This is an O2 sensor failure with the sensor located in the manifold. The associated heater probably failed causing the sensor to fail.

first of all. clear the codes in the fault memory then drive it again. and check for new codes. if it is o2 sensor again then it could be many things other than the sensor. what you have to understand is that the car is making the decision of what it thinks is wrong. and the final thing in the whole process is the exhaust gas. if its wrong then the sensor will pick it up. it might well be the sensors at the current mileage, but dont rule out the obvious. air leaks on the intake system (EGR). etc. miss fires. the list goes on... hope this helps..

go to a garage to clear the code or take off the negative cable to your battery and leave it off for at least a hour to ensure the ecu is clear then hook the battery back up and try it.
