Vans, diesel engines & DIESEL PARTICULATE FILTER (DPF)

Midwest · Feb 13, 2018

This subject has been mentioned before (wirepuller talked of it), but it won't hurt to mention it again (Fawlty Tower Style!) for those thinking of a new van (or car).

I've been looking for a new used vehicle; was thinking of getting some sort of Chelsea tractor, one of which was a Discovery Sport (DS). After reading about it on a particular forum, it appears to have an issue with the above.

To meet Euro 6 emissions (I'll stand to be technically corrected), a DPF is used to trap some of the nasty stuff. In the DS's case, its a bit of a challenge, and requires some mileage driven at a certain speed to do so (as do most such vehicles). Put in a short journey when it is attempting a regeneration, and turning off the car dumps some fuel in the sump, causing another issue, oil dilution.

Too many failed regenerations, will require vehicle servicing or even possibly repairs. The oil dilution is another problem.

So those buying/leasing new diesel vans would be ok, if they do some mileage, those doing short journeys might wish to reconsider the fuel choice for their new vehicle.

This guy had to sign a waver when purchasing a new diesel Ford Connect (Zedman);

Problem is that a lot of those chelsea tractor are brought for nothing but the half a mile school run and maybe the odd local journey. DPF work well when your regularly doing long motor way miles but short low speed driving fecks them, but to fair they should be making buyers aware when buy the cars.
