1.1 Safety precautions when working on fuel supply system
Risk of injury due to highly-pressurised fuel.
The fuel system is pressurised. Injury possible due to fuel which
may spurt out.
Before opening the fuel system:
– Wear safety goggles.
– Wear protection gloves.
– Release pressure: place clean cloth around connection and
carefully open connection.
Risk of fire due to escaping fuel
If the battery is connected, the door contact switch will activate
the fuel pump when the door is opened. Escaping fuel may ignite
and cause a fire.
– Disconnect the fuel pump from the power supply before open‐
ing the fuel system.
1.2 Safety precautions for working on vehicles with start-stop system.
Risk of injury due to unexpected engine start-up
In the case of vehicles with activated Start/Stop system, the en‐
gine may start up unexpectedly. The status of the Start/Stop
system is indicated by a message in the dash panel insert.
– Deactivate Start/Stop system by switching off the ignition.

1.3 Safety precautions during road tests in which testing and measuring equip‐
ment is used
Risk of injury due to unsecured test and measuring equipment.
If the front passenger airbag deploys in the event of an accident,
the test and measuring devices being tossed around become
hazardous projectiles.
– Secure the test and measuring devices on the rear seat using
a seat belt.
or
– A second person should operate the test and measuring de‐
vices on the rear seat.
1.4 Safety precautions when working on ignition system
Risk of injury due to electric shock
The ignition system is under high-voltage when the engine is run‐
ning. Touching the ignition system may result in an electric shock.
– Do not touch or disconnect ignition cables when the engine is
running or being turned at starter speed.
Risk of damage to components
If the engine is washed while running and if electric cables are
connected or disconnected, components may become damaged.
– Switch off the ignition before connecting or disconnecting elec‐
tric cables.
– Also, switch off the ignition before washing the engine.
1.5 Safety precautions when working on the cooling system
Risk of scalding by hot coolant
The cooling system is under pressure when the engine is hot. Hot
steam/hot coolant can escape - risk of scalding.
– Wear protection gloves.
– Wear safety goggles.
– Reduce excess pressure by covering cap of coolant expan‐
sion tank with cloths and opening it carefully.

1.6 Safety precautions when working on ex‐
haust system
CAUTION
Risk of poisoning due to chemical substances
Exhaust gas temperature senders may contain chemical sub‐
stances. There is a risk of poisoning or injuries to respiratory
system.
– Never open an exhaust gas temperature sender by cutting,
sawing or any other means.
CAUTION
Risk of injury due to hot condensate and particles in the exhaust
system.
The exhaust system could contain hot condensate and/or par‐
ticles. There is a risk of injury to the eyes, skin and respiratory
system, as well as poisoning.
– Always wear protective gloves and eye protection when cut‐
ting the exhaust system.
– When cutting, use an extraction system or otherwise ensure
sufficient ventilation.
There is a danger of the damper element becoming damaged.
Do not allow the decoupling element to kink by more than 10°.
Do not subject the decoupling element to tensile force.
Do not damage wire mesh on decoupling element.

2.1 Engine identification number/engine da‐
ta
Engine number
The engine code is also stamped on the cylinder block behind the
oil filter.
In addition, there is a sticker on the right of the timing chain cover
with “engine code” and “serial number”.
The first 3 digits denote the mechanical design of the engine and
are stamped on the engine. The fourth digit shows the engine
output and torque and varies according to engine control unit. The
four-character engine code can be found on the identification
plate as well as on the vehicle data sticker. It can also be read
from the engine control unit.

3.1 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

connected. Where necessary, make sketches or take photo‐
graphs.
♦ To prevent damaging pipes, hoses and wiring, ensure suffi‐
cient clearance from all moving or hot components in engine
compartment (little space in engine compartment).
3.5 Installing radiators and condensers
Even if installed correctly, the radiator, the condenser and the
charge air cooler may have small dents in their fins. This does not
mean that the components are damaged. It is not permissible to
renew radiators, charge air coolers or condensers only because
of such minor dents.
3.6 Vacuum system: checking
Special tools and workshop equipment required
♦ Hand vacuum pump - VAS 6213-
Operation process
– Check all vacuum lines in the complete vacuum system for:
♦ Cracks
♦ Traces of animal bites
♦ Kinked or crushed lines
♦ Lines porous or leaking
– Check vacuum line to solenoid valve and from solenoid valve
to corresponding component.
– If a fault is stored in the event memory, check all vacuum lines
leading to the corresponding component, and also check the
remaining vacuum lines leading to other components.
– If it is not possible to build up pressure with the hand vacuum
pump - VAS 6213- or if the pressure drops again immediately,
check the hand vacuum pump and connecting hoses for leaks.

♦ Protective glasses
♦ Protective gloves
♦ Double ladder
Removing
Note
♦ The engine is removed downwards with gearbox. To do this,
the subframe needs to be removed.
♦ After removing of coolant or fuel lines, these must be sealed
using the engine sealing cap set - VAS 6122- to prevent dirt
from entering or coolant or fuel from running out.
♦ Fit cable ties in the original positions when installing.
♦ All cable ties which are opened or cut through when engine is
removed must be replaced in the same position when engine
is installed.
CAUTION
On a warm motor, the cooling system is under high pressure.
Hot steam/hot coolant can escape - risk of scalding.
Risk of scalding to skin and body parts.
– Wear protection gloves.
– Wear safety goggles.
– Reduce excess pressure by covering cap of coolant expan‐
sion tank with cloths and opening it carefully.
