F chassis seats into E chassis

smrtypants44 · 08-05-2018, 09:09 PM

Has anyone on here successfully retrofitted F seats into an E car?

BourneJack · 08-05-2018, 09:15 PM

Great one

Luizbaum · 08-06-2018, 11:58 AM

I would also like to know if it's possible.

delmarco · 08-07-2018, 11:37 AM

I doubt it!
I know same year vehicles can switch seats (like a 2007 X5 or X3 seats can fit in a 2007 E90) but new model years don't plug and play into older model years.

Also BMW puts a lot of passive restraint tech into the seats themselves which would make this job annoying!

smrtypants44 · 08-09-2018, 11:44 PM

So it works....

had to re-pin/swap the seat plug, swap seat modules, swap the seatbelt/pretensioner and fab on a seat position sensor but all the features work (even power side bolsters which the old seats didnt have) with no airbag errors. I haven't checked whether memory works yet.

However, i have a "electrical malfunction error". Buuut, if i put the old seat back in the same error pops up when i try and clear it, so i must have yanked a cable too hard or something....

Hey man this was two years ago so I’m sure you figured it out by now lol. Could you please tell me how to do this I just got a set of 435 seats for my 135 and I need to know how to wire them up. I’d appreciate it so much if you responded. My phone number is (779) 254-7430 and email is jadenswilliam@icloud.com. Please message me you would save my life and a whole lot of time lol. Thanks

miguelito_e91 · 03-19-2021, 11:48 PM

Hey like the other guy before me said, it's been two years. Can you please show us how to do this. I installed a 430 seat into my e90 and it's working fine, heated is the only thing that doesn't work. Long story short, if it's plugged in I get abs warning, airbag warning, stability control warning seatbelt warning all at the same time, and their intermittent, about 30 seconds. Any help??? My email is mmarroquin004@gmail.com

whyzee125 · 03-27-2021, 02:58 PM

I think the e chassis seats look nicer but being that you went to sport seats from non sport that's a definite upgrade

smrtypants44 · 03-27-2021, 07:57 PM

What have you done so far?

We’re you talking to me? Well not much to be honest I still can’t figure these seats out to be honest. I’m back on here trying to find something that will make sense.

so you need to buy a salvage e9x seat harness on ebay, take all the pins out and repin the f3x seats using the e9x "plug". Just match wire colors and locations to your current seats/the e9x seat harness.

Well what we have been doing is taking the old seats connectors and re pinning them onto the new seats. The only thing is we cannot figure out what way the seat controls get wired up. All the motors are wired in correctly, but the control panel doesn’t make any sense. The whole thing is extremely confusing, but the position sensors did atleast just bolt right onto my new seats so that Is a plus.

If I'd like to do this swap in my car with lci non sport seats, will I need seat modules from a set of sport seats?

Everything you'll need is contained within the seat itself.

smrtypants44 · 11-27-2022, 12:39 AM

i ended up using the seat modules off my e82 seats swapped into the f2x seats.

codeterrorist · 06-01-2023, 04:27 PM

A bit of an old thread revival. I'm picking up F30 sport seats that have bolsters, memory, and heated and planning on installing them in my E90 LCI that has base seats with memory, heat and of course motorised.

From this thread; it looks like I need to:

- move the E90 seats modules to the F seats
- repin the F seats plugs to fit into the E90 module

Any pinout guide, what pin from the F seat goes to what pin holder on the E90 plug so that I can get heated, bolsters, memory and be adjustable of course?

Appreciate any help.

Not sure if you still need this, but information is in ista, best option. I will give it a try for you, but you'd really want to know the specific cars you got them from. Following heated sporr seat e90 guides will help.

Lumbar is self contained in the seat, just need power.

Heat requires adding wires from the fuse block (there is a fancy bmw name I forget), if you're car didn't have it originally, plus the switches.

Overall you can get every function working in an E car

Thanks for the reply. I'm still gathering all the information I believe I'll need. Don't want to take seats out only to find I can't finish the task and then having to put everything back the way it was.

My E90 seats are heated so is the F30 seats. The only difference between my E90 seats and the F30 seats are the bolsters in the F30.

From my research so far and finding different threads on multiple sites, it seems the driver seat is the easiest to do and would retain all original features and get the bolsters working as well once tapped for 12v and ground.

The passenger side seems to be the one that is more complicated.
I hope I can tackle it this summer!

What I'm looking for is a pinout in a diagram similar to this one for the F seats

Where it shows each pin and what it does.
