Any idea why car is not going into regen mode, could it be faulty exhaust temp sensor ?

I did a dpf clean a while ago but without going to regen mode it didn't work.
The first thing that came into my mind after seeing those printscreens was that "the regeneration won't start with those exhaust temps!" Possibly a faulty sensor. I think a new sensor is pretty cheap so you could try it!

I don't know which. Maybe both, maybe neither of them. I don't think it would be very expensive to replace both.

Hi, i don't now but i think it's better to try first with the dashboard.

Finaly it's just a maintenance reminder. You have no fault, the system wants just to say "Achtung, end of life is coming ..."

No autodestruction for the filter, i think tou've right to reset the dpf maintenance and see what happen.
