Phew, that was close, 2 months ago I came very close to buying a diesel, not having ever heard of a DPF, luckily the garage advised me to get a petrol as I did a lot of short journeys.

Have something to contribute?

I think in future sales if the sales person does not tell you about the DPF and you learn later on that your driving i.e. is short journeys and the dpf causes massive problems you should be able to sue the @rses of these people. Its like selling a house and not telling the buyer the house is on top of an old mine shaft.

Hi there, this sounds like an issue i have with my 2012, 1.6 tdci. Most of my driving i around the City. When it does get out on the motorway at between 70 and 80 the engine seems to cut out. My friend says it feels like an automatic changing gear!! What do you think it could be?? Been back to fords twice now with less than 2000 miles on the clock. First time it had the software updated and the second time no fault was found! The problem is still there! Any ideas?

Not certain on Ford 06 but there are other sensors that a decent technican needs to check are working but it sounds like you will chase it if you are doing short journeys .I was a service Manager for and Audi dealer in West London a few years ago when the 06 07 first came out and the salesman didnt know what they were selling.As the customer crawled through centralLondon it clogged them up.

I got involved in helping customers basically reject the vehicle as it didnt suit their driving style and buy a pertol !!!
A bit later Audi brought out the comman Rail and this regens on idle as long as exhaust temp is up to 350-400 degrees I think it was and this made a huge difference.Yes the early DPFs need around 2200 revs for a certain time but this gets longer the more soot builds up .Sorry to say bit the bullet and change the car or your journey the problem will not go away otherwise regards Paul

actualy if people read the ford brochures it does state that diesels are not suitable for short journeys and low mileage and that if buying the diesel it requires to be driven down the motorway for 20mins once a month.it comes down to doing youre homework a lot of the salesmen dont have a clue.

Hi,

That's true, but driving down the motorway for 20 minutes once a month will not help.

On my motorway trips, in 6th gear, around 65MPH, the exhaust temp does not go high enough.

So the motorway trips need to be done in a lower gear (5th) to increase the revs and the temp of the exhaust.

Of course the brochure and sales people do not mention this.

As this thread in part it talking about right car for your driving style and requirements.

Here's my latest fuel consumption survey, 1.6 Petrol 99bhp:

Just done a round trip visiting friends up in the Northern Lakes part of Cumbria, 37 miles of A65 [which has few safe overtaking opportunities] so just going with the flow of the traffic. And I got 50mpg out of it just prior to joining the M6 for another 22 miles. Followed by 6 miles of A6 and 4 miles of county lanes. And the same route on the return journey. The dashboard readout read: Average Mph 43.0, Mpg 45.0, just goes to show it's that bit of the journey down the motorway that brings the overall mpg down.

And I was not hammering it, as the Tom Tom indicated 66/67 mph on average, though the speedo was indicating 69/70. This is because as most peeps know, the law states the speedo cannot under read the actual speed. Otherwise there would be law suits a plenty arguing that it was the car manufacturers liability, because you were caught speeding.

Anyway as I only do low annual mileage, the uncomplicated petrol variant is the right car for me. Ok I'd like the torque of a diesel, the lower fuel tax, the better mpg. But if you ain't doing the miles needed to make the savings needed to stump up for the problems you can encounter running a motor with a renewable DPF, then it ain't worth the hassle.

As the old saying goes................It's Horses For Courses

Hi All,

Just to share my DPF experience (or lack of!). I haved owned a 58 reg 1.6 TDCi DPF Focus for almost a year, and am on track for doing 10,000 miles. I do mainly short journeys, five miles each way to/from work, and go on the motorway at least once, often two or three times a month, for journeys of at least 30 mins, and often from Rochdale to Barnsley (around 50 miles/1 hour of motorway). I try to make sure I drive sensibly on short journeys; dropping down gear as soon as the engine feels laboured, not letting it drop below 1,500 RPM. Obviously on the motorway I'm in 5th doing 70+, so over 2,000 RPM.

I realise it's relatively early days yet, but I've not had a single problem with the DPF (or indeed the car itself). I'm sure many people would say that my driving needs don't warrant a diesel, but I love the low tax, power and torque that it offers, and with that in mind, I feel that 10k/year is justifiable. I also just prefer the way that diesels drive, and always have done really.

I read these DPF horror stories and hope that they never affect me! And yes, I do plan on getting rid of the car before the 75K replacement!

I'd be interested if anyone has any thoughts on this; have I just been lucky and am I likely to be caught out soon, or do my frequent motorway trips and DPF-friendly town driving really make all the difference?

Jon

youre just lucky so far after reading the ford brochure again it does state to drive on the motorway 1 gear below what you would normaly drive so 5 instead of 6 4 instead of 5.

i know of 5 people with dpf issues 1 of thems a focus and the problems started after 16 months 14k miles so expect to be bitten soon ignore the 75k some dpf have required replacement far earlier some later 35k miles ive heard on some.

its not just ford its all makes nissan have had major issues renault pugeot citroen bmw saab and manufacturers have slid down the reliability index because of this.

60 plate 1.6tdci here and I do more or less the same mileage as you , short journey to work on minor roads (12miles each way) and perhaps go on the motorways 1 or 2 times a month , still yet to encounter a problem with it.

If everyone one was just lucky with there DPF's having no problems I think you would see a lot more posts about problems on here?

just google dpf mate lol if you believe that there are many dpf posts and discussions on here the fact is it will happen its just a question of when even 5th gear did a segment about them on all cars and its an issue proving to be a headache for all manufacturers theres no set mileage or timescale but even ford tell you now if you do short trips a diesel with a dpf is not for you unless you take it on the motorway for 20minutes at a constant speed at 3k revs monthly.

ok i googled and it does seem a problem for some , I just hope I don't get any problem.

By the way if I was to take my car for a spin on a motorway to clear/start a regen process do I have to go at a certain speed In higher revs ?

high revs at any speed i believe its 3000rpm which is high in a diesel maybe some others have other ways of doing it im not sure but short trips without doing this will clog it up eventually

thanks , am I correct in thinking that doing the above or normal motorway driving will do a passive regeneration? and that the only time you get a active regeneration is when the dpf reaches a certain soot level in the dpf if the driver has only done shorter journeys with the dpf not being able to do the passive regen?

hope that makes sense :wacko:
