General "Depollution" Engine warning message

[Stu DemonD]

My dealership never charged me to look at the problem - and fill the resevoir with more FAP fluid; after 3 or 4 long runs, the problem seems to have disappeared.

I think the light on ours only tended to come on when I was driving, and driving quite fast for long periods of time. It has just passed its MOT and emissions were fine as well.

 

[Lou]

Same here. It's the first time it's happened but it was when one was driving fast and for a long period. Do you know whether the fluid was topped up to the full 5 litres? Did we ever find out whether a Fiat bulletin was issued for the fluid to be topped up to the full 5 litres?

No, I gave up in the end - my dealership told me to speak to FIAT Uk, they couldn't do much more about it.

Originally, they said I would have to pay for the fluid, because it is treated as a consumable. And this fluid costs My argument was that they didn't put enough fluid in the car to begin with, so why is that my problem? In that case, they may as well not bother putting any oil in the engine as well, and let the whole lot go up in smoke.

realise this thread has been quite for some time but you guys may have already sorted you DPF problems.

Bought a 2003 2.2 JTD last weekend - 34000 miles.

light came on on the way home with the usual 'anti pollution system failure' message.

it went off the day later mid way through a drive.

it came back on yesterday on the way home from work - seems to lower the power output of the car and limit the revs.

Anyway - checked with the nearest fiat dealer and all the recall/service notes are upto date on the car.

He has seen this before and suggests either:

1. computer controlled regeneration at the dealership
or 2. run the car for 15 miles at approx 45-50mph and it will regenerate the particulate filter itself.

anyone heard of the 2nd approach and is this covered in the workshop manual?

will try the 15mile trip this afternoon anyhow.

cheers

I have heard of the first one but not the second one. When it happened to me for the first time I was on country lanes and almost definitely did 15 miles at the quoted speeds and it made no difference. Mine is to be looked at in two weeks time but since the light went out it has not returned though I have not done any fast motorway journeys. I have seen many references to Peugeot engines that appear to suffer from this problem. The fixes seem to be numerous though at the moment the favourite appears to be topping up with the special fluid which was not filled to the correct amount at initial delivery and on other internet sites a turbo replacement (this is not on Ulysses just other Peugeot engines with the same problem). I hope it is not the latter, though I am still under warranty, just.

did about 19 miles at a steady 45mph using cruise control and it had not effect.

probably take to to the dealer for a proper check later this week.
will get them to check the fluid level also.

cheers

 

[ccie1793]

went to the car this morning and no light.
did about 25 miles to/from work and still ok - maybe the 15 miles at 45mph works for the regeneration

Now you see that's the great thing about owning one of these. They make sure that your life is never boring, because you never know what is going to happen next.
Plus you get a whole new circle of friends to see on a regular basis at the Fiat service dept.

Well... I took my car in to the dealership in Corby in October for a service and to look at the damn Anti-Pollution message. It was diagnosed with needing an Overboost valve (something in the Turbo) this was not in stock so it needed another trip up to sort this out along with a new motor for one of the Electric doors as it was making crunching sounds. In between this period I noticed that I was able to make the light come on by flooring the accelerator (Overboost valve sound like the correct diagnosis?) I was also left with a screen on my RT3 (Monochrome screen) of Overspeed alert with options that do not respond to any buttons. This appears to have taken the place of my trip computer which has now completely disappeared from the menu (Pressing mode repeatedly). So, today it went up for the valve, plus motor etc. and for an MOT. It passed it's MOT before anything else had been done to the car so the Anti-Pollution Message seems a bit of a Red Herring as I would have thought that it would have failed if the message was accurate. Anyway one valve in place and a new door motor and on the way back down to London doing mostly 50 MPH because of an exceptional load in front and the light came on again. So obviously this Overboost Valve cannot be the answer. So it's back in touch tomorrow.

Anybody ever experience the trip computer disappearing? the garage did not seem to know how to get rid of this Overspeed alert though it must have been the examiner system that was responsible for putting it there in the first place.

only the obvious way . . . the button on the tip of the right hand stalk normally cycles between three flavours of the trip computer and the overspeed alert screen. Apologies for stating the obvious.

