Mitsubishi Outlander turbo whine

When I start my Mitsubishi Outlander from cold I get a whining noise that increases on acceleration and decreases when I slow down. It sounds like wind whistling through the trees. After 2/3 miles it stops. I think it may be a turbo whine. The manufacturer's guarantee runs out next year. Does this sound like a problem to you and should the supplying garage be informed?

Yes, it is almost certainly turbo whine. Might be because the turbo bearing is not getting enough oil and, if so, that will be because the turbo bearing oil feed and oil return pipes are partly blocked with carbon from the engine having been switched off too many times when the turbo was too hot. Should have been idled for a minute or two.
