Hi,
I did install comfort seats instead of my standard seat. I can give you a lot of help, but first I need to know some details from you. Your standard seats, are they manual or electric, if electric do they have memory (driver or both), do they have heating? and finally do the seat belts have one or two pretensioner (drive & passenger). As for your new Sports Seats, I presume both have memory, but please advise do they have heating, climatization (ventilation), active function and finally do the seat belts have one or two pretensioner (drive & passenger).
Knowing above data, will help me give you step by step guide to retrofit your new sports seats. Thanks.

This is a correction to my earlier post.
I did install comfort seats (almost similar to sport seats from wiring point of view) instead of my standard seat. I can give you a lot of help, but first I need to know some details from you.

Hi,
Please accept my apology for delay in reply, following are main steps to install your new seats:
1. Make a complete software update to your car at your BMW dealer. This step is only needed if your car ahs an old software version, Current software version is 23.1 (I think!)
2. Disconnect main battery cable during retrofit operation to avoid getting error messages which need to be deleted at a BMW shop. Your seats are connected by a wiring harness from the vehicle, each seat has two plugs, a large yellow rectangular connector which serves the restraint system (air bags, belt pretensioners..etc) and a small power plug that fits into the seat module located under the seat.
3. If your both original seat and new seat have the same pretensioner system (e.g. one for each seat) then no wiring modification is needed for restraint system. If for example, the new seats have two pretensioners instead of one, then a wiring modification is needed.
4. It is strongly recommended you transfer original seats pretensioners to the new seats to avoid any error message.
5. Remove old seats from the cat (two screws Torx 50 at front side), replace pretensioners to the sport seats as in 4 above and install the sport seats to your car.
6. Connect the yellow plug to corresponding club in the new seat and fit the small black plug to the seat control module.
7. Reconnect battery cable and test the seats for proper operation.
8. Now every time you will need to update the software of your car, you will get an error message from the seat modules as these do not belong to your car but have been coded to the car of the comfort seats. This could avoided by one of the following solutions; every time you make update, remove the small power plug from your sport seat module and fit it in the modules of your original seat only during update, alternatively you can thru BMW dealer make a sports seat retrofit which will request new seat modules to be installed, this will cost you about 700 Dollars.
I hope above information is OK and should you need any additional information, please do not hesitate to contact me.
