Hiya,

Which OBD reader and software do you use? Is it laptop based or android/apple or a specific reader?

Cheers David
Mine is a real cheapie.. There are many out there... See Technos thread for more info...

I have one like this. http://www.ebay.co.uk/itm/WiFi-ELM3...one-ipad-PC-/251377536747?hash=item3a8744ceeb
Works on wifi to my ipad / iphone.... with an app from the app store.. Was a free version but cost £10 for the premium version to allow code clearing,,
the Torque app that Techno uses I dont think they do for the ipad/phone..

Hi Tonka

Which app did you get from the app store please
It's called EOBD-FACILE.. There is a free version and that will get fault codes. You need to pay to remove fault codes. Think it was £10.99 for premium.. I am looking for other apps, Techno recommends that Torque but I dont think it's on app store.

Been reading up on "Novascan", seems to be able to start a forced re-generation of the DPF.. But £15 to buy and no free version to look at... :(

Motorhome 746 fiat ducato
Exp
Since 1990
Had same problem. 2013 746 roller team on fiat ducato base. Fault showed as PDF blocked and went into "slow" mode. Told was way I had driven it. Not happy, told them its a motorhome and definetly not done short journeys, generally drive above 2500 -3000 rpm for at least 20 mins on motorway and no regeneration light had ever come on. Only done 13000 miles. They had to conceed they were wrong. Found to be faulty sensor. Was told sensor is now modified and the wiring loom needed to be modified. Seems very similar to faults going back to 2009. Are fiat still putting on sensors they know are not up to the job? All this was done on our private warranty as we were 6 months out of fiat warranty. Does ask question, if been modified why not Fiat's responsibility? Was told unless it's safety related fiat are happy to put cost of repairs to the motorist. Really do miss my ford transit travel home with the brilliant 2 litre pinto engine. In 10 years of ownership only had a throttle cable snap. Which I replaced in 10 mins with the spare I carried !

Cheers... I think i will get one one order and give it a go...
My scanner is only a wifi type and nothing on the software for re-gen, so as you say a hard run may be in order.
Fingers crossed...
If its bad enough even a prolonged run at max revs wont cure it.
It has to then go into the dealers for a computer instigated re-gen with subsequent costs....if that also fails then a new DPF at great cost.

A couple of businesses that I visit on a regular basis have occasional problems with blocked DPFs on Citroen Relay and Peugeot Boxer vans that are used for local recovery work. They fix them in their workshops by taking them off the vehicles and soaking them in a bath of Coca-Cola overnight, then reverse jetting them with a power washer.

It doesn't help that these vehicles now have a gearchange indicator on the instrument panel, encouraging the driver to change up at fairly low revs and probably preventing regeneration cycles from being started if followed religiously.

Thought I'd pump this up rather than starting a new thread.
Having this issue on our 2012 EU5 Ducato with similar fault codes related to the DPF pressure sensor. Currently has 55210304 fitted. Have checked connection and reset the fault codes a number of times, it was ok for a couple of week (and several 1000 miles) but has now flagged again. As such think a sensor change is the next obvious step.
Has anyone here replaced 55210304 with 51908411? If so did you have to fit a new bracket? Where did you source the connector, assume this will require changing.

The outcome for my problem that is mentioned earlier in the thread..
I was clearing the fault but eventually it went to limp mode and almost left me stuck in France. Local garage changed the sensor like for like but not branded as Fiat and was half the price, then reset the ECU ... It's been fine for the past year...

I still have the later version of the DPF sensor that I bought by mistake. So if anyone needs one for £20 let me know.

Had an engine warning light come on for my Fiat Ducato.I contacted the Fiat Motorhome helpline and was told to have a diagnostic check done at an approved Fiat service dealer. I did this at the cost of£96.00 and was told that it was the DFP sensor or maybe the whole DPF system. The minimum cost would be £562.00 and possibly a lot more if it was not just the sensor. I was also advised that I should not drive the vehicle. When I pointed out that the handbook said that the vehicle could still be driven they insisted that we should not drive it. In other words we were a captive audience and they could effect a repair at some indeterminate cost!
I took the vehicle home and contacted Fiat motor homes help line and explained the situation. I felt that a vehicle that was only three and a half years old with only 14000 on the clock should not have these sort of problems.
The vehicle has been serviced by a Fiat dealer but is now of course out of warranty.
Fiat motorhome shaved requested the dealer to put in a goodwill request to effect a repair. So far they have not responded and we still await the outcome.
Not enamoured with either the dealership or at the moment Fiat Motorhome help as they have not got back to us when promised.
Meanwhile the vehicle cannot be used for its purpose as a Motorhome!

