How to prevent dpf blockage?

daylers

Is there any way to prevent dpf from blocking? Is it caused by dirty fule or driving style or will it just happen no matter what ?

A good trashing every now an again! That's the problem with people buying diesels for the school run.

Depends on the car too. If it's the 1.6 psa engine it'll happen anyway.

Once you drive the car on trips that a diesel should be driven on its fine. Once your doing a bit of motorway driving and long trips it's fine. And if your only doing short trips around town then you shouldn't have bought a diesel in the first place. Used under the right conditions dpf can cause no issues upto at least 250-300k km. my mother has an octavia for 3 years now from new 1.6tdi with dpf over 100k km on it now the dpf light has never come on, it's never caused any problems or impacted the car at all so they are not as bad as people make out.

Driving style is one reason for dpf blockage but not the only one.

If any of the dpf components become faulty or any engine releated functions necessary for sucessful regens are not correct sucessful regens may not take place.

I have seen many psa 1.6 engines with dpf and high mileage that have never given dpf problems especially in 407's.

Like all things, proper serviceing is important, using the correct spec engine oil and not ignoring the warning message on the dash until the car stops.

Not all 1.6 hdi PSA engines have a dpf!

Drive a diesel car as it was intended to be driven and there should be no problems. Constant short trips will eventually kill the DPF because the engine ain't running at an optimal efficient temperature long enough for the DPF regeneration cycle to do it's job - burn off the particles and soot that a diesel engine produces. If this these particles and soot are not burnt off then they just build up until the entire filter system is blocked.

You could pay for a Terraclean to clear out your system too.

Probably best to sell it and get a reliable and clean petrol engined car.

Thrashing it is no good really. You could drive around town all day doing this and it would do no good. You need to take the car for a 15/20 min drive with the revs just over 2,000. This generates the required heat and time to complete the process.

I thought it had to have higher revs than 2000?

Any idea how much this costs for a diesel?
Looks interesting! Have you had it done and if so did you notice a big improvement?

Do most of the 1.6 psa's have a fuel additive bottle - between that and the correct grade oil and a good motorway blast once a week or so should see you right -

Afaik they have a separate tank to hold the Eolys additive that is used by the DPF regeneration system.

Haven't had it done but did look into it.

I think there are different forms of it. One for the engine, another for the DPF system etc.

Think I saw a price of £120 for engine clean, and £180 for both.

a good lash of DIPETANE and drive the sh1te out of it

I seen a poster outside a local auto factors the other day for Dipethane, had no idea what it was.

Must look it up.

Mine will do a regen driving around town.

Aye, but Borrisokane smell like shyte when you do

Fey!

We bought a 1.6 Picasso recently (ended up with diesel as there were no petrol ones in a decent spec on the market).

If you read the manual it tells you that if the dpf light comes on, that you should drive the car at 80kmph for 20 minutes. I find that this does work.
