Just been out for another 40 minute blast.Here's some of the values from forscan i saw.

Cat temp 1 got to a max of 320 degrees

Coolant temp maxed at 90 degrees

Exhaust gas diff pressure 0.6 kpa idle up to 15kpa hard acceleration.

Dpf soot up to 71%

Dpf load kept going up down throughout the journey 

Still no regen! 🥲

Well, you know what my advice on clarity/vaporiser (still unknown) etc is as you don't seem to be getting anything new here (320  degrees - it ain't happening!)?

Going to book it in to get the vapouriser etc checked,beyond my capability im afraid.

We do have something new...15kPa should definitely be triggering a regen.

But also proves that the pressure sensor works.

Very odd.

Tend to agree but we still don't know if there's a vaporiser or not and if it is blocked it may be trying but can't start (the status of the process can usually be monitored in Forscan - well it  can in mine)
Again, clarity on the equipment fitted (giving the method of regen) is now crucial otherwise further speculation is futile?

Im going to attempt to test the vapouriser myself,is this kit suitable? 

Ideally if that does vacuum AND pressure (some only do vacuum or only pressure useful for many applications and much cheaper than garage time) then you'd simply clamp fuel line to avoid need for priming. Then connect to vaporiser with a bit of pipe then blow down it (you could even try with a long piece of appropriate pipe and simply blow down it.)

Are you now certain that it has a vaporiser?

They are available to buy?? While your about can I ask you your thoughts on why I havent recieved an error message on forscan about the cat temp not getting hot enough to start regen,ive read several posts where people get the error code if theirs isn't getting hot enough.

Look on e-bay, suspect they are cheaper than that.

AFAIK, the general alert comes when the differential pressure and/or soot loading gets too high but I can't explain your situation other than it hasn't seen the need to regen, despite everything you have said?

Yes its a weird one.The exhaust is obviously not getting hot enough (320 degrees max) so I'd have thought I'd get an error code pop up.I'm going to take it on a much longer journey than I have been doing,I'll know then if theres a problem,thanks for your help.

Good Luck on that, I would still like to know if it actually has a vaporiser which would solve this ongoing mystery.....(especially if it was checked and found faulty or otherwise)?
Sorry to be a nag but details are important.

Yes,after giving it more thought I've gone back to the plan of having the vapouriser looked at.Not going to attempt to do it myself so getting it booked in today.Will let you know the outcome.

Yes but are you sure it has one as you still haven't said (wouldn't want to see anything wasted)

Trusting google and the fact they are available to buy.

I had 3 Focus 1.6 TDCI's that didn't have a vaporiser...

That's also not Google, it's just AI plucking bits out of other websites.  Please don't rely on that for anything important in future.

Good news! I was on the 5 mile journey home from work today and I noticed i was getting higher exhaust temp than I have been getting.So took it a blast down the motorway and thankfully has done a regen.

Hasn't emptied completely though as it has always done in the past,the closed loop load reading went down to 0% but the open loop reading stopped at 23%??

Does this mean it could do with a flush out?

Yippee!
BUT IMHO, there is far too much confusion here.
The soot figures are from calculation (there is no way the exact mass of soot can be measured directly)
I don't think any cleaning is needed.
If there's low differential pressures as above then you could reset the DPF parameters but there's no justification for doing that.
I don't think it needs anything done at 23% and the open and closed loop difference isn't significant.
The other figures except the  stated 1500  mile gap between regens appear acceptable.
If it is now regened (what triggered this, pressure?) then you may well be worrying unnecessarily.
BUT 
I'd monitor at standard conditions, not just random times, the DPF PRESSURE (this is the only direct evidence of the state of the filter) as said above, temperatures and soot loadings on a regular basis so you establish what is going on (until you can hopefully stop worrying!)
The regen method i.e. presence of a vaporiser or not STILL  needs to be determined as there may yet be an intermittent fault or not.

Please let's have clarity!

You have nothing to worry about.

I have already shared this in a previous post, is this not proof enough that it has a vapouriser? Could there still not be a vaporiser on my car even though they are available to buy for the exact same vehicle?

 

I'll let you get on with whatever you decide.

Hope you can find a pattern and ideally there isn't a problem and you can stop worrying.

As has already been said before by @TomsFocus,  not all 1.6 TDCI's Focus were fitted with a vaporiser.

Just like you can buy heated screen wash jets for a 2013 Focus, it doesn't mean that yours will.

The DPF is at the front of the engine on 1.6 TDCI.  It would have taken far less time to just look at it than to keep posting screenshots from unreliable sources.

APOLOGIES TO ALL

I realise now how much of a dumb ***** ive been.Not going to go into my train of thought regarding the vapouriser but realise now how stupid ive been!

I will check to see it has a vapouriser or not,and if it has maybe get it cleaned out if I notice any issues regarding low exhaust temp.

Thanks for all your input.

A bit of a necropost but I was reading through this and thought it was worth it to add:

I’ve seen others say the euro 5 1.6 TDCI waits for the soot level to be > 80% for a regen to occur, and I can concur that this is what my 2014 Mondeo does.

I have a live scanner so I’ve been looking at it during a drive.

If I’m blasting it in 4th gear 3000 rpm on a motorway the catalyst temps don’t really exceed 350C, whereas in 6th gear they go above 400C easily, so don’t bother revving it high for no reason like so many suggest is necessary, it’s not, it’s just pointless for the DPF, maybe you’ll clean your valves and EGR though? 🤞

It will basically never reach temps high enough for passive regen (600C) unless you find a very long hill, or drive way above the speed limit for a motorway so it’s normal for the soot to go to about 85% and then regen down to low 20s. And these regens work whether the engine is under a high load or not. So if you’re in town as long as the engine is warmed up it will still do it.

For me, it actually decided to do the regen just as I had given up trying to force it to regen and was decelerating off the slip road (soot level was about 83%, it went down to 22% in a matter of minutes) .

TLDR: Just let it do its thing and don’t worry about it. And if you’re expecting passive regens, maybe consider moving to Germany 🤣.

While we're bumping an old thread...  My car was taken to MOT last week, after having sat unused for a few years.  On return, the fans were running, but as the driver wasn't familiar with regens, they switched it off, and the fans continued for a few minutes.  I assumed that meant it was mid regen, so next day I checked the soot levels, expecting to need to force a regen, as it won't be driven on the road again anytime soon.  (Owned the car 7 years and never had reason to check before).  Anyway, looks like the regen did actually complete.  The time-since-regen counter was right down to about 30 seconds, which is about the length of time I'd had the engine running to plug in the diags.

Interestingly, measured soot seems to be a minus number.  Not sure how that works.  Differential pressure is very low.  (Note VCDS measures in hPa, not kPa).  But it also measures soot loading in grams.  Can't say I've ever seen that in Forscan?  Do any Fords show soot weight?  Just interested to know what the expected weight would be after a completed regen.  (I did read that forced regen can only be done on these when between 30-40 grams, so not possible to force a regen currently).  

First pic is idle, second pic is 2500rpm (stationary limiter).  I know it's not the best test but it's the best I could manage at the moment.
