i know that the throw out bearing on the clutch is on the way out, but last night i heard the weirdest noise coming my the 7M, i was just driving along the main road when a loud knocking/scratching noise was coming from the engine, i lifted up the bonnet and the noise sounds like its coming from near the turbo or the exhaust side of the engine ?!??! any ideas ? i did it a little bit this morning but thats it.. the car runs fine tho, i revved it a little harder when it was making that noise but it was quite present, when i came to a stand still and te turbo timer ran it dissapeared.. i have never heard it before.. very strange... any ideas ?
