VVT Solenoid?

I guess you have the 1.6 16v VVT petrol engine?

Maybe it's like mine, that a few times, made a buzz which sounds like yours. It turned out to be the VVT Solenoid which is on the top of the engine, near the top mounting. It buzzed a few times when i had rough running problems and the engine was off and locked. Finally turned out to be the Camshaft Position Sensor faulty. Never happened again after i replaced this sensor.

But, maybe its not this. Is it a 'buzzing' sound or a faint tone - like the alarm but quiter? Does yours have an alarm? If i lock my Megane II with the bonnet slightly open (or a door left open) then the indicators don't flash when i lock the doors and for about a minute after you can hear a faint tone type noise from under the bonnet somewhere?

Maybe one of these?
