DPF differential pressures & other info

Hi.

Puma 2.2 MY 2014, 28k miles.

Been having a few concerns about my DPF. Had a specialist around with all the kit.
Differential pressures were very low (1.7%) but DPF showing around 70% full.
Specialist said that this is fine as pressures are low.
Bought some fuel additives - WEPP 2132-300 and BG 245 from the same guy.

Will see how these go but have been thinking about getting one of those bits of DIY plug-in kit that gives you info from the engine management system.

I think they’re widely available but not sure which ones to look at.
Can anyone give me any pointers or advice?

Thanks.

Not sure exactly what you mean by concerns..given your differential pressure is low..
We had a discussion on this topic a while back on a thread and think its safe to say you don't want to be getting wound up by the scan tool data on % soot loads as long as you are regenerating and it falls ..
The pressure across the unit is a far better guide ..
My torque app did give temp readings on the exhaust but sorry I can't remember if it gave the differential pressure data..it is listed in the data available , but can't remember viewing it..

DPF fills up and burns out : 20 ... 90% in one cycle
That's for normal use.

You're @28K - so your DPF will be fine for another 100K - at least

You cannot deduct its life expectance from sensor (ECU) data.
But you may display these data with a Nanocom.
