8.2 Exhaust-Emission Analysis on Models
with Diesel Engines
Note
The exhaust-emission analysis must be carried out according
♦
to the valid national legislation of the particular country.
The work room for the exhaust emission analysis must satisfy
♦
the applicable national and regulations in the country con‐
cerned.
♦ When possible the exhaust emission analysis should be car‐
ried out immediately after the road test.
Secure the front flap in the first stop while measuring to reduce
♦
the noise.
Perform the following visual inspections and comply with the
♦
test conditions before performing the exhaust emission anal‐
ysis:
Visual inspection
♦ Functional crankcase ventilation
♦ Fuel system and injectors must be tight
♦ The exhaust system must be undamaged, leak-tight and com‐
plete
♦ All vacuum hoses are connected
Vehicles with catalytic converter
♦ Catalytic converter is fitted, leak-tight and undamaged
Vehicles with diesel particle filter
♦ Diesel particulate filter is fitted, leak-tight and undamaged
♦ Senders for Diesel particulate filters and their lines are firmly
integrated and are connected to the Diesel particulate filter
and are fully-functional
Test conditions for vehicles with EOBD
• Faultless function of the engine without extraordinary inequal‐
ities in the engine running behaviour.
• Engine temperature, min. 80 ℃
• Air conditioning switched off
• Readiness test for test Readiness code has been generated
(i.e. is in state 0000000 - all of the systems supported by on-
board diagnostics are tested at least once). Warning light for
exhaust system in the dash panel insert does not indicate a
fault.
• If the readiness code was not generated it will need to be re-
generated (the best way to do this is via a test drive or using
the diagnosis device).
• No faults from the exhaust-related systems are stored in event
memory (the warning light for the exhaust system in the in‐
strument cluster does not indicate a fault) – query the event
memory
