I am sad to report that I can emphasize with most of the reliability complaints listed at this site.
I've had other VW owners tell me the same thing happened to their antenna and oil pans.
After hearing a whining noise and seeing traces of oil from tailpipe, my mechanic said the turbo may need replacing, among other items. Estimate to replace turbo: $3300.
I have started shopping for another car, and it won't be a Volkswagen.
I'm not a mechanic, but I have read many reviews in which Passat owners have had to replace turbos. 2 things are crucial here. 1) Only use a good Synthetic motor oil here. (Mobil 1 preferably) The turbo motors almost require synthetic in order to preserve the life of the turbo. 2) Make sure you are doing regular oil changes (<3,000 miles) I know many manufacturers are saying 5,000 miles is fine, but unless you want to replace your turbo, use the proper oil, and change your oil at 3,000 miles, or even more often if you can afford to. My thoughts...
