Replacing the injector (VW Golf 2)

Checking and repairing the injector must be done at service stations. These works cannot be done independently, since, in addition to the need to use special equipment, certain safety regulations must be followed.



To detect a faulty injector, disconnect the injector lines one by one and start the engine. If the engine does not change the sound of operation after disconnecting this line, then this injector is faulty. To remove the injector, disconnect the line and use a 27 mm wrench to unscrew the injector. When assembling, install a new heat-dissipating washer and insert it so that the concave side is directed towards the injector. The injector body is tightened with a torque of 70 Nm, and the line - 25 Nm. If you only need to replace the sprayer, you can disassemble the injector. These operations must be carried out in conditions of maximum cleanliness. Secure the injector body in a vice and loosen the body nut (figure 257). Then secure the housing nut in a vice and remove the parts shown in Figure 258 one by one.

Insert the new nozzle in the reverse order and tighten the housing nut to 70 Nm. To do this, the housing must be clamped in a vice again.
