Hi All,
Lately I'm getting a strange noise whenever I accelerate even slightly. First I thought of it as a hiss, like a pressure leak or something, but now I would describe it more like a whoosh, kind of like the wind noise you get when driving with a roof rack on, if that makes any sense. Sometimes it also sounds like a fan or rotor spinning.
Sitting in the driver's seat it sounds as if it's coming from the passenger side of the engine bay, but I could be wrong. I've opened the bonnet and tried to listen while someone else revs the engine in neutral, but I couldn't hear the noise at all.
It doesn't seem to correlate with revs or speed, as such, although it does seem more noticeable when driving at low speeds (or perhaps that's just when it's more audible).
There are no warning lights/messages on, and the car behaves otherwise normally.
Anyone have any ideas what might be causing this? Could it be early signs of a turbo failure? (I gather this particular engine has a bi-turbo configuration.) If so, is there an easy way to make sure, or does the turbo need to be opened up?
Cheers,
robaa
