In Reply to: Repair of driver seat posted by Sab on January 10, 2001 at 13:25:23:
Did the seat bottom on my 85 535i last week. Ordered leather from internet company because it is NLA from BMW. Your seat problem is probably caused by 4 machine screws on each side of the seat. These machine screws hold the mechanical gears in place that control and move the seat back. On my electric seats, the 4 machine screws next to the center console had completely separated from the metal base and the mechanical gears were no longer in contact with the seat. On the right side next to the door 2 of the screws had back themselves out and the other two were loose. Unless you are replacing the leather, the seats do no need to be completely disassembled to fix this problem. In order to repair this seat problem it would be best to remove the seat from the car. Remove the four bolts at the seat base and the seat belt bolt next to the drivers door. Disconnect the electical connections under the seat and remove the seat from the car. Remove the phillips screw that hold the plastic covers in place. The four machine screws are under those two covers. If yours have backed out completely, check for the screws on the car floor around the drivers seat. You'll need to line up the mechanical gears to replace the 4 screws but its not difficult. If you want the screws to stay in place use some locktite. If you need more instructions on fabric replacement put it on this site. I can help you with the removal and installation of leather for the seat base and what seat parts must be removed.
