Did a few searches on here and think this might be something to do with the P0410 code issue that many XF drivers seem to have experienced. I think this is due to the either air inject pump not being registered by the ECU or issues with the pump. What I have noticed recently that I am pretty sure was not happening before was that I can hear a whirring for about 30 seconds after starting the car from cold, I assume this could be the air pump. Does this mean there are issues with it?
