Technical HELP!! Massive clouds of white smoke (mostly) on Regen.

[KSch]

Thank you for the response.

Unfortunately, I don’t have any expertise in car repairs, which is why I took my Ducato to a Fiat workshop. They believed the issue was due to a faulty DPF, so it was replaced. As mentioned, that unfortunately didn’t help...

I have now found another mechanic to take a look at it. I hope you will share what the problem is when you’ve identified it.

Attached is a video of smoke from my car.

I will, just want to get to the bottom of it!!

Good luck with yours.

@Dizzydalek Does the attached pic help you? Let me know if your vehicle has the identical fitting/connectors.

Have you got the csv file associated with the pdf graph exhaust sensors.

The graphs are attached a bit earlier in this saga. Don’t have the CSV I don’t think.

The csv files are automaticaly saved with the general format FESExp_2410141258_Fiat Ducato (type 290) 2_3 Multijet_File4.csv the date being 241014 typically held in a csv folder of the Multiecuscan directory (actual location held in F9 settings.

I run MES in a VM so nothing is saved unless I export it before shutting down the mac. The CSV shows the regen proceeding and the temperature of the DPF increasing until it hits around 900 degrees at which point the temperature sensor throws the "short circuit" alarm and the regen stops.

Original thoughts were it's a faulty sensor and the DPF wasn't getting hot enough. Wasn't that though (that would have been far too cheap!!) so the DPF has been professionally tested and was officially buggered. Need to find the reason for the soot before I replace it or the risk is the same thing will happen again.

Back in on Friday for soot investigations.. I'll update this thread once I know more, may be useful to future archaeologists.

Hiya,

Just watched this video on my laptop.. that's exactly what mine was doing. I now know more about DPFs than I ever wanted to

Do you ever get a fault on the dash with this?

Did whoever swapped the DPF notice excessive soot in the manifold / down pipe?

How long does the smoking last?

 

[Dizzydalek]

Hiya,

Depends. Sometimes it made it all the way through a regen (so 5 minutes-ish) and sometimes the regen stopped short of completion. If it did this soon after starting it would retry almost immediately.

I ran MES while driving trying to gather info and this is definitely on regeneration.

Any ideas? Exhausted my own knowledge and had the finest professionals scratching their heads so fir to say I'm stuck.

I feel some empathy as I have a Panda that does something very similar, but never for as long as that (mine's for 6-800 metres or so) - and very oddly mine always (well, almost always!) does it in the same place on a regular journey from a cold start - and it doesn't ever do it during the warmer summer months. Not got to the bottom of mine.

Any relationship with the throttle on yours - does lifting off for a moment clear it?

It's a bugger!!

If you back off there is less "smoke" but it's just because you're pushing it less hard. Was funny when it did it and I booted it to try and get it over with.. Looked like a destroyer laying a smoke screen!

I'm more in the 007 escape mode, I like to feel! Still drives perfectly through it, no faltering or anything - it's more embarrassing than anything else.

I can control it by backing off too.

@Dizzydalek

Is your cat and dpf in one part?
Or do you have two separate parts for cat and dpf?

This almost the holy grail for apple nuts. So many people have failed. Have you got any details on what VMware how etc. USB handling a game ive been told. PS i'm not an apple man either use Linux mostly but stuck with windows box for a few applications inc MES.

It's one part, the precat and DPF in one big, expensive can. Confused me at first as the temperature sensor reports as being at the input to the DPF and I didn't realise that was the one in the middle

I tried for ages with USB and eventually gave up. Surprisingly it was a cheap WiFi dongle from Argos that worked.

Don't think I could set it up again if my life depended on it. Lots of trial and error

So now have the sensors connected to the loom correctly

They were connected correctly, it just meant that my first fault fix was to swap the wrong sensor )

Sometimes it gets through the regeneration, takes about 5 minutes with a lot of smoke. Other drivers think there is a fire in the car and honk their horn, flash their lights and wave their arms out of the window....

Other times it doesn't get through, then it starts regenerating again. But then there may also be error messages in the dashboard. It reports the following error:
- Hill keeps unavailable breeding
- ESC unavailable

Those who changed the DPF did not talk about there being a lot of soot or anything else abnormal..

As written earlier, I need a new mechanic to look at it. If he finds out something, I will of course write it in here

Looks similar to mine, it occasionally does the “hill holder” and “esc” thing. Mine is back in on Friday so I’ll keep you posted.

A new mechanic has looked at my Ducato, and he suspects that the cause of the heavy smoke is an aftermarket DPF. Do you know if your DPF is original or aftermarket?

Is there any news about your Ducato?
