The front engine cover must always be fitted when
checking and adjusting the valve timing or timing
belt tension, as the timing marks for both camshaft
pulleys are provided on its front end.
Correct timing belt tension is ensured by the
automatic timing belt tensioner.
No direction of movement is specified when using
a new timing belt. If, however, the old timing belt
is reused, the direction of movement must be
marked prior to removal.
Once the timing belt has been correctly tensioned,
the engine must be rotated by hand two turns
clockwise at the crankshaft in order to allow a subsequent check of the timing belt tension and
adjustment.
Cylinder block
The cylinder block consists of three parts. These
are the cylinder block, the lower crankcase and the
sump pan. The cylinder block has five cylinder
liners made of cast iron, which cannot be replaced.
The pistons are made of a homogeneous aluminum
alloy with a graphite coating on the sides. This
coating serves to reduce friction and dampen noise.
The pistons are cooled from below via oil-spray
nozzles screwed into the cylinder block.

Inspection and Verification
NOTE:It is normal for a small amount of
combustion gas to pass into the crankcase. This
gas is scavenged into the air intake system through
the positive crankcase ventilation (PCV) system,
which incorporates an crankcase vent oil separator.
Some engine oil, in the form of a vapor is carried
into the air intake system with the blow-by gases
(this engine oil also contributes to valve seat
durability). This means that oil will collect inside
the air intake components and the turbocharger.
This is not an indication that the turbocharger oil
seal has failed. The turbocharger oil seal will not
fail unless the bearings fail first, which will cause
the turbocharger to become noisy or seize. Do not
install a new turbocharger due to oil inside the
turbocharger or the air intake components. If a leak
is detected in the oil supply or return tubes or connections, locate and rectify the source. Do not
install a new turbocharger due to an oil leak.
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical
or electrical damage.

System Operation
Smart Start
The PCM enables the starting process when a key
providing a valid code is read via the PATS. This
code is then verified in the GEM and compared
with the saved code. If this code is recognized as
correct, synchronization with other modules is
carried out. After successful synchronization, the
engine is cleared to start in the PCM. The PCM
connects earth to the starter relay, which then
connects power to the starter solenoid. As soon
as the engine reaches a certain speed, the PCM
disconnects the starter relay and so turns off the
starter. This protects the starter.
If the engine does not turn or turns only slowly, the
starting process is aborted by the PCM.
The starter is notactivated if:
• the engine is running (i.e. the engine speed is above a particular value),
• the PATS does not permit the engine to be started,
• the clutch pedal is not operated (vehicles with manual transmission),
• the gear selector level is not set to P or N (vehicles with automatic transmission),
• the brake pedal is not operated (vehicles with automatic transmission).
Emergency starting function
If the keyless vehicle system is unable to recognize
the passive key, the vehicle can be started via the
emergency starting function. In this case, there is a passive key mount on the
steering wheel. A PATS transmission/reception
unit is attached to this.
To start the engine, the passive key must be
inserted into the passive key mount. The Start/Stop
button can then be used to turn on the ignition and
start the engine as normal. To deactivate the
PATS, a transponder is fitted in the passive key,
which is read by the transmission/reception unit.
