Manually Start A Regen

[SlothBurger]

My regens on VW T6 Kombi are starting about every 300 kilometres but I've often been coming near to a journeys end when they start - i.e. I drive into our road near home and the bleddy thing starts regen. Then I have to keep driving it to finish the regen.

I have the DPF Monitor app and I can see the soot buildup to 80% (24g) but is there a way to start the regen early if I'm getting near the end of a journey and see it around 76-77% could I trigger it to start somehow?

Not something I’d do, injecting extra fuel for the regen’ more than required isn’t good for the fuel economy or the engine / oil.
Carista can force a regen’.
I use a permanently connected device to monitor regen start / finish and grams of soot loading. MS DPF Control, there’s a thread regarding it on the Forum, I believe this can also force a regen.

Nothing is easy is it. Last few times I'd already been driving for 2 hours on journeys and then the regen coincided with reaching the destination so have to keep going and do another 20 minutes loop. Then I catch traffic on the way back so a 2 hour drive turns into 2 hours 45 minutes when it should be done at 2 hours.

It’s like it knows… lost count of the number of times I’ve driven over 300 miles back from Scotland, or for a couple of hours from somewhere and the regen starts just as I arrive home or first thing next morning when I nip to the shops so have to jump on the motorway until it finishes

I think you might be overthinking this- it will just finish the regen on your next journey.

It's nt a good idea to stop the engine when it is doing a regen. However (after talking to a VW Assist guy), if it is doing a regen when I get to my destination, I wait until the van realises I've stopped, it interrupts the regen and the revs drop from the regen 1000rpm to the normal 800rpm then wait another 30 secs or so. This means what I turn off the van isnt injecting diesel so reduces the risk of oil dilution. The van completes the regen as soon as I set off on the next journey.

The regen’s on my Euro 5 CFCA only last 6 minutes at 70MPH, just under 2000 RPM, the MS DPF Control is a great monitor / control device.

Yes, the difference between my last van, Euro5, which I sold because of the Greater Manchester clean air zone (which ironically is now not coming into force ) and the replacement Euro6 van is massive. From memory not only was the euro 5 a lot faster, it happened about once per tank. Euro 6 regens last about 20 mins and happen every 160 -200 miles or so. So van is less powerful (150 to 180) and uses considerably more fuel, how can that be better for the environment?

Trouble is, I do mostly shortish journeys and, like the others have said, it usually likes to kick in just as I'm getting home. My next journey is more likely to be short as well so I pop in the house, tell her indoors I'll be another 20 mins, she rolls her eyes cus tea's nearly ready and orft I go. I've only had car since May and would rather do that than risk the brain box throwing a wobbly and coming up with emissions faults.

Just did MPG check and with quite a bit of dual carriage driving this time, 80 miles towing 1500kg caravan and 2 regens (started one shortly after topping up) it's returned 32 MPG over 490 miles. We've got 2018 102ps 8 seat transporter.

I'm lucky, I have a long single carriageway road about 2 miles away where I can drive in 4th gear 50mph to the first layby - nice easy access to turn round - and back. About 10 miles and it's completed it. I can put up with that!

In 6 years of ownership I've never noticed my Euro 5 T6 do a regen. No raised idle or any other signs.
The inside of the tailpipe is squeaky clean though so the DPF works fine.

I'm new to all this emissions stuff but it wasn't long before I cottoned on. We were towing our caravan and I started to smell something which I assumed was coming from farmers muck spread on the fields which of course prompted me to ask herself if she'd farted and from her reaction I'm fairly confident she hadn't but soon thereon after we stopped for a wee break and there it was, in all it's glory, fast idle, noisy fan and pong still there. I daredn't stop it so asked her to be smartish about her business and orft we went again... mission accomplished. Made my holiday that did, knowing it were doing what it were supposed to

Not just me then - though I've not taken it as far as checking any tailpipes.......
