Injectors, checking: Notes

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2006 Volkswagen Golf, 2005 Volkswagen Jetta, 2005 Volkswagen Golf, 2004 Volkswagen Jetta, and 2004 Volkswagen Golf. 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
