What to give everyone a quick update, please keep in mind I've never done any of the before, and it's tkaing a while to learn and proceed:
- bought part # 61131383776 from fcpeuro, as these are the exact female pins needed for the seat harness; I used a klein wire stripper to secure the wire to the connector; I'm sure there's a better tool, I just couldn't find it - bought pvc stranded 22awg wire from amazon, as this seems to be the exact size wire the seat harness uses - I was able to easily run wire from the passenger seat harness to the R2 connector in the back of the vehicle - I apparently need to run 2 wires from each seat harness to the A11 crash safety module (located directly under the idrive controller); this is evident after researching in newtis, but I cannot find a way to access the A11 crash safety module; I took apart the console a bit, removing the shifter and idrive controller, but then there's another layer of plastic that needs to be removed it seems to get to the A11 module, so..... - since my current seats do not have active head restraint, I may just unplug the active head restraint from each new seat, by pulling the back part off each seat and unplugging the connector - I may not do the coding myself, but it seems I need to add VO codes 456 and 453 to the FA, remove 459, then code IHKA (since the seats are ventilated), both SM modules, HU and BDC-BODY - If I do proceed with coding using esys, I'm hoping that because I haven't coded the ACSM, I won't get any safety warnings, since the current seats do not have active head restraint, and the new seats will have those unplugged, unless adding the other VO codes automatically triggers changes in the ACSM to look for active head restraints - It seems I can code out the active head restraints by changing AKS_LINKS_1_CD and AKS_RECHTS_1_CD in the ABG module to nicht_aktiv, but I have no idea if this can be done in esys without a token Any advice, thoughts or clarification on the above is appreciated |

update: driver and passenger ventilated front seats have been installed. Ran the can cables from the passenger harness to R2 can harness in the rear. Everything fit perfectly. Also installed the proper climate control module in the dash in order to be able to use the ventilated feature....I haven't coded a thing and everything is functioning properly! Well, except I get driver/passenger restraint warnings due to not connecting the active head restraint wires from each seat to the A11 module.
I have esys on my laptop, but I don't have the launcher, so I don't think I can code out the active head restraints in order to suppress the warnings. I'm at the finish line...any help is greatly appreciated! |

update: thanks to Shawn, I was able to get the software needed to finish this project. First, I updated the VO to include 453 and 456, and removed 459. I did not make these changes permanent by writing FA FP to VCM master...
Then I coded IHKA2, SM (1) and SM (2), HU-NBT and ACSM. But first, I needed to inject CAFD to IHKA and SM (since the seats and the climate control didn't exist before). Finally I FDL coded the active headrest, which is called aktive Kopfstütze - change passenger and driver to nicht-acktiv and the warnings disappeared. |

Quick update on my upgrade.
Both seats installed, coding to be finalized (only memory does not work). running the 2 22AWG cables was a peace of cake, and this was all what was missing to energize the passenger comfort seat. Result is great, it makes a reel difference from the stock seats. Thanks to Greg who helped me with the R2 connector I was a bit worried about the wiring but things were easier than i thought picture will come asap (need a proper cleaning of the car first ) |

Do you have pictures of the wiring, and which cables need to be replaced/go where? I have bought comfort seats as well, currently, the standard ones (no memory on each side) so need to perform the same operation for both seats. It is still unclear to me which additional cables I need to put in, as also I have no power whatsoever when I put in the seats. Thanks a lot for your support!!! It sounds complex, like you said, however hope it is doable. |

Hi all,
I am new to this forum. In the past 15 years I have driven multiple BMW's, and recently was fortunate to purchase a BMW X5 from the F15 generation. As this car is equipped with the standard Leather seats (2 electric movements inc. heating) and my previous BMW's all had sport seats, I decided to upgrade to comfort seats and purchased a used set. I was hoping this was plug and play, however, it is not, and hope I can seek some support over here. Although the connectors of the seats are the same, it appears that some wires are missing. The new set of comfort seats have memory, however, I am not so bothered if such will eventually not work. If I connect the cables to the new seats, nothing works. Does anybody have experience with such retrofit/swap? Would somebody be able to give me some guidance in which wires need to be added, I just need power on the seats and the airbags to work (memory is not so important if that is the complex part). Here below a picture of the seats which I purchased. I also have the backseat, but this looks to be almost similar to the standard one. Hope somebody can give me some guidance on the electrical portion! |

As I do not have memory at both seats, I suspect I am missing the CANBUS connection. Would this power the seats? As of now, both seats do not operate/move when plugged in with the wiring as is? Here below a picture of the connectors of the driver seat, the one above is from the donor car, the one below is mine. As you will notice, quite some wiring is missing. What I am being told by one of the forum members (great help), is that I only need to add the CANBUS wiring and it should work. What are your thoughts/advice?

Real Steel, were you able to get your seats to work and if so did you do it yourself or have it done? I have a set of conmfort seats and I really want to do the swap. I just don't know how to make it happen.

I cant speak much for the X5, but in my E90 when I swapped to sport seats I had to add or swap a wire that provided power to one of the motors (I dont remember which one), and I had to use the seat belt latch from my original seats. There was no coding needed. |

Hi there
I’m just doing the upgrade of my X5M50D sports seat to the X5M seats. Thank you sooo much for this write up you have really helped me a lot!! ☺️ As per all the comments my front drivers seat is working perfectly, but the passenger side seat is dead, apart from the lumbar controls. I have purchased 4 of the can bus wiring connectors from BMW, I will buy the 22awg wire today. I have found the diagram for the passenger seat connector so pins 5 & 6 are easy to locate and install, my big mystery is the R2 canbus connector in the rear?? Do you have a diagram for the R2 plug?? Can you tell me where the wires from 5&6 go to on the R2 box??? Your help greatly appreciated!!! Cheers legend 🙏🏼 Quote:
