Engine management light on.

[Shemdog25]

Good evening all. Hope everybody well.
Right. So we’ve been travelling round Europe for 8 weeks and came back mid July. No issues whatsoever, but decided to get oil change and all new filters. Not used the van til last weekend when we had a few days in Mablethorpe. That’s when the engine management light came on ! With a ‘ check engine’ warning message. We had just arrived and was fine. Booked in and the light was on when I started it back up.
Got back to Sheffield no problems, with the light on and had a diagnostic check which came up with the code P2454-29. A couple of things came up.
Has anyone had problems like this on a fiat ducato 2.3 multijet 130.
Thanks all

Usual steps if you chuck the code into Gemini - I'd check the hoses aren't perished and the plug is OK first and hope it's not the sensor.

Sounds like it needs a dpf regen to get the pressures back to spec.

Had something similar with my 2012 Autotrail 2.3.

Gave that code (or similar) and i used to clear it with a cheap OBD reader but the light kept coming on over time,
Eventually it went into limp mode on route back from Spain ! I managed to get it home and local garage fitted a new sensor, did a Re-gen and all was fine.. Total cost at the time £130..
There are many thread on similar issues / codes and some horror stories of main dealer charging huge amounts to rectify..

In my research at the time i found they used 2 different sensors, so you first need to establish which one you have. Also they use them on so many vehicle.. You can buy one for a Fiat costing xxxx but then same OEM part number for a Lancia for half the price !

My first reaction would be some DPF cleaner in a quarter tank of fuel, then taking it a good run up a motorway keeping it in a lower gear and high revs.. So it's helping the regen...

does sound like the dpf i had the light come on but was erratic on one day off the next etc took it in the garage and the mech said “could be the valve could be the sensor just take it up the road and drive it like you stole it “ the missus piped up that’s how he always drives when he stopped laughing he said i’ll order a new sensor then , he did explain something about power outputs on different engines ie petrol engines curve diesel engines go angled and a diesel is more efficient at higher revs so driving slowly to conserve fuel is false economy on a deisel

We had a similar problem some 18 months ago, after the M/Home [2016 2.3 130 multijet] had been parked up for 2-3 months after a Winter Trip to Spain. The DPF Filter had absorbed shedloads of moisture whilst parked up [in coastal Fife], and mixed with the soot to make a soot pie that caused an 'outside expected parameters' message. We were advised by the garage to drive round for 1-2 hours whilst they waited for a new DPF to be delivered [75 miles burning diesel for the hell of it ...] at high revs, and this did clear the fault, but the garage said the fault would recur, and the £142 bill for diagnostics plus supply and for new DPF was good value!

The M/Home has been parked up in high humidity Fife again for over 5 weeks, so took it out yesterday for a 25 miles thrash up and down the A92 dual carriageway to remove any accumulating crud. Last trip was return from Drax in August so around 240 miles of 55-65mph driving for about 5 hours

A bottle of DPF cleaner ( toolstation / screwfix) is worth dropping in now again when you know you will do a long run

On preferably dry days, I like to take mine 30-50miles to somewhere nice, park up and have a cuppa and homemade sandwich before driving back, about once a fortnight or more.

Keeps the rust of things where it shouldn't be, including my driving, and give the van an airing, the mice and rain water less time to settle.

Last but not least, gives me a chance to enjoy the undiscovered changing countryside!

Sometimes, why not take your better half?

 

[the1andonly]

From my database, these 2 are fiat epr so depending on precise model
P2454-29 DIESEL PARTICULATE TRAP DELTA PRESSURE SENSOR OFFSET - SIGNAL SIGNAL INVALID
P2454-29 DIESEL PARTICULATE TRAP HOSE LINE MONITORING FOR COLD CONDITION - SIGNAL SIGNAL INVALID
The X250 had lowdown differential dpf pressure sensors that were prone to condensation in pipes and sensor. The x290 has much higher positioned sensor (on firewall) the second error would sugest a pipe problem to the DPF.
Using Multiecuscan would identify the problem simply.

