Re: doblo dpf issue

citds,

The regeneration only happens when the on board computer "sees" a large preasure difference between the ends of the DPF filter indicating its blocked.

Fiatscan can reset the DPF regen counter, making the system think its got a new DPF filter installed and I think its also automatically reset when you reset the oil change (% oil degraded) option in Fiatscan.

Certainly there are stories of the DPF not regenerating if this is not reset.

I am not a tree huger by any means.. however I remember going to London, after the "clean air act" which forced people to use smokeless coal and so stopped the Thick smog's that killed lots of people every winter, however the amount of smoky buses and taxi's filled the air with almost invisible fog of particulates which caused instant thick black snot.

These fine particulates penetrate deeper into the lungs than even tobacco smoke and are highly cancerous.

Hence Particulate filters.

Shortly the MOT test WILL include a smoke test sensitive enough to detect the removal of the particulate filter.. when your vehicles WILL FAIL!

I am sure some MOT testing stations will already be installing the upgraded kit.. so its going to be pot luck which garage will fail a DPF removed car and which will pass it.

Re: doblo dpf issue

Hi fiat dealers carried out diagnostic test, found DPF blocked. To repair it would require, removal of the DPF, clean using chemicals,refit, change oil and filter reset fiatscan to carryout regen.
Cost 60.00 to carry out diagnostic test to trace fault plus 365.00 to repair it.
Was also informed fiatscan does re-set reg count at each oil change.

Re: doblo dpf issue

I have a late 2007 1.9 multijet and I don't think it has a dpf. Its the 105 version. I think the 1,3 has but not sure about the 120 version of the 1.9 multijet.

Re: doblo dpf issue

yeah thats my model 2007 1.9 multijet 120, fiat should supply a fiatscan with these cars cause unless you use main dealers you seem to be right up the creek. Every time you have a oil change you should re-set the oil change (oil degraded) option in fiatscan. BET NOT MANY PEOPLE NEW THAT.

Re: doblo dpf issue

Not many non-Fiat garages have the kit to reset the oil degraded counter..

The warning light will not come on until you have done some 30,000 kilometres.. and hopefully no one is daft enough to go that far without changing their oil at least 2 times!

I can totally recommend Fiatscan. Its an essential peice of kit for any Fiat car.

No Fiat dealer will supply it with a car .. how could they rip you off otherwise?

Only joking.. I am sure no Fiat dealer would think of ripping off a customer...

I recommend all Fiat owners get a copy of Fiatscan and then they can have their cars serviced anywhere and not get the oil degraded error.

Alternatively check to see if your garage of choice has the software.. I know Fiat Dealers have a much more sophisticated Genuine Fiat version..

But they charge 50 each time they reset the Oil degraded counter..

Fiatscan costs about 100 with a set of good leads.
Thanks gdove thanked for this post

To re-generate every 1200km the ECU instructs the engine to over-fuel to raise the temperature at high speed, this blows some of the crud out of the exhaust pipe, so who pays for the fuel?
May I ask where you are getting this information from?

Angry Re: doblo dpf issue

Had problems with my 120 ps 2007 Doblo going into limp mode due to a supposedly blocked DPF. We have a furnace where I work especially for cleaning these, so we baked it @ 650deg for 6 hours to burn out the soot. After re-fitting and clearing the fault code, it failed after 400 yds driving, so I changed the pressure transducer suspecting that to be at fault, (cow to get at!).
Nope, still going into limp mode.

Well, id had enough nonsense by now and have had the DPF software removed from my ECU for 270 by Devil Developments of Littlehampton. I made a stainless replacement pipe and replaced the wreched thing.

They are a pain in the backside, an example of automotive engineering at its worst. I'm sorry to say, for the automotive industry, its all about ticks in little boxes again, and the consumer has to pick up the tab when it all goes wrong.

Yes the car runs a lot better,
No it does not smoke,
Yes it will pass an MOT,
No it is not a legal requirement on an 07 plate vehicle,
Yes I am very pleased with the result, and refuse to pay an exorbitant price for a component that should not fail at 19000 miles.

They can stick their DPF's where the sun doesn't shine!!!!

Re: doblo dpf issue

I was refering to citds's information.

I know how diesels/DPF's work, I deal with them daily (however I research more into the health issues as a result these days)

Re: doblo dpf issue

Regarding DPF's and blocking.. had a chap in my Taxi who owns one of the new Jag XF (I think it is) which has a DPF.. he only dose about 4K miles a year, him being retired.

He had a warning light come on the dash and took it into the dealer.

They said his DPF was blocking up because he was driving too slow!

Their advice was to take it for a 20+ mile blast up the motorway once a month.

Since he has done this he has no problems any more!

I like a cheap fix

Regarding health issues.

My Father always stated that smoking did not by its self lead to Lung Cancer.. he sited research form Canada.. where there were no Lung Cancer deaths (even though a lot of the people in the country smoked) until Desiel Trains were put on their railways. (there were very few Desiel cars or trucks about in those days)

Apparently the incidence of Lung cancer needed a combined Smoking + Diesel and was proportional to the number of diesel vehicles / trains in Canada and of course the number of fags smoked.

My Father died aged 56 from heart problems caused by smoking.. which is a bit ironic!

But at least he did not get lung cancer!

Managed to get parts off internet at WipeX realy recommend these people got parts next day and seem much better than originals also very easy to fit cost 29 every Doblo driver should keep a set just in case

Re: doblo dpf issue

Common fault mine had done the same when I got it.

It was held together with a large bulldog clip!
which just about sums up the servicing mine has had.
Going in for new alternator today. -200

Not everyone gets the parts next day. I had a MASSIVE wait for mine last December/January. The company is run by one bloke and he was on holiday. Best thing to do is to look at his listings on eBay as he puts a notice up when he goes away. I saw that after ordering directly from the Wipex website!

I've got the engine failure message again. It's running fine as before, just got the damn message! Taking it to a garage on Monday, hope it's just a case of another forced regen!
