    Default Scraping/scratching noise

    Went out for a run last night, and noticed people looking at my signum as I went by them. Now this isn't unusual as most people say " whats that? " to me... but this was different... I turned down the tunes I had blarring inside only to hear a weird scraping/scratching noise coming from the engine.. when decelleratiing... F me... never hearanything like it before.., So I'm thinking is it the turbo?...I stopped the car, revved it a little and it still did it. the turbo is definitely spinning, so could it be the wastegate? not sure, or is the turbo coming to the end of its life?.. It's not doing it all the time though. There's no loss in power though, or could it be something completely different? do collapsed bearings make these sort of noises?

    Any thoughts/ suggestions please as I've got a 800 mile journey this week

    Scraping/scratching or squeeling may indicate an idler pulley bearing or alternator bearing problem.
