Anyone done this?

My 1.9JTD needs a new one so its coming off. Need a remap to remove the regeneration bit..

Any recomendations?

why do you need a new one??
if its blocked why try regeneration or remove it and clean it (steam clean)

Sorry to hijack, but can you manually get the DPF to regenerate (Ford 2.0 TDCI)

Steve

I know Pendle Performance does dpf delete. I think once they have got to a certain point in their life they are goosed so need replacing or removing

no steve its a set program where the car is over fueled and so run at a hotter temp to burn it clean. if you can remove and clean. have done this on a few psa deseils with some results. would suggest high pressure steam clean

My commute is 1.1 miles each way with 12 hours in between, then maybe 1~2 short motorway trips a year. Around 5~6k is what I average. I dont do enough miles for it to regenerate.

That aint enough to keep the DPF in good order plus I'd rather have a freer breather more economical motor.

The car has done 101k, around 14k a year that has invovled trips between Sunderland and Barcelona 3 or 4 times a year by the previuos owner. If that aint enough to keep it clean nowt is, especially the way I'm going to use it.

then best use a low saps/low ash engine oil,i have seen that you can get a fuel addertive that is also supposed to help with dpf life.

Thanks Dray, for the reply,

I have had the fan come on a couple of times, while still cold, but was not in a position to wait for the regeneration, (work)
i have been told that a 20 mins blast down the motorway keeping the revs above 3k did a regeneration, but havnt tried it yet

steve

replace the dpf with a stright peice of pipe, leave the sensors in place before and after. the ecu will need resetting but it will obviosuly never block up again. The guy i use for mapping has done this to loads of taxi's in lancashire, only on PSA and VW diesels though, but i cant imagine the fiat being that different. Most descent remap companies should know what there doing.

Had my E320 merc done for much the same reason as you coozer, short commute, not enough long runs to clean itself. I used http://www.ecuflash.co.uk/. they removed the dpf filter, remapped the ecu so it forgets all about the dpf and gave a boost in power. 2 months later all is good, car is better on fuel and goes like stink. i took the car to sheffield for the dpf removing, then Andy from ecu flash came through and sorted the ecu, could not fault the service at all.

Please do not bite my head off for this comment, but could removing a PDF not mean an MOT failure after April this year or is it only CAT's?

Not be funny, but wouldn't a push bike or walking be better?

What I can't work out is if the pressure sensors that look to see if the DPF are left in and the DPF removed surely
the ecu will not want to switch to regen mode and everything will work as normal.
Also when a car goes into regen mode fuel is injected late and is not fully burnt and carrys on burning in manifold turbo and down to dpf to burn out carbon blocking it.
Think of it working a bit like anti lag but for diesels

In my opinion the car could overheat if the DPF is removed.
Exhaust gas recirculation is used to cool the engine, as diesels are now running on a very lean mixture and are getting marginal on overheating

Indirect injection diesel engines used to run at 750 degrees Centigrade approx. Direct injection engines now run at 900 degrees due to the loss of cooling effect in the inlet manifold.
Think when and why an EGR valve opens - It opens when cruising or on over run. It closes on acceleration as not as much Nox is produced due to the overfueling causing a drop in combustion chamber temperature.
Therefore removing the EGR will cause excess heat build up when cruising and on over run, on starting in the combustion chamber but obviously long term, throughout the engine.
The goal of the EGR is to reduce the combustion temperature and thus reduce NOx emmisions.

Re^^^^^

Sorry to the OP for the hijack

Please explain what "due to the loss of cooling effect in the inlet manifold" relates to?

Please keep in mind that I'm a simple guy.

EDIT: I was commenting on the post above BT's...must type faster. I hadn't thought of that BT lol

To quote from Autodiagnostics and publishing.com:

"The job of the EGR valve is precisely that, to reduce the combustion chamber temperature. By reintroducing a measured amount of exhaust gas into the intake manifold and back to the combustion chamber, the actual combustion is cooled down. The purpose of this reintroduction being that the exhaust gases, although very hot, actually contain no fuel or oxygen left. Therefore, the reintroduced exhaust gases would be neutral or inert with respect to the combustion process. Reintroduction of exhaust gases or EGR operation does not take effect during idle. Actual EGR operation takes place during high load condition, cruising, and light acceleration"

and to quote from how cars work:

"The main difference between Direct and Indirect Injection is the layout of the injection system, the Indirect Injection System actually has a small swirl chamber above the cylinder, where the fuel is injected"

On a direct injection system, the fuel is injected directly in to the combustion chamber.

