    2E9F oil condition sensor, ?

    I'm having the issue with car running like crap and only code of 2E9F after multiple clearing of codes (BT cable). I did replace the vacuum lines by the oil filter housing (one seemed bad) and diverter valve O-rings, but the issue is still there. My next idea is to replace all remaining vacuum hoses, and check charge pipe next?

    In short it only happens on harder acceleration (not even WOT), check engine light comes on, car starts running like crap. Then restart the car and in most cases no check engine light and it runs normally.

    I do have wedge flash now, but I don't think it is related at all as my car was "choppy" on WOT when stock and even more so with Procede. It seems like something that was broken, finally broke some more, but not all the way yet as I can still drive normally.

    I can try logging with BT, although not sure how as never done it.

    Car is 2009 E90 335i auto with 102k miles, about 25k+ on the plugs (only 5k or so with flash).
