lumbar and bolsters not working

Questions for you guys out there:
I had a pair of black leatherette sport seats with memory and side bolsters but w/o lumbar, and I just swapped them to a pair coral red sports seats with memory, bolsters and WITH lumbar. After the new seats have been plugged in I noticed that the bolsters and the lumbar doesn't work, however the power and memory works fine.
Can anyone tell me what do I need to do to get the bolsters and the lumbar to work? I've search the internet but can't seem to find anything.

Thanks for your help,

Ok folks after many hours of reading and research i have found a solution that i tested today and both bolster and lumbar works Woohoo

now for thoses that will be in the same boat as me this is what I have done. hope that will help you save some reading time !

First:

remove the seats by following the DIY found in the diy section. Once you have done take the yellow plug (seat connector) under your seat and remove all three harness. I checked the following diagram to ensure which Pin powers my bolster and lumber:
http://www.e90post.com/forums/showth...=480313&page=3
check post #51 thanks to Dassammy for providing that info.

In my case pin number 9 was the steady plus used for lumbar and side-bolsters since my Coral seats build date was prior to 03/2007.
I also checked the connector coming out of the floor carpet and confirmed that i had no power in pin 9 but rather in pin 7 since my car was built after 03/2007. So now all that was left was to run power from the pin 9 to a new pin 7. Because pin 9 connector was too big to just do an automatic swap I needed to get a new smaller pin 7. Here are the list of what I purchased and needed:
- 2 Pin contacts - 61130006664 @ 1.98 each (I paid mine 3.70 each cause here in Canada we get f#$k like that )
http://www.ecstuning.com/ES164045/
- 2 self-strip clips - 61138364566 @ 1.59 (I paid mine 3.58 each cause here in Canada we get double f#$k like that )
http://www.ecstuning.com/Search/61138364566/ES165509/
- 1 electric tape
- 1 exacto
- 1 pliers


Ok now on to the fun part:
I needed my car to go get the parts so...i had to put everything back together lol. if that's your case then unplug battery, unscrew bolts, disconnect the yellow connectors...bla bla bla.
I removed the seat out of the car in order to work better.
I removed the harness out the connector and with the exacto cut the black tape holding all the wires together. You want to go as far as you can with the red/purple wire (pin 9) because if you attach the self-strip clip too close you won't be able to put the harness back inside the connector. Once you noticed that you have remove enough black tape simply use the self-strip clip and clip both the power red/purple wire (pin 9) and the newly purchased red/black pin contact. Because the original pin 9 wire was bigger i used the pliers to press on the self-strip clip in order to close it firmly. Then I used electric tape to wrapped the two wires including the self-strip clic together. Put as much as you feel is needed in order to protect everything correctly.
Now I inserted pin 9 back into its slot and as well inserted the new pin 7 in the number 7 slot. re-assemble all three harness inside the yellow connector and put everything back in place. Do the same on the passenger side. Reconnect the battery et VOILA!! You should now have your lumbar and side-bolster working.

This is the easiest and fastest solution I have found and hope that it will help some of you out there.
Enjoy and thanks to all of the people who posted before me (diy, comments and experience) - each one of you helped me

Peace,

Hey mate,
You first need to find out the build date of your M3 seats. Then look at the post number 51 on the following thread:
http://www.e90post.com/forums/showth...=480313&page=3
you then need to compare the connector on the seat with the one on the floor of the car. If they don't match then you will have misconnection between Pin 9 or Pin 7. In my situation on the seat I had the red power on Pin 7 but on the connector on the floor it was on Pin 9. So i had to take the power from pin 9 to push it on pin 7. So look at the 1st table in the link I posted above to know which power wire to need to change.
Hope this is clearer, if not send me a PM.

Good luck mate,

look under the seats mate or better yet if you also installed the rear seat just pull one of the side panel and there should be a date sticker on the back of it.

Yes and also figure out which power pin needs to be re-wired.
The whole thing took me 30 mins

Similar swap, questions about moving pins

Not to dig up an old thread but thats what im going to do...

See my attachment, do i basically have the right idea? (i believe i also need the GND, hence PIN8 going to PIN13. and both my seat and car are after 3/2007)
How do i actually move, (or duplicate, as the case may be as i imagine i still need a 12v going to PIN4 and GND to PIN8, for "seat module" right?) the pins?

I'd rather not cut off the harness at attach each wire manually, or is that not possible?

I havent removed the yellow shield from car harness just yet because i want some direction first.

thanks!

Ok, so this is an old thread, but I wanted to say thanks to the OP for finding a solution and posting the solution.

Just fitted M Sport seats in my SE E92 and this thread should help me get it sorted.
