Lci sport seats in pre Lci

Grant Roach · 10-18-2023, 02:17 PM

Hi I am new here. I have a a 2006 325xi with heated and powered seats, and im looking to buy a set of sport seats from a 2011 335i xdrive. The question i have is there anything im going to have to do to get the side bolsters and lumbar to work? or is it just plug and play? i cant seem to find a definitive answer anywhere

EDIT: I installed the seats to find out the side bolsters and lumbar do not work so heres what i did.If anyone is having the same problem heres what I did to fix it.
All I have to do for the passenger seat was to jump pin 7 and 9 on the seat connector
The driver seat did not have a pin 9 so I took power from pin 4 and connected it to pin 7 and connected the 2 grounds pin 8 and 13 on the seat connector
And then for some reason my passenger seat occupancy sensor was throwing a code, so i just coded it out with NCSExpert.

Plug and play. All the controls for the lumbar and side bolsters are within the seat itself. Only thing you'll need to do is some coding, but it's minimal.

if you hadn't any bolster before, then bolsters in new seats will be unpowered

I just swapped lci manual heated sport seats into my 2006 330xi with heated power non-sport seats and had to do some rewiring. I had to rewire the 2 wires for CAN and jump power for the side bolsters to work. I didn't need to do any coding.

There's a DIY guide that explains the connector pinout. You just need to compare your current seat connector to the new one and make sure there is power where it needs to be and is controlling the heated seats correctly (can be via CAN or PWM)
