      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
