The TC consists of a turbine and a compressor.
The turbine is driven by the exhaust gas flow. A

The size of the TC is designed to produce a charge
effect even at medium engine speeds and lower
exhaust gas flows. This means that, when the engine speed is high and there is a large amount
of exhaust gas, either the boost pressure of the
TC will become too high or its speed will be too
high. The TC must therefore be regulated. The
best regulation is achieved by an electronically
controlled wastegate control valve. The wastegate
control valve controls the pressure on the
membrane in the boost pressure regulator.
The wastegate control valve is actuated by the
PCM with a PWM signal according to a map. The
boost pressure is applied to the wastegate control
valve via the pressure line from the compressor.
This pressure is passed to the boost pressure
regulator via the wastegate control valve. This
opens the bypass valve using a linkage. This
channels a portion of the exhaust gases around
the turbine. If the wastegate control valve is
actuated by the PCM, a bypass is opened in the
wastegate control valve. This causes the pressure
which can act on the membrane in the boost
pressure regulator to be reduced. This occurs until
the boost pressure has reached a set value. By
actuation with a PWM signal, it is also possible to
partially open or close the wastegate control valve.
This results in a constant boost pressure and
therefore high torque over a wide range of engine
speeds.
Because the PCM calculates the boost pressure
using the signal from the boost pressure sensor
and the IAT (intake air temperature) sensor, the
atmospheric pressure and the temperature are
automatically compensated for. Because of this
compensation, the engine power is not noticeably
affected by variations in atmospheric temperature
or pressure.

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.

The acceleration of the flywheel at each power
stroke results in a change in the CKP signal.
During the power stroke, the combustion pressure
acting on the piston causes an acceleration of the
crankshaft and thus also of the flywheel. This is
apparent in the voltage curve from slightly higher
frequencies and amplitudes of the CKP signal.
Calculation of the ignition angle
Since propagation of the flame front in the air/fuel
mixture always takes the same amount of time, the
ignition of the air/fuel mixture has to take place
earlier or later depending on the engine speed.
The higher the speed, the earlier ignition must
occur. This ensures that maximum combustion
pressure is achieved immediately after Top Dead
Center and that maximum combustion pressure
acts on the piston.
When starting the engine, ignition timing is
determined by the CMP purely from the ignition
map and information on camshaft position (CKP
sensors) and crankshaft position (PCM sensor).
As soon as the engine is running, the following
data are used as a basis for calculating the ignition
angle:
• the engine speed,
• the engine load,
• the coolant temperature and
• the KS signal.
The ignition angle has a major impact on engine
operation. It affects
• engine performance
• exhaust emissions
• fuel consumption,
• combustion knock behavior and
• engine temperature.
The higher the engine load, i.e. the torque demand,
the richer the air/fuel mixture, the longer the
combustion period and the earlier the ignition. The PCM calculates engine load using the MAF
sensor signal, the throttle position and engine
speed. This is done using ignition maps that are
stored in the PCM. The ignition timing is adjusted
according to the operating condition of the engine,
for cold starting for example.

The ignition maps were calculated in a series of
tests. Particular attention is paid to the emission
behaviour, power and fuel consumption of the
engine. The ignition map is stored in the data
memory of the PCM.
By adjusting the ignition timing it is also possible
to influence the engine speed to some extent
without having to change the throttle valve position.
This has advantages for idling stabilization, as the
engine speed and hence the engine torque respond
far more quickly to a change in the ignition timing

actuated) or opened (actuated). Each cylinder has
its own injector. The injection is accurately dosed
and takes place at a time determined by the PCM.
Injection takes place immediately in front of the
intake valves of the cylinder. The injectors are
actuated ground side via end-stages integrated
into the PCM and using the signal calculated by
the engine management system. Power is supplied
via the Powertrain Control Module relay in the BJB.
The injected fuel quantity depends on the opening
time, the fuel pressure and the diameter of the
nozzle holes.
The fuel metering is determined via open or
closed-loop control.
The open control loop differs from the closed
control loop in that the lambda control is
deactivated.
The PCM switches from closed to open-loop control
if the HO2S cools down to below 600°C or fails, as
well as when accelerating, coasting and at full load.
Regulation of injected fuel quantity via the PCM
involves:
• controlling the fuel pump,
• calculating the required quantity of fuel forengine starting,
• observance of the desired air/fuel ratio,
• calculating air mass,
• and calculating the fuel quantity for the different operating states and corresponding fuel
adjustment measures.
Open loop control
Open loop control is used primarily for fuel
injection, as long as the signals of the HO2S are
not involved in the calculation of the PCM.
The two most important reasons that make it
absolutely essential to run the engine without
lambda control (open-loop control) are the following
operating conditions:
• Cold engine (starting, warm-up phase)
• Full-load operation (WOT (wide open throttle))
Under these operating conditions the engine needs
a rich air/fuel mixture with lambda values below λ
= 1 in order to achieve optimum running or
optimum performance.
It is possible to keep this unregulated range very
small by using a broadband HO2S.
Closed-loop control
Closed loop control ensures strict control of
exhaust emissions in conjunction with the TWC (three-way catalytic converter) and economical fuel
consumption. With closed loop control, the signals
from the HO2S are analyzed by the PCM and the
engine always runs in the optimum range of λ = 1.
In addition to the normal HO2S, the signal from the
monitoring sensor for the catalytic converter is also
included in the control. The lambda control is
optimized on the basis of this data.
Certain factors such as wear, component
tolerances or more minor defects such as air leaks
in the intake system are compensated for by
lambda control. If the deviation occurs for a longer
period of time, this is recorded by the adaptive
(self-learning) function of lambda control. In this
instance, the entire map is shifted by the
corresponding amount, to enable control to
commence once again from the virtual baseline.
These adaptive settings are stored in the PCM and
are also used in open-loop control conditions.
If the adaptive value is too high or too low, an error
is stored in the fault memory of the PCM.
Oxygen sensor (HO2S) and catalyst monitor
sensor
A broadband HO2S is used as the HO2S. The
HO2S is located in front of the TWC. The catalyst
monitor sensor is located in the center of the TWC
so that it can detect any deterioration in the
cleaning performance of the TWC more quickly.
The HO2S measures the residual amount of
oxygen in the exhaust before the TWC.
The catalyst monitor sensor measures the amount
of oxygen in the exhaust gas after or in the TWC.
Both the HO2S and the catalyst monitor sensor
transmit these data to the PCM.
The broadband HO2S works at temperatures of
between 650°C and 900 °C. If the temperature
rises above 1000°C, the oxygen sensor will be
irreparably damaged.
To reach optimum operating temperature as quickly
as possible, an electrically-heated oxygen sensor
is installed. The heating also serves to maintain a
suitable operating temperature while coasting, for
example, when no hot gases are flowing past the
oxygen sensor.
The heating element in the HO2S is a PTC
(positive temperature coefficient) resistor. The
heating element is supplied with battery voltage as
soon as the Powertrain Control Module relay
engages. The HO2S is earthed via the PCM. As
the heating current is high when the element is
cold, it is limited via PWM in the PCM until a certain
