Technical strange consumption

[Kstorm]

Hi

I have recently purchased a fiat Qubo 2010 with 16.000 km on the engine,
and is normally using 5.0 L/100Km at speed at 100 km/t, but then suddenly it uses 10 L/100km, and in idle it's running on 1100 rpm instead of the normally 800 rpm, it's vibrates and smells hot, if i try to start it will use 25 L/100km all the way op to 60 Km/t then it falls (normally it uses up to 15 L/km under acceleration), then suddenly the vibration is gone and the fuel consumption is back to normal, and the smell is gone, no warnings light or computer readouts says anything.

I have a feeling that 1 of the diesel Nozzles is going crazy, and diesel is burned in the catalyst therefor it is getting hot and smells

In the Qubo is the 1.3 multi-jet diesel engine from the fiat punto

Could your dpf be clearing itself ? (it burns fuel to clear itself out)

dpf ?? is that the Diesel particle filter you are talking about, but maybe that could be it, but for how long is it doing that, and it is not every day or every trip that is does that, i normally drives 2 hours every day
(sorry for my bad english)

Hey, there is no problem with your english

Yes I meant the Diesel Particle filter.

Does your manual say anything about the DPF cycles ?

Many thanx Trev :worship:
i will try to call my Fiat Dealer tomorrow, and tell him about this maybe he will say "oh yes thats it, and then check the system to see if there is any errors on that DPF filter".

I will get back to you on how this turns out

Good luck Ken

Hopefully it is just the DPF.

Sounds like DPF, you should be glad its working correctly!

You were absolutely right Trev , it is just the DPF doing what it should.

I talk to a lead technical engineer from Fiat Denmark, and he said that it is a normal regeneration of the DPF, but in the 2010 model Fiat has changed the way it does it, so it also can do it at idle, because many do not get on the highway and therefore does not get cleaned the filter at high speed and high rpm, he was happy to talk to me when I had been very observant of how the Qubo'en behaves at idle when it has to regenerate the filter.

It get very very hot when regenerating about 600-800C

you all must have a merry Christmas and a Happy New Year

Hi Ken,

Glad that nothing is wrong

Assuming that Denmark is at present colder than us how can it get to 600-800C ? we are freezing our bums off here so dread to think how cold you guys are

Merry Christmas and Happy New Year

I didnt think dpf were fitted on qubo? Only as an optional extra? I was told my 2010 Qubo didnt have one.

Maybe it depends on whether it is Euro 4 or 5 compliant?

Euro 5 cars will have it to meet the pollution regs.

I have never heard of a DPF being an optional extra on any car, but I stand to be corrected on that.
