automatic regen question
I just got my truck and I got the manual regen option. I read in the manual that there is Operator Commanded Regeneration with Automatic Regeneration Control, which seems to imply that you can turn off the auto regen. I can't seem to find anything in the settings about this. Is this a separate option from the manual regen option that I have?
I ask because the other night I was almost home when I got the message that the DPF filter was full, so I decided I would drop of the wife and kids and drive it and see if it would do the auto regen thing. When I stopped and put it in park I got the message asking if I wanted to clean the filter with the manual regen, I didn't do it as I planned on driving it out on the highway. Somehow it dropped down to 95% as soon as I left the house, before I even got up to speed on the highway. I drove for probably 15-20 minutes at highway speeds and it never dropped below 95%. shouldn't it have started dropping?
I am wondering if it is possible that the auto regeneration on my truck is turned off. another thing that makes me wonder is the fact that I did quite a bit of driving that day and highway speeds and never saw the percentage drop at all. In the manual it says it may fluctuate up and down due to active and passive regens but mine never dropped, just gradually went up.

Why don't you just leave it in auto and let it manage itself?
This is something I never bothered with in my TDI Golf and there were never any issues in the years I owned it.
I'm keeping with that philosophy with the truck. If it were that big of a deal I'm sure the engineers would have put in a ton of interlocks to make sure you made it happen...

By no means am I an expert on this particular feature but it was my understanding that this wasn't something you could do on the fly. It was something you could do when parked like the dealership can do. Hood up, activate the regen, rpms go up, fan goes crazy like a 747 and it regens in park in the driveway (for those who can't complete them in full).
Does anyone know for a fact that you can tell it while driving at any time to trigger a regen?
