Adblue use after DPF delete

[Steviesam]

If a car has a DPF delete, will it still use Adblue (unless that is deleted too)?

Thanks

Yes. It is also likely the SCR system won't work for long either because the soot that should have been trapped by the DPF will now end up in the first SCR catalyst, which it won't be happy about.

[Steviesam]

Thanks. Is the SCR system the one that uses Eolys fluid (PAT)?

[Megaflow]

No, that is part of Peugeot's odd DPF system, nothing to do with SCR.

I really do hope that all these dpf ‘deletes’ are caught by stricter MOT testing or roadside tests.

Have a look at incoming EDAR cameras.

I have seen that mentioned before. I have also seen our exhaust gas analysers at work that are Euro 7 capable.

To think that camera can measure to the same standards is frankly laughable. To then be able to identify a single car from a crowd is even more laughable.

Mine is still complete and working just fine, so you can sleep well tonight.

Why bother asking?

Isn't DPF delete illegal?

I didnt think anyone would be interested in the detail, but I asked because the diagnostics says that its been 4096km since the last regen, and that number does not go up when driven. So I initially thought that maybe the DPF had been told not to regen by way of doing some sort of trickery with the ECU, and it is still using Adblue. Hence the question.

However, having been under the van this morning the DPF is still there and after tapping with a hammer does not sound hollow and looks orginal. So it is there, which means its still working because if it was there but had been remapped to stop DPF "stuff", it would be blocked in short order and have warnings etc.

Curious. DPF regeneration processes are massively complicated and cover all sorts of variables. That said, I'd have expected something like km since last regen to increase with actual km's.

Sounds like your DPF is there from the hammer test, and if it isn't throwing codes I'd leave it.

Love the way we can spend millions on technology to further rinse a motorist.
Have we given up on crime as a lost cause and let’s make money instead via the nasty motorist.
Need money? What can we increase on motoring then!
Just like Liverpool council who’s skint, let’s get it from motorists then. Increases of up to 60% on car parking.

This.

Span gas supply tubes have to be micro polished to prevent entrainment of molecules. That's how sensitive the Analysers are and they sample direct from the exhaust pipe with defined dilution.

The fact the article states "Does not need calibration" is also ridiculous.