Buy your own OBD reader, lots of info on here about them.. From less that £10 on ebay and get apps for your phone / tablet..
My local garage sorted the issue for me.. New sensor, software etc for £150 ish...
If it's out of warranty I doubt you will get very far.. Go anywhere on the internet and type in EGR or DPF.. It's full of issues on lots of vehicles...

DPF are way more trouble than they are worth, it was a cheap way to comply with Euro5 emissions regulation,
When the DPF regenerate properly it will burn the soot but this will still clog up the DPF with ash, so at some point it will need replacing or cleaning,
But on the other hand if the regeneration isn't successful over time the extra fuel that is pumped into the engine will increase the oil level in the sump,
It's imperative that if your oil level appears to be increasing that the level is reduce before you have a catastrophe runaway with the engine feeding off the sump oil to destruction,
Solution! Remove and discard, fit a suitable canister in its place and refit the pressure sensors so the ECU is happy,
Oh man , ent heard that term for a long time , a runaway .

Sorry guy's , i know this will not be liked , and i'll probably get slatted for it . But the modern motor is full of sensor's , this is the main reason i wouldn't entertain any new vehicle , of any type , not just a motorhome . Now if that's what float's ya boat , then fine , i don't have a problem with that . I've looked at some modern van's , though they are nice , the modern layout's don't work for me , and anyway at 78 grand , i'm afraid i can find other way's to spend money . I don't need , the grief these engine's will produce , certainly not the expense , and now their mucking around with the road tax again . I'm gonna stick with a 98-03 , 2.8tdi , manual , even though they ent without their problem's , by a long chalk .
Right now , i've got an 05 sooty van (suzuki carry) , it's got less than 50 grand on the clock , yet it's had egr issue's . I've got hold of an obd2 reader , cheap one off ebay , and it's always in use , todate , resetting the management light , as it can't find a fault , yep duff sensor's , van's loaded with the thing's . It's cost's twice as much to tax as my old van (Rascal) , and has less room . Though mpg is around the same , some of the latest eurotech motor's , actually seem to give less .

Nope I agree , BUT having said that if I won the lottery I sure as hell would not hesitate to buy a brand new MH :)

lmao , yep i know exactly what ya mean .

To be honest , i dunno if my view's would change , or not , should i win the lottery . As i said in my earlier post the layout's don't work for me . I'd certainly have money to burn , as i'm not married , and don't have any kid's either , i don't need to worry about passing what's left , down . One way to get over the maintenance issue , would be to buy a couple of em , that way i could use one , while the other's in for repair , one thing for sure though , i'd have a bloody good time , working it out .
Unfortunately , i don't rate my chance's of winning the lottery that , good , so i don't think it's going to be much of a issue .

Of course , i could improved , it a little , if i actually did the thing !! .

Just to follow this up.

Only just got round to sorting this issue, the MH hasn't been far recently.

Ended up sourcing a direct replacement sensor from China > http://www.ebay.co.uk/itm/182329930500 which worked out approx £140 less than the fiat main dealer. Simple job to pull the old one and replace. Looking at the DPF delta pressure reading in multiecuscan the new sensor gives a plausible reading unlike the failed unit. Will keep an eye on the DPF over the next few outing to ensure it regenerates as expected.

Did intend to fit the new Bosch sensor from Tonka, however based on the extra bits required to fit, a throwaway comment on another forum about a new ECU software and lack of sensor spec sheets went with a direct replacement. If anyone would like to purchase the updated Bosch item at a reduced rate please drop me a PM.

As inconvenient as DPF, EGR and other emission control system can prove ultimately they are fitted for a reason.

Hi all
Sorry to revive this old thread. I've just bought a 2013 ducato based mh. After about 200 miles the check engine light came on and stayed on for our whole holiday. No loss of performance. The van has only done 10k miles since new so I don't believe there is any issue with the dpf. I have pulled the fault codes, they are p2454-29 and p1205-21. The first is the sensor signal and the second the pressure. This to me points squarely at the sensor being the issue. I cant get a clear image of it but am 99.9% sure it's 55210304 from the range of images i took.

@rutteger is that Chinese part still working? I guess i can try that or the bosch one!

Any other views on my issue or if I've misinterpreted the codes?

Hi,
The Chinese replacement sensor works mostly fine after 18 months. During the first few months the engine light came on occasionally, ended up just clearing the codes as a matter of course. Looking through multiecuscan there is a diagnostic routine relating to dpf sensor replacement - did not run this at the time. Touchwood no engine light related to dpf for a few months, just other faults...

Thanks. I ordered one and will give it a go. On a related note, the pipe clips on the sensor are foreign to me, do you know how they release?
