Installation Notes and Tips

Verify engine code and injector part number before installation.

Replace and lubricate the included O-rings as required during installation, and confirm proper sealing after startup. Bosch 62839 is used in Volkswagen Golf Alltrack, Golf SportWagen, Beetle, Jetta, and Passat applications where the injector location is listed as N/A in the catalog fitment data.
