Have you had a diagnostic check done?
Get one done and post up the faults here and I'll be able to help you.

I have a 1.6 2005 407 and i took the dpf off the exhaust systems yesterday, but am not sure what to do now with it whether to chop off the filter and replace it a stainless steel pipe or drill a hole straight through the filter itself and put it back on. I would be greatful for any ideas or suggestions as can only find bits an pieces online no straight answers

First of all why did you remove your dpf...?
Is it flagging dpf related faults..?

If you had diagnostics ran on your 407 and all your dpf related sensors are o.k. but your filter needs replacement then...

Imho you have two options..

1)Fit a reconditioned/cleaned dpf or clean your own dpf.

2)Remove your dpf totally and remap the engine ecu so it will not initiate a dpf regeneration when requested by the engine ecu.

If you do go down Option 2 make sure you get someone who knows what they are doing...I have seen so many companies attempt to remap these 1.6 hdi without success....:rolleyes:

I have cleaned alot of these dpfs by running then tru certain process which brings them back to there original state...:D

With all diesels been fitted with dpfs from 2011 i personally think the Nct centres will bring in a soot test in the future which may cause a lot of problems for people who removed there dpfs in the past....

No did not have a diagnostic done on the car says it fluid additive too low so went to main dealer got quote of 450 to refill and start regeneration cycle. i just felt thats a little pricey. i am kind of handy around cars and good friend of my is a mechanic so no worries there plus i work in a metal fabrication shop so chopping out the filter was not going to be a problem, this was kind of the main reason i went down this road. but as you said i have two options. this is why i stopped at just taking it off a decide to join boards and ask around. its funny i was hoping to get talk to you row as have read some of your threads and you about the only one that seems to know what your talking about. any advice would be great

Thats nice, I can see loads of helpful advice coming now: rolleyes:

rumbb

Did'nt mean it that way from what ive seen row does more answering then asking thats all. Did'nt mean to offend anyone all advice and suggestions on the subject will be taken on board

dieselbug

No offence taken, just having a little pop

Additive low could mean it just needs topping up. Not a big job. The additive fluid is expensive. I think I paid about e150 for three litres last time I bought it from the main dealer. It needs to be handled carefully as it's nasty stuff h&s. After filling the control module counters have to be reset ie the computer has to be told it's been filled.

I wouldnt be for removal at all. I find these Peugeot ones are fairly reliable with proper servicing and as long as your driving style is not all short journeys they are not likely to give many problems.

Unless the warning has been on for a very long time there should be no need for a forced regeneration. 450 does seems a bit pricey unless the fluid has become very expensive recently.

You may as well clean the filter now that you have it off.

Best thing to do then is put it back on and get the additive topped up by an independent garage with the appropriate equipment. Then you will have many more miles before you ever have to worry about it again.

If Peugeot only quoted you for the additive topup then my guess is they will also recommend you replace your dpf which could cost another 400 euros...:eek:

What mileage/kms is on your 407...?

If your handy then you could topup the additive yourself but you will need diagnostic equipment to reset the system.
If you purchase 1 litre of additive (eloys fluid) it will cost around 70 euros but you will need a filling kit to top it up.
If you purchase 3 litres of fluid this will come with the filling kit....this will work out around 140euros.

I usually purchase this fluid from Citroen as they can be alittle cheaper than peugeot....:)

Once you top up the fluid and you get the system reset then get them to check differential pressure across the filter,if its fine/clean then you should be good to go....if not then you will need to replace/clean your filter.

Is there a diy method of cleaning out the dpf filter George?

Technoprisoner

you can buy the additivie from motor factors for a lot cheaper than that....if i remember correctly its about €100 or so....dont hold me to that price though...thats just off the top of my head

This guy Ben is a regular over on the BMW forum and has his own DPF cleaning service. Haven't used him myself yet but have heard nothing but good things about over there. When the time comes I will be using his services, he is based in Co Clare but offers a shipping service.

Resetting the additive/dpf system should cost around €30-€40.

As for cleaning dpf's this is the way I do it...:)
1) bake the dpfs in a furnace @700 degs C for and hour or so which burns and clogged soot into ash.
2)I then remove it (glowing red..:D) and wait till it cools alittle..then blow it out with compressed air.
3)once it cools down totally I then power wash it from both sides which washes the filter out fully.
4)I then blow it out again with compressed air again to purge out the water and pop it back into the oven for and another hour @350 degs C to dry it out fully.

This process hasn't failed me yet..:)

I have a cleaned/reconditioned dpf for a 1.6 hdi in the garage atm.... I take in old blocked dpfs in exchange for cleaned reconditioned units.



You could power wash it yourself but ensure its well dry before you refit it.
There are also solvents available in most auto factors which clean dpf but not sure how good they are..

Best of luck with it...;)

George Dalton

Wurth do a cleaner that is pretty good, a lot of motor factors sell it. It is probably the best option for a DIY-er as a preventative measure when the filter isn't actually blocked.

rumbb

to be honest my filter doesnt look too bad there was no build up of or no real sign of sooth on the filter when i took the two halfs apart. but just to know anyway how much would you be lookin for the swap. i would have no real access to a furnace or any real way off getting the filter up to 700deg.

Its difficult to know what condition your filter is in unless view the differential pressure across the filter via diagnostic equipment.

I'll pm you a price for a reconditioned dpf but it does take energy/time to clean them this way.....The main costs involved is getting the dpf's up to such a high temp and the time it takes to heatup..cool down..powerwash...dry out the filter ready for fitting.

rumbb

I mite have a way of getting the filter up to 700 well im going to give it a shot and see how i get on. i build a forge a few months ago going to make a few alterations see if i can close in and control the heat from the forge and try not to blow myself up in the process ha ha

Technoprisoner

a blow torch and compressed air should get it up to those temps

Fiskar

How about getting a good hot domestic stove going with coal and popping the DPF in? Surely that would burn the ash out?
