    VXR goes 'twang' when I pull off from "cold"

    Hey All,

    What in my engine goes 'twang' when I pull off for the first time after the car has been standing a while? It sounds a little like when you lock the doors from inside, but the sound comes from the engine bay.

    Apart from this sound there's nothing else wrong with the car, I think it's always done it - I've had the car a week (2007 plate).

    Any help or ideas would be appreciated, this is a new engine to me.

    Thanks!

    I always thought this was one of the suspension springs twanging, (owned a 1.8 16v convertible for a few years), you learn something new every day!
