Strange high pitched noise

[Alex Michaels]

Hi,

There is a strange high pitch noise coming from somewhere outisde the car when driving (i can only hear with the window down), and seems to be mainy at around 40mph, almost sounds like brake squeel from my pads (i've got Ferodo 2500's).

Any idea what this can be? I've had a look at the discs etc closely and no signs of any damage, is there anything common anyone on here has expreinced before?

Thanks,

Alex

Is this with the drivers window down?

If so mine does it as well, seems to just be the air travelling over the wing mirror then into the car.

It's the wing mirror, on the passenger side there's the outside temp sensor, on the drivers side there's just a hole, i beleive that's the cause

Nice one guys- you've just saved me a lot of time!

This applies to the 182 I assume?

answered my question too! I always wondered what it was, mines a mk3 with the sensor, etc.

so if i bung the hole with some silicon or something would that stop the whistling/squealing?
