Technical "engine failure" warning & lack of power

Technical "engine failure" warning & lack of power

Alot of problems are caused by not resetting the oil degredation index, this happens when non-fiat garages are used, seen it many times. Not saying this is your problem kipper but there are very few taxi owners/companies that use dealer servicing.


So are you saying the computer still believes it is running on black, old oil & runs the car accordingly?
 
Hi have just joined site and glad to find i,m not the only one having probs with DPF, thought i was paranoid.

My 1.9 MJ started playing up March 09 should say it is a taxi 07 plate 108k miles now.

Sorry for the saga.

Thanks for the info kipper - keep us posted please - it seems we might all have some dpf issues at some stage:cry:

Totally agree with you about taxi owners but my local garage is a fiat dealer who I have a good relationship with.

Only ever seen oil change light come on once and that was week after first service. Not convinced warning light has anything to do with oil degredation more like a mileage setting.

This is my second Doblo but will be my last, had a jtd and it was a far superior vehicle in every respect.
 
Will say 1st service was done at Arnie's but did not use him again until engine failure light came on in March. They cited egr valve as faulty, they said it would be done under warranty, was a bit surprised as i was at 95k and was booked into my own dealer for service following week.

Decided to let them do work + service & mot.

Everything fine until few day's b4 next service and light came back on and only fault that shows on examiner is dpf clogged, the only thing that has not been changed is the cat.

Would appreciate any pointer's you can give.
 
Hi ,
just joined the forum and it would appear I've joined the Doblo " Engine Failure " club;) I bought an 08 plate Doblo 120 Dynamic from my local dealer about 5 months ago. I've had LOADS of Fiat's from them and they have been great. Car now has 18k on the clock. Problem started about 6 weeks ago; " engine failure " light on, low power. it was first diagnosed that there was a fault with the clutch sensor which meant that the car couldn't regenerate as it thought the clutch was engaged. On the second time the sensor was replaced . third time, last week, light on no power, back to dealer. there was no indication what was wrong except the car was trying to regenerate and wouldn't. Reset and fine till ten minutes ago so it's back to the dealer tomorrow. I have been advised re the " give it a good blast " now and again and I have changed my driving style to hold the car in gear longer between changes. i'll update tomorrow when they will rest it and it will be fine but for how long..
to be continued....................

I have been advised re the " give it a good blast " now and again and I have changed my driving style to hold the car in gear longer between changes.

remember that the "good blast" needs to last for about 10 minutes, so holding the revs before changing gear won't help.
You need to be on a dual carriageway at a steady 60 to 70 mph for 8 to 10 minutes.

This is quite a long time at that speed, you would travel about 11 or 12 miles in that time.
 
I have had the same issue with my 06 plate 40k Doblo.

First attempt by the garage was to change a brake sensor that they said was preventing regeneration and then to perform a forced regeneration (it apparently actually had to be done twice to clear dpf).

A month or so later it happened again. Car went in yesterday and this time they tracked down a software upgrade issued by Fiat that is apparently supposed to make the regeneration process less likely to fail.

Will let you know how I get on!

Thanks Rich,
My Doblo is at the dealers and they have asked to keep it a few days whilst they monitor whats happening with it. When I took it in they plugged it in and the blockage level was 106% ( strangely it can go up to 200% ) They took it for a run, plugged it in and it was then 17% so it had carried out a regeneration. They also told me that the last regeneration had been 800kms before which I worked out was when I was on the M6 on a long run. My problem seems to be that I travel about 6 miles to work and back and use the car in an urban environment whilst at work , so it may have to wait till the weekend when I am more likely to be doing a long journey and it obviously doesn't like to wait that long. If I knew that I had to do one longer journey every week and the car would take advantage of this and regenerate I could do this, but it still isn't ideal is it?
At this stage the dealer hasn't an answer but have said that they may end up calling in a Fiat tech from HQ. In the meantime I have a brand new 1.4 G Punto to drive around in.

I'll keep you posted.

Alfie.

Davy,

I feel we are in the same boat:(

Kipper 28 (& others) - how did you resolve this in the end? I'm at the stage you were at 2 months ago and would love to know how the story ended.

My story so far: 2006 Doblo 1.9 JTD 120. 100,000 miles. Went in to limp mode. Local garage & then Fiat dealer both tried to force regenerations but all attempts at forced regen failed. Both diagnosed the only cure was to replace the DPF.

I replaced the DPF with a unit from "Online Automotive" for £413 and a local garage fitted it for £115. 500 miles (of mainly high-speed motorway driving) later and the vehicle is back in limp mode, so I'm back to square one.

I have ordered a scanner from Ebay to reset the limp mode myself, so at least I can use the vehicle, but how do I solve it once and for all?

I now know from reading this forum (& in particular the post by NumanR on post 182180) that the fact that the DPF would not regenerate is a clue that the DPF is OK and that the problem lies elsewhere. So I've probably replaced the DPF for nothing.

Is there someone out there who really knows how to fix these DPF-related problems? Is there a mechanic somewhere who can do the job?
