Weak Seat frames in '84 and '85 E30s (318i and 325e) BMWs.

Hi Jeff,
I've had this problem on my old '84 318i. The upper inside seat
frame snaps at the weld on the corner. It's not too bad of a job to
pull the seatback off, strip off the upholstry and bring the frame to a
welding shop.
Here is a list of the seat problems I've seen/fixed:
- my '84 318i, drivers seatback broke in 2 places (corner and 1/2way down)
fix: stripped seat down and had frame welded, good as new
cost: $10 and 2 hours
- friend Hanks '85 325e, drivers seatback corner and bottom frame snapped
fix: stripped seat down and had frame welded, good as new
cost: $20 and 4 hours
- friend Dave's '84 318i, drivers seatback corner and general collapse
after he loaned the car to his heavy brother for a few weeks
fix: he replaced the seat with one from an '87 or '89 325
cost: $200
The '84 and '85 E30 seem to have a real problem with the seat frame.
I'd upgrade to a newer seat ('86-'91), they bolt right in, if you
can afford the $200. Otherwise, start looking for a welding shop.
hope this helps...
Dale
'95 M3 4k
'89 325i 124k (perfect cloth seats)
'86 325es 111k (perfect leatherette sport seats)
'84 318i 128+k (perfect structurally leather seats) (you never forget a BMW)
PS: if this is your only transportation, do the passenger side first,
then install the pass. side on the drivers side with the seatbelt
receiver swapped over, it fits, swap back after fixing the drivers
side. Been there, done that.
Here is an acid test I forgot to mention for testing the seatback frame:
- Lean the seatback forward as if getting in the back seat.
- grasp the upper corners in your hands and twist,
push forward on one side and pull back on the other
- if it twists, the frame is broken in the seatback
- if it doesn't twist, the frame is broken down below
- I've never seen a problem with the ratchet mechanism,
even thought that is most complex part.
Procedure for stripping down the seat.
- Remove headrest. Should be able to just pull it straight up out
of the seat.
- Remove plastic levers on either side of seat back. You may need a
flat-tip screwdriver to convince these things, and they may not want
to stay on when you reinstall them. Fortunately they are cheap at the
dealer.
- Remove hard cover on rear of seatback. Two #2 phillips screws in
the bottom of the hard cover, slide the cover up and off. Take care
working it around the side lever(s).
- Two #3(?) phillips screws hold the seat back on, remove them and lift
the seat back up aprox 6", and it's off.
- Remove upholstry.
