Just noticed it too day, normally the supercharger makes a nice whining noise. However its now switched to an irritating high pitched "wake the dead" whistle noise. Any one got any idea what this is and what might be the cause. I may have to take it in to the dealer as its really frying my nerves and can be heard over the stereo!

Do you have any sort of aftermarket CAI on there? They tend to whistle.

Could be a leaky gasket/seal. Worth seeing the dealer about, probably sooner rather than later.

Punctured hose ?
Paul has given the best advice, go see the dealer.

many thanks for the advice. ive checked the hoses cant see anything odd. whistling only occurs after a 10 mins and then eventually goes away. fluid levels arent dropping at all.

no aftermarket mods..

Generally excessive whistling means there's air leaking in somewhere, so I'd certainly get the dealer to take a good look.

shes going into the dealer this afternoon. for a checkup, fingers crossed and all that.. thanks for the advice guys.

verdict. a clip was loose on a hose. something to do with redirecting harmful gases back to the exhaust system. from an untrained eye it looke ok. mechanic found it immediately and reclipped it on. It explained the intermittent nature of the fault as it apparently only vents at certain revs / pressure etc. a very lucky find..

Sounded like it was leaky gasses or air somehow, seems to be a good spot by the dealer.

sounds like the good old PCV valve....
