Diesel Particulate Filters

[Gazza77]

I'm looking at swapping cars, and the ones I'm currently contemplating have dpfs (Nissan X Trail 2.0 dci to be precise).

I know that most diesels nowadays have dpfs, and that due to the need to regenerate that "short journeys" aren't recommended as the main type of use, but what constitutes a "short journey"? My daily commute is a 32 mile round trip, using mainly B roads, and up and down dale as I live in the pennines. I also tend to do regular short runs most days of about 2 mile round trip to go to the gym after work, although the outbound of these would still be when the engine was warm as I tend to just nip in home to get changed on the way from work.

Has anyone with experience of modern diesel engines any thoughts on this?

they are getting better as to when they first appeared on diesel cars. not all have them AFAIK. they are used to lower emissions and so lowers road tax. They need to be refilled on an every other service basis usually (depending on how large the reserve is) and they do charge extra for this at the garages. tbh by the sounds of the journey you'll be doing it should be absolutely fine. diesels are just no good for when it is constant low speed driving, stop start around town and short trips where the engine can't get up to temp.

You'll be fine with that sort of use.

Mine's clogged-up once after a long period of short journies. 80mph blast in 3rd/4th gears cleared it fine.

We got an email from Masterlease telling us that if you're DPF get's clogged, you have to pay the £2k fee to fix it.

They are the reason I have avoided buying a diesel. I fancied a new 5 series diesel but only do 8 miles a day most days. The diesels were also 3k more for the same spec etc. Ended up buying the 4.5 v8 petrol instead. No turbo, no Dpf and it does 22 mpg round the doors, lol.

Obviously this is a massive derail, but on reading about the amount of ****e that can break now on a modern diesel i just couldn't risk it! Petrol is also cheaper to buy and service. Do you do a lot of miles per year?

You can't get petrol T31 x trails. Only a few petrols were sold so they stopped importing them

[Jackie_Black]

Ah see, fair enough. To be honest a nissan diesel should be fairly bulletproof, although my mate used to run a fleet of navaras (don't know if they share bits) and they were a lot of hassle.

[NTECUK]

Nope navara have yd 25. And the t31 is a joint Nissan Renault engine.
The D 40 navara is well sorted now .the v 6 one is smother than chocolate :)

That's rubbish.

I was quoted circa £200 for the dealer to clear it by running a preset regeneration cycle, but they advised me to try the morotway thing first. Struck me as very honest advice. Oh...... '07 reg Mazda 6 2.0TD (143bhp engine).

be aware... our 07 plate mazda 6 just went bang at 70k.. whole bottom end has gone, no warning signs nothing.. just clunk bang.

I have only ever changed one dpf. And that was due to incorrect oil used by a non franshIse service using the wrong oil.and over filling the engine..
Never had problems with navara qashqi note etc .
The newer ones use active er Gen, so lots less hassle for the owners.does it for them so they don't need to Di the motor way thing anymore as they don't fill with soot anymore.
