Hi,

Does anyone have any ideas what noise this is?

I suspect its coming from the alternator bearing or alternator itself and I only really notice it when the car is at idle.


Thanks

Mitchell

Hello,
After further investigation the noise seems to be affected by the air conditioning. When the air con is on all of the time the noise is not present, when the air con is off the noise is there all of the time, and when the air con is on auto the noise is intermittent ( as shown in the video below).

The noise seems to occur when a drive belt pulley cuts in and out, any idea what this could be?

Here is the video from today:

Regards

Mitchell
