Well I have another issue after the engine replacement a few weeks back.....my turbo (i assume) squeals when engine is running, seems to be when I give it about 50% pedal and it squeals from 2,000rpm to 3,500 to about 4,000rpm.

It's not a normal noise as its didn't do it before the engine replacement so if anyone has any ideas I'd be keen to hear them. I'm sick of taking it back to the garage at the moment.

I'm a Skoda mechanic... I can't hear anything.. bye bye approach.
