I've got 69 plate gt line picanto. I've had ppf light on twice since I've had the car. Manual states run it at 50mph for 30 mins. I done that 1st time and it cleared the fault light. Yet to do it again as fault light only just come on, on way home from work

I have posted the info below several times and it has generally resulted in denials/derision from those who know better but increasingly people buying the wrong car are suffering dpf problems on this and many other forums

Some advice re DPF’s for those owners who do REGULAR SHORT TRIPS. I traded in my Chevrolet Captiva diesel for a Sportage petrol for reliability and DPF issues.
I do regular short runs and constantly encountered interrupted DPF regenerations, my neighbour with an identical car but doing longer daily runs did not. There is no dashboard warning light to tell you a regen has started.
The regen causes additional fuel to be dumped into the exhaust system to burn off the soot in the DPF the regen can take up to 20 mins to complete. If you interrupt a regen when you turn off the engine you may notice a burning smell, very hot engine and running on cooling fan.
If you continually interrupt regens then your DPF light will come on, if you continually ignore the light and do not drive for circa 20 miles at 2000 + rpm to burn off the soot then any or all of the following are likely –
Your DPF will block requiring a specialised clean – very expensive or a replacement DPF – frighteningly expensive.
The unused fuel will be dumped into the sump thus raising the level dangerously high and in extreme cases allowing the engine to run on to destruction on the oil/diesel mixture even after being turned off.
It’s unlikely that the warranty will cover these.
So what to do. Remember the DPF warning light is not telling you that a regen has started, it’s telling you you’ve interrupted so many that if you don’t drive till it goes out you’re on deep s**t
My Captiva was programmed to regen every 500 miles (Sportages are probably similarly programmed) so because of my regular short journeys and consequent interruptions I reset the trip meter at the start of each regen. At 500 miles I would keep an eye on the instant fuel readout which dropped into the teens and continue to drive up to 20 miles until mpg returned to normal. Sometimes very inconvenient but better than the alternative.
i have just collected my 2016 2.0 K2 sportage from local kia garage as the dpf light kept flashing at me and then the emmisins light came on and stayed on. I had this issue prior to my 4th service and mentioned it to the service centre and i told them I had driven along the devon expressway for more than 30 mins at over 2000 revs, he said you are doing everyting riight. It seem to settle down and we went away for a week towning the caravan. Going to the site the light never cams on. but the following day on a more than 20 min drive (minus caravan) it came on again. I then went to a kia dealer in Barnstaple and the first thing they asked me was what fule do you use, I relpied Tesco diesel, he said thats your problem you need to use one of the major oil companies fule as they put in the additives that help keep the DPF clean, supermarket fule does not have that. he told me to lock it in gear to drive with revs over 3000, done that twice, light still coming on. They have'nt solved it and told me thay are awaiting a response from kia's technical department as to what to do or replace. I suspect thay are requesting permission to fit a new DPF because of their cost, but not once have tha ey advised me to stop driving it and the MPG is fine. Mystery!!!

Is that really true though as there’s tons of debate on internet about supermarket fuels and most conclude that it’s a myth that they are bad for your car. I can’t imagine they are all putting a secret addictive in to just clear dpfs (although I could be wrong)

This thread makes interesting reading. I have unwittingly stopped the car and restarted to remove the “check exhaust system” warning. It transpires that this is not the correct thing to do as it apparently indicates that a Regen procedure is starting. My Optima is approaching 15000 miles and has indeed been undergoing short journies since March.

I am now giving it a treat with Shell V Power Plus fuel and wondering whether I should put in a bottle of Wynn’s DPF cleaner.

I’m driving most places in Sport mode and using semi auto option to keep the revs up at all times. Funnily enough does not seem to have adversely affected the mileage figures.

Will wait and see how we get on

update on my situation, local delaer ordered a replacement dpf under warranty. had 4th service on 5th aug. and reported dpf issue then. My MOT was due 3rd oct. and over a week before I reminded them that i needed the emmisions issue corrected before the MoT. Its now 16th and I have had to keep my car off the road, first I was told parts would be a week delivery, then it was 17th oct., then I was informed it was unlikely to be until end of december, I said 'you are joking' (no they were not). Since been in touch with customer services and they are now telling me 17th Nov!!!!. To top it all I discovered that having paid £40 to update sat nav, i noticed that junctions and roads it should have recognised were'nt, so checked with customer services on the version details and what they say my vehicle should have does'nt match apparantly update is issued in july each year and my update was done on 5th aug. Not impressed with Kia's service. Any body else had this sort of problem?

Well it's 28 days since my last post and I still have 100+ miles left before I need to refuel.

So that is over 600+ miles so far on Shell V power plus using sport mode for every journey. So far, there has been no recurrence of the flashing DPF light.

Car running like a dream (touches wood)!

Must admit I'm surprised that a 2016 car needs a new DPF! Have they done a full diagnostic test to identify how clogged it is? There are specialist services out there who do this sort of thing with the right diagnostic tools which are sufficiently sophisticated to identify and treat DPF problems without the need for a new part.

Just also a comment on sat nav update and I would definitely pull the dealer up on this and either request a refund or installation of the latest July update.

I used Shell V Power diesel on my last car and never once saw a Regen warning light in 60,000 miles. Now I have a Sportage I intend to do the same (or the Esso equivalent). I find I get slightly better consumption, but never had a warning light once.
