Changing Driver's Seat Position Problem
This button (see attached image) to change the driver's seat position won't work unless I move the seat forward/back first from the side button.
But on my passenger's side, the button works fine without having to move the seat forward/back first. Is it programmed to work like that? |

I would check the seat control module to see if any thing is loose or if a wire is chaffed. Perhaps something got stuck under the seat (or perhaps a rear passenger’s foot) somehow has caused a loose wiring connection since you can get the easy entry switch to work if you move the driver’s seat.
The upper button (S159 easy entry button) is connected to the seat control module (S32) and is #18 & #19 in the wiring pin out for connector A93*1B on the seat control module. You can see the location of the seat control module below: A93*1B

There are some preconditions for the button to function. It would be dangerous if the switch was active while the car was in motion.

Hugo, I tested it when the car was stationary and both doors were open. And yet somehow I need to move the seat little bit from the side button before the easy entry button works.

ISTA diagnostics has a “seat adjustment normalisation” routine that is used to relearn the adjustment parameters, essentially restoring them to factory settings. Running this routine would be my first diagnostic step. If you don’t have the software you can ask your local BMW dealer or well-equipped indie shop to do it :-) It’s in the “body > safety function” group. |

Wow, thanks for the tip Hugo. I will definitely try this the next time I visit the dealer. Surprisingly, last month I got a call from the dealer and being told there's a recall for the condenser on my 2013 640i gc. So I'm just waiting for the part to come and will give them a visit.

I also noticed that in some cases a seat would not move forward if it is in a high position, it would move down first and than forward. Not sure if that is applicable for you. |

Not sure about the high position, like I said, if I press the seat button first then the upper button will works. But I will give it a try tomorrow |
