Hi Newbie. Since I posted the above (yours), further research showed that the options were to replace the DPF (faulty and causing the oil to fill with diesel), get it cleaned chemically, or remove the filter material in the DPF and put it back on. I plumped for the later with a local specialist garage. They re-programmed the ECU so that it thinks no DPF fitted also. Fantastic - no problems since, fuel consumption back to normal, accelerates quicker, engine is quieter - just a complete success!

And no more DPF related problems - hurrah!

Hi Flashblade, been following this thread with interest and pleased you've found a solution.

 

Just wondered what effect removing the dpf will have on emissions at the MOT?

Hi Flashblade, been following this thread with interest and pleased you've found a solution.

 

Just wondered what effect removing the dpf will have on emissions at the MOT?

The DPF gathers the pariculates that are emitted from the engine and either burns more fuel to burn this off or dumps (some of) the particulates all at once when accelerating hard (often in built up areas etc, near schools etc)

 

With the DPF removed, the car spreads the particulates around more evenly, and burns less fuel because DPF regen is no longer required, and the car has a better MPG, so overall may have less impact on the enviroment

 

The overall enviromental impact of the car during its lifetime must be looked at including the energy/ materials used in manufacturing the DPF, CAT & EGR, the extra weight of these items, the (negative) effect on MPG, and the energy/ immisions used to produce all the extra fuel etc  

 

At the momment a DPF is not required for a UK MOT test, only the particulates are measured, as above, removing the DPF may actually help the MOT test, especially if the DPF is old, contaminated or faulty

 

Same goes for catalytic converters, and EGR systems - (not nessesary for the current UK MOT test as only the particulates are measured) - the EML (engine management light) must not come on after the engine is started (this was an "advisory" but will/ has become a "compulsory" in the test)

 

This was originally going to be brought in in Jan 2012, but was delayed - i don't know the exact timescale or what is/ isnt applicable and what is an advisory or compulsory      

 

In the future the DPF may be required, but as long as it looks like one is fitted there is no way the tester can tell if it is a functioning DPF or it has been "hollowed out"/ is empty

Thanks for that, very useful information!

 

I have avoided DPF diesels and run a 2.0 tdci Mondeo on a 54 plate which is prooving to be very reliable (Ooops!)

As the thread header suggests, there is concern that Diesel Particulate Filter fitted models have a problem that the regeneration process could be contaminating the engine oil. So it is either complete TOSH you must have the correct viscosity oil, and it all apparently goes out of the window. Either that, or because of the dilution of the oil with diesel, your going to suffer engine wear that was not foreseen when the development of DPF engined cars went into mass production. WHICH IS IT?

So it would be interesting to see if TDCi forum owners with DPF equipped cars could report back on this thread regards their engine oil levels.Are they ending up with more oil in their sumps than what they started off at?

Volvo who share engines with Ford are introducing new oil change fill levels and a software update. And better than me repeating second hand, I advise concerned owners visit the Volvo forum thread on the issue, there are some clued up guys over there. It comprises 39 pages of contribution. That's because it is a very active site, having over a thousand viewings and over 250 post on an average day. Suffice to say you will get the gist of the problem, Volvo's tight lipped response, and their on the hoof remedy to over full oil sumps, by reading the first page of the thread.


But just to show an example of the calibre of some of the contributors on the subject, I'll copy post from one contributor.His credentials are as follows



Anyway here are his first two posts in full: Note his comment on a possible dilution rate of 23.7%

I have presented the posts in bold type for ease of reading, but I consider it better to read said posts on the original thread.The Doc content starts on page six

 

Not only is it causing wear but if it gets too much diesel to oil mix and the level rises too high the engine WILL start to run on it's sump contents ending in a runaway engine that you cannot stop until it blows up requiring a new engine :( , much cheaper to change the oil and filter :) .

Strange how in three and half years of driving around town in my Mk4 2.0l diesel mondeo never did I have a problem with the oil level, even when I interrupted the regeneration. I know that Mazda 6's suffered from this issue but I never did...

Hi,

I am the same with my zafira 1.9 cdti never had this problem, but then again Vauxhall brought out an update so regen starts at a lower speed for town drivers,

Why haven't Ford done this for their cars.

Perhaps Ford, as a forward- thinking manufacturer, secretly want DPF equipped Ford owners to have their DPFs removed, thus eliminating the problem completely?   :)

Hi,

yes i think you may be right because diesels DON'T need them anyway YET, removing this DPF would solve many running problems on these modern cars.

Funnily enough I said as much in an earlier post I made on this thread back on 21st May 2013 ;)

 

So the problem is indeed real and ongoing, and think on never mind
diesel destroying the lubricating properties of the engine oil. In worst
cases, it could lead to self fuelling of the engine.......... a runaway
car. Just think wife's out in the car and that happens!

cuke me old muker,

 

what year was your Mk4 Mondeo? I'm not sure when Ford started fitting the later CDPF [I think it's refered to] being the one that is giving the trouble. I know Volvo being a Ford company at the time started replacing the eloys top up type DPF with the newer problematic ones. back end 2008 approximately. on the 2.0l model engines.

 

Anyhow, I just popped inside to check my emails and saw there were replyies to this thread I started way back. as it's a to bleeding hot 32C out here in Turkey. Bing weather reckons it will be 25C tomorrow, now thars more like it for me and the Misses.

 

Another ten days of this ...........but somebody has to do it............ :D
