Known issues on the 2003 TT. One recall is on federal record for this model year, covering an aftermarket Tru-Flow water pump: a failure of the timing belt driven off a defective pump can cause the engine to shut down, potentially increasing the risk of a crash. Owners have filed 18 complaints for the year. The factory diagnostic and repair procedures behind that system are here.

Whether you're inspecting the timing belt and water pump drive or working through a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 2003 TT.
