O2 code only after long drives
09 Clubman non S
I am receiving an code for the 2nd O2 sensor only after a 1.5+ hours of throughway driving at 65+ MPH. This code does not appear any other time. I clear the code and it will only come back on the long throughway trip. The code is 2A74 per my Foxwell scanner. Car seems to run fine. Looked at the wiring and nothing appears loose. It is a Bosch 02 sensor and was replaced a year ago.

Update. The part was under 1 year warranty. I was able to exchange it at no cost and reinstalled it. Took a long drive (good excuse to get out for a 1+ hours). No codes. The old one did have some black soot on it when I removed it. How normal is this for the MINI? Is it running rich? This is an NGK sensor.
