New to the forum and new to Audis. Can't tell if it's the clutch or the transmission. It mainly does this in first gear. The sound it makes is hard to describe, once out of first it's mainly gone. It kinda sounds like a go kart whining out (I know, dumb comparison but hard to describe) And another thing, don't know if it's connected. When idling, up in the engine compartment I can hear what sounds like a paper ball in a tin can blowing around. It does do it louder when revving it up a bit. Any knowledge would be greatly appreciated! Thanks! I forgot to mention, it's an 04 A6 1.8t quattro with a 6-speed

 

Anyone?

 

U spun a bearing do to over reving or faulty oil pump starving the engine oil or ur oil was too thin use 5w40 in the future but for now buy an engine it just happened to me n I bought an engine cause u eithe damaged the crankshaft/pistons scrape/rods or worst if u try go drive it will soon loose compression n shut off I can send u pic for facts I'm replacing as we speak
