2008 135i n54 full stage 2 with 113km on the clock. Im currently getting a 2CA7 & 2CAB code which reads ( Oxygen Sensor heater 2 before Catalytic converter & Oxygen Sensor 2 before catalytic converter temperature.) I believe these codes relate to the heater ? im not too sure what the fix is here and if its okay to drive my car, do these codes mean my o2 sensor is done ?

the car seems to be running okay and the code comes and goes.
