Re: Jump in Calculated Soot Mass

Hello, Bought and registered the VCDS and did a full scan. I was told to check the two pipes for splits that go to the sensors but all seemed ok, I blew down both pipes and both seemed similar. Took off the sensors and blew into both pipes, checked the resistance on pins 1-2 1-3 2-3 and all seemed ...

Hello, Did you manage to solve the problem or find out why its happening like this? Im in a similar situation with a Passat B8 2015 2.0tdi 150hp engine code CRLB. 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...
