Good evening I was wondering if anyone could help. We have a ct200h on a 18 plate been a great car so far but the other day started the car and there was a noise the best way to describe it is it sounds like a phone that’s vibrating lasts for about 10 seconds then stops . The really strange thing is it only does it when the car is started first thing in the morning . The thing is it only started after the service warning come up on the screen? Not sure if it’s connected.
