BMW E90 - Sport Seats Retrofit 

Nice job. Short and sweet with all the good tips and watchouts.

great video been binge watching your videos

Idk your specific specs, but generally, you’d need to pin 4 to 9 and then 8 to 13. Just look at wiring diagrams to understand. The bolsters have no power to them. So you need to hook them up to a 12V. Usually your heated seats are powered, so you just need to bridge a connection and ground

Where did you find the seats? I’ve been looking for a long long time haha! Looks good man!

Sick upgrade man! I was thinking of getting this myself but I’ve decided I’m going to sell my E90 a year or less from now. I want something economical but something I can still have fun in. The F31 330i, Focus ST, and Mazda 6 all caught my eye and they’re all economical and fun when you want. I love my E90 but the mediocre 17 mpg in the city is getting old. Love the sound but somethings gotta give. I had plans to buy m sport seats, new bumpers, etc. but I guess I’m just maturing a bit and want a economical car. I still hope to own a E92 M3 or F82 M4 afterwards but the e90 is gonna have to go. Channels like yours made me appreciate my e90 but man I hate growing up and wanting a eco friendly daily instead of a nice sounding straight six lol The m sport seats were literally the next thing I wanted to do but my mind wants a economical car and I caved. I’ll enjoy it while I have it but it’s a for sure thing now. Maybe one day I’ll buy another NA E90 in a manual for the nostalgia 😞 I’ll still be watching your vids even though I will no longer be spending anymore money on my E90 other than maintenance. Your videos along with other E9X guys inspired me to film some of my own DIYs but never get around to edit them, let alone post them lol Anyways, looking forward to the M3 videos!

I did the same swap and I also have the issue with the driver side bolster airbag not working.. hope you find a way to code it.. let us know if you do ..mine are black

does your e90 still pass smog with the muffler resonator and secondary delete?

How much are your old seats? Airbag connector, dies it have the Y connectors?

Have done the same swap on my e91, still haven't figured out the Side bolster thing though. Please make an update if you figure out how to wire it to make them work! :D

Does anybody know if you need to change the seat belt fasteners from the old seats to the new seats for the e92? I have the seat belt error. I have disconnected the battery and waited prior to changing the seats out.

Finally got a hold of the sport seats in the cinnamon/terra brown! It was a really good deal that I could not pass up! Also my old seats are for sale so if you are interested in my old seats, let me know! :) Also this video isn't really meant to be a DIY of any sort. It was more or less of a walkthrough of how to swap seats on your BMW E90. Justin Buice has an AMAZING video that goes really in depth on how to swap out your seats which you can check it out right here! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8EpoY41fPL4.html

It’s a coding issue. You just need to have them coded to the car since the car didn’t have the sports package from factory. Get it coded and it will work.

Dammit I knew the side bolsters wouldn’t work. Mine don’t either. Idk if it’s missing a connection to the airbags in the bolsters or something that can be solved with coding.
