Hi guys i brought some red leather saloon m3 seats, i currently have m sport seats which are heated and electric bolsters. Am i right in thinking i need 4 connected to 9 (both +) and 8 you connect with 13 (both -)? Will this allow me to move the seat back and forth ect? Also the seats i brought were already retrofitted into a prelci, they have 3 black wires not connected to the module or air bag wiring just hanging.

I still do not know what is up with the 2 wire colors not matching but I haven't reversed them. I used iCarly to clear the Airbag codes after the bypass was installed and no problems since.

Awesome thread guys! I was hopping someone could help me out though. I just swapped out my basic seats ( no heat or power) for a pair of m-sport heated (bolsters but no power movement) I ran power for the bolsters and heat, both lines to the junction box (pins 34 and 38) as well as grounds and switched on pin 5. All connections are run to the original positions in the proper plugs. Bolsters work but I get no lights on the het switches and no heat. Anyone have an idea? I did not run an additional k can for either seat and if I read correctly I only need the drivers side anyways.
Coding was done with my icom with Ista p and was successful.

hello
you'll need to run separate heating pwm wire from JBE to both seats

Aren’t those the connections at pins 34 and 38?

oops, yes, they are
when i added seat heating to my car it started to work even without heating
so may be if you have lci car your JBE do not have these circuits soldered or you put 34 and 38 to another jbe plug

This is the retrofit pdf I used. 05/2009 build date

so you need to test all connections with multimeter, voltage on always-on and switched positive, and try to activate heating using inpa or rheingold

Just found that my seat module is missing the pins for can h and l... looks like I need another module

Power is at the 30a lines but no power at the 10a line.

[david in germany]

After reading, there is no Can lines to mine. Everything is wired correctly though. Tomorrow I will receive another switch assembly to try. I hope that is it.

did you checked 10a line when key inserted and ignition enabled ?
do this car have efficient dynamics ? do your battery charged ?
you'll need CAN only if you have big(20x15cm) seat module under seat

Efficient dynamics and tested with car running.

then you need to check why there is no positive in 10a switched fuses

Looks like in the TIS my divers seat needs to be powered by the x11008 instead of the x11006 as it is wired.

Passenger needs to go to the x11001 as it looks

https://www.newtis.info/tisv2/a/en/e...s-side/uzRp4LF
The retrofit pdf has them both going to the x11006..

Or am I reading this wrong?

the retrofit pdf can have errors
tis also can have errors sometime
but in that problem probably tis is correct

I have pin removal tools on the way and when they arrive I will swap the connection to the x11008 as the new switch I received had the same problem.

The pdf is also dated 2008 that I was using and my car is an 2009 build.

[david in germany]

So swapped the power to the power indicated in the tis, still nothing, I tried to activate the seats via inpa but no communication with either module. I can only assume now I have the wrong connection at the nfrm. Tomorrow I will retrace everything.. (again)

[david in germany]

Retraced, everything wired to where it should be... nothing.. I give up.

Ok, tried one more thing,

hi, first time posting, and am hoping I’m in in for an easy job. I have 2 2011 e90s, and am looking to swap some stuff before I sell one. One has manual heated seats and the other has powered heated seats. I want the manual seats but just the seats to go in the powered seats place but remaining the power seat function in that car and vice versa, if that makes sense. Am I going to be able to swap the seats and plug?
