Exhaust emissions test
This chapter provides information on the following subjects:
Exhaust emissions test for petrol engines ⇒ page 208
Exhaust emissions test for diesel engines ⇒ page 210
Note
♦ Please observe the country specific legal regulations.
♦ The exhaust emissions test described below has been cre‐
ated according to the legal regulations valid in Germany.
5.1
Exhaust emissions test for petrol en‐
gines
Special tools and workshop equipment required
♦ Exhaust gas testing station L -VAS 7320 A-
Note
♦ The following description refers to vehicles fitted with “On‐
board diagnosis” OBD.
♦ The OBD monitors all components and part systems influ‐
encing 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
properly and joined to each other according to the operating
instructions.
♦ All work to be performed is displayed by the emissions test‐
ing station.
Conditions for testing
•
All test conditions and data required for exhaust emissions
test are found on EET data sheet for the respective engine.
•
For bar code reading the EET data sheet must be printed
out.
•
•
•
•
Automatic gearbox: selector lever in position “P” or “N”.
Manual gearbox: gear lever in neutral
Parking brake applied
12V battery fully charged (if battery charge is too low, raise
idling speed if necessary).
•
Hybrid vehicles: the EET is to be performed on the combus‐
tion engine.
– Perform exhaust emissions test according to instructions on
display.
Vehicle data input
– Enter the following data:
♦ Registration number
♦ Key numbers
♦ Vehicle identification number
