Does this mean that those of us who started with manual, non-heated, non-sport seats still have power running to each seat which we can then tap into for power bolsters and seat heaters? |

no, you need to have something electric - lumbar, bolster or heating

Sorry to revive an old thread. I did search for quite some time but mostly found information regarding when swapping between non-power vs powered seats.
My case is a bit different. I have LCI non-sport, electric, heated with memory (no lumbar though). I am swapping to LCI sport seats, fully equiped (electric, heated, memory, lumbar and bolsters). So, adding the power lumbar and bolsters, which I didn't have before. Am I going to need to rewire to be able to tap power for the lumbar/bolsters? Or is it plug and play and I will be able to use all the functions? |

Great tutorial.
I have an E91 LCI which had non-heated, non-powered seats. I now have leather with lumbar button. Can I get the lumbar support working using this guide , or am I wasting my time ? Thanks in advance |

Hope someone can help
E90 LCI - original seats -Manual, Cloth, NON-heated, with electric bolster (side button) - can't remember if the electric bolster worked NEW seats - Manual - Leather, HEATED, with electric bolster (not currently working) The heating does not work but Ive been told it is due to coding which I will attempt soon. I have also been told as the new seats are same but WITH heating only that the wiring is all the same and that I just need to code heating in Is this correct? also if swap is basically the same with just heating function, why does the electric bolster switch not work? many thanks in advance |

for sedan and touring passenger seat have differrent electrical config then driver seat to complete your retrofit you need additional wiring the coding of jbbf may be also required p.s. i'm selling the appropriate wiring in private sale section if someone decide that my comment is unacceptable, i'll remove it

Hi, is it an only way out to connect side bolsters if before there were seats without power?
What about airbag or belt tension plus and ground wires? Is it possible to connect with them? |

Reviving the thread again. I have an E91 which had manual heated seats and I swapped them for LCI manual sports, heated with side bolsters.
Using this thread, I managed to power the heating, but I am still struggling to make the boslters work. I tried with giving power to PIN7 and PIN9 but it didnt help with the bolsters. Can anyone give more ideas? Thanks! |
