Don't wait for it to fail change the turbo use good oil preferably synthetic (due to high heat), on older Volvos it was important to change the oil feed line to the turbo if there was a failing turbo. Many good aftermarket turbo rebuilding companies out there that offer good rebuilt units. Try looking at or a website like "turbocity", don't know exact address for them I think they are in Los Angelas or Texas.
