    Buzzing from Engine (Drivers Side)

    I'm still getting a cross between a hissing and buzzing noise from under the bonnet of the car.

    I've located it to the area between the airbox and the engine. It sounds loudest from the front drivers side wheel arch and it's only when the car's warmed up it makes the noise. It also seems to fall and rise with the revs.

    What's down there that could make such a noise?

    Alternator
    Aircon Compressor
    Water Pump

    Cheers

    It's only doing it when the car's warmed up so I'd have thought if it was a boost leak then it would be doing it all the time.

    I've booked it into Vauxhall for next Wednesday as I haven't got the time, patience or knowledge to be able to diagnose and fix it myself.

    It sounds like a buzzing fridge type noise which can also be similar to the noise an old spinning hard drive makes.

    Cheers
