Technical 2017 2.3 130 / DPF differential pressure range

[mikegolf]

Hi, I have 2017 Ducato 2.3 (130 PS). I'm looking for an information what is a normal / correct range of DPF differential pressure readings, both on idle and under load.

I'm reading 12-14 mbar at idle, and up to 260-270 mbar at heavy load (accelerating on an uphill road, at about 3-3.5k RPM).

I'm looking for the reason of misbehaving turbo, it eventually reaches the target pressure but only at about 3k RPM. The system seems to be airtight, and the turbine itself has been checked at the regeneration shop, they claim it's good. This makes me wonder whether my DPF is clogged.

Those figures are indeed high.

I would try some DPF cleaner.

Mine is about 2-3mb on idle and 70mb on acceleration.

Is your pressure sensor reading correctly and have you blown air down the pipes to check there is no water in them?

Hello @mikegolf

I’ve just watched this YouTube video of a 2017 Peugeot Boxer with EML on that turned out to be poor pressure sensor connections, but within that video live DPF pressure readings are shown which are not dissimilar to those @Googlebot has posted.
