Note
♦ The following description refers to vehicles fitted with “On‐
board diagnosis” OBD.
♦ The OBD monitors all components and part systems influenc‐
ing the exhaust emissions quality.
♦ It is possible to carry out an exhaust emissions test only when
all units of the emissions testing station are connected prop‐
erly and joined to each other according to the operating in‐
structions.
♦ All work to be performed is displayed by the emissions testing
station .
Conditions for testing
•
All test conditions and data required for exhaust emissions test
are found on EET data sheet for the respective engine.
•
•
•
•
Automatic gearbox: selector lever in “P” position
Manual gearbox: gear lever in neutral
Parking brake applied
12V battery fully charged (if battery charge is too low, raise
idling speed if necessary).
– Perform exhaust emissions test according to instructions on
display.
Vehicle data input

♦ Registration number
♦ Key numbers
♦ Vehicle identification number
♦ Fuel type
♦ Mileage
The following vehicle data can be found in the vehicle registration

There are different ways to enter the specified data:
♦ 1. By manual input
♦ 2. By automatic data acceptance from the exhaust-emission
station database
Note
♦ Regarding Euro 6 vehicles with manual gearbox and infotain‐
♦ Euro 6 vehicles with automatic gearbox, manufactured from
week no. 48/18 do not have idle speed limitation any more.
♦ If there is no ESP or softkey in the infotainment system to de‐
activate the speed limitation, the governed speed can be
measured using the engine speed limited by the control unit.
To do this, all the EET specifications must be entered man‐
ually.

♦
For all Euro 6 vehicles an opacity figure of max. 0.25 m ap‐
plies.
Deactivation of idle speed limitation of Euro 6 vehicles with man‐
ual gearbox:
– Switch on ignition.
– Switch on infotainment system.
– Press Home function button.
– Press Vehicle function button.
– Press Setup function button.
– Press ESC system function button and deactivate TCS.

Note
♦ When performing the exhaust emissions test for Euro 5 vehi‐
cles, the respective engineer must always use the vehicle-
specific exhaust emissions limit value indicated on the type
plate.

figures (2.5 m or 1.5 m , depending on date of initial reg‐
istration) must be used.
The nominal speed can only be entered manually.
If the opacity figure of Euro 5 vehicles on the EET data sheet is
different from the value indicated on the type plate, enter the type
plate value manually.
Inspection
– Inspect all exhaust emissions relevant components.
– Check if exhaust system is complete and check for leaks and
damage.
Procedure
– Follow instructions from exhaust gas testing station .
