Further to the report on the battery going flat in Robin Hecker's FG Falcon G6E I also had the problem and it was also related to the electric seat memory module and the green light on the driver's seat failing to extinguish. Mine was fixed under warranty about a month ago after many frustrating experiences.
Anyone having the same problem should check the operation of the light on the seat module and make sure it goes out. If it doesn't have your dealer check it and correct it if necessary. It could be the answer to your woes.
