Hi all.

I have been idling for 3 days in 75/85°f, I haven't been idling when it gets down to around 70°f, so overnight. My truck hasn't asked for a regen once ! Is this due to the high temperatures? I'm concerned I'm going to leave tomorrow and spend an hour doing a regen when I hit the highway. I can't force a regen I have tried a few things, pressing and holding the switch, turning the switch to manual for an hour, turning the ignition key of and on 3 times with starting on the 4th and holding the switch. Nothing.

Any help is greatly appreciated.

It more than likely is fine. If you can't do a forced regen, it doesn't need it. At least it doesn't in my 2019 DD15. Never had one run an hour....20-30 mins usually and once 40 on an older truck that I had to idle a lot in the heat. It may regen as you go down the road.
