DPF REGEN LIGHT

[zzattack]

That's not a bad plan but it'll be pretty tedious. If you haven't looked at either bus so far, it might be a bit overwhelming. There's a ton of messages being passed around. Don't expect to find what you're looking for without some rigorous filtering set up. On the HS bus the traffic volume is too high to simply log over serial. Longer periods of logging would require an sd card.

I'll see if I can force a DPF regen over MDI. If so, it'll be much easier to track precisely which messages are relevant.

Apparently the happyblue module can show this, so we can also look at the firmware on this device but my guess is this'll be even more tedious.
