Just to report. My Yeti had It's first MOT last week. It sailed through. That is after almost 8200 miles in the 3 years! NO, I have not had DPF problems from doing the 2 mile return trip to the village shops.

There will be even less with the Euro6 ones I expect, due to there being less emitted into the DPF.

I thought the AdBlue/SCR system was after the the DPF so all particulates still pass into the DPF.

 

However it's the early DPF filters that were mounted as an ad-on further down the exhaust pipe (too cool and sensors exposed to the elements) that had major reliability issues, especially the ones attached to VAG PD engines which due to the cam driven Pumpe deuse didn't work well with a DPF (not great for active regen). Later close coupled common rail designs much much better.

My understanding is that the higher burn temperature results in less particulate product to have to deal with via the DPF.

The use of DEF is to reduce the resultant higher NOx by ~ 90%.

Plus more efficient extraction of energy from the fuel with ultimate cleaner exhaust AND better economy/lower CO2.

All good stuff but politically too late to save diesel from the public's wrath.....perhaps.

Battery for inner cities looks inevitable.

I've only recently become aware of a separate DPF treatment fluid that Peugeot use and is only able to be topped up via one of their service outlets.

Mine also passed its MOT last week.

Emissions were-

CO. 0.00% vol

HC. 1 ppm

Do you mean SCR fluid (i.e. 'AdBlue')?

No

Its a separate fluid in a separate tank adjacent to the fuel tank, not accessible for topping up purposes other than via a dealer servicing division.

 

Oooer! I'm glad I have a Yeti!

If it's done regularly you would be good at it.

I would expect the DPF to last longer and save a packet that way.

Latest Peugeot/Citroen cars use the adblue system I believe.  The previous Eolys fluid system used a thick sticky liquid installed in a bladder inside a box mounted under the floor.  But these only needed replacing every 50000 miles or so,  and it was done as part of major service....usually.  Unfortunately the bladders occasionally leaked red goo all over the underside of the car (and your driveway), requiring premature replacement.  I guess they've ditched the system now in favour of adblue,  but there are millions of dodgy bladders out there somewhere!   (OOH err, Matron!)

The old ones you refer to weren't AdBlue equiped.

The current Peugeot diesels are now fitted with a filling point inside the filler flap and even then probably not needing topup either.

The AdBlue is prior to the catalyst and the 'regen' fluid prior to the DPF (replacing overfueling).

Every day is a school day - I'll admit I wasn't aware of this DPF/Eolys fluid thing.  After a bit of research I am glad I don't have to use it as it appears to use cerium-based which has some questionable toxicity, both in the fluid but also as an airborne particle post-combustion.  I shall endeavour to overtake any Peugeot diesel I encounter.

Hmmm

I already do...
