Cleaning rules

Even slight soiling can cause faults. Following the following rules
for cleanliness when working on the fuel supply system and in‐
jection system or on the turbocharger:
♦ Carefully clean connection points and the surrounding area
with engine cleaner or brake cleaner and dry thoroughly before
opening.
♦ Seal off open pipes/lines and connections immediately with
clean plugs, e.g. from engine sealing cap set - VAS 6122- .
♦ Place removed parts on a clean surface. Cover with lint-free
cloths only.

♦ Carefully cover opened components or seal them if repairs
cannot be carried out immediately.
♦ Only install clean components: Only unpack replacement
parts immediately prior to installation. Do not fit parts that have
been stored unpackaged (e.g. in tool boxes etc.).
♦ When the system is open, avoid working with compressed air
and moving vehicle.
♦ Make sure that no fuel runs onto the fuel hoses. Should this
occur, the fuel hoses must be cleaned again immediately.
♦ Protect disconnected electrical connectors from dirt and water,
and reconnect them only when dry.
3.2

Foreign particles in engine

♦ Before working on the engine, all open inlet and exhaust ports
must be sealed with suitable plugs (from engine bung set -
VAS 6122- ) to prevent foreign particles from entering the
engine.
3.3

Contact corrosion

Contact corrosion can occur if unsuitable fasteners are used (e.g.
bolts, nuts, washers, etc.).
For this reason, only fasteners with a special surface coating are
installed in the vehicle.
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 pipes, hoses
and wiring
♦ Mark fuel lines, vacuum lines, pipes/hoses for activated char‐
coal filter system and electrical wiring etc. before removal so
they can be re-installed in the original positions and correctly
