I eventually got a response to my queries.

Yes, I have v32 software.
I'm told there IS no software update for the gearbox ECU.

I suggest you read attached doccument there are/were software updates for the gearbox ecu. This is the last doccument from Fiat we have dealers now tend to be very tight lipped and dont give copies of important info to customers, ask for it

 

[Jiwawa]

there are/were software updates for the gearbox ecu.

@theoneandonly, is that the transmission control module?

Hello guys...

After a clogged agr cooler was detected here from my runs with MES, i took the chance and had the complete egr system deactivated.

The vehicle drove very very well for 1500 kilometers. Afterwards, a trip to Serbia was on the agenda. After 350 kilometers, emergency run and no power.
Laptop and MES connected, P0237-61 and P0238-61.. Boost pressure sensor A circuit low and Boost pressure sensor A circuit high. Clearing error and not being able to continue, error always came back immediately. I then drove another 600km to my destination with emergency run.

In Serbia I talked to a mechanic. He told me that when deactivating the EGR system, it usually takes 1000 kilometers and then the particulate filter is clogged. He also said that cleaning DPF is only successful in 3 out of 20 vehicles. The DPF was now really clogged again. The bottom was black after starting the Ducato, the tissue test also showed completely black tissue. The mechanic cleaned the DPF for me again. After 220 kilometers again P0237-61, P0238-61. Another 700 kilometers with emergency run back to Austria.

I will do a few MES test runs the next days and check if both egr valves are closed. After successful 1500 kilometers, I honestly trusted that the EGR valves were certainly 100% closed and everything was programmed correctly. I also ran through a tank of system cleaner for the injectors, as mine didn't show the best values after the last few MES runs. Let's see if it did any good.

I'm going to take a look at the MAP sensor, mass air flow sensor and throttle body and clean it.

It's exactly the same as what @ER worker described in his post #517, only it's the other way around for me, EGR off but DPF clogged up again and again.

Hi guys, I found short time to do a short run with MES. EGR system should be OFF, this run took place after a tank of system and injector cleaner, because my injectros was not the best in the latest MES runs. Unfortunately, I didn't have time to take a look at the throttle valve, map sensor and mass air flow sensor. Since my last post i didtn have error code P0237-61, P0238-61. But yesterday i got P0089-78 Pressure on injector support for the first time. DPF clogging jumped from 40% yesterday to over 70% today!?

Hi @Poachersmoon,

How did the 5 hour trip go? Still going strong with both EGR's cancelled?
Curious as I have everything ready to apply a LP-EGR cancel but, since other owners report errors after a LP/HP-EGR cancel, I have a little bit of doubt...
Also I am told together with the modified ECU map file, the wiring plug to the EGR valve(s) is to be disconnected. Is that the same on your 'cancel'?

cheers, Alex Schoots

Hi @Poachersmoon,

Are you still around / reading the updates? See above questions.

I am curious to your experience in a longer drive with the EGR's cancelled.
Holding back on cancelling the LP-EGR on my van - like to know your experience first.

cheers, Alex

 

[Fredastaire]

@aschoots I would still like to hear of somebody trying my thoughts of changing the LP EGR internal camplate to effectively stop the internal butterfly from closing (and thereby strangling the engine). This would leave the software untouched. I added a sketch of a replacement camplate a few pages back. The difficulty is working out how to get at the LP EGR, however one of our newer members has removed his from the top thus avoiding dropping the subframe.

 

[theoneandonly]

@Niko94 The egrs are off.
the injectors not good any better since cleaning?
turbo doing its bussieness.
Fuel pressure error. since i created template 4 i have added fuel pressure and temperature pids as being more usefull than last regen temp (this template is designed to capture when regen occurs). This may have more relevance to injectors and fuel filter performance. Regards your new problem check the fuel filter and pipe connections

This is my new general mainstream check template.

Now a strange question, if you have blocked off the EGRs function do you want to continually monitor that it is still blocked off or possibly use those pid positions to monitor something else?

Thank you very much for your help and for checking my csv.Files!

I installed a new Fuel filter before my 1000km trip. Filter was purchased directly from the Fiat dealer for €80!!! I have to check if I still have the packaging, because it said Made in China on it.

Injector cleaner probably didn't help. I would like to test the injectors from a professional workshop next week and then of course replace them.

Now a strange question, if you have blocked off the EGRs function do you want to continually monitor that it is still blocked off or possibly use those pid positions to monitor something else?

Probally to check if the EGRs are really continually 100% closed and OFF... because my stuttering problem.

