1.7 Assembly overview - fuel system
WARNING
◆ Always read rules for cleanliness and instructions for
working on fuel system
◆ Always follow these rules for cleanliness and instruc-
tions before starting work and while working on the
fuel system.
To prevent the high-pressure fuel pump from running while
it is empty and to ensure that the engine starts quickly after
parts have been renewed, it is important to observe the fol-
lowing:
◆ If components of the fuel system between the fuel tank and
the high-pressure fuel pump are removed or renewed, the
fuel pump must be activated via a final control diagnosis to
bleed the fuel system.
◆ If a fuel pump, fuel line or the fuel filter is removed or re-
newed, the fuel pump must be activated via the final control
diagnosis for at least 60 seconds before the engine is star-
ted for the first time.
◆ If the high-pressure fuel pump is removed or renewed, the
fuel pump must be activated via the final control diagnosis
for at least 180 seconds before the engine is started for the
first time.
Caution
Adhere strictly to rules of cleanliness. No dirt must be al-
lowed to get into the disconnected fuel return lines or the
open connections on the injectors under any circumstan-
ces.
Protect open fuel connections from dirt entrainment using
suitable methods under all circumstances.
