Leather seat repair

The black leather seats are splitting at some seams on the lower ( butt contact area). I did a repair with black duct tape but the tape slowly curls and becomes a bit sticky. It is not a good solution. Is there a specific type of tape which could be used? I am looking for a quick and inexpensive fix so as to stem the damage at least. I do not want to use seat covers.

The problem with fixing the seam is that BMW sewed it from the inside out. Meaning they stitched the inside of the leather, flipped it right side out and mounted it onto the seat.

The proper way is to remove the leather and re-stitch.

BUT, I have had some success with one of these curved sewing needles.

The center/rear sitting area of the driver seat is very worn and would need a patch. Not really that concerned with how they look, only function and durability. Sewing seams like the way to go. Thanks. I think I may have an old leather sewing set from my hippie days of the early 1970's when hand sewed some sections of a 25 foot Tipi. The Tipi is stored under the house.

I was going to say use the special glue that comes wound round a reel and is applied with a needle, but some one beat me to it.......

Here's a fix that worked for me: Find a little-used passenger seat in a junkyard or parted-out car. Dismantle the seat and remove the cover and foam pad from the lower half as a unit, and transfer it to the driver's seat in your car (you'll have to take it out and disassemble it too). The upholstery is pretty much interchangeable -- there's just a little minor cutting to accommodate the switching on the driver's side.

That may be a good solution. I have had the seats out before to put new cables in for the power seat adjustments. When you say "dismantle", do you mean separate the back form the seat bottom. I believe that would necessitate the removal and reinstall of the power cables. They were a bitch to work on.

If you mean the bowden cables, none of those extend from the seat bottom to the seat back. There is one for the headrest, but the motor is inside the backrest too -- it's all self-contained. The only connection you have to worry about is the electrical cable that goes from the headrest motor to the control switch.

There is one oddity about taking the seat apart: the backrest clips onto the wedge-shaped hinge extensions standing up from the seat bottom frame in the diagram below. A spring mechanism holds the seat back in place on the hinge extensions, and it takes a little jimmying to get the clips to release so you can take the two halves of the seat apart.

There are many "pick n pulls" in my vicinity and they have a great web site which lists the year,make and model of all vehicles and their location on the lot. If you call they will tell you the color of the vehicle. I have gotten many parts as, unfortunately there are many older BMW heading to the grave yard. We will all join them someday! Thanks for the information.

As mentioned, finding a good passenger seat cushion is the easiest repair, probably no more than $25 at a pic n pull or regular salvage yard. Have seen excellent passenger seats more than once, usually tan/parchment. Black is a harder to find.
