The Jetta TDI A4, or MkIV Jetta, was known as the Bora in most places outside of North America. Like the previous generation Jetta, it shares its platform with the Golf, in this case the MkIV Golf, or Golf A4.
In the model years of 19995. to 2003 the Jetta TDI was powered by a 1.9 liter turbocharged direct injection diesel.
Engine Specifications:
- Engine Code: ALH
- Horsepower: 90 @ 3800 RPM
- Torque: 157 lb/ft @1950 RPM
- Injection Pump Type: Rotary
The early years of the ALH engine used a timing belt that was rated for 60,000 miles. An update in 2002 pushed the change interval to 80,000 miles. Finally, in 2003 the interval was pushed to 100,000, though there is some debate as to if the components themselves, rather than the belt, can be used for that long reliably.
