1.1

Safety Precautions, Working on Fuel

Supply System

There Is a Risk of Injury Because the Fuel Is under High Pressure.
Fuel system is under high pressure. Injury from fuel squirting out

is possible.
– Release the fuel system before opening the fuel system.
Procedure for releasing the fuel high pressure. Refer to

⇒ “1.2 High Fuel Pressure, Reducing”, page 283

 .

Burn Risk Due to Escaping Fuel.
With the battery connected, the door contact switch activates the

fuel pump when opening the driver door. Escaped fuel can ignite

and lead to fire.
– Before opening the fuel system interruption the power supply

for the fuel pump.

1.2

Start/Stop System Safety Precautions

There Is a Risk of Injury from the Engine Starting Unexpectedly.
The engine can start unexpectedly for vehicles while the start/stop

system is activated. If the Start/Stop System is activated, is rec‐

ognized by a message in the instrument cluster.
– Deactivate the Start/Stop System: switch off the ignition.

1.3

Safety Precautions, Road Test with

Testing Equipment

There Is a Risk of Injury Due to Unsecured Testing Equipment.
If the front passenger airbag activates during an accident unse‐

cured testing equipment becomes a dangerous projectile.
– Secure testing equipment on the rear seat.
or
– Have a second person operate testing equipment on the rear

seat.

1.4

Ignition System Safety Precautions

There Is a Risk of Injury Due to Electric Shock.
With the engine running the ignition system is under high voltage.

Electric shock is possible through contact with the ignition system.
– Never touch or remove ignition wires when engine is running

or turning at starting speed.

Danger of Damaging the Components.
An engine wash as well as connecting and disconnecting electri‐

cal component wires with the engine running can cause damage.
– Switch off the ignition before connecting and disconnecting

wires.

– Switch off the ignition before an engine wash.

1.5

Cooling System Safety Precautions

There Is a Risk of Burns from Hot Coolant.
The coolant system is under pressure when the engine is warm.

Risk of scalding due to hot steam and hot coolant.
– Wear safety gloves.
– Wear protective eyewear.
– Reduce the pressure: cover the coolant reservoir cap with a

cloth and carefully open.

Identification

⇒ “2.1 Engine Number/Engine Characteristics”, page 3

2.1

Engine Number/Engine Characteristics

Engine Number
The engine number (“engine codes” and “serial number”) are lo‐

cated at the engine/transmission joint.
The engine code is also printed behind the oil filter on the cylinder

block.
There is also a label glued to the timing chain cover with the “en‐

gine code” and “serial number”.
The first three digits describe the mechanical structure of the en‐

gine and are still stamped on the engine. The fourth digit de‐

scribes the engine output and torque and depends on the engine

control module. Four-digit engine codes are found on the type

plate and vehicle data label. It can also be read via the Engine

Control Module (ECM).
