I've had my E39 for over a year now and I have some serious back pains... I blame them all on these damn flat-backed seats....
So i've been looking around for a cure. Instead of shelling out a couple thousand for a pair of comfort seats I'm confident that I can either retrofit a factory lumbar bag/pump from another BMW seat (most likely an E38) or just go with an aftermarket kit.
Does anyone have any experience with this type of task?
I'm only 22, waay too young to be walking around like a senior.
i retrofitted oem lumbar on my sport seats. You need an air pump, rear bladder, and switch. You have to custom make the harness unless you buy the entire seat harness.

The car also received heated seats at the same time.

here is DIY link for a E46 but I would think it would be about the same. http://www.tmk.com/lumbar/index.shtml
I have the rare "standard seats" w/ 4 way power lumbar and heat, but they are not comforts. Odd...

i want to add in some tighter side bolsters.... after driving in a lot of new 3 series and 550s which have some insane side bolstering, my e39 comfort seats feel like a bench seat in a pickup truck. The side bolsters in the e60 550 squeeze your sides in and you sit really deep in the seat, like its hugging you. I want my e39 to hug me (that sounds bad)
Yea I know what you mean... My previous car was a denali with like 500 way adjustable seats.... It was like they were molesting me rather than hugging me.... it was great.
So i ordered an OEM Lumbar bag/pump/wires/switch for my driver's seat... A nice detailed write-up with plenty of pictures is on it's way....
did you order the entire seat harness? I ordered the air pump enclosed in the vinyl cover, valve unit, switch, and lumbar pad. Power under the seat. I made my own harness.

BMW does like X-using parts.
but I do not know for sure.
my original harness in the seat did have wiring for the seat heaters but nothing for lumbar. You would need a connector on the valve body, switch, and pump. Then integrate this into the power of the seat. I believe the entire seat harness is 100 dollars. I am not sure if there is a retrofit harness available having the lumbar function only.

Yes, my back hurts when I drive for long distances. I have the standard seats in my 540i and I definitely need lumbar support.

I had awesome seats on my 93 SSEi, the lumbar was not standard; however the 18-way seats had 3 different lumbar bags in them and moving side bolsters. Best seats I ever had. I think there were a couple of Pontiac models that had those seats.

I was only aware that Pontiac put either 6-way (adjustments on door) and 12-way (adjustments on console) power seats into their early to mid-90s bonnevilles. You sure they were '18-way'?
In fact, they were a popular mod for us Impala SS guys since the light gray versions were a perfect match to the SS interior. In fact, I had a set of 'bonnys' in my '96 SS.