This stuttering is always present in 5th gear at 2000-2200 rpm and 90-100kmh. Like if you let off the gas completely for a moment and then immediately step on the gas again. When he accelerates again he lets out a small cloud of smoke from the exhaust.

After replacing the injectors I will tackle the DPF. Either DPF OFF or buy a new one. Cleaning didn't do anything for me. Constant black residue on the floor and black dirty exhaust. If you let the car run for 5 minutes and then get back in and drive off, it starts to stutter and there is less power for the first 2 kilometers.

@theoneandonly, I ran MES with your template 4. Unfortunately, on the way out which includes a long hill it recorded a lot of nothing! For some reason I couldn't reload the template and had to reselect the various items but it has recorded on the way back. Unfortunately that doesn't work the engine as hard as there's a lot of downhill. Let me know if there's anything useful there. Thanks.

It's a 2017 Fiat Ducato 2.3l 130bhp with the updated software.

I forgot to wipe the exhaust (which was sooty but not clogged) before the run but I have now.

to save the template eg four you select what you want then Ctrl 4 together and that should save to four. press 1 and it should change to what is saved in one. then 4 and with a bit of luck you should have your saved 4 back.
i will have a look a data later.

Eventualy i realised i hadnt posted this so here's a number of graphs.

There is nothing obviously dodgey with the last 3.
The injector variances are outside the Fiat tolerance of +-2 as mine is.
The LPegr valve openings are as to be expected and in control.
the LPegr cooler temperatures are on the low side and would suggest a blocked cooler or not upto temperature, however, the temp sttarts at 60 and is upto 80 and controls, so not this issue.
The Turbo boost when in full throttle mode the actual boost does not closely follow the desired value with upto 200mbar difference. I think the turbo solenoid needs testing.

Turbo solenoid test

This discusses the option to test the (turbo solenoid)boost valve in MultiEcuScan.

Thanks for your observations @theoneandonly. I sincerely hope it's not the cooler that's blocked cos it was replaced!

The Turbo boost when in full throttle mode the actual boost does not closely follow the desired value with upto 200mbar difference.

Their work sheet stated "Turbo unit inspected, may be faulty due to related fault code 'low pressure'".... then "Tested all okay", which I assumed meant they'd passed the turbo. Maybe not?

I think the turbo solenoid needs testing.

I'll test that when I get the chance - thanks for the link.

The lpegr cooler result i was surprised at as i believed you had it changed. There is no black and white good bad line more like a big blury line. Lets keep a watching brief. A failing Turbo solenoid is not unknown, the most likely issue. (a respected person on this forum used to regard the turbo solenoid as a consumable and change every 28,000miles) It has a rubber diaphragm that can tear in use, analagous to a CV carb. The solenoid test can activate the turbo actuator rod which i am told can be seen from underneath the van. Should alleviate turbo fears.

Cooler removal- LP EGR
I've had mine changed at my local friendly garage and liased with them.
On a H ramp jack up body, remove front roadwheels. Undo bottom ball joints and track rod ends. Undo engine bottom locator strap. Undo steering rack subframe clamps. Undo the steering column inside the cab. Undo subframe, remove and set away on the floor. There are (I think) some heat shields on the steering rack to detach. The steering rack now dangles on its hydraulic hoses still fully pipes up.
Now you can reach the DPF for removal. The LP cooler is hidden behind the DPF.
I'm not aware of any of our series Ducatos needing a new LP EGR or it needing cleaning.
.
Do be aware that if multiecuscan shows the cooler to be blocked then that indicates the DPF has cracks.
.
Do be aware that a cracked DPF may have been caused / linked to wrecked/ faulty injectors.
.
I had my cooler changed 18 months back, im aware that my DPF is cracked so I'm unsure how long before the cooler re-blocks. Having a bi-annual cooler change is my choice to avoid the hefty cost of a replacement DPF.
.
If your garage says there is a problem with the HP EGR thats due to a software error which tells the mechanic that it's blocked. It's so misleading. Fiat must be earning Megabucks from selling new HP EGRs to replace perfectly good ones.
.
The miss leading bit is that when the LP cooler is blocked, the software asks the HP EGR to open up and compensate by letting more exhaust through, it's instruction to the HP is a crazy high stupid impossible air rate and because it cannot comply the software gives the 401 fault code which in turn tells you ' HP EGR blocked' when if course it isn't.

Hi, we are considering buying a dual egr van to convert rather than an adblue. Can I ask if you can give us a ballpark cost for this work so we can include it in our budget. I appreciate it will change depending on location etc.
Thanks.
Paul

Afternoon all, I've got similar issues so will be working through this thread for valuable help, thanks to everyone who has contributed.

