Test conditions for vehicles with EOBD
•
Faultless function of the engine without extraordinary inequal‐
ities in the engine running behaviour.
•
Oil temperature at least 80 °C
•
Air conditioning switched off
•
The readiness code is generated for all exhaust gas systems
and components according to homologation. The exhaust
emissions warning lamp in the dashpanel insert does not dis‐
play an error.
•
If the readiness code was not generated, it will need to be
generated. The best way to do this is via a test drive or using
the vehicle diagnosis tester. If necessary, check why the sys‐
tem or components has not yet been tested while the vehicle
is moving.
•
No fault from the exhaust-related systems is stored in event
memory (the exhaust emissions warning lamp in the dash
panel insert does not indicate a fault) – query the event mem‐
ory

Caution
♦ A lit exhaust emissions warning lamp in the dash panel
insert indicates an error in the exhaust-related systems.
These faults (including sporadic ones) are stored in event
memory.
Resolve all identified exhaust-related faults, including sporadic
faults, when reading the event memory, before the exhaust
emissions
test
⇒ "6.7 Connect diagnostic unit", page 145
After deleting the event memory, the readiness code must be
re-generated. The best way to do this is via a test drive or using
the vehicle diagnosis tester.
Test conditions for vehicles without EOBD
•
Faultless function of the engine without extraordinary inequal‐
ities in the engine running behaviour.
•
Oil temperature at least 80 °C
•
Air conditioning switched off
•
Event memory (01- Engine electronics) is not read
Connect the test equipment
– Connect the tester in compliance with the Owner's Manual.
Connecting the diagnostic unit to the diagnostic connector
⇒ "6.7 Connect diagnostic unit", page 145
– Start the engine, allow it to warm up to the operating temper‐
ature (the best way is to drive it) and allow it to run in idle.
– Perform the exhaust-emission analysis.
