Pressure Sensor - 04L906051AB I would say it's sooty, pictures attached.

Nice one, im IOs so will have a look, be good to see if this is related to DPF regen and temps!!

It's designed for continuous monitoring of the DPF state when you're driving and tries to surface all the counters. That's for Android there's a similar app for iOS DPF Monitor for VAG Both just need an OBD dongle to work - the Carista one will be fine. You then need to do a bit of fiddling...

Personally would be looking at the DPF if you are still getting problems. They are a massive ball ache. Hope you get it sorted.

No fuel low warning light on dash? No DPF light on dash at all?

What's the solar set-up? Any suspension changes? Had any of usual issues with DPF and EGR?