Really stupid question as I’ve never used this. Do you put this in deisel tank ? On a full tank ??

Sort of... It does just tip into the fuel filler, I think the instructions do state how much fuel to have in the tank but to be honest i usually do it with 1/4 to half a tank..
You do need to keep the revs up to build up temperature. I usually get behind a truck for a couple of junctions on the motorway and run in a lower gear to maintain revs.

Cataclean is a good and recommended DPF cleaner as is Forté.
Leave about 70 mile of diesel in your tank, and then drive 40 to 50 miles for it to do it's work before filling or adding more diesel to your tank.

If you draw fuel down to as low as 20miles or 1/2 a galloon, with all the crud possible in the bottom of the tank, are you not liable to transfer the problem from one area to another?

I'm lucky, my 2007 X250 Ducato doesn't have DPF so I'm just curious and this might be another stupid question.

How do you, ' tip it in the fuel filter' do you mean remove it from the vehicle, or do you have another way?

FILLER... Not filter.... Have you been on that drink again..

You made me go back and check my spelling....

Oh yes, Sorry but you have to admit, it's been a long time since I made you do anything and I thought you needed the exercise!

PS, if it goes into the tank, wouldn't it be just as easy to fill up a tankful of super diesel a week or 100 miles sooner?
Just asking!

Total and absolute old wife's tale.
Any sediment in your fuel tank is mixed up into the fuel by the sloshing of fuel in the tank every time you drive, and that sediment is the drawn into the fuel filter reducing the amount of sedement in the fuel each time you drive.

 

[Googlebot]

Not trying to be rude or dismissive to others, but a cleaner or forced regeneration won’t help you with this.

The DPF sensor is terribly vulnerable to condensation which gets inside it and buggers it. I am on my 4th one now.

It probably needs a new DPF sensor and needs it coding in with multiecuscan, if the pipes aren’t cracked or broken that is.

Take a look at this thread.

Please don’t try a forced regeneration, it won’t work and will just waste fuel and possibly crack your very expensive DPF. If the sensor is broken, cleaner won’t work one bit either.

The the1andonly is spot on here.

If it’s the DPF sensor, the Amazon ones worked on mine and were £17. So far it has eaten 2 expensive ones and the original, so I had nothing to lose.

But my tank rarely gets low enough or braked hard enough for it to 'slosh' around much?

I'm just trying to be helpful to Funsters who's van sits still for months over winter.

It good that they can choose who's advice to follow.

Try put a glass of water on your dash and drive and you will see that even your leisurely driving style will slosh the water about.
You must also only drive on pothole-less and speed bump-less roads only as well.

A glass of water has no baffles to stop surge and is the wrong shape for a tank BUT many years ago, before potholes, I did have to do a similar experiment with a bowl of rotten eggs.
Thank goodness I succeeded!

Things may have changed now, but when I was a Commercial Heavy Diesel mechanic, the number of truck tanks I removed and had to be steamed out, was frequent.

But you do what you like, I like to keep my fuel filters clean and working efficiently.

Goodnight!

 

[the1andonly]

has the identity of the van been declared yet what year x250/ x290?
Googlebot is correct this has nothing to do with a blocked DPF YET. a dead differential dpf sensor will prevent Regen and then block dpf eventualy.

The first test would be to remove the electrical connector and check the 5V and OV have 5V and continous to earth.
2nd test remove the pipe from sensor and blow out pipes and sensor, we are looking for water.
If you read the guide you will see it is redicoulsly easy to diagnose with Multiecuscan.
If you need help PM me or theoneandonly on the Fiat forum. he knows almost as much as me.
Not got Multiecuscan then get it, or if near Northampton Ill test it, or look on Fiat forum there are a number of folk on the MES Register who will help
