My C30 (D5 GT, MY 2008) with electric seats does not remember the sitting position. As a first measure I replaced the batteries, did not bring any change. Then the:-) put the keys back, did not bring anything. If I turn on the two keys and both sitting positions directly in a row and close everything works. the seat drives when the door is opened into the last set position. But if a day is in between there is nothing left to drive. Finally, I open the door with my key, nothing happens, put the seat with the memory button in my position, drive and lock again. When I then get back in 10min later, the seat drives into the position of my OHL when the door is opened. Has anyone ever had this, or has any idea what that could be? Will the position be stored in the key or in the vehicle? Greeting Jens
