Took off the sensors and blew into both pipes, checked the resistance on pins 1-2 1-3 2-3 and all seemed ...

The fact that soot measured only decreases when idle during regen is even more odd than our behaviour.

Hello, I have been to the local VW dealership at the beggining of this week and explained the sympthoms of often regens(last 3 regens were at 30-60 km of city driving), and they said its indeed too often and they will look into it.

I have each time a sudden and instant spike in soot mass calculated from 12-14gr (after 90-110km from last succesful regen) to 23-24gr ,a...
