Noticed a little bit of stuttering around 1800rpm in my diesel last couple of days. Economy and (lack of) performance still normal though.

Any thoughts?

give it a good run (possible DPF related) then if no better dealer time.

Thanks - seemed ok today so will keep an eye. Being serviced soon(ish) anyway.

we had a bit of a scare at the start of a long journey to scotland in my bros Signum diesel. It began stuttering quite seriously at one point we pulled over to check but couildnt find anything. After a while it just went away and has never occured since. I put it down to fuel as he was terrible for buying the cheapest and running it well into empty.

Thanks - that's exactly what I do actually, at least the cheapest fuel in my area is Esso though.

Don't know if it is of relavence to that particular case but some diesel cars (ie VAG group) do introduce stuttering when the tank is low deliberately.

Its REALLY REALLY bad to run a diesel on empty, it damages something that I cant remember the name of in your engine lol
But ye its bad! Rather keep filling it up when you get to your last mark on the tank

most i've put in is 31 litres (showed totally empty for about 30 miles) - still 4 litres left!

Not really. The engine cuts out when it runs dry and the fuel pump (the bit you're probably thinking about) is usually driven by the engine so it stops too. If you ever run dry in a modern diesel just put fuel in and then turn the car to ignition and then back a few times so the pump is primed and then start. It's when you crank over a diesel with dry lines that you start damaging it.

Thanks for that, I was just about to tell Mrs Notts that in future she had to fill her car up before the light came on! I didn't know that because I'm not a petrol head see.

Thanks 306maxi
We learn something new everyday.

I was just relaying what i heard, and i accept your correction

I know but the Pug that is her car is a diesel!

I'll not be putting any more old chip fat in my 500, now I know of this potential problem (JOKE!!!)

Well its done us proud! Shame about the neurotic reverse parking sensors though!

the 1.6 diesel in the c4 picasso is just amazing, it doesn't even sound like a diesel when accelerating, so yes the french are particularly good at them

If you keep the revs up in a diesel (even an old one) they don't necessarily need to sound diesely.

no I mean from like 1500rpm, honestly it sounds like a petrol engine when under load. The 1st gear acceleration in it is petrol like as well - totally different league to the multijet, sadly

I have a 6 month old multijet that's done about 3k. I've noticed in the last month that at least once in any journey the engine will hesitate briefly, as if someone has cut the fuel supply; then it will run just fine.

Economy is normal, and if I push the car hard it's fine. I've also noticed it doesn't run very smoothly when the engine is cold, quite jerky one minute then unresponsive the next.

It has been to the dealer (D Salmon in Colchester) and they couldn't find any faults on the diagnostics machine. They did say the EGR valve might be sticking open, so they're taking it for a couple of days next week so they can see how it drives from cold.

Has anybody else had any similar problems with their multijet?

I've a friend with a 1.6 Citroen C4 Diesel and it is as clattery hell. The new Fiat 1.6 is much better.

Fiat's Multijets are renowned for their smoothness in fact, but YOU SHOULD NEVER RUN THEM INTO THE RED, or use cheap supermarket Diesel. Modern Diesels depend on extremely fine injector tolerances and are optimized for decent fuel..

The Multijet 2 Diesels arrive soon and the new injection technology will abolish the turbo lag of the 1.3 (much more low end torque) and improve both performance and economy. Win win.

Fiat invented the modern common rail Diesel and they say the Multijet 2 is the next big step forward. Then, later, when the engines adopt Multiar valve actuation they will do without EGR valves and PDFs as well. Win win win...
