  1. 1.1.1. Engine at operating temperature.

  Information
  1. Adaptation values are deleted or stored in EEPROM when ignition is switched off after control unit run-on has ended.
  This depends on the run-on period of the engine compartment purge fan.
  
  The run-on period of the engine compartment purge fan AFTER ignition is switched off depends on the engine compartment temperature.
  
  The run-on period is as follows at the following engine compartment temperatures:
  - < 45 °C: approx. 50 seconds
  - 45... 70 °C: approx. 200 seconds
  - > 70 °C: up to 20 minutes
3. 1.3. Switch off ignition.
