E60 Sports seats into E39?

[westaussie323i]

Does anyone know if the sports seats out of an E60 (not M5) would bolt into an E39 and then function....perhaps with minor wiring changes. Alternatively did the E39 have the sports seats with the split back rests etc at any point

I can't answer your question regarding E60 seats. My guess would be that they are not a direct swap, but that's entirely a guess going on that I've never seen it done before. With that being said, why would you want them? The E39 sport seats are fantastic. In my opinion, they're both more comfortable and more supportive than the E60 sport seats.

As for the second part of your question; no. The E39 was never sold with sport comfort seats. They were only available on the E38 sport models. Good luck finding a set for sale in Australia.

If you're interested, I have spare set of normal comfort seats (with the split back and lumbar support) that I would be happy to sell you.

Thanks for the reply ...do you think they might go into an E21 Baur Cabriolet?
how much are you wanting for them...any chance of a pic or two

Do you mean will the E60 seats go into an E21 or will my comfort seats go into an E21?

I doubt either will be a direct bolt in, but anything is possible. Depends how much work you're wiling to put in.

The E39 has the mounting points built into the rails, so I suppose if you're willing to drill through the floor of your car and there is nothing in the way, you could put them in anything. They're electric though and I'm almost certain the plugs will be different to anything in an E21, if the e21 even has electric seats in the first place.

I will pm you with some photos and price for the seats.

The issue I see is...when you jump generations...not only is the design architecture different...but you also have a different wiring set-up.

The generation prior to the e38/e39/e46/e53...used a lot of direct wiring...then in our generation, BMW went to the Can/Diagnostic/I, K, M, P communication bus that allowed communication between not only components on the same bus...but it allowed communication to pass from "GATEWAY modules to other modules...thus reducing the amount of wiring required in the car.

Now, the new generation BMWs use the CAN, MOST, Byteflight, and LIN communication bus set-up (probably can find more info about it on Wikipedia or google). So, more than likely, the seats from an e60 are going to require special wiring etc, since they will no doubt not be able to be plug-n-play and communicate over the now antiquated communication bus in the e39:

So in other words you may potentially breach communication to other systems ?!

Actually you can just find the positive and ground them, it can work as a simple electric seat without the memory function. For that it didnt require the bus systems.

Having a new-looking pair of E60 seats, destined, I hope for my nice E32 iL, are you saying all they need is power to operate? I tried that with no result, but the wires chosen were an educated (or not) guess. My seats even came with the male-plugged pigtail wiring stub. I've been looking for a solution to this for a long time and am fine with non-memory power seats!

Don't guess at wiring. Use WDS. It takes a while to get used to but you should be able to find full color coded wiring diagrams for the seats.

Nice. Thanks to the BimFo server glitches for the doublepost.

Goodness. geargrinder, thanks! I hope that ends my search for adequate wiring diagram(s) for this, after many,many months of delay, doing other projects. These newer seats should eliminate my frau's complaints about the old and not so comfy original seat (hard, cracked, split leather, et.al.).

I apologize if anyone thinks the thread was hijacked. Having owned and enjoyed my '89 735iL since 1994, a car with untouched engine in 270k+ miles, with newly redone self-leveling rear suspension, it was my first and still is my favorite BMW of all, despite having owned many others, including the departing 745Li. IMO opinion, it was the marques best ever.

Thank you, thank you. :redspot

There's a Bright Red 850i, the 745Li and an R1100RS absent in that, but.....
