M4 Seat Retrofit Seat Heating Issue

weshascar · 01-04-2021, 10:53 AM

Hello,

I just finished my installation of F82 M4 seats in to my Pre-LCI E92 335i. All functions of the seat are working as normal aside from seat heating. Nothing happens when you press the seat heating button. The button will not illuminate either.

My car is equipped with seat heating, memory, and lumbar support from the factory. The M4 seats I purchased have the same features. I purchased LCI modules with seat heating, lumbar, and memory and swapped them in to the M4 seats. The E92 connector was repinned to the M4 seat.

I have double checked my wiring, ensured the modules were correct and am still a bit perplexed. From my reading of other writeups, I haven't seen anyone else with the issue. I am getting the expected codes for headrest restraint and passenger occupancy.

Was hoping someone here might have some insight on the issue.

Thank you!
