Turbo whistle

+1 on exhaust manifold.

Problem has been diagnosed and it is a crack in the egr pipe where it joins to the flange.Thanks for replies.

Thats a nice fix as opposed to intercooler or similar.

Thought I'd let everyone know that upon further investigation it turns out that it was actually the exhaust manifold gasket which caused the whistle.Fitted new egr pipe anyway.Mechanic inspected turbo and was happy that it is in top nick.Looking forward to Plenty Hwy and Great central to Perth next year.

Good to know as a reference.
Enjoy!

Mine did the same not long ago little sound big job

Yea mine warped and need machining the whistle is so annoying
