Fuel System
Only use the grades of fuel recommended in the fuel
specification, see Technical Data page 131. Always
observe the greatest cleanliness during re-fuelling and
work on the fuel system.
All work on the unit injectors of the engine must be
carried out by an authorized workshop.
WARNING!
Fire hazard. When carrying out work on the fuel system
make sure the engine is cold. A fuel spill onto a hot
surface or an electrical component can cause a fire.
Store fuel soaked rags so that they cannot cause fire.
Engine Fuel Filter Replacement
1 Close the fuel tap(s).
2 Clean the filter bracket and place a suitable vessel
under the filter.
3 Undo the connector (1). Unscrew the filter; use a
filter wrench if necessary.
4 Clean the sealing surfaces on the filter holder.
Make sure that the filter is clean and that the seal
rings are undamaged. Moisten the seal rings with
engine oil.
IMPORTANT!
Do not fill the new filter with fuel before installation;
dirt may get into the system and cause damage and
malfunctions.
5 Screw on the new filter by hand until the gasket just
bottoms on the sealing surface, then tighten a fur-
ther 1/2 turn.
Replace the connector (1).
6 Open the fuel tap.
