Sorry for the double post... Keypunch error. Anyway, I had the same problem on my 89 525i. There is a cable that goes to either side of the seat back and into a gearbox under the front seat bottom. One of these cables either needs to be replaced or adjusted. It has a square end and fits into a socket on the gearbox. A small bracket is all that holds it in. If you go to the posted link, there is information on how to fix this problem on a 7 series... same on a 5er. Good luck!
