Holy Regeneration Batman

I know what you mean - we drove back from the T6F New Year camp earlier this week and right at the end of the 90 minute journey home the van decided to do a regen.Is it possible to start regeneration by pressing a button? Some times when you go on a long drive you know it will take 2h of drive why not make regeneration then...
VCDS programing + button?

Yes it can be done, well at least 10 years ago they could (VW) that is. When I was having my problems with my T5, I went out with a VW " master technician" a mechanic, who plugged his laptop in whilst we drove and did a number of forced regens. VW's conclusion was there was nothing wrong with my van, so I drove home, and it did two regens on the way back! I sold it not long after.
a mechanic (a person I know) controlled the situation of the DFP by PC .. after 25000 km and '10x100 ... so the frequent regeneration work to keep it clean .. now I do not worry anymore' ... when I am I stop and I feel he's regenerating I let him finish ... so that's okay ...
Yes. It works fine. But I just use Carista to monitor soot levels and take it for a longer drive when needed.Has anybody tried starting DPF regeneration by OBD CARISTA true the phone app?

I see here that it is possible. Thank you

4th gear and keep the Revs at 2500-3 for at least 10 mins. Instructions from VW for a manual regen!
My T6.1 keeps saying too much engine oil. Apparently due to turning the engine off during a regen. According to VW technician I need to drive in 4th gear for 10mins to do a manual regen, this will take the excess fuel away that has been collected for the initial regen that was stopped.
It doesn’t matter what gear, it’s the Revs. Needs to be 2000rpm+ to get hot.
The link to engine oil makes no sense to me. During a regen more fuel is put in along with some other magic done by the ecu to get the engine hot. It’s the heat (~600c) that burns the soot off in the dpf.
I have read about engine oil issues before, but don’t recall seeing an explanation as to why, so would be keen to understand the link.
The technician said the engine dumps more fuel in , and because the regen hasnt completed it raised the engine oil level. That’s why I have engine oil too high?
I’m not mechanical at all, so nothing makes Sense to me haha
Fuel bit is correct, but the rest doesn’t add up.
There have been instances with some manufacturers that so much fuel is dumped into the cylinders, that it doesn’t all get burnt, and finds its way into the sump (diluting the oil), and raising the level of the “oil” in the sump.
Mazda in particular had an engine that did this.
I assume this is what is being referred to.
My question would be is the oil level actually too high or is the level sensor faulty. This is easy to check on the dipstick.

I will check this tomorrow, but vehicle is only done 1k miles, but I’ve been doing short journeys recently.
thank you
You can do it with obd eleven too, I find it better to plug in and monitor the soot levels like @huw169 mentions above.
Sounds interesting and equally disturbing. I get that fuel could run down through the piston ring gaps, but that would need to be excessively over fuelling, and outside of the combustion point. Is the end point to get uncombusted fuel into the exhaust system and let the heat ignite it so the dpf internals are basically on fire?
I think I’m becoming obsessed with this topic.
Did a trip yesterday to drop stuff off. Monitoring soot levels as I went. I did about 450 miles and got 2 regens at about 250-300 miles apart of steady 70 mph driving. If I wasn’t watching I would never know it was doing it.
Got 30 mpg too, although dash said 27.

I think the end point as you describe it will be a catastrophic lubrication failure due to fuel dilution of the engine oil.
I’m amazed that a VW tech’ has mentioned to a customer that this is the reason for the raised oil level, while he is correct I doubt it’s the official VW line.
I’d like to hope that the VW solution isn’t to go for a long drive to flash off the fuel contamination through the crankcase ventilation.
F’kin hopeless situation IMO.
