Hi All,


My 09 Fiat 500 keeps going in to regen, like all the time! I have had the oil changed 3 times and a new dpf fitted but run it for ten mins and it goes straight to regen and smokes like hell, Any ideas? Local fiat garage is baffled ..


Or can anyone recommend a dpf delete and map out in Scotland?

Hi, and welcome to the forum.

Well I'm baffled too. If your local Fiat garage (I'm assuming you're talking about a Fiat dealership?) don't know what the issue is, and I'm assuming they've tested this all diagnostically and you've had a genuine Fiat Dpf fitted? then I'm stumped.

The only thing I can think of, is that on lots of new vehicles these days, if you have a replacement Dpf fitted, you have to have the ECU reprogrammed to know that a 'new dpf' has been fitted, and this can only be done diagnostically. I would have to do this on my Saab 9-3, but I have diagnostic equipment that I can 'marry' a new Dpf to the ECU if I have to.

Ahhhh...No not a fiat main dealer, And no he will not have coded the dpf to the ecu, The guys not very good tbh I shall take it to fiat main dealer or good independent and see what they say! Cheers!!

There you go then! Hopefully, that is all that is the problem, the Dpf just needs 'coding' to the ECU. It's something people forget, but to be honest, a garage not knowing this basic information, is ahh, disappointing....

Yeah, if you can, go to an independent or someone with the right kit because Fiat would undoubtedly charge a small fortune, though, they might surprise you and do the job for a standard charge, but don't expect to pay less than £100. I'm sure it can be done with Multieuscan, but someone who knows that kit would have to verify that.

Advisory!!!!

DO NOT DO THIS!

The Government sometime in the near future (yes, well all wait with bated breath!) are apparently going to introduce much more stringent emissions testing for diesels. This will include the use of equipment that will detect the absence of a DPF. One can argue the whys and wherefores of this all day, but at the end of the day, it is illegal to operate a vehicle on the public road that has had the DPF removed or deleted which was originally fitted with a DPF at the factory. Yes, plenty of places will gut and sew your Dpf back up again, they'll take your money and they'll have a damned good laugh at your expense because they too know the law. You see, it isn't illegal for them to remove the Dpf or gut it (that's their loophole covered), but they do know that if you use the car on the public road after they've taken your money, then you're breaking the law, period. They don't care, they've got your cash.

At the end of the day, Joe Public bought modern diesel cars fitted with Dpf's and many didn't have a clue that they were supposed to operate the vehicle to an extent that regeneration would take place under normal conditions on extended motorway runs etc. Lots of people bought a diesel car thinking that all would be well just running short trips around town and this just killed the Dpf. The guys selling the cars either didn't know about the Dpf 'issue' in the first place, or just didn't care, took the money and the commission and that was that.

I've run a diesel car since 2010 and I've had zero issues with the DPF because I live next to a motorway and I use that motorway nearly every day. My car has little concept of a trip to the local shop, we have a 1.2 petrol engine for that.

Cheers, thanks for the input! Will go to Harrisons Fiat in Edinburgh on Monday : )


I have a 2014 Golf Blue motion 1.6 and its superb! No smoke at all, the tail pipe is so clean you can put your finger in it and its super clean and never seems to regen,


Great car pity the government stazi are weirding out over Diesels...

To be honest, I don't have a problem with the Government's stance on this. After all, diesels do emit some nasty substances, allegedly....

The people I feel sorry for, are those folks who are going to second hand car dealers (or private sellers) and buying cheap diesels that should have Dpf's fitted, but probably, if they actually did some thorough checks prior to purchase, could find that the previous owner had the Dpf taken off or gutted. The second hand car dealer might not even know themselves, so they too could just as easily be duped. After all, if they buy a car from a private seller or from an auction and it has a valid MoT, they're not going to do much else to the car other than check it's legit/free from finance etc.

So Joe Bloggs goes to his local car trader (or private seller) and looks the seller in the eye and says, 'Is the Dpf still on this vehicle mate?' Seller looks him in the eye and says 'Dunno mate, how would I know that?' or just says, 'Course it has mate!' The fact is, virtually no one looking for a second hand diesel car post 2008, is going to ask that crucial question, they're just going to see a car, like the look of it, if the price is right, pay for it and drive away. Only later, sometime in the future, they have an MoT that detects' the absence of the Dpf, and suddenly, they're left with a pile of scrap because the cost of refitting a dpf is more than the car is worth. This isn't fantasy, it will happen, it's just a matter of 'when'.

Lots of cars that go through car auctions. Does anyone check if a diesel car is still fitted with a DPF and even if one 'appears' to still be there, if it's been gutted? Unless the Dpf is removed, no one will know. That car then ends up on a dealer forecourt or in private hands and no one is any the wiser. I'm surprised that some sort of written statement of fact concerning the presence and correct operation of a Dpf (for vehicles homulgated with such), isn't included during a diesel car sale, to protect both the trader and the buyer. As it stands, no one cares and no one is bothered because even the Government aren't doing anything.

Like your Golf H20MRV, my Saab tailpipes are super clean and I too can ooh err', shove my fingers up the pipe and it is clean, no soot whatsoever. Regular oil/filter changes, every 5000 miles, not a trace of nasty gunky thick black oil anywhere in or on my engine. It just annoys me when I'm stuck behind some nice diesel car chucking out piles of smoke on the motorway. You can often tell the ones that don't have a Dpf just by the amount of crap they're throwing out of the rear end.