We have a 2017 Ducato, manual, 2.3 multijet2 130bhp with 20,000 miles on the clock. We use it as a camper in summer months only. I had a P0401 code four or five years ago, I cleared it with a generic OBDII reader and it never came back, it's driven like a dream ever since. The van has been laid up for the winter (6 months) and I have given it a run today to bring it out of hibernation.

It felt sluggish, no turbo, drove it for 2 mins and came back home, coming up a slight hill it went into limp mode, engine light on. Plugged in generic reader, P0236 and P0236P codes, I did not attempt to clear them. Left it a while, started it again, no engine light, went for another short drive, same happened again, this time the reader gave P0236, P0236P and P0238, P0238P. All relating to turbo boost sensor circuit A.

The van has not been to a dealer since we bought it, mainly due to having only covered 10k miles in 6 years, but has been to a good local garage who changed the oil (proper spec) with an MOT and I have done the filters myself. So if there is a software update overdue it hasn't had it. We very rarely do short journeys in it, we tend to go away for a week at a time usually involving lots of motorways. Over the winter while I've been working on the inside of the van I have tried to start the van regularly although I did take the battery out completely for 2-3 months and trickle charged it in the garage.

I will go back and read this whole thread word for word now to try and ascertain the best way forward form here. Can anyone tell me if my engine is the dreaded dual EGR version please? And is it worth simply trying to clean / replace the boost sensor? Then take it to a main dealer for the software update?

Also, can anyone recommend a good Fiat Commercial / Iveco garage near me please in case I have to admit defeat? I'm in Somerton, near Yeovil in Somerset. The only place I know near us is FJ Chalke main Fiat agent in Wincanton, was hoping there might be a more reasonable independent specialist somewhere?

Was supposed to be going away in three weeks but that might be ambitious now, but will give it my best shot, at least the evenings are lighter now so I can tackle it after work. Would appreciate any tips that can help me on my way to a drivable van!

Also, in case relevant, like many others, have struggled to stop rain water getting into the engine.

Many thanks

Afternoon all, I've got similar issues so will be working through this thread for valuable help, thanks to everyone who has contributed.

We have a 2017 Ducato, manual, 2.3 multijet2 130bhp with 20,000 miles on the clock. We use it as a camper in summer months only. I had a P0401 code four or five years ago, I cleared it with a generic OBDII reader and it never came back, it's driven like a dream ever since. The van has been laid up for the winter (6 months) and I have given it a run today to bring it out of hibernation.

It felt sluggish, no turbo, drove it for 2 mins and came back home, coming up a slight hill it went into limp mode, engine light on. Plugged in generic reader, P0236 and P0236P codes, I did not attempt to clear them. Left it a while, started it again, no engine light, went for another short drive, same happened again, this time the reader gave P0236, P0236P and P0238, P0238P.

Okay, have removed throttle body and MAP sensor, throttle body nice and clean, little bit of oil inside the black housing it feeds into but not loads.

MAP sensor was pretty dirty so will replace.

But, if I search on the code that is on the sensor itself, Bosch 0281006028, I'm being told (on ebay) that it isn't compatible with my vehicle?? I get pointed in the direction of a different Bosch part number - 0281006076. So which do I go for?? Should I call a Fiat dealer and ask them to cross reference against my chassis number?

yes its a twin egr model, so now we know what we are dealing with.
In order to move forward you need to be able to use multiecuscan to read codes and more importantly live data a bit of reading first

What software/ hardware do i need to read OBD2 Codes

This a much bigger question than first appears. If we limit it to what is a cost effective DIY solution to "read my Fiat and simple maintenance issues eg change the oil in my euro 6 or add a new MAF sensor" then the answer for me reduces to...

once you can use MES you need to take a test run with my template 4. Get engine warm and at least 10 min run at 60mph if possible. 10 min run to a motorway and a blast up one junction and back is ideal. save the data as a csv and post it here or pm me. Also post the main page having connected to the engine ecu so we can see the software version. this important before you take it to a Fiat pro as they are unable to tell you what version you have it will only say it needs updating (whether that is the equipment or the dealership i don't know) FIat Pro are not normaly forthcoming with any info.
Next question can you take a piece of kitchen roll and wipe the exhaust pipe internally. Is it squeeky clean or sooty.
With the right info i can soon give guidance as to what problem is.

Hi, thank you for your help, so, exhaust pipe is clean as a whistle, nothing on the kitchen roll.

Happy to try the MES, but at the moment it wouldn't make it to the motorway! Will have to renew the MAP sensor and then do it. Is the MES software expensive?
