Scraping noise under acceleration (n53 e92)

David I. · 06-13-2023, 09:36 AM

Hey guys. I just bought a 330i 6mt, and i can hear a scraping noise coming from the front when i have my windows down. I was hoping you guys could come with some ideas as to what it could be?

Its only when moving, and under acceleration. Cant hear anything when rolling in neutral. Typically around 1500-2500 rpm. Its more prevalent on the right front.

Also, i feel like its only happening when the engine is under decent load, like acceleration or going up a hill. Perhaps this could explain why i dont hear anything in neutral?

Anyways, im thinking gearbox or clutch. But im sure some of you know these cars much better then me, since i've driven diesels all my life.

Thank you

Could it be pinking (also known as knocking)?
