Hi. I've been searching for information regarding a screeching sound on Mondeo st tdci under acceleration. The sounds starts at 2500 rpm which indicates to me to be turbo related.

I've checked the EGR to intercooler pipe which seemed week so replaced with a known good one. The car has recently had a new EGR fitted.
Boost doesn't seem to be down that much.
I've taken the pipe off the turbo to check for play but all seems good.

Does anybody have any ideas where to look?

Thank you
