2008 Cooper o2 code - Bank 1 Sensor 1
 

Hi, new to the forum and have my first ask. I recently bought an '08 Mini Cooper hatchback and now I have an error code that is for the Bank 1 Sensor 1. The car is running smooth, no oil leaks, no overheating. It's at 95k and the sensors tend to need replacing around 100k? Any other ideas?
