I'm only left with 2A3F and 2A77
If everything is fine(e.g. no corrosion on the pins of the connector, chaffed or cut wiring) I would replace the O2 sensor. If you had the means of checking the wiring from the 02 sensor connector to the DME for reistance and shorts to power or ground, I would do so for good measure. But I highly from experience believe you need an O2 sensor. Seen this many times.

Also see if you can get a replacement Bosch sensor from a local auto parts store. Its much cheaper and the SAME exact sensor without the BMW stamp on the connector.

Let me know the outcome. Best of luck to you. I hope this has helped.
