Technical Fiat Ducatto Camper van Error PO401-61

[CazK]

I live on the Isle of Wight which is a small Island off the south coast of England.

I have a 2018 Fiat Ducatto 2.3DS 130CV E6 T.L Cabinato P.Lungo H1 17
it has 25000 miles
I bought it in 2020 with 18000 miles

First limp mode event August 9th 2021 Lincolnshire

Had checked at garage found on journey and fault code reset


Trip to Scotland and back, warning light no limp mode.

Took to local garage in Scotland still no idea of fault

Second limp October 2021 after a 300 mile drive.

Reset

Contacted 'Fiat expert' near Southampton and took there October 2021 however found no fault, reset the warning light and then drove 40 miles, on trip home. Limp mode

Following advice I changed the EGR valve, drove around Island on various test drives over the winter, no problem

Took on 300 mile trip April 2022 and 4 limp modes.
Again asked Fiat to help but vehicle too big, told to go to Adams Morey in local town but it was permanently closed.

Changed fuel filter.

Drove to Scotland, after 350 miles, limp mode. Called a Fiat garage in Scotland and arranged appointment in 10 days

Drove around Scotland with occasional limp modes
Took to Fiat Garage in Perth Scotland August 4th 2022 and received complicated diagnosis of a known fault

(see attached)

Drove home and one limp mode after 300 + miles
Spoke to Adams Morey and booked in to Southampton Branch.

Called Fiat Customer services but diagnosis had to be within 24 hours.

Took to Adams Morey on ferry, left there. after 2 days got diagnosis. Parts alone costing £3700
Called Fiat Customer services for financial help and am awaiting comment. Obviously I am outwith warranty.

It has taken a very long time to get this diagnosis partly because I am on an Island without a service station which will work with the commercial vehicle and compounded by test drive limitations. I do not know whether to leave the vehicle to be repaired in Southampton or if there is a more affordable route available to me, does anyone have any experience of this please?

Any advice gratefully received
Caroline

First question is it a Comformatic?
Daft question have you got a PC and a copy of Multiecuscan.
I reccomend getting a copy as soon as and reading this tutorial

then once you have some data we can help you. I

For MES multiecuscan i can only reccomend the PC version.
1 use a win10 laptop obdsx USB dongle and multiecuscan from Gendan with the yellow adaptor this is the easiest method

The alternative is to get a Bluetooth OBD2 dongle and multiecuscan direct from multiecuscan.net
(I also have Alfaobd Android version with a Samsung j6 phone a8 or tabA tablet and a bluetooth dongle.)
The advantage of BT is its wireless and laptop can be placed in a variety of places. The dissadvantace is buying a cheap one is frought with difficulties.
the price for a genuine one will be in the £20 plus region Beware of cheap ones about £10 they have been reported not to work

Hi @CazK, welcome to the P0401 club.please can I invite you to transfer to our ongoing post as detailed by @theoneandonly .
.
This post thread was originated by me.A number of us now correspond with each other privately as well.as being on here.
.
You need to read the full 18 pages and buy the MES package. We can help from this point
.
Alas any normal garage will have no experience of these twin EGR Ducatos and you will be asked to pay up £7-10 thousand pounds with no guarantees.
