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

[chumleywarner]

@chumleywarner in case things are misunderstood
i give my time for free, to help people.
your version is indeed 23
the lpegr cooler syndrome has been observed at your mileage.
get the pipework check out including the vacuum lines.
once you have a working multiecuscan setup i will guide you through some test . but now time for bed

Just checking you have received my DM with some recordings using the paprameters you suggested and if these have been recorded and presented correctly for you to see if there is anything obvious wrong that is causing my EML errors. I am due to take the van for the cambelt change next week and an MOT and will ask the garage to check the various turbo charger pipes as kindly suggested by @kangexpress including the vacuum lines just to rule out this being my only issue at this stage but I am interested to know if you can see statistics that are pointing to the LPEGR blocking for example? Just out of interest, if the DPF has cracked would the emissions test fail for the MOT? I have wiped my finger on the exhaust and it had a thin black layer but nothing that looked like a thickish powdery soot deposit. As you know from my DM I managed to do a forced static regen which completed but only reduced the partculate blocking percentage to just over 50% so not sure if this tells you something?

Hi , re DPF and MOT , I've taken into MOT test 2 times , with a cracked DPF and it passed no problem, last MOT emission read out was slightly higher than 1 st time ? It's going in again on Friday so hopefully I still have no issues!

Thanks for your thoughts on this @Serrow225 - incredible that a failed DPF can still pass an MOT but good to know.

 

[Fredastaire]

To ask a question again.
Someone said a long while back that they had removed their LP EGR for repair(?).
.
Do any of our members know if it can be achieved from the top without resorting to dropping off the suspension/ subframe.
.
I would still like to try a different cam inside the LP EGR.
.
So can it be done? If yes then how?

I think it helps to take van for a good run before test , get it hot .. use premium diesel,and miller's additive.. and how damaged the DPF is , mine is not that bad as pressure readings are within limits to not trigger a EML code .

Sorry I have not received a PM since I sent my templates. Please repeat.

Thanks , I asked the tuning company if they update software and change EGR and got answer back they do!

@Mike D Halliday
With your soot in exhaust and the set of codes P0401,P0236, P0238 you probably have a cracked DPF , but I would need data to prove this. The comfortmatic is more prone to this and will need software updates to the ECU to V32 and update to the Transmition Control Module.

 

[theoneandonly]

: is there anyway to get the code reset ecu reset manually without using a reader? NO(I'm beating myself blue for not bringing mine in the first place and here in Spain Ive been trying to find one but proven Extremely hard!) See bellow Is there anything I could diy to help me get back home eventually dealing with all these other problems that would be greatly appreciated! I did bring a toolbox with some tools and pretty diy handy.

aT least exhaust is clean as yet no P0401 so not all doom and gloom. If you have an android phone or tablet the simplest thing would be to buy a Vgate ICAR PRO bT4 OBD DONGLE AND DOWNLOAD Alfaobd the demo version free. you should then be able to check your software version and read any codes. the full version price is currently $50. Buy dongle from Amazon.es and deliver to one of their postboxes (easy im told but never done it. IF YOU GET SORTED bloody capitals with alfao obd in spain let me know and i will advise how to get some live data. I find Multiecuscan easier to use but have alfaobd capability in van at all times. If you happen to have a windows laptop to hand we can sort that as well.

Thanks , had not thought of the Amazon route and pickup points spent ~30 ao minutes checking it out but all have longer delivery times (will be home by then hopefully) does anyone know what type of physical shops that possibly stock these in either France or Spain? I have Torq Pro on my Android guess that's ok to read codes and reset maybe not get software versions , I'll go the multiecuscan route once home . Had hoped to not go down the route of having to diagnose the camper but it was not to be.

Hi everyone, Well I seem to be another one. 2019 Ducato Campervan (Pilote) 2.3 manual with the dreaded twin EGR. 24000 miles Serviced by myself - oil changes every 6k miles or so. Went into Limp mode a couple of times at the beginning of the year but I have a small Launch so managed to reset. Started looking into it and found this soap opera! I've managed to get the firmware upgraded from V28 to V32 from local Fiat Commercial. Now bought Multiscan. Regens look ok about every 500KM, down to 10% . No fault codes at the moment but have P0401-61 stored since firmware. Going to record a run in the next couple of days, Can I send them to someone?

If you post them here others may look but i will pm my email if you prefer.

Hi @athoirs - my ecu is still on v23 from the factory (2017 2.3 automatic) and I am considering getting it updated to v32 by my local Fiat dealer as there are many comments on here suggesting it will help with regens and also the auto gearbox which I have to say does seem very clunky at times. Could you advise what they charged you to do the software update (how long did they say it took?). Many thanks.

I specifically asked them to upgrade the firmware. This they did, also saying that "the EGR" might require replacement if the faults returned. I was £168 - and it took all day - but they are very busy - they said.

OK many thanks for this - lets see what my Fiat dealers say about the associated software update costs although I understand I also need my auto gearbox module updating at the same time....

Found what I was looking for yesterday! Funny thing is that I was in that shop Franchise first time I got it reset and they didn't know what I was talking about! Have reset code and pelted on the motorway and no new code gone are the ups and down windy roads and mostly motorway from here. Is Torq app for Android any good to collect data to see what might be up? Seem to have access to all the sensors and can log with it.

Just to get one of you thinking.
.
I've filled up my spare LP cooler with water. I used a rubber glove secured with rubber band to stopper the bottom end. Then holding horizontal as it would be installed, the Wife removed the glove and the excess water drained away thus leaving the pool of water in the lower zone of the tank.
.
Then drained out this 'pool of water' being circa 110 ml.
.
So if insitu cleaning were possible this is what would remain in the tank - to need removal - but how?
.
I'm also questioning if one could cut a rectangle of steel bulkhead away to reach the elbow that links the cooler to the actual LP EGR itself?
.
So.... I'm thinking....

Evapouration!
With mean cooler temp even above 80C it would all evapourate in time.

Forgive me if this has already been discussed or is just common knowledge but I have just been reading about the different types of engine oil and how these can effect the amount of ash deposits that end up in the exhaust system as some use more phosphorates and sulpher as these are added to reduce engine wear. I am aware of the different synthetics and that a fully synthetic oil obviously provides better lubrication, works better when the engine is cold etc. but I had no idea there was a level of SAPS tagged to an oil. I just spoke to our main Pilote dealer service depatment and asked them what oil they use at service and they said they use a mid SAPS fully synthetic (5/30) oil which being mid SAPS contains more of the phospherates and sulpher than a low SAPS oil does and this could be causing some of our issues if other service garages are also using mid SAPS oils. This is a good article that explains all about the SAPS rating - https://www.valvolineglobal.com/en-eur/low-saps-lubricants/ Had I known this then I would probably have specifically asked for them to use a low SAPS oil at service but at the time of the service a few months ago I was not getting any ecu erros nor read any of the forums and information that I know now. Does anyone else on here have any thoughts/comments on this or know what oil they have been using in their engines?

 

[chumleywarner]

BTW I am waiting on a call back from Motapart who supply the oils to the dealer who services our MH and getting some further advice on whether low SAPS is recommended for this particular engine - I will let you know what I find out shortly......
