Radiators don't fail at 2 years old, and even VWA recognized that.
Apparently these ones do. My 2000 Passat had its rad replaced last year. The very experienced mechanic who did the work said he's seen the same kinds of failures in Audis with the same design of rad -- plastic tanks on the ends with metal tubes in the middle. FWIW, he felt they were all manufacturing defects because of the problem of mating plastic to metal. Mine was leaking, but only when the engine was hot -- when the plastic and metal expanded different amounts. The leak was very obviously right where plastic and metal met.
