You may have to remove the seats from your BMW E90 to replace them or service components beneath them, for example the fuel pump or front seat switches. In this tech article, I will show you how to remove the front and rear seats from your BMW E90. Once removed, you can repair items like the seat switches, the seat module or motors; or in the rear, the fuel pump or seat belt buckles.
Start by moving your seat as far forward as it will go. Then, remove the two T45 Torx mounting fasteners at the seat rails. (green arrows)
Disconnect electrical connector by sliding release tab with a flathead screwdriver and separating connector.
Now you can remove the seat from vehicle. Cover the door entrance strip with a towel or old blanket to protect it from damage. Then remove seat from vehicle.
To install reverse removal steps.
Next, you have to remove two fasteners at the center of the rear seat back cushion. (green arrows) Use a T45 Torx bit to remove them. (green arrows) The fasteners are located at the center of the seat back cushion, between the seat belt buckles.
Next, you have to remove the rear seat back cushion. This part is a little tricky, just because accessing the release in the trunk requires you to bend in an unnatural way. The green arrows point to the seat back lock.
You have to use a flathead screwdriver and lever release (green arrow) away from release stop (yellow arrow). While you lever, push seat back toward interior of vehicle. You will know when it releases as it frees up a bit from the body.
Now tilt the back seat cushion forward and pull up to remove from side mounting points. Once out, remove cushion from vehicle.
To install rear seat, reverse removal instructions.

Followup from the Pelican Staff: I am not sure about a used one. I have not done it that way. New ones do require programming. - Nick at Pelican Parts

Comments: Hi, when moving I had something spill in the back and it apparently ate away at the metal bracket rails that allows the seat to move back and forth. The car is manual non-powered seats. What do I need to do to get the seat to move back and forth again. Can I just buy a replacement part or do I have to buy a whole new seat?

Comments: Great instructions thanks. Worked well on my 2005 320i E90 exec. Saved me a lot of stress trying to access my wiring loom whilst installing a reversing camera one late Sunday afternoon.
