Driving my Passat turbo diesel on I-81 noted a loss in power; drove the car home (about another 3 miles) and noted a strange humming sound from under the hood. Next day the sound was still there, with a blinking glow plug light and the engine light was on. Spoke with dealer and car was towed in; two weeks later the car was back with a new turbo in it.
