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.
