Complete Bosch injector for all rotary pump TDI models, including all A3 Jetta TDI 97-99, all B4 Passat TDI 96-97 and 1999-2003 MkIV Jetta, Golf and New Beetle TDI with engine code ALH (incl. '98 New Beetle TDI).

This is the #3 injector with the needle-lift sensor. This injector will not work for cylinders 1, 2 or 4.

This injector comes with a .154 nozzle originally equipped on ALH automatic models.  Injectors must have matching nozzles, so manual transmission cars will require a nozzle swap to use this injector.  For manual transmission TDIs we recommend upgrading to the Bosio Sprint 520 nozzle for all 4 injectors.
