Caution
The high-pressure pump has very close tolerances and must
not be allowed to run without fuel. To prevent this and to enable
the engine to start quickly after parts have been renewed, it is
important to observe the following:
♦ If components of the fuel system between the fuel tank
and the high-pressure pump have been removed or re‐
newed, the fuel system must be filled and bled before the
engine is started for the first time.
Bleeding fuel system
• There must be sufficient fuel in the tank.
– Activate fuel pump ⇒ Vehicle diagnostic tester.
– After the fuel system has been bled, start engine.
– Allow engine to run for several minutes at mid revs, then switch
engine off again.
– Read event memory and erase if necessary.
– Carry out a leakage test of the fuel system.
