Gents! I know only about enough to be dangerous!
My 2006 Navara (I assume D40) has always made a modest turbo whine (especially when cold) when accelerating but it's got quite a bit louder recently. The truck is still running well. When revved hard there is quite a lot of black carbon coming...
Hi. Is the turbo still working okay? I've got exactly the same whining siren noise, without the metallic noise yet. Did you buy new or refurb turbo? Can you suggest a good supplier?
