2.0 TSI Timing Belt
The VW 2-liter BPY-designated engine was widely used in mid-2000 model year cars, including the Passat, Eos, Jetta, Rabbit, and Rabbit/GTI. It is a well-constructed dual overhead cam gasoline powerplant that can deliver excellent power, economy* and reliability. Like all overhead cam engines in which the camshafts are belt-driven, the timing belt requires routine replacement as part of scheduled maintenance. The BPY engine uses a single camshaft timing belt sprocket to power both camshafts via a connecting chain between the camshafts. This 2.0L is an interference engine, which means that pistons and valves can meet in a most uncomfortable fashion if the timing belt should break. On the BPY engine the belt should be checked at 60,000 miles and replaced if it’s questionable. And it should be replaced at 100,000 miles in any event. There are two belts on these engines, a serpentine accessory drive belt that VW refers to as a ribbed belt (for obvious reasons…) and a toothed belt, which is the timing belt that keeps the camshafts and valves in happy coordination. The earliest configurations of this engine family used a one-piece belt guard for the toothed timing belt, and this design requires a bit more work than the later design, introduced in 2006, which used a two-piece guard, making access faster and easier. We’ll deal with that one first, since it is the more common design, and then we’ll come back and recap the additional steps needed when dealing with the single-piece design.
