We have a fiat 2.3 euro 6 based motorhome which has covered 7000 miles. Upon returning home yesterday after a 100 mile run I noticed the cooling system fans were on when I was parking the motorhome. All temperatures were normal but the engine appeared to be hotter than usual. Also there was a slight smell of heat around the exhaust area. Is this normal. This has happened a couple of times over the past year. Is this caused by the DPF filter regenerating normally. As I under stand it on a normal regeneration there is no indication it is being done. There were no warning lights on the dash so I assume it was not a forced one. Would be grateful for any comment.
Fiat 2.3 Euro 6 DPF Regeneration.
- Thread starter ramsthom
- Start date
We have a 2018 2.3 180 fiat engine in ours and the fans do run very regularly can’t say whether there is a DPF light on it as never seen one.
On our Fiat Panda 4x4 diesel a light comes on when it’s regenerating.

This is out of our Fiat handbook there is a warning light
DPF (PARTICULATE FILTER) CLEANING UNDERWAY (for versions/markets, where provided) The warning light switches on when the ignition key is turned to MAR, but it should switch off after a few seconds. The warning light switches on constantly to inform the driver that the DPF system needs to eliminate the trapped pollutants (particulate) through the regeneration process. A specific message will appear on the display when the warning light comes on (for versions/markets, where provided).

I don't think you would notice regeneration whilst driving but if it is still doing it when idling you may notice a hot smell and if you put your hand near the end of the exhaust the gasses coming out will be considerably hotter than normal. That's what I have noticed anyway and when the ecu was downloaded at service it said it had regenerated 16 times over the past year but only noticed it a couple of times.
It also says that the warning light does not come on for all regenerations only when it is being driven in a manner that does not meet the regeneration process. I assume it would then do a forced regeneration.
What I really wanted to know is there a noticeable increase in engine/ exhaust temp when a normal regen is taking place.

I think yes the engine will become hotter as regeneration occurs, I tow a trailer with our car on so the engine revs are probably higher most of the time and it’s enough to not have forced regeneration, hence never had warning light on.
They do say drive in lower gear at higher revs for a short period to burn off particulates.

Yes, regenerations can occur in several ways. Firstly, you may be driving at sufficient speed and in conditions where the regeneration takes place without your knowledge or any intervention on the part of the vehicle. Sometimes, the vehicle may need to raise the temperature of the exhaust gases to carry out a regeneration. It does that in part by injecting additional fuel out of cycle (post injection) to raise the combustion temperature which is why you may experience an increase in the idle speed, activation of the cooling fans, an increase in fumes and a hotter than normal exhaust.
These regenerations are normal and occur without any notification to the driver.
Rarely, if several attempts at normal regenerations have failed, a warning message will appear on the dash to notify the driver that a regeneration is in progress. This is meant to let you know that you need to keep the vehicle running, preferably at around 2000 rpm or more, until the process has completed.

On my car it switches the heated wing mirrors on when doing a regen. So what I have done is conected a small led light in the wing mirror at my side when it does a regen the led lights up.

How often does regeneration take on average? I hace just been into my MultiECUScan software and it says on average it has regenerated every 221km. Average time 680 seconds. Last one was 70km ago. I have been doing long journeys recently across France, spain, portugal. 34000 miles in 4 years mostly travelling abroad so not a lot of town driving.
Is 221km normal?

Our 2.3 was exactly the same. The fans roared like a jet engine when the regen was taking place. Normally it happens at faster speeds so I couldn’t really hear them but if I had to slow down or stop it was very obvious. I think it is best to avoid turning off the engine half way through a regen but sometimes it is unavoidable. Ours had a habit of doing it at the most inconvenient times like starting one a mile from home.

I have no idea when a regen is taking place so not switching off the engine when one is taking place is not really possible.
If it happens on the motorway for example you won’t know but on our 2.3 it was very obvious at lower speeds when it was happening due to the roar of the cooling fans. We have a 2.2 now and I haven’t noticed any regens yet but it must have completed a few by now.

Yes goes up to around 6 or 700ºc
probably as around 500km is the absolute maximum & it will do a regen then if one hasn't been done

Normal.
Worrying the first time it happens but its normal - as exhaust/dpf is hotter the extra fans at full pelt just cool it.
140miles . is it getting more frequent? 200-500miles totaly normal mine sits at 250+-20. once went upto580m
Have you got a reference for that distance is it specifically for ducatos or a general DPF.

I only have the average from my multiecuscan software. I've never noticed when a regen is actually happening. The software tells me it is 221 km on average - that's just 134 miles - on average.
from Multiecuscan you can get the total mileage and total number of regens this will give the average regen distance to compare with the recent distance.
MES also gives the distance to last regen, so if anal enough you can monitor said regen distance.

This is where I am getting my info from.
So average is 221km. I have 70km since the last regen but unless I plug it in after every journey if another kicks in I will lose that info.
It's a pity it doesn't keep a list of km's between each regen.

I am only going off of O'Reillys dpf cleaning channel where the majority appear to have a limit of 500kms but regen far earlier

Hmm....just let Google AI educate me about DPF Regen. It appears there are 2 types of regen. Passive - natural regen when doing long high speed runs. And Active (ECU enforced regen)
Question - Will MultiECUscan record just active ones - or maybe passive to? That might explain why I have so many?

only talking about a twin egr Ducato
mine never passively gets to 550C so doubt its a major factor in Ducato regens
so all are either regens from flow resistance number of regens from flow resistance flow resistance >=100% (This is the number of consecutive regenerations activated from flow resistance.
or forced regens (ive never done a forced regen)
total number of regens= regenerations activated from all methods.
from MES Fuel quantity of indicated injection.
In the first generation of Multijet engines the main injection is divided into FIVE smaller injections (pilot, pre, main, after, post) to ensure complete efficient steady combustion within the cycle. The five injections are in the following order:
1. PILOT injection (for noise reduction)
2. PRE injection (for further noise reduction)
3. MAIN injection
4. AFTER injection (for soot/pollution reduction)
5. POST injection (for DPF regeneration) I use this as an indicator of when regen occurs
Yes i try to record every sensible trip.
