3.1
Clean Working Conditions
When working on the fuel supply/injection system, pay careful at‐
tention to the following “5 rules” of cleanliness:
♦ Thoroughly clean the connecting points and the surrounding
area before loosening.
♦ Place the removed parts on a clean surface and cover them.
Only use lint-free cloths!
♦ Carefully cover or seal opened components if the repair will
not be done immediately.
♦ Install only clean parts: remove the replacement parts from
their packaging just before installing them. Do not use parts
that have been stored loose (for example, in tool boxes etc.).
♦ If the system is open: do not work with compressed air. Do not
move vehicle.
♦ Make sure no fuel gets onto the fuel hoses. If necessary, wipe
off the fuel hoses immediately.
♦ Protect any disconnected connectors from dirt and moisture
and connect them only when they are completely dry.
3.2
Engine Contaminants
Special tools and workshop equipment required
♦ Engine Bung Set - VAS6122-
♦ To prevent foreign objects from entering when working on the
engine, seal open intake and exhaust channels with suitable
plugs, for example from the Engine Bung Set - VAS6122- .
3.3
Contact Corrosion
Contact corrosion can occur if incorrect fasteners (bolts, nuts,
washers, etc.) are used.
For this reason, only fasteners with a special surface coating are
installed.
In addition, rubber or plastic parts and adhesives are made of
non-conductive materials.
If there are doubts about whether the parts are suitable, then use
new parts. Refer to the Parts Catalog.
3.4
Wire Routing and Securing
♦ Mark the individual fuel, hydraulic and vacuum lines, the EVAP
system lines or the electrical wires before disconnecting and/
or removing them. This will prevent a mix-up when reconnect‐
ing them and will ensure the original installation location is
kept.
♦ If necessary, draw sketches or take pictures.
♦ Due to the limited space inside the engine compartment, be
especially careful when working near moving or hot parts to
avoid damaging the lines.
3.5
Cooler and Condenser Assembly
When assembled correctly, the radiator, condenser and turbo‐
charger may have slight impressions on their fins. It is not dam‐
age. Do no replace the cooler, condenser or turbocharger
because of impressions like that.
3.6
Vacuum System, Checking
Special tools and workshop equipment required
♦ Hand Vacuum Pump - VAS6213-
Procedure
– Check all vacuum lines in the vacuum system for:
♦ Cracks
♦ Damage caused by animals
♦ Crimps
♦ Leaks
– Check the vacuum lines leading both to and from the solenoid
valve to the respective component.
– If there is a fault, check all the vacuum lines for the named
component, but also all the vacuum lines to the other compo‐
nents.
– If using the Hand Vacuum Pump - VAS6213- does not produce
any pressure or if the pressure drops again right away, then
check the hand vacuum pump and the connection hoses for
leaks.
