some vehicles i see can have milages as low as 3000 and need oil change. but normally they last until the next scheduled service. suppose it all depends on driving style/ journey length/speed.

driving a dpf diesel would be esp unsuitable for my country roads drive to work of 14 miles with speed limits of 30-50mph most of the way. thats the type of journey the 1.0 ecoboost is best at 

Is there an oil quality sensor on these Ian, or does the PCM just estimate it?

I know these wiring drawings are not 100% accurate, but generally they are pretty good. On neither DV6C nor DW10 for the Mk3 Focus is an oil quality sensor shown going into the ECM/PCM/ECU.

But interestingly, the DW10 (2L, as the OP has), has connections and a relay & fuse (F48) for a vapouriser. If a vapouriser is fitted, then the late injection system is unlikely to be used, so no worries about fuel in the oil. The vapouriser will heat up the DPF without this.

Also, if a vapouriser is fitted, the symptoms will be different. There is probably no need for the engine cooling fan to run at high speed, as all the extra heat goes direct to the DPF.

Tdci peter.  My car is a 62 plate 2.0 tdci 163 bhp job. So has my car got a vapouriser.is it a dvc6 or dw10 engine. Im getting so confused.   Thanks.

Thanks Peter.  

I know the Mondeo has a vaporiser but didn't know the 2.0 Focus did.  It would make sense though, with the DPF being further down the exhaust on the 2.0.

Your engine is the DW10, the 1.6 is a DV6.  The number usually denotes the engine size above 1 litre.  So 10 is 2.0, 6 is 1.6 etc.

yes , yours has vaporiser.

Ian has answered that one. I was not sure, sometimes the drawings show options that are not always fitted.

A Vapouriser is a relatively expensive bit of kit that heats, sprays & ignites hot fuel into the exhaust, just before the DPF. Deisel fuel will not ignite unless heated above its flash point of up to 96C. Petrol has a flash point as low as -43C by comparison, so will almost always ignite without any heating.

Ebay sells Ford vapourisers for about £145, which may explain why Ford tries to avoid fitting them.

It could explain why you have never felt any symptoms of a DPF regen, like the engine fan. The DPF is heated directly when needed, and the system should work fine with the engine idling normally. All it needs is a flow of gas with a good oxygen content through the DPF, and the exhaust gas from a diesel at idle, or light load, is mainly just air. So the regen can happen any time the engine is running. In fact, heavy load, which burns up much of the oxygen in the exhaust gas, will prevent the vapouriser from working.

The vapouriser system on the older Mondeo was rather unreliable. Ian might know if that has changed, or if there are any tests or checks to do. I seem to recall that it had a habit of blowing the vapouriser fuse, so that is worth checking.

Sorry this refer to previous file download. Its very gud info on dpf   looks like from ford..download file and have a read. See what you thi k

The pdf is quite a good, though rather optimistic (!) introduction to the DPF system used on the Mk2/2a Focus, to Euro 4 standards.

The bit where is says: "The  diesel engine will simply run like a charm while the filter is being “purged”. " is a fairly extreme bit of corporate blurb.

But it refers almost solely to the Eolys based DPF systems, and is out of date for the Euro 5 / Euro 6 Mk3 Focus engines.

Interesting reading (for me anyway) though!

Ford/PSA's much vaunted additive based system was so good that Ford dumped it pretty completely around 2011. In my view, not because it was inherently a bad idea, but because of penny pinching in not fitting a level sensor to the tank, making it a dealer only (for most practical purposes) refill, and other implementation details.

The vapouriser based system with a cDPF fitted to the 2L, Mk3 Focus is much better, at least as long as the vapouriser keeps working properly! Which again, is down to tiny design details. Hopefully they have got it right now.

Hi tdci peter. I notice the reference to a vapouriser. I have the 2.0 62 plate 2.0 tdci 163 .appears i probably have this vapouriser tho i dont know for sure. I looked on ebay and they are about 150 pou ds. What goes wro ng with them.assuming if car does not regenerate its poss cause is this item. Does it clog up with soot.  Can it be cleaned out or is it unservicable

Have a look in the engine bay fusebox. If it looks like the picture below, then F48 and R3 are for the vapouriser only, so if fitted there is almost certainly a vapouriser.

I do not think it clogs up easily, or wears out  in normal use. It should be reliable and long lasting. All I know is that some older ones on Mondeos were prone to a failure. I think part of it overheated, and then it blew its fuse.

@iantt knows more about it than me

If your DPF was not regenerating, then you would soon get a warning light or message about it, as the DP would be too high. So if you have no warnings, then I don't think you need to worry. The vapouriser type of regen is much less apparent to the driver, in most cases you will not know it has happened. Without a good diagnostic system, or some added wiring to put a light on or something when the vapouriser was running, I know of no way to detect it. Neither of those two methods are easy though!

I agree, it is a bit frustrating, if I had a dpf, I would want to know if it was working and being regenerated!

The vapouriser as Peter said was problematic on the Mondeo, and more so on transits . Done lots of them . Blown fuses. Blocked vapouriser pipes with soot. They can be unblocked assuming you can get the vapouriser out without damage to it. 

a few posts ago in this thread there was mention of in the regen cycle maybe the extra diesel in the engine would dilute the oil.

I have 2015 1.5tdci Fiesta (yes I know it's a Fiesta but this engine is more common in Focus). Mileage 37k.

Today i changed the oil. For a while the oil level looked a bit high on the dipstick (oil not topped up since last oil change 15k miles ago - Yes I know Ford say change each 12.5k). When I drained the oil out I thought there looked quite a lot there. So I measured how much was there and there was 5 litres.  There should be 3.9 litres max. So I can only assume there was a load of diesel in the oil, at least 20% of it would be diesel. Hate to think what this does to the quality of the oil in there and if it means engine wear will be accelerated . I know I should change the oil at 12.5k but assuming some diesel has been added multiple times over a period of time, there would still have been a fair bit of diesel in the oil even at 12.5k.  

It's a bit worrying. It's not come up with any warnings about oil quality but I don't think the Fiesta has any kind of sensors which would detect diluted oil. It's exactly the problem I was worried about when buying a diesel with dpf as someone else I know had continual problems of this nature with their Mazda 6 diesel. I just hoped that with mine being newer, the makers would have sorted all this kind of stuff out but maybe not.

As said before, it's not really avoidable due to the way these regen, there will always be some excess diesel.  For the price of an oil and filter change though, surely it's worth doing every 10k or so if you're intending to keep long term?  Ford aren't bothered as long as it lasts their warranty period, cars aren't designed for longevity any more.

I suppose I will just have to change the oil more often. Just been shopping at Asda and they had Castrol Magnetec on special offer at £23 (4 litres) . with the other half's staff discount that's £20.70 so thought I get it now so it's in my garage ready for the next change. (it is 5w30, I know ford say 0w30 should be used but I can't see the difference if not living in arctic conditions.)

Changing the oil is pretty straightforward. It's changing the filter that is more of a pain as access is not good. 

Is this issue just on tbe 1.5 diezel or all of them. Really dosnt sound gud at all

If you've not been changing your oil as per service intervals and not been using genuine Ford during your warranty period isetta, if you had anything go wrong you'd be out of luck when trying to claim.

This issue is the same for all diesels with a DPF I guess. I think you're panicking a little too much about it. I'm on 63,000 (got it at 13,500 2 years ago) on my 1.5TDCi and so far touch wood everything has been fine.

Only for DPF systems that use late injection to heat the DPF. A vapouriser can heat the DPF directly without any worries at all about fuel in the engine oil.
