so this car has had this noise since about 60k miles or earlier. i'm now at 148k and it's no worse. what is it, throw out bearing?

only happens on hard downshifts w/out matching revs. i always match revs so it's not a huge deal. but it also now happens in first upon letting the clutch out when it's cool out.

vid is of 3rd to 2nd gear downshift now rev matching.

Check your bypass valve. Sounds blown.

Are you sure that's not the BPV (with failed diaphram)?

it's a mechanical noise and there is some associated vibration.

I think it was the throw out bearing. The sound went away when I replaced the clutch and bearing. <a href="https://forums.audiworld.com/s4s6/msgs/83821.phtml">It might have been the clutch itself though</a>.
