In owners' own words
Purchased a used 2004 VW Passat in april 09. Did not purchase an extended warranty for the vehicle, however, such would not have covered this issue regardless.
Sludge buildup cause by VW design flaw LED to engine locking ... VW refusing to cover engine replacement even though covered by power train warranty.
A potential issue has come to my attention that some engine parts related to the balance shaft assembly and the engine oil pump system drive can fail as early as 45,000 miles.

Recalls for the 2004 Volkswagen Passat: 4
These service replacement parts were sold for use in model year 1999-2005 Audi A4, 2000-2006 Audi TT, 1998-2005 Volkswagen Beetle, 1999-2006 Golf, 1999-2008 and 2011-2013 Volkswagen Jetta, and 2000-2005 Volkswagen Passat. A failure of the timing belt may cause the engine to shut down, potentially increasing the risk of a vehicle crash.
These vehicles may have an underbody heat shield that can become damaged. In addition, affected vehicles with automatic or manual transmissions may have a fuel line (1.8T engines only) or fuel tank ventilation valve (4MOTION/ALL wheel drive only) that can leak due to fracture. A heat shield that may contact the exhaust system can result in a vehicle fire. In addition, a fuel leak from a fuel line or fuel tank ventilation valve, in the presence of an ignition source, can lead to a vehicle fire.
On certain passenger, wagon, and convertible vehicles equipped with or without cruise control, a brake light switch may malfunction if it was installed incorrectly. The brake lights could become inoperative, or remain on. Failure to provide the proper signal when braking could lead to a crash without warning.
On certain passenger vehicles, the high pressure diesel pumps were produced with an improper fastener, which could allow diesel fuel to escape from the pump. Fuel leakage in the presence of an ignition source may lead to a fire.
