Advice to be followed before any operation
Protect the accessories and timing belts, the electrical accessories (starter, alternator, electric power assisted
steering pump) and the mating face to prevent diesel fuel spilling onto the clutch friction plate).
Check that you have plugs for the unions to be opened (set of plugs available from the Parts Department). The plugs
are single-use only. After use, they must be discarded (once used they are soiled and cleaning is not sufficient to
make them reusable). Unused plugs must be discarded.
Ensure that you have hermetically resealable plastic bags for storing removed parts. Parts stored in this way will be
less susceptible to the risk of contamination. These are single-use bags; after use they must be discarded.
Use lint-free cleaning cloths (part no. 77 11 211 707). Using normal cloth or paper is prohibited. They are not lint-free
and could contaminate the fuel circuit. Each cloth should only be used once.
Use fresh cleaning agent for each operation (used cleaning agent is contaminated). Pour it into an uncontaminated
container.
For each operation, use a clean brush in good condition (the brush must not shed its bristles).
Use a brush and cleaning agent to clean the unions to be opened.
Blow compressed air over the cleaned parts (the tools and workbench, as well as the parts, unions, and injection
system sections). Check that no bristles remain.
Wash your hands before and during the operation if necessary.
When wearing leather protective gloves cover them with latex gloves to prevent contamination.
Instructions to be followed during the operation
As soon as the circuit is open, all openings must be plugged to prevent impurities from entering the system.
The plugs to be used are available from the Parts Department. They must not be reused under any circumstances.
Close the hermetically sealed bag, even if it has to be reopened shortly afterwards. Ambient air carries impurities.
All components removed from the injection system must be stored in a hermetically sealed plastic bag once they
have been plugged.
Using a brush, cleaning agent, air gun, sponge or normal cloth is strictly prohibited once the circuit has been
opened. These items are likely to allow impurities to enter the system.
A new component replacing an old one must not be removed from its packaging until it is to be fitted to the vehicle.