Apologies for not being grammatically correct in my earlier post. I was just trying to get across the difference in combustion chamber temperature

To quote from another website (Not Wiki):

"Traditional (indirect) fuel injection systems pre-mix the gasoline and air in a chamber just outside the cylinder called the intake manifold. In a direct-injection system, the air and gasoline are not pre-mixed; air comes in via the intake manifold, while the gasoline is injected directly into the cylinder"

put the shovel down, please...

I'm on my way

Not that i know a diddly squat about diesels, but my DPF problems only started when i blanked the EGR off, as discussed in an earlier thread

Steve

Never mind the digging it is time for a reading from the good book and erect a headstone.

I looked into binning the DPF on my VAG 170Tdi lump a few years back. Lots of people doing it with no problems, as long as you map out the sensors to stop error codes appearing. Running 230bhp without the DPF and a map too!

Can anyone recommend a place where after I've hacked the insides out can remap my ecu please....

And, no more tizzies please.....

Who's coming to Stoneliegh for a BIG drinky????

The DPF is there for a very good reason. Soot particles are carcinogenic and are better trapped and burned correctly than being allowed directly into the atmosphere. I accept there are may 1,000's of diesels out there without them since they did not have them when new but surely we don't want to take the irresponsible attitude that pollution does not matter, lets move forward and reduce pollution.

We have 2 diesels in our household and both have a DPF fitted. They both regenerate when necessary without all this urban myth nonsense about thrashing them on the motorway. The ECU controls the regen, not the drivers right foot. The only time a run of 30 minutes above 2,500 rpm is necessary and specified by the manufacturer is when the malfunction light flashes.

The urban myth about cleaning them out is complete nonsense, the soot is bonded to the matrix and can only be burned off at temps above 600 C, steam is at 100 C (below normal exhaust temps) how is that going to work.

The fuel additive is Eolys and is used in mainly in certain diesels of Peugeot/Citroen origin where due to the DPF location the regen temp of 600 C cannot be reached by adjusting the injection timing. It cannot be simply added to the fuel since it is a dangerous chemical, it is kept in a separate tank and added in the correct amounts as you drive.

I had a 96 Golf TDi, the smoke/soot it kicked out when you floored it was embarrassing, don't want to go there again.

Anyone removing a DPF should fail their MOT just like you do if you remove a petrol Cat.

(Anyone removing a DPF should fail their MOT just like you do if you remove a petrol Cat)

This is the point I was trying to make (and failing badly)! It is an integral part of emmisions reduction and works with the EGR

Have a nice 1994 2 litre silvertop under the bench ready for the next project, no cat, emmissions again, yipeeeeeeee.

My Seven does not need a Cat, if it did it would have a working one. In 19 years the car has done less than 30,000 miles, not much in the way of emissions compared to a 12,000 a year diesel. It has always been properly tuned not only to ensure it will pass its MOT (visible smoke but some stations have insisted doing a full test at times) but also ensure its as economical as possible.

The 2 litre Blacktop does 32 mpg on a run, my old 4speed 1860 175 bhp x-flow 3.92 diff 185 60 13 tyres (4400 rpm at 70 mph) used to manage 16 mpg, don't want that again.

I find anyone commuting 1.1 miles by car, if they don't have to carry a large amount of tools, shockingly poor form!

I commute just under 4 miles & when it suits I go on the push bike which takes 20-30 mins but most of the time it's just not suitable.

Nice to see ya back Alan.

So, there I am sitting on the fence behind the barrier thinking about the reason the thing gave up on the motorway... car sitting silenty on the hard shoulder.

Nice AA man comes, plugs in and says "DPF blocked mate, where do you want to go?"

Energy Tuning mate thanks.

Towed up there and on arrival we get it going to find nothing coming out the exhaust as it struggles to idle and rev up to 1700rpm!

24 hours later I have a car that actually goes properly! Smoke test well under the MOT limit, no suprise really as my 16 year old 106D whacks it as well!

Darren at Energy Tuning is a fantastic guy and if you want yours doing he can retune your ECU via post.

Steve

States on the website 'From £299' but how much did it actually cost, if you don't mind me asking?

Phil

£350 including an oil and filter change. If you can remove the filter yourselve, mine was welded on - its £199 for tuning the ecu.
