The owner may saY 'yes, we have regeneration'. What next is down to the system: finished? if not, resume, if so and so.

In any case, there's a relay for the fuel vapourizer, which could be monitored with an LED, not very complicated. Still, WHY unless (like me) a teensy bit obsessed?

I admit watching and listening for regens. Instantanious fuel consumption, booming exhaust etc.
Not sure why. Still a nice big red LED would be nice.
