DPF Replacement or Refurb?

michaels

So I have a diesel, we do almost entirely short trips, so of course the dpf has become clogged beyond regeneration.

The options seem to be a specialist refurb for about 300 quid or a new one for between 220 and 370 plus fitting.

Does anyone have any experience of how successful either of these options are. How about any way of knowing which price replacement to buy - are the more expensive ones better or just someone making a higher profit?

£220 seems cheap for a new one , i would get a new one for that price

Once it's fixed trade the car in for a petrol model. Any fuel savings you're making will get eaten up by DPF issues.

if you are going to keep the car then spend the money and fit a manufactures original DPF, with the DPF it really is buy cheap buy twice

DPF,s are becoming more of a problem and it will only get worse as more and more of theses DPF,s fail due to the way the car is used

last year the way to go seemed to be gut the DPF and have the car remapped to eliminate the DPF, but the visual check of the DPF has now come into the MOT test, this said people that have the empty dpf can in place have still passed as it is only a visual check, the people that removed the dpf can and fitted a straight pipe are the ones that are falling fowl of the new MOT requirement

and as already said the prices that you are quoting do seem very cheap

Take it to a local garage and have the gut the thing and re-weld it back together. Then see where you are emissions wise come next MOT.

For work I drive one that's had this done and it passes emissions every time (and they are required to take an MOT every 6 months).

The replacement at those prices is likely to be a pattern part.

Pattern DPFs have a tendancy to be less robust than OE ones.

The two companies I know of are DPF Genie and Ceramex.

I wouldn't use any other way of cleaning a DPF than those two.

Who has told you the DPF is clogged?

Main dealers tend to advise replace when a simple clean of the Ash is all that is needed.

Note the ECU is not able to tell the difference between Ash and Soot.

Ash is a by product of regens there is no getting round it.

After you get it cleaned you could try one of the over the counter DPF cleaning products.

The best in my experience is JLM DPF Cleaner which makes regens easier in a similar way to Eloys Fluid in some Fords, Volvos and PSA Group vehicles.

No over the counter cleaner that goes in your tank will get rid of Ash.

You need DPF Genie or Ceramex to do that.

Both of who guarantee the service and test the DPF to see how clean it is after cleaning.

I have found my car needs less Regen runs with the orange light on when I have used Mobil 1 ESP. Why? I don't know as the Saps are the same as the other oils used by me and the dealer.

Good luck with it anyway.

The issue with this it isn't just a case of passing emissions tests.

This is now a Construction & Use issue.

It is possible that an Insurance Co could refuse to cover your damage in an accident for that reason.

I don't imagine a gutted dpf causing or contributing to an accident.

I think the point being made was if involved in an accident the insurer may decide it is classed as a modification and if undeclared void the policy

I appreciate the point being made. How would this modification contribute to an accident?

But an undeclared modification would not need to contribute to an accident. If they would not have insured the car with such a modification, they could void the policy if they found such an undeclared mod after an accident
