Default Question...

With ESP off, and speed shifting into 2nd and 3rd I can hear a very high pitched screatch and it's not the tires.

What concerns me is that it is either the clutch or my BPV's are stuck closed and my turbo's are screaming from the boost.

Anybody else experience this?

Default Yes...but

I really think its the valves...not the turbos. They have a very DISTINCT sound.

probably either the bpv's yelping, or the other dump valve opening.

It's your synchros probably. You did say you were speeding shifting. I wouldn't do that in the S4.

I'm not a techie, but can the DBW system really handle speedshifts?

Torsen does not make any sound, EDL is noisy, but not a high pitched sound.
