How often are your vans doing a regen?

[osman]

I’m getting regens happening almost once a week at the moment it’s a pita really annoying … I would say my driving is varied enough I’m doing 30 - 50 mile journeys several times a week and also a fair amount of short restricted to 30 / 40 mph journeys in my local village .. last week I did a run to Plymouth and back to Southampton so I’m really surprised to be sat in my van yet again listening to it over rev and watching it burn up my diesel yet again I’m watching it using Carista and it’s taken about 20 minutes so far to get down from 24.6 g to currently 14.73 g of soot level … is this normal ? It’s seems to be happening too frequently

Mine's a EUR5 T6 and regen scared the cr@p out of me the first time it happened since I upgraded from a 2006 Vivaro that was to old for all this tech. White smoke, high tick-over etc - thought the head gasket had gone. Now that I've got a Carista to monitor it, it regens about once per tank, takes 15 minutes, a light comes on the dash to say regen being attempted and I make sure to take it for a good run on the dual carriageway. I can live with it now I know what it is. I have to say, though, the idea that the solution to air pollution involves extra high-revs driving seems... mad.

This T6 is my 6th VW after 5 caddy’s which all had DPF

My last caddy was a 2018, like my T6 but regens where 15 min max and maybe every 100-150 miles

This T6 is 60-70 miles and can be 3/4 times a tank always lasting 25-30 mins and they just won’t give up if I stop at any poinT

I’m getting so fed up with how much fuel it’s using, how it drives like shit during and why it’s so often.

Im so fed up I’m tempted to make a complaint with it not being fit for purpose

I have had VW out to me twice to do regens on the spot as they just wouldn’t stop going

Anyone able to help? So peed off with it

Have you had any engine lights or AdBlue problems? I noticed mine was regenning loads when the EGR was faulty, and the front pipe leaking.

In 40k miles and 4 yrs, I can't say I've noticed this happen. Which light comes on?
EDIT - the exhaust with the dots. Will look out for it. I do next to no urban type driving.
I have noticed that the auto stop/start can be de-activated, but this is usually when the A/C is on and happens on the petrol Polo too.

a) Light comes on when you trigger regen through Carista, or b) light comes on automatically and you take it for a spin?

If b), do you go home when light goes off?

Sound to me like your van is not always getting a full regen, or more concerning, the type of running around you are doing in it isn’t very Dpf friendly.

I did 130k in my old T6 and never once noticed the regens, but I do 99% motorway miles.

Not sure if this has been already said but it needs more than a quarter tank of fuel kept in it too, as for some reason I can't remember, it affects the ability to regen...

I did a run to Plymouth and back to Southampton so I’m really surprised to be sat in my van yet again listening to it over rev and watching it burn up my diesel yet again I’m watching it using Carista and it’s taken about 20 minutes so far to get down from 24.6 g to currently 14.73 g of soot level … is this normal ?

Please clarify - what was going on with the van during the 20 minutes? At standstill, engine ticking over (the elevated 980 RPM)??

If b), do you go home when light goes off?

Hi. Light comes on automatically and I take it for a spin. Yes, I did. I’ve learned how long it takes and turn around before the light goes off though. Light goes off half way back. Then I check soot level with Carista.

Is this android only?
Anything for Apple?

Edit. My bad. Should have read it all...

Carista works fine on Apple & DPF soot content works too

Soot level should be ~6-8g min. Passive regen only starts at 30g but my light does not come on.
If your light is coming on it is above ~35g and has been trying to regen but can’t.
Do you run it below1/4 tank of fuel?
Do you drive it hard when cold?
What year is it?

When light goes off I believe it is just getting back below 30g, but it is not finished.

Hi. Mine seems to aim for about 10g. Each time the light's come on, I've measured level at somewhere around 30. When I get home after a spin, its 10-11g. The user manual clipping here seems consistent with what I've seen. It does get used for short journeys - sometimes to school and back twice a day for a week and only really gets a good run once a week. Never below 1.4 tank, never driven hard when cold. T6.0 2016 plate, T32 150bhp. Next time the light goes on, I'll run it further and see if it goes to 8g. I'll post here. I too really want (need!) to understand how to deal with DPF. That first event has scarred me.

BTW - you got me thinking whether mine's a courier version as it used to be British Gas. I've checked the build sheet, and the only potential is this entry:

Market-specific vehicle type: AW7: CO2-reduction version

I don't know if that's just standard, perhaps referring to EUR5.

You know about the high tick over during regen? Sits at about 1000rpm if it’s still doing it.
I only ask this stuff as I’ve never seen my light on unless I’ve actively triggered it through Carista.

Hi. Yes - first time it happened it was on the drive warming up on a morning - tick over suddenly raised to about 1100 and it sat there smoking and stank the place out. I’ve never triggered through Carista - only used it to monitor soot level.

 

[oldiebut goodie]

Odds are that he has one of these special courier vehicles seeing as his behaves as above, strange that no-one else has come across one of these specials before though. Ideally I reckon that most of us would rather that our vans gave an indication like this rather than finding out when we have got home and parked up.

 

[CJW]

I’ll keep more records and post back. A close friend of mine had to abandon a trip to France on holiday because of a DPF regen issue on his car. Cost him a grand. Not a VW. It’s kept me interested in what’s going on in the T6.

I seen and heard some right wrecks fire up on the the ferry after docking in St Malo!

If im only doing short journeys then mine will regen every 150 miles or so, and upto 300 on a long run. I believe that’s typical.

 

[CJW]

That sounds about right for what happens with me. After we were discussing this last night, I went to monitor the soot level because the van had a 30 mile run yesterday but the last 'dash light + A-road spin' was a few weeks ago. It was 11.2g. Would suggest although short journeys pile the soot on, even a medium run out does a decent job of reducing it.

 

[huw169]

Yes. Cold engine generates soot in far greater quantities than warm engine. My main journeys are short, so I just keep an eye on it. On a plus, the EGR should be clean.

@mmi has seen evidence that soot can reduce a touch under certain normal non-regen driving conditions. I’ve never seen this though on my van. It’s always increasing at varying amounts until it hits 30g then just regens.

I run Vpower too, just cos…
