Hi, i have s4 t2 that make a squeal sound when I accelerate from a stop or shifting gears. It happens when the clutch starts engaging, pedal releasing. It happens when the rpm slows down to match the input shaft rpm.
I simulated the noise on a hoist and handbrake on while I accelerate in 1st gear.

 

Any clues? it is driving me crazy :P
Oh also makes the noise when I release the clutch when engine rpm is slower than input shaft. While the engine rpm climbs to match input shaft speed

 

does it happen when you rev the engine with the trans in neutral?

 

any metal in the trans fluid?

 

No, i,m starting to think its the clutch plate itself. act clutch
