Technical Ducato P0401 P0402 P0236 P0238 and limp mode its 2017 Euro 6, EGR changed, What do I check next

[Piotr129]

The ECM software for manual and comfortmatics had some different number eg v25 is known to be auto only others maybe man only the later v28 and v32 were used on both.

My 2018 Ducato has software version V25

@theoneandonly
I was going to get a copy of my setup next week for you, but having had to have an emergency gas engineer out, Ouch expensive, it will be a little delayed.
I can remember back in 2019 I had the safety recall from Fiat for the bulkhead brake pipes. Whilst in the dealership at the time (Luton) updated all the software free of charge (Engine and Comfotmatic)

I took the motorhome in to Fiat Professional this morning to begin the investigation tomorrow. They are to collect the info then involve a Fiat Technician to decide the way forward. Still no offer of financial help.

I ran Template 4 on the way up - only 7-8 miles but hopefully long enough to collect some info. I wiped out the exhaust before travelling, then again on arrival and showed that bit of paper towel to FP. They seemed surprised tho I have been telling them about this, and my fear of soot in the engine oil, for months.

T4 attached.

It seems as though I'm back again.

Following codes P0236 and P0238, a week ago the same codes appeared together with P0401 ahhhhhhhhhhhhhh

Following service/MOT today and investigation by Adam Morey, Portsmouth it appears it could be linked to EGR/DPF problems. Oh no!!!! For which I had an expensive repair. I posted back in 2022, I think.

They suggest however, I'll be better informed in the morning, that when I had the original repair, they might not have cleaned out the EGR cooler, which might be the cause of current problems.

You put your trust in these people and they let you down, excluding Simon.

just checked your invoice you gave me with part numbers it includes a Heat exchanger part number 5802131785 i believe to beLPEGR cooler. So they charged someone for it even if it was Fiat. How can I help?

Most as expected indicating LPEGR cooler issue. The HPEGR is fine working as expected.
You are due a regen pretty soon.
The injectors pass FIAT Limmis at idle


Well thats all I can say other than GOOD LUCK

Thanks @theoneandonly, is there anything in that (apart from blocked cooler indications) that would point to a cracked DPF?

The sooty exhaust
Have you still got the service news? its also in the downloads section
maybe this is the first thing they need to do they have already replaced the HPEGR

@Smudger55 How many miles have you done since your last repair?

Yes thanks, I do have the service news. They replaced the HPEGR on the last repair (Feb 24) not, so far, this time. They were about to check the injectors I believe. But in the service News that comes AFTER the DPF check.... I'm pretty sure they haven't done that.

I dont think so either , because of the surprise to see a sooty exhaust

It was october 2022 so just outside a two year warrenty Fiat should have given maybe within if @Smudger55 had allready taken it in for related eg turbo problems
