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...

...any leaks. However what I have noticed is that when I'm driving the 'Particle Filter, diff pressure Sensor 1 bank 1' (which I assume is the pre DPF sensor) reads approx 20-100mbar but when I'm at idle this drops to around 1mbar which is less than Sensor 2 (I assume post DPF). Surely the...

...etc IGN ON, then cold start (5 degrees) Lumpy :/ Log-03 IDE09327, IDE09328, IDE09329, IDE09330 etc Durning my drive to clear lumpiness, the DPF started doing a regen, and the idle and acceleration felt more lumpy. So pulled over and done this log, unsure if it will show anything, maybe I...

...and have code P2463. I’m waiting for the arrival of a Carly OBD scanner which I think allows me to force a regen… But I’m wondering if the DPF is blocked… why don’t I get the DPF light showing on my dash and instead get the flashing glow plug light and P2463 error code. And what causes the...

It shouldn't - I wonder if the previous owner who had the Adblue mapped out also gutted the dpf?

Ahh, yes, the EML might be on as it wasn't able to do a DPF regen due to the low Adblue level? If so, then your adblue is correct, mine also shows 6000 miles after filling it. So take it for a long drive and let the DPF regen happen then you should *touches wood* be good.

I have a question or two. I have an old t5.1 CFCA 180 BiTDI (DSG 4motion). Retro Resus fitted a new DPF in 2023 and blanked and mapped the EGR and watched the oil consumption rise over the next few months. Spring 2024 new VW create engine, turbos, flywheel etc. 8k miles now on the clock and...

If they can't force regen the dpf, then it won't self regen either. I would be trying to spray a dpf cleaner into the dpf, but I'm guessing you won't have any tools or a friendly garage to help you with this. If you were able to locate the dpf pressure hose before to dpf and remove that, then...

I think it’s well proven that is not the case. DSD do market an empty DPF (off road use), the cynic in me says they have a batch sat in a shed to shift. That said they also specialise in re-mapping, if the map is for higher output that requires a higher gas flow due to increased fuel...

You need to look at the dpf differential pressure to see if it has the internals in

This rings some bells - the pressure drop goes up fast after regen and evens out when more soot accumulates to pores: https://www.t6forum.com/threads/t6_measured-01-engine-built-in-test-for-egr.42060/post-591031 I would think if large part of the comb would be blocked even after a regen, the...

Would the only reason it won’t start, if the issue is DPF, because the dpf is blocked? Is it not possible just to remove it and see if the van starts? Or is it not that simple?

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

I’d be inclined to get the DPF removed and backflushed.

That I believe is the dpf light. This night help

Just to add and forgot to mention, it has apparently had an adblue delete by the previous owner too. If dpf blocked would there not also be a dpf light illuminated as well as the yellow coil (limp mode) lamp? Suppose this is the joys of buying a used vehicle with no real knowledge of what has...

Sorry no. It was before the rebuild and i wondered if that has filled the DPF up. Thanks

I believe they use a charge cooler and may be hard pressed to change. As regards as sports cat, good luck finding one. Not sure what real benefit you would get from that anyway. DPF delete will get you some extra horses

...soot mass measured should be climbing - not as fast as calculated but noticeable by every mile. Have you tried other engine group options in VAG DPF - if any of them shows more meaningful (non-zero) values. No, it's not related to soot mass calculated/measured . I would say the...

Occasional low fuel, but no dpf light.
