Hello all,

A loud whistling kind of noise upon accelerating has just started. It isn't there when idling and it stops when the accelerator peddle is released.

We noticed this on the first long drive out since the car had it's EGR valve and also and oxygen sensor replaced (which was a pretty expensive repair!). I would say it was only about 200 to 300 km after the repair (done just before Christmas).

The car has done about 120k km overall. It had it's timing belt and water pump replacement at about 110k km.

Any ideas what this could be, before taking it to the mechanic? I'd like to have some idea before just blindly accepting what they say and potentially forking out hundreds of dollars more.

Thanks.

I'd say boost leak based on that description.  This should also throw a EPC light and code if it's enough of a leak.  So start by checking all of the intake path between the turbo and the manifold.

Thanks, I took it to a mechanic and he checked all the hoses and things to do with the turbo and all good. No leaks, no faulty valves or whatever (can you tell I am not mechanically literate?) Reckons it's just the noise the turbo makes now and nothing to worry about.
