I keep getting this code and can't really find any info on it.

The technical description is: oxygen sensor after catalytic converter, signal short circuit to B+

That site will give you BMW fault code descriptions, conditions, and sometimes a service plan.

Most likely it's a faulty O2 sensor after catalytic converter or a fault w/ corresponding wiring.

Check wire Connections, make sure ground connections are secured and cleaned off.

This may be the costly solution, after inspection connections, I would suggest you clean the 02 Sensor, before paying for a new one. After cleaning, check to see if code reappears. If it does, you may need to replace it.
