helloUnfortunately I don't know any French and my phone won't translate it. However, of note the photograph of part number shows it to be the same as my 2017 removed cooler. Please can one of our members provide a translation?
Hi BazSomething that for some unknown reason isn’t popular with the contributors here but worked for me (Fiat supplied all replacement parts worth £6k free of charge) is to complain to Fiat‘s CEO and keep complaining until you get a satisfactory response. Twitter may be a useful ally.
IMHO it just isn‘t good enough for Fiat to saddle consumers - who have paid a lot of money - with huge repair bills on almost new engines, due to their poor design and unsympathetic after-sales service.
That said, hats off to them in my case as I now have a 2-year parts & labour warranty - which hopefully I won‘t need if what they tell me is true and the new parts plus software update are the solution.
The service bulletin @Fredastaire refers to is 10.023.19 which I’m happy to make available.
Good luck…
HiHi, I started this entire thread. Are you certain that your Ducato is the same build version as ours? They were ex works Italy Sept 2016 thro Sept 2019 (reasonably certain on dates), they are Euro 6 but without adblue. These non adblue variants if going to a motorhome manufacturer could actually be road registered say a year later.
If yes yours is one of our spec have you actual known fault codes you can give us?
Hi and sorry to hear you‘re suffering from what looks like the same problem (same fault codes I had).Hi Baz
I find myself with this problem, MHome just out of warranty Amber warning light loss of power. MHome currently with Fiat approved service centre and awaiting news from them as to whether Fiat will cover cost of repair.
I have read enough of this thread to worryingly ascertain the cost of such repairs are frightening. I would want to follow your approach of challenge Fiat to cover these costs and any information you are able to provide would be appreciated.
I am not mechanically or technically minded so a lot of what is posted on here won't mean anything to me.
I will continue to read through these posts to try and understand more but I am obviously very worried from what I have read.
If you are able to talk to me about this I can send you my mobile number. Cheers Smudger55
Well smudger55 at least your'e in the right place now. you have the twin egr engine and the infamous P0401 problem.Hi
Although MHome registered 2019, i checked the VIN and its a 2018. I don't have adblue. The codes seem the same, refer attached. Work done so far has cleared the warning light but Fiat mechanic says diagnostics still find a code. Will find out later which one.
@Smudger55 what @theoneandonly says about Multiecuscan where I’m concerned isn’t quite correct, I only bought it after the first repair. You may well find it useful but, to be perfectly frank, it’s provided a huge amount of data but with no guidance on how to interpret and analyse it, I find it interesting but frustrating. One good thing is you can read and clear fault codes with it.Well smudger55 at least your'e in the right place now. you have the twin egr engine and the infamous P0401 problem.
There is a lot of experiance here concerning this (with and without Fiat involvement) as reading this thread will show.
I have not had the problem but analized data from a number of engines and problems.
first stop, read this.
now most important part of your 401 journey Buy Multiecuscan and an OBD2 dongle. Gendan is UK distributor, search here for alternatives.![]()
Ducato twin EGR Engine with P0401 Code (2016 to 2019)
This does not refer to earlier single EGR systems or to later AdBlu SCR engines. Note this is a guide and not definative. It is up to you to make decissions. It is the result of my investigations of data from many contributors and discussion with...www.fiatforum.com
You may ask why when i intend just handing it over to Fiat and getting a new mortgage (or getting Fiat to pay), Knowledge is King and key to this problem, even when Fiat fixed the problem BArry knew he had a problem by monitoring with MES (shorthand for Multiecuscan).

Tutorial to Measure specific Engine PIDs (Parameter ID) and Save data for analysis.
This was originally written to help one person with his Ducato totally new to MES to start saving data. it is not an exhaustive manual nor intended to be. Tutorial to Measure specific Engine PIDs (Parameter ID) and Save data for analysis. Open...www.fiatforum.com
I have updated suggested pids. When you have MES up and running post results (csv files) or PM me and we will advise from there.
Good luck with that, you never know…Having spoken with Fiat service workshop today, they arr trying to seek goodwill from Fiat. I don't hold much hope but will have an update early next week.
This potentially could ruin Xmas as we have booked a site near my mums for Xmas as a necessity. Cheers Smudger55
@Smudger55 I’m sure you’ll get plenty of advice from these guys, however one thing I’ve done is avoid any self-repair in case Fiat use that as a reason to refuse helping. You’ll see in the service bulletin that Fiat do, in fact, recommend replacing the HP EGR valve so it’s a conundrum - I’d be keen to hear what your Fiat workshop says.I've fallen in to the Fiat big hole in the road and climbed out of it myself. Current my van is running fine with no fault codes - however- I don't know if there is another pot hole awaiting me.
.
So with my hands on experience and knowledge gained with my van, this set of problems, and changing parts myself, I can only but strongly steer you into buying Multiecuscan to put to a laptop. I prefer the hard wire cable from Gendan rather than Bluetooth dongle, (but that choice is yours). At that point between the one and only and me we can tell you how to interrogate your van to work out whats right/ what's wrong. What is 99% certain is that your HP EGR will not be causing any problem, more certain is that it will be the LP EGR system at fault.
I've my own write up notes which should be of further help, please use the private message system and give me you email and I'll send a copy for you to peruse.
If you personally don't have the tech experience have you a friend who can help?
