Rated values:
- A) idle speed - 750-1000 rpm
- b) CO content - 0.2-1.2% on the gas analyzer.
If the data obtained during the test does not correspond to the nominal values, then check the condition of the low pressure supply hoses, as well as the solenoid valve of the fuel vapor recovery system.
If you carry out all the maintenance work on the car yourself, we recommend having the CO content checked by an AUDI repair shop. In the workshop, along with the check, the self-diagnosis system will be interrogated and records of malfunctions that have been eliminated will be deleted.
