The owners manual in my '03 Jetta TDI indicates CHECK timing belt every 20K and CHANGE it at 100K. Its a manual. The '03 is the last of the ALH engine, supposed to be the best. I have a friend with an '05 Jetta TDI wagon, manual shift. Its a PD engine and averages 47.8mpg. The Passat with the PD engine gets less mpg's that earlier ALH engines simply because its bigger, heavier and automatic.
