Had a quick look if this had been posted before but couldn't see anything so here we go.

Basically what happened was driving home from work yesterday and had zero drama until about 10km from home. When I turned a corner off tonkin highway onto Thomas road and as I shifted down to 3rd to take the corner my turbo started making a strange squeal when I gave it a bit coming out of the turn. Happens now only shifting from 2nd through til 4th. I pulled over almost instantly and checked fluids and everything's fine apart from my oil being a little black so going to do a change this weekend.

Anybody else had this issue or know what might be wrong?

Sounds like this video but a fair bit worse than that.
