My Ride: 535i 09

I recently got 2C39 code, which is Lambda probe in front of catalytic converter, dynamics. It is the only code that appears. I changed new spark plugs first since it due after 45k miles, no luck. I ordered the sensor and replaced bank 1 sensor 1, then the code is gone
. After 1 week of driving, engine code popped up again, same code
. I'm clueless now. Would anyone shed some light to me
. My car is at 115k miles right now.
