DPF Regen times on idle, how lengthy? (CR170)

Hey guys and gals!

First time I believe I've encountered my DPF regen, not had a single DPF light come on though I have read they don't need the light to come on to enter regen mode!

The car is idling at roughly just over 900rpm and it's been like this now for exactly 45 minutes. Started at 08:38 now 09:23. I left the car to idle before I turned off as I never have turned a diesel off straight after getting to my destinations, I leave it to idle for 1 minute only, though jist as I went to turn the car off, the engine made an odd noise and idle went up.

What's the longest an idle regen can run for? I am absolutely gagging to get on the toilet after a night shift and heavy leg day at the gym

OK cheers mate it's been going exactly for an hour now, still at roughly 900rpm, if it does this when I start it up should I go for a good 4th gear 3k rpm run on the motorway?

Thanks for the quick reply too, my toilet is going to hate me lmfao! XD

Thanks Dan much appreciated, unfortunately no VCDS for me for now and I wouldn't know what to look for =)

Will rep you when I log on the PC later too!
