Troopers, I've just completed Melbourne VIC to Cooktown QLD and back in my FG XR6T. Great drive. About half way there (with 7000 kn on the clock) the turbo started developing a slightly louder whistle, particularly just off idle. By the time I got back to Melbourne, it sounded just like the car in the Mad Max movie. So coool. The car wasn't losing power or smoking, just a louder turbo whistle. At it's 15,000 km service a new turbo was whipped in. I was told "the engineers wanted to look at it" - as if that will help. Anyone had or heard of similar issues
