Hi
I have stock e90 sports manual heated seats. I did swap F30 memory sports heated seats. Drivers seat works great no issue heating memory etc after some modifications
Problem pass seat- no heating. My E90 pass seat has only small black module for heating, the same sh. in F30 passenger seat has small black module for heating. I did some test: connect pwm signal from JBE to F30 passenger seat heating module to turn ON. Want work, I believe F30 heating module "understand" LIN signal only from FEM module. So?
1) I have read that I should add in pass seat the same module as in driver seat? Control heating via can bus...
2) Maybe someone has did some mods and use E90 pass seat heating module to work in to F30 pass seat?
Second option for me will be better, otherwise I will need from scrap yard plugs connectors the same as in driver seat + in passenger seat there is no hall sensors for memory function how to connect everything proper it will be nightmare..
Thank`s
