So, if it's the heater in the probe then the probe needs replaced. I can check the fuse, if I knew where/which to look for. Any thoughts?
The connectors will require so much removal of other parts that I might as well swap the probe at that point. Bosch probes are going for about $130 now.
I'm still scratching my head from 2 posts ago when it was suggested my bank 2 is on driver side, though the N52 engine in this scenario is a straight 6 which, I thought, puts the 2nd bank in the rear for cylinders 4-5-6.

Sorry to confuse you. My original post was about the V8 engine in my X5. Just assumed you were talking about a V8 also. In your inline 6 engine, the bank 2 pre-cat sensor is the one closest to the firewall on the exhaust manifolds (#2 in the RealOEM diagram). Should be easily accessed from above. Might need to remove the parts that hold the weather stripping and A/C filters near the windshield for easier access. Don't worry about the heater probe fault. Just replace that sensor.
