Hello to all motor enthusiasts, I would like to keep my 120d Bj 2010 as long as possible without much to do. Since the scheduling with a coder is cumbersome for me, I would rather keep the free burning of the PDF in the eye differently. But how? Can someone tell me with which driving cycles it is likely that a free burning is initiated and how long it takes then and at which speed it is interrupted prematurely? Which driving time min. Which speed is min. it is almost the same with all 2L engines? Has this topic already been dealt with extensively. I would also be very grateful about a link
