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.
