1 When ignition is switched off press flap slightly past limp home position. 90° position must be changed manually. The processor shut-off delay has a duration of approx. 5 seconds. 2.Switch on ignition for approx. 15 seconds, switch ignition back off again and wait for processor shut-off delay. 3. Switch ignition on for approx. 45 seconds, switch ignition back off again and wait for processor shut-off delay. The learn-in procedure for the recirculated air flap is then completed.

i don't understand the term 'limp home position' could you be more specific with your terminology please. many thanks

it means the flap is in a position which allows the minimum amount of air into the engine. Google it and you find lots of examples