I thought that I had done this as well but I'll give it another go.

Thanks.

That was it! I was convinced I had tried it but I couldn't have. Now the fun and games begin as regards the Anti-Pollution message as I am getting the impression they are trying to get out of it by using the 'This is not really covered under the third year' At the moment I have a car that is not fit for purpose as I cannot take it on any A roads or Motorways without the power cutting. Still I have to take it up later on in the year as I am awaiting another part for a seat so they said that they would have another look at it. I still think that it is this special fluid (or lack of) that might be causing the problem. It would be nice if anybody knew the exact date that this directive was issued to dealers as regards topping it up to the full 5 litres.

Yesterday I took my car up to have a seat fixed and to have another look at the Anti-Pollution warning light error again. (car is practically unusable on A Roads and Motorways, Too many losses of power). This time they have changed an Overboost Relay/module in the turbo on top of the Overboost valve they changed last time. 34 miles later the error came on again with loss of power. I was going to ask them to top up the FAP fluid that has been discussed many times but after having read this thread by M6 Fan
https://www.fiatforum.com/ulysse/89343-diesel-filter-additive-level-too-low.html it looks as though one is warned by the system if the level is too low. The garage was asked to check the level but we were advised that it can't be checked from under the car you just keep filling it up until it overflows. The garage has been called and we now have to wait to see how we proceed.

My friend has a C8 and has just had to have this done at 70000. I have a Ulysse which is the same age but better spec and I have done 72000. I'm really really really hoping I don't get these problems! I'm worried as I use it as a Taxi and last thing I want is this happening on a busy weekend. Shall I get the filter and fluid changed now before the problems, power loss and error messages start?

These would be the best people carriers out there if it was not for what I have just read in the last 7 pages!!

Hi Novaman,

I don't know how old your car is but if you have not experienced this problem up to now you probably won't. Mine was just over two and a half years old and is a very low mileage car it had only done 15,000 miles when the fault occurred, it has only done 17,500 miles now mainly due to the fact I am not taking it on long journeys just in case. Judging by what M6 Fan has said you will be warned once the fluid is low, though if I'm not mistaken the filter should be changed at around 60,000 miles and the fluid topped up.

Mines on a 53 registration Ulysse Eleganza with the 2.0 diesel fitted.

I'll have a chat with the guys down at the dealership when I also take it down to get them to figure out my auto wipe and lights problem (see other thread).

Thanks for your advice though Lou.

Update on Anti-Pollution message. After over a week of the light having gone off and not coming on I took it up to the dealer who requested I leave the car with them for a couple of days. I did this on Wednesday and as of today it is still not resolved. They have changed another sensor on the turbo but are still getting the fault which now at least can be reproduced easily. The Examiner system is still stating that it is an overboost pressure problem but when they check the pressure it is within the parameters but the fault still comes up. They are in contact with Fiat HQ and will be holding on to the car.

Well.... after having a specialist have a look at it on Monday to no avail it appears that they are looking at a Turbo or ECU replacement. The worry now is on who pays for it. The argument I am getting is that the warranty will not cover it as even though it was reported during the 3rd year warranty there is no guarantee that the fault that it had then is that fault it has now. I don't quite understand this as the message on the dash has always been the same and the fault has never gone away.

We shall wait and see.

im having the same problems. The Engine Manage light on with the Anti pollution message on the main screen. Car is a 53 plate 2.2 Prest, had the fap fluid filled with a Litre yet lghts still on. Its only done 36000 miles. The dealer i take it to has billed me for wait for it £117 tried to tell me that he only had a litre in stock. Anyone got any updates or advice?

I forgot to post on this. I had the turbo replaced under warranty and now the problem appears to have finally gone away. In fact the car seems to drive better then it ever did (This may be down to me having forgotten how it drove in the first place). I also don't get the whine from the turbo from cold anymore. What error messages are coming up on the Examiner system? All mine were related to components within the turbo itself.
