    So I'm driving home from work in the early hours when the SES light comes on. I checked the codes when I got home, and have a "P2097-Post Catalyst Fuel System Too Rich".

    Probable causes, and possible fixes (that don't have me selling one of my kidneys)?

    Top off [or fill up] with regular gas and see what happens? for sure, it won't be "too rich" then, but, as you can see, yo no se nada! :devil:

    Fitted new post-cat O2 sensor, and had a buddy use his BMW tool to reset the adaptations. All good now.
