Diesel engines other than supercharged
VW PASSAT diesel engines are equipped with a cold start aid. Using the drive rod, the injection advance piston in the high pressure fuel pump is moved in the injection advance direction by approximately 2.5°. This improves cold engine starting. During repair work, the drive rod must be connected as follows:
Move puck (1) drive tension. Push the drive rod through the rubber bushing in the counter-support at the injection pump. At the same time, insert the traction wire into the support pin (3).
Insert retaining clip (2).
Move the lever to the position «ABOUT», for which the lever is pushed all the way in the direction of the arrow.
Pull the traction wire tightly and secure with a locking bolt (3).
