3.1 Rules for cleanliness
When working on fuel supply and injection system, pay careful
attention to the following “rules” for cleanliness:
♦ Thoroughly clean all joints and surrounding areas before dis‐
mantling.
♦ Place removed parts on a clean surface and cover them over.
Use lint-free cloths only.
♦ Carefully cover opened components or seal them if repairs
cannot be carried out immediately.
♦ Install only clean parts; do not remove new parts from pack‐
aging until immediately before installing. Do not use parts that
have been kept unpackaged (for example in toolboxes).
♦ If system is open, do not work with compressed air. Do not
move the vehicle.
♦ Make sure that no fuel gets onto the fuel hoses. Should this
occur, the fuel hoses must be cleaned immediately.
♦ Protect disconnected electrical connectors from dirt and water,
and reconnect them only when dry.
3.2 Foreign objects in engine
To prevent the ingress of foreign bodies during work on the en‐
gine, seal open channels of the intake section and exhaust sec‐
tion with suitable bungs, for example from the engine bung set -
VAS 6122- .
3.3 Contact corrosion
Contact corrosion can occur if non-approved fasteners are used
on the vehicle (bolts, nuts, washers etc.).
For this reason, only connecting elements with a special surface
coating have been fitted.
Furthermore, rubber and plastic components as well as adhe‐
sives are made of non-conductive materials.
If there is any doubt about the suitability of parts, a general rule
is to use new parts ⇒ Electronic Parts Catalogue .
3.4 Routing and attachment of lines
♦ To prevent interchanging and to maintain the original installa‐
tion position, mark the fuel, hydraulic system, vacuum and
ACF system pipes or any wiring for example prior to removal.
Make sketches or take photographs if necessary.
♦ To avoid damaging pipes and wires, ensure adequate clear‐
ance from all moving or hot components in the engine com‐
partment on account of the confined space.
