In my '06 997S cab., the power seats keep the memory settings if you press the memory buttons manually, but the key memory doesn't seem to work anymore. It worked fine in the beginning (500 miles ago), but now, after clearing the settings and re-setting the key-seat memory many times as the manual states, the function just doesn't work anymore. The key is storing the settings, because the seat memory works for each key when you press the number 1 button (with the key on it), but when you unlock the door, nothing happens if the seat has been moved to a different position. All this worked before. Anyone have this problem or a solution?
