Still a contentious issue, even with modern diesels...so..
1) Why can't there be a light on the dash that tells you when a regen is happening? I know the signs in my car because it idles at 1000 revs instead of 850, but a lot of people don't seem to be able to tell.
2) Why can't there be a button to press to start a regen when it's convenient to the driver? I can drive mine to Liverpool and back on the motorway and the fickin thing decides to do a regen on the way to Asda the next day. If I had some means of telling it when to do it, i.e. on the motorway, then even if it wasn't full, it would purge what was in there.
Surely this is not beyond the bounds of modern technology?

No, but it is beyond the average modern driver. ::)

You are only the owner. >:(
You have no say in the operation of your vehicle :-\
The manufacturers say they know best :D
Its how its always been :'(

Yup, intelligence of the modern driver or lack of is the issue. Suspect some struggle to know where to put screen wash, let along what DPF is or does....

How about we don't use fuel designed for canal boats and Tilley lamps? ;D
-
Because they found that many drivers, who have been conditioned by engine fault lights, turned the engine off when the regeneration light illuminated. What's even more common is drivers/owners who have no understanding, and even less interest in how their car actually works.
I know that's a problem that wouldn't exist if they read the manual, but how likely is that?

Be fair, Kevin.
Derv has plenty of practical uses. I mean derv and cement mixers, and derv and farmyard machinery go together like eggs and bacon.
However, for the right-thinking among us fuel fit for a lorry or bus should never be used in a car. :)
STMO only has himself to blame. ;D

Mine has a great habit of starting a regen after 30 miles, when I am now 2 from home, leaving me to drive in circles for a couple of minutes until it finishes.
It normally manages this after a night shift when I just want to go to bed
Law of the sod is alive and well!

When we first started to drive we could only afford cheap crap that broke down a lot and thats how I learnt about the workings of a car ;D

The answer is to drive a smokey old diesel that dosn't have a DPF! :y
-
The answer is to drive a proper fueled petrol engine car after having the deviled fueled one cubed :y

some interesting reading here
What happens if your car starts a regen just as you are getting home?
-
Personally I always drive until the regen is complete.
I find it fairly obvious when its happening, but I know others think theirs has never done one!

Surely this is a basic flaw with lorry fuel and a DPF. :-\
Most people want to switch off the engine and get out of the car when they reach their destination........unless you own a Ferrari or Lambo in which case you may want to keep driving until you run out of petrol. :)

Me too. Takes about 5-10 mins. Mines an auto so I use the manual gears to keep it over 2000 revs. I know it's finished when it starts idling at 850 again.

So, correct me if I'm wrong.
A two minute drive to the corner shop becomes an expensive 10 minute drive as you need to spend another eight minutes driving around waiting for the DPF to 'do it's stuff'
I'm slowly going off the idea of buying a derv powered car. ::) ::) ;)

No, it won’t start a regen after just 2 mins. It must have reached operating temp for starters. :y

What happens if a whippet loving derv owner from the North of England says "fu*k it, I'm switching the engine off right now because Emmerdale Farm is just starting?".

How often do DFP 'regens' take place?
I was under the impression the 'diesel enthusiast' was inconvenienced about once a year or every 12000 miles. I'm now guessing it's more than that.

About every 2-300 miles. It's no big deal, it just does it.

You will soon come round again when the resale values plummet as successive governments punish diesel and then petrol drivers over battery powered cars. :y

I'm hoping hydrogen fuel cell cars take over from petrol and derv when it finally happens. I don't think electric 'milk float' like cars are the way forward.They are the distant past.
Anyway, by the time this all takes place I'll probably be six feet under and past caring. :)

I hope you have made a note in your will to specify petrol powered hearse. Imagine the ignominy of arriving at a sedate pace and then the mourner having to wait while the hearse did a regen , the finish of which would be marked by a puff of white smoke issuing from the rear of the vehicle ( a 2.2 stretch limo diesel XF?) ;D ;D

Sounds like something from the Dave Allen show. ;D ;D ;D
-
You'd be late for your own funeral as when arriving at the cemetery/crematorium the hearse driver would say "hang on a minute I'll have to drive about for another 10mins or so while the regen's complete" :D ;D

The XJ is the first car I've had with DPF. I've yet to notice it doing one, though I suspect it must have done by now.
It has lights on dash, but believe it only illuminates (amber) if it has really needed to do one, but not been able to. Or red if it really, really, really needs to do one. I've only seen lamp come on as part of the ignition sequence.
That said, given my piss poor economy, maybe its constantly doing one. When I got home the other night, it certainly stank when I got out.

Yes, it does stink after doing one. If the astra's DPF is getting critical after a few partial or aborted cleans, a message comes up saying "Keep driving, filter blocked" or similar.

Back in 2012 we had a new insignia sri estate and it was a pain in the arse to be honest as no matter how long I kept the revs up driving etc it would constantly be regenerating no matter how hard I drove it. and in the end was glad to take it back to the dealer and hand them the keys.
-
On the insignia there is a mod whereby you connect an LED to the heated mirror wire and it comes on when it’s doing a regen.
http://www.vauxhallownersnetwork.co.uk/index.php?threads/insignia-dpf-led-indicator.609721/
Not sure if this would work with yours. I have never noticed it doing one on mine in the 7 months ive had it. I have an icarsoft code reader that can tell me how much % soot accumulation and also miles since last regen which is normally around the 300 mile mark.
-
Having to regenerate twice per tankful seems rather poor :-\
-
I was “dialled” into the VW and noticed it’s regens, but with the Zaf I’m yet to notice it. :-\
