1.1 Safety regulations for working on fuel supply
Risk of injury from highly pressurised fuel.
The fuel system is pressurised. Injury possible due to fuel which
may spurt out.
Before opening the fuel system:
– Wear protective goggles.
– Wear protective gloves.
– To release pressure, wrap a clean cloth around the connec‐
tion and carefully loosen the connection.
Danger of fire caused by escaping fuel
When the battery is connected and the driver door opens, the
door contact switch activates the fuel pump. Escaping fuel can
ignite and cause a fire.
– Disconnect voltage supply to fuel pump before opening the
fuel system.
1.2 Safety measures when working on vehicles with start/stop system
Risk of injury from motor starting unexpectedly
If the vehicle’s start/stop system is activated, the engine can
start unexpectedly. A message in the dash panel insert indi‐
cates whether the start/stop system is activated.
– Deactivate start/stop system by switching off the ignition.

1.3 Safety precautions when using testers and measuring instruments during
a road test
There is a risk of injury due to unsafe test and measuring equip‐
ment.
When the front passenger airbag is deployed in an accident, in‐
sufficiently secured testing and measuring instruments become
dangerous projectiles.
– Secure test and measuring instruments on the rear seat.
Or
– Have a second person operate the testing and measuring
instruments on the rear seat.
1.4 Safety precautions when working on the cooling system
Danger of scalding by hot coolant
On a warm motor, the cooling system is under high pressure.
Hot steam/hot coolant can escape - risk of scalding.
– Wear protective gloves.
– Wear protective goggles.
– To relieve pressure, cover the cap of the coolant expansion
tank with cloths, and open it carefully.
1.5 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
running. 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.
WARNING
Risk of damage to components
Connecting or disconnecting electric cables or washing the
engine while it is running may damage components.
– Switch off the ignition before connecting or disconnecting
electric cables.
– Switch off the ignition before washing the engine.

1.6 Safety precautions when working on
exhaust 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 ex‐
haust 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
cutting the exhaust system.
– When cutting, use an extraction system or otherwise en‐
sure sufficient ventilation.
There is a danger of the damper element becoming damaged.
Do not allow the flexible joint to bend by more than 10°.
Do not subject the decoupling element to tensile force.
Do not damage wire mesh on decoupling element.

2 Identification
⇒ n2.1 umber, engine data”, page 4
2.1 Engine number, engine data
The engine code is also on the vehicle data sticker and on the
crankcase above the gearbox.
The engine number consists of up to 9 characters (alphanumer‐
ic). The first 3 letter part makes up the “engine code”. The sec‐
ond 6-character part makes up the “serial number”. If more than
999,999 engines were produced with the same code letters, the
first of the six digits is replaced by a letter.
Vehicles with four digit engine codes
Four-place engine codes are being introduced, starting with let‐
ter “C”. The first 3 places show the mechanical design of engine
and are stamped on the engine as previously. The fourth digit
indicates the output and the torque of the engine. The engine
performance depends on the engine control unit -J623-. The
four-digit engine code can be found on the identification plate,
the vehicle data sticker and on the engine control unit.
Note
The fitting locations for the vehicle data stickers may be found
in the ⇒ Maintenance; Booklet ; documentation.
