Could it be the fan ? playing tricks on you hearing?
could be my hearing i am getting older

don't i feel daft, it was the bloody fan.lol. thanks for the help y'all....
on a side note it's booked in as the ACC front assist isn't working, yet the lane assist was today, and it will be getting turned off (lane assist) as i was going across a t junction with traffic lights and lanes and all of a sudden the car turned right (it was confused i think)
