Thanks, but it was a T-40. The best way to get it out is with an L - Shaped Torx key.

Correct me if im wrong but E92's have folding seats standard right? I know you did this in the E90, good work finding those parts at those prices.

Thanks for the great writeup, msbc721! There is a small error in your parts list:

Quote:
Cable Holder ~ 72 11 8 177 700 4x (Not Required, But Opitonal)
Seat Back Lock Actuators Screw Hole Inserts ~ 63 12 1 374 075 [2x]
You need 2x cable holders and 4x screw hole inserts.

Do you remember what is the part number for the side bolster clips? The part number posted in the other thread was wrong.

Good Catch :-) I have yet to find a part number for that, if you find out please let me know.

Great DIY and great help. Here's the deal: I have 2 e90s and changing out the entire leatherette with leather from the other car. ie...one is premium package and the other is not. So, technically I have all the parts needed including hardware. To clarify, the donor car has folding split seats the "new" car does not. The only parts I'm thinking I might need to purchase are the plastic screw holders that expand when mounting the manual seatback release handles..... Thoughts???? Am I missing anything here?

Thanks, Steve

Excellent writeup. Folding rear seat is about the only thing I wish my 330 had that was missing. Great stuff, thank you!

Just completed this retrofit in my '07 e90 335i. Greatly appreciate the DIY thread! It was fairly easy and straightforward. A few item quantities are off though, as well as my car did not have the bolster clips, I was missing two LATCH covers, and I optioned to not do the middle belt.

If you have the seats/bolsters/headrests, but nothing else, here is what you would need:


Seat Back Locks
-Left: 52 20 7 112 863
-Right: 52 20 7 112 864

Seat Back Lock Actuators
-Left: 52 20 7 151 369
-Right: 52 20 7 151 370

Cable Holders: 72 11 8 177 700, [2x] (optional)
Seat Back Lock Actuators Screws: 07 11 9 901 299 [4x]
Seat Back Lock Actuators Screw Hole Inserts: 63 12 1 374 075 [4x]

Folding Seat Support Bracket: 52 20 7 161 259
Folding Seat Support Bracket Screws: 07 14 7 161 279 [2x]
Folding Seat Back End Support Brackets: 52 20 7 118 701 [2x]
Folding Seat Back End Support Bracket Torx Bolts: 07 14 6 952 304 [2x]

OEM Two Piece Middle Seat Belt (optional)
Upper Part: 72 11 7 132 245
Lower Part: 72 11 9 138 232

OEM Lower Child LATCH Covers (may need if yours are broken or missing)
ISOFIX Cover: 52207118674 [max 4x]

Side Bolster Clips (may need, my car did not have them)
Side Clip: 52207157536 [2x]

Finally will be implementing this great writeup!

I truly missed the convenience and utility of folding rear seats like I had in my E46 and have been searching an entire year for the availability of folding seats. My patience was rewarded via CraigsList with practically brand-new (low mileage) black Sensatec (matches my existing "leatherette" interior) setup complete with headrests and ski-bag "boot." And no way can you realistically find a complete folding rear set ensemble on eBay for $200 nowadays (one decent looking set is still for sale at $699 free shipping, while another set was $800 local pickup only on the East coast, though it did include front seats as well).

Since I will definitely require the detachable center seat belt to allow more unrestricted room with the seats folded, that will bump the cost of ancillary parts another $175 ($125 for the top half and $50 for the lower half) for a total of $325 plus shipping.

For the center support bracket:



Is there a top/bottom orientation, does it matter, or does it fit in only one way? There's an angled corner and a rounded corner so it would appear that it has to be installed in a specific orientation.

Been too long since I did the switch but I would guess the rounded end points up.
