     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.

     Front Seat
Start by moving your seat as far forward as it will go.

Next, you have to remove the rear seat back cushion.

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.

Figure 11
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.

cyberjamb Comments: I have a 2006 BMW 325i E90. My driver's lower seat cover is cracked and needs to be replaced. How can I tell if it leather or vinyl? The area where is worn is the part of cushion nearest to the door that angles up and that is definitely vinyl but I am not sure if the seat is partially vinyl and partially leather or all vinyl. Can you help me out?

Keith Comments: I jUst want to switch the front seat backs only as I have wear on the driver seat. Can anyone help?
March 3, 2015
  Followup from the Pelican Staff: I don't believe this will work as they part attachments are reversed side to side. - Nick at Pelican Parts  
Gene Comments: Thanks Nick! I managed to position the seat vertically so that I could remove the fore and aft drive motor and then rotated the small gearbox flex shaft to drive the seat to the correct position for removing the seat mount hardware. I managed to repair the broken wirein 2 places! and now the seat works fine and I didn't need a new motor.

Gene Comments: I have a 2002 330ci with an electric driver's seat that won't go fore or aft due to a broken wire and I want to remove the seat for access. Unfortunately I can't get at the forward mount nuts due to the seat's position. Can I rotate the cross shaft with some Vice-Grips to move the seat aft about 1 inch?

Michael Comments: Hello, I wanted to know if I could replace the little rod/cable that connects to the seat motor and track/rail. If so what is the part number. Unfortunately someone left a coke under my seat and it ruined the cable when the seat was moved forward. 2007 335i .

BTW- Is there a way to remove the seat with it not being able to move back and fourth due to the busted/frayed cable.

RodneyW Comments: I hope this an appropriate area to ask this question. I'm 6'4 and tall in the upper body. I have a '11 328 sedan. When is cold out and seat foam stiffens up, what little of my hair rubs the headliner. I do keep my hair trimmed close. I'm ok if I sit tilted towards the center of the car and have the sunroof shade open. After driving for a while, the seats will compress and then I can sit upright again. In looking at the base of the car seat, I'm not seeing much I can do to lower the seat. Is there anything in the seat itself I can adjust. I'm too the point of having some foam cut out, but hate to spend the bucks on that. Any advice is appreciated!!
January 3, 2015
  Followup from the Pelican Staff: HHmmm. Nothing I can think of. If the seat is at the lowest point, not sure what else you can do. Maybe seat heaters, to warm the seat faster? - Nick at Pelican Parts  
JB Comments: hi Nick - regarding my questiong about E92 seats

Others have told me that the E92 coupe have the same seat modules in both side so it should work?..E91 & 93 have different modules each side..
oh the original seats are sports seats & so are the ones i wish to change into..
January 2, 2015
  Followup from the Pelican Staff: I don't have any data to support that. If the part numbers are the same, they will may require programming once installed. - Nick at Pelican Parts  
JB Comments: Can I fit a RHD leather cabin ,front and rear seats, etc..In a LHD E92

I realize the door panels dosen´t fit with regard to the window control buttons..

and the memory buttons on the driver seat will be on the passenger side..

but will it work otherwise? i dont think i need memory settings..

will I have to get some coding done?...
oh and what about the mounts..?
December 30, 2014
  Followup from the Pelican Staff: I think they will bolt in, but you should double check. Inspect the rails on each side and be sure one is not longer / shorter than the other. None of the controls will work without rewiring the seats. - Nick at Pelican Parts  
rud Comments: I have a 2006 330xi The Thigh support on the pasanger side handle came off do you have a way to fix this or the part to replace it

josh 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?
