in one of your fuse boxes on the car there will be a fuse marked SH or sometimes its a odd looking fuse with the metal strip on the outside either way its the only one of its kind in the fuse box. This is a shunt fuse switch ignition off and remove key wait 5 mins then pull this fuse and go and have a cup of tea. Replace the fuse and then just wait till the plimp key works the central locking then start the car and take it for a 30 min drive trying to use motorways, hills and normal streets to drive down. this will reset your ecu and relearn the adaptive drive cycle,s
