Hi all! We have been experiencing an issue on site where threads have been missing the latest postings. The platform host Vanilla are working on this issue. A workaround that has been used by some is to navigate back from 1 to 10+ pages to re-sync the thread and this will then show the latest posts. Thanks, Mike.

02 Sensor Issue

    Im getting P0130 and P2031 fault codes on my w203 c180. P2031 is very much a secondary issue I think, and P0130 refers to the upstream 02 Sensor Circuit.

    I took this graph from Torque+ and it seems the sensor is a bit lazy. Any views? New sensor or should I try something else.

    No one?

    Ran the car for longer with the scan tool attached, and on the over-run on a steep hill, the sensor flatlined at 0 and the Check Engine light came on.
