If your oil is low enough (approx 2 qts), add 2 qts of Hot Shot Secret Stiction Eliminator. 60 bucks or so and $$ back guarantee. Worth a shot and a lot cheaper than a new turbo.

As you know, oil flows thru the turbo and the vanes pivot inside the turbo in some fashion. Anyways, the oil can get burnt onto the inside of the turbo and pivot points and that's what's called "Stiction". The HSS has ingredients in it that will clean off the burnt oil and return things pretty much back to orig cond if not all the way. Another result of that it's working is after you put it in, start engine and run it, you'll see white smoke out of the tail pipe. Doesn't last forever.
Lot cheaper than a new/re-man turbo and labor. If it doesn't work, can always get your $$ back.
Ah, OK. I didn't know engine oil touched the vanes, I thought it was just the turbo shaft that was oil lubed. I thought the vanes were electrically actuated, not oil driven. On edit: looks like I'm right
