Nissan x-trail 2005 idle up and down 1200 to 2000 rpm 1- key on 3 sec 2- 5 pedal strokes in 5 sec 3- wait 7 sec 4- press the pedal and wait for the engine light to flash at least 10-15 times and when it stops release the pedal and start the engine then engage the D while holding the brake you should see the rpm drop and stabilize around 800-900 rpm let the engine run 20 sec works for me
