In Topic: Winter Diesel Additives, 1.6Tdci Blocked Fuel Filter

05 April 2013 - 07:50 AM

Probably the last word on this subject, I have received an official reply from Ford Technical Information Centre who state...

 

“…..This concern is being investigated by all vehicle manufactures at present, not just Ford.


The concern is noted to occur in cold weather conditions.  It is suspected to be caused by a differing bio fuel composition between different fuel manufactures.  When the differing bio compositions are mixed in a tank, a reaction appears to be happening under cold weather conditions, forming a jelly like substance, which produces a restriction in the fuel filter.

 

However this is still being investigated & we are unable to provide a definitive answer.  The above explanation is what we believe to be happening at this stage of the investigations.  It has been confirmed however to be a fuel issue, rather than an engine of duel fuel system design concern.

 

I can also assure you that all vehicle manufactures appear to be reporting the same concern this winter, not just Ford…….”

Hi Guys, thought I would try & bring this back to the original thread.

 

I'm not trying to say one brand is better than others it's about why the fuel waxes in the filter on the 1.6tdci Econetic at low temperatures (albeit not very cold).

 

I've looked at virtually every other thread & on one there is a guy with exactly the same problem with the same car.  He has taken it further than me & has posted pictures of the fuel from the filter which has waxed & fuel from the tank etc etc. 

 

I've learn't a lot recently about the cloud points of fuel, CFPP's, when the switch over to summer fuel is - BP say it's the 15th March, but can not say if the date is flexible due to local weather conditions.  Also the lower the micron number is on a filter the lower the CFPP figure is, anybody know how fine the Econetic fuel filter is?  And it's not only Fords - but maybe it's the Ford/PSA engine that is also in Peugots & Citroens AND Range Rover Evoques as on their thread there is someone who also had a blocked filter in the cold due to waxing of fuel & has been told it's a common problem.  His RAC man even carries more fuel filters in his van when the weather is cold.

 

There is something specific such as a design flaw or just a collection of a few events that when combined cause this problem.  Is it the route the fuel pipe takes from the tank to the filter, is it subjected to ....something?? Is it the increased levels of biodiesel in the fuel (which don't like the winter & don't react the same way to the winter additives), by increased levels of biodiesel I mean more than the minimum required by law.  Is it the Econetic engine & it's supersensitive design (finer fuel filter, increased injector pressure).  Is it condensation in a half fill tank (but this would happen to all models - but the Econetic filter is finer!).

 

We need a Ford CSI team to sort this out as it is way above the supermarket versus big brand fuel debate.

 

By the way if you are interested the link to that other forum is: http://www.talkford....s-cold-weather/  only look once though & then back to this one.

Hi Stooge75, I don't think you've grasped where this thread has gone.  No one is saying supermarket fuel is rubbish, it has to meet a certain specification.  But sub zero temperatures in the south in mid march may have caught a few garages out who had already switched to summer fuel.

 

For the record tankers have more than one compartment & can therefore carry more than one product.  If you see a tanker delivering to Asda, Texaco & BP then they can not be selling much to only want a part load ???????

 

As you would expect this topic in general is on many other forums, especially at this time of year when many people drive off to the Alps on a skiing break having filled up in the uk beforehand with summer diesel only to encounter problems the other side when the temperature drops to -5 degC & beyond.  Be warned.

Interesting replies - thanks.

 

My engine is a Euro V emission standard engine. To meet strict Stage V emission regulations, the Duratorq TDCi engine has been comprehensively revised including new solenoid fuel injectors, now with eight smaller holes, work with a maximum injection pressure of 2,000 bar for improved fuel atomisation, compared with the former six-hole injectors and lower 1,800 bar pressure.

Not my own words but interesting point about the smaller nozzles.

 

There are some who say supermarkets add more bio-diesel to the mix than main brands, to lower the sulphur content.

Low sulphur diesel has an increased wax content, the result of this increase could include higher cloud point (where first wax crystals form) & greater winter wax gelation, which is also likely to increase fuel filter plugging.  Low sulphur diesel with more than 5% biodiesel has a high wax content, which increases wax gelling = premature filter plugging.

 

Both of my breakdowns happened during sudden drop in temperature to -4 / -5degC.  Maybe the garages were caught out as the winter additive is added at the station & I had a tank full of fuel which had no additive & was therefore susceptible. My last three tank fills have been Sainsburys City Diesel.

Thanks for your reply jeebowhite, apparently this is what Ford themselves have told the dealership & it is not what one of their mechanics have said.

The first time it happened a new fuel filter was fitted by a main dealer near where I live & this time 4 months later another fuel filter has been fitted by another main dealer near where I work.  Two different Main Dealers both diagnosing the same fault.  As I said above it's common only to the 1.6 diesel engines as these have a much finer filter (????). 

The fuel filter was clogged & has been changed twice, I'm doing on average a tank of fuel a week, approx 600 miles so there is plenty going through it.

This time the RAC plugged his laptop in & (apart from not having my engine as it was too new for his software) he did find a coupel of codes when looking at another 1.6 diesel for a Fusion - these codes were related to low fuel pressure at the injectors etc, I have them written down if you want them.  But he also suggested it was the fuel filter & has seen it a few times in the cold weather.
