Injectors, checking: Notes

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2001 Volkswagen Jetta, 2001 Volkswagen Golf, 2000 Volkswagen Jetta, 2000 Volkswagen Golf, and 1999 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.

This engine is equipped with dual spring injectors. The fuel injection therefore occurs in 2 stages. These injectors are to be exchanged if malfunctions occur as neither servicing nor pressure setting is possible.

Special tools, testers and auxiliary items required
