X3 3.0i M54 Engine Noise

Hi guys,

Wondered if I might be able to ask some opinions. My 3.0i X3 has developed an extremely irritating noise coming from the engine (M54). The noise is most significant when the car is in 'Drive' but stationary, once I shift it to 'Park' the noise reduces but remains on a more sporadic basis. Once I accelerate/drive the noise disappears and only reoccurs when I stop at lights etc.

I thought this might be something familiar to guys on here with the same engine. I'm working on an assumption that it's something tensioner/pulley related, but this is just a hunch.



Any input is welcome.

Thanks :thumbsup:
