WM 2X00IN Important Information On Adapting The DME Control Unit (Except BOXSTER SPYDER): Information

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

2. The following adaptations will be deleted automatically when you erase the fault memory (see information under  1)):
   • Mixture adaptation 
   • Lambda adaptation 
   • Camshaft adaptation
