Hi guys got a feeling my turbo on its way out when iam accelerating I can hear whinning noise when I ease off it goes off or when iam changing gear !!! Won't make noise when idling !!! Any ideas what I can check , thanks

 

If you are sure it's a rubbing type noise have it checked out.
If it has a loose connection anywhere in the air movement system piping it can make whistling or high pitched noises. Check all the hose and piping clamps to make sure all are tight.
