Water separator - drain
Water reduces the lubrication capacity of the diesel fuel. The injection pump could be damaged and metal parts
could corrode. Furthermore, the diesel particle filter's cleaning interval can no longer be guaranteed. The particle
filter would be clogged earlier than expected. If the "Water mixed with fuel" malfunction indicator appears on the
display, the water must be drained from the water separator immediately after the engine has stopped.
Open the engine compartment cover (page 154).
Visual inspection of the water separator for water and sedi-
ments.
Turn the cock (2) to the “OFF” position.
Loosen the venting screw (3).
Loosen the drain valve (6) and drain the impurities.
Close the drain valve.
Tighten the venting screw.
Make sure that the sensor cable plug (5) is connected.
Switch the shutoff-valve to the ON position.
Bleed the fuel system (page 149).
Check the water separator for leaks.
Close the engine compartment cover.
Water and impurities in the fuel settle in the water sep-
arator. The water separator is equipped with a sensor
that checks the fill level. If any such deposits form, a
message will appear on the display as shown in figure
on the right.
Risk of engine damages from water in the fuel!
Always remove spilled fuel immediately.
Place a cleaning cloth under the water separator (1) to
prevent fuel from running onto the ground.
Dispose of cleaning cloths according to the applicable environmental protection regulations.
