I think you will find that yes they do, although I wait for the slap that says I am wrong

You aint wrong, but can I slap you anyway?
Hmmmm .. not so good then, from reading this:
http://www.theaa.com/motoring_advice/fuels-and-environment/diesel-particulate-filters.html
But if they have it seems at odd with the description at Italiaspeed, which seems to describe it as an option :
This compact, technologically sophisticated engine is also environment-friendly, because it meets Euro 4 emissions limits even without a particulate trap, which is available on request for certain markets.
The 1.3 Multijet 16v (whether 75 or 90 bhp) therefore represents a real leap forward in technological terms, and this translates into lower fuel consumption and emissions for the customer. ../snip/.. and keep its main defect (particulate emissions) to a minimum.

Apparently the new Fiat diesels are not too good to have if you use them on short journey's!

But that Italiaspeed article is from when the GP first arrived. They're now having to meet Euro5 standards which mean having a DPF is a necessity- all the 500 1.3's have them, as do all 159/Brera diesels.
DPF's aren't as bad as people make out, and the technology,design and reliabilty has improved massively. In fact, we've only ever had to replace one DPF (on a Doblo) and that was due to bad customer maintenance which knackered a camshaft and prevented the regeneration procedure from working effectively.
Even if you drive around town all day the system can carry out a regeneration with the vehicle stationary and at idle. The biggest problem is the Salespeople not explaining the system (and what occurs during regeneration) to customers.

True.
I've had my 1.3 for about 2 weeks now, done 140 miles around London, and i've averaged so far about 42mpg - i fully expect that to go up to about 50, for various reasons, but as with all fuel consumption stats, i'd be very careful when listening to the dealers and manufacturers generous statistics.
Flappingwings, 42mpg round london seems good to me, I would be pleased with that
My current car would struggle to get that on a traffic free motorway journey !
Seems like the fix is a good blast higher revs for a while, sounds like the kind of fix I can do

Dunno why I bother typing this stuff, no-one pays any attention. I know how T feels sometimes...
Oh, and Flappingwings- After 2 weeks the engine is still very tight. By the time you reach the first Service it will be much looser and return even more MPG.

Not as such, but it's a good idea to not use 100% throttle for the first 1000 miles- just gradually build-up the revs and loads over time and try not to labour it in a high gear.
And to be honest all diesels need a regular thrash, DPF or not- you can always tell those owners who potter about everywhere in 5th by the clouds of smog they leave at MOT time. Diesel fuel = better for the environment, my arse!

Yeah but what about the car tax danny, cheaper than a focus lol

... And Fiats don't come in a fancy paint colour that takes weeks to get right, PMSL
I think the usual reply is "Tango, Whisky, Alpha, Tango".

Alright Danny?
Just to confirm - should i drive like an old man for the first 900 miles?
This is my first brand new diesel engined car, so if there's any advice you have for getting good mpg and just treating the engine well, please let me know.
Cheers.

Every diesel should be thrashed regularly, at least once a week. When I say thrashed what I actually mean is hard acceleration through the gears, I normally recommend this to be done on a hot engine when joinng a main road. If the engine is new use 90% throttle rather than 100%, the reason you need to do this is to reduce glazing of the engine cylinder bores. If an engine is driven purely for economy the bore begins to glaze up (old mechanics may remember glaze busters when repairing engines), with a glazed bore compression is lost and oil consumption increases. By making the engine work hard regularly, the glaze does not get a chance to build up and is cleaned off the bore by increased friction of the pistons rings at higher revs and also the increased pressures within the cylinder. This hard acceleration also flushes deposits from the exhaust and turbo, and also makes sure the turbo vanes on variable geometry turbos move through their full travel and do not sieze in a single position or start to stick. One hard acceleration through the gears upto 70 mph once a week is all you need to do. The rest of the time you can drive for economy.
Out of curiousity, does anyone with a 1.3 75bhp know where the DPF is fitted (and in relation to the cat) as I have a series 2 GP, and cant seem to find it.
My manual seems to show it under the engine as the exaust routes back. However, this states only valid for the 90bhp model. I am not overly concerned if it has it or not, but it might be useful to know come service time.
