Lumbar adjustment (option 537)?

I have it, yet I don't know how to adjust the lumbar. There is no lever or any electric buttons that I can find. What am I missing? The back of my seat is pumped up all the way at this point. Thanks for NOT telling me to RTFM!

do you have the full power seats? if o there is a 4 way adjustment ****...at the rear of the seat adjustment panel...i think to increase the air push forward or up, decrease is down and to the rear...you should hear the air pump make noise when you do this..if not maybe a fuse?

Yeah, I have the comfort seats with lumbar driver's seat. I never thought of pushing the lever UP or DOWN. I'll have to give that a try! Thanks!

Newport- I have option 537 listed, with full power seats but I don't see a lumbar adjustment on the seat. I have a round black plug near the 4-way adjuster.

Yeah, I have this circular plug too. I thought Newport meant the lever that adjusts the seatback forward or back also goes up or down to inflate or deflate the lumbar area? If not, I am lost again!

I assume if the option number is listed, Porsche didn't forget to install a lumbar switch, right?

Here are my seats, and behind the seat back adjuster there is a 4 way switch..that controls the lumbar support...if you dont have that, maybe your seats were swapped?

Wonder why both of us have the option listed, but a blank plug where the switch should be?

maybe the seats were swapped...do you have sport seats or GT3 seats?

Not that I know of! Just the standard seats, in supple leather, with a really hard lumbar area.

I have the same option listed on my 2000 and the same plug/cover with no apparent lumbar control. Standard seats with memory, I'm pretty sure they're original to the car.

Supple leather, memory seat, not swapped...

Maybe Porsche owes us all a lumbar control??

Hey Newport - what option codes do you have, since your seat has the lumbar switch??

I have wondered the same. The Porsche Red Book has option 513 as lumbar support, passenger, adjustable. There is no mention of 537. My car has 513 and 537, however, I only have adjustable lumbar on the passenger side and the same cap on the driver side, which to me seemed strange. This is what I can get on the option decoder: Code Option Description 513 Lumbar support - right seat 513 Driver's Seat Lumbar Support 537 Left seat with positrol and lumbar

Me too.....

This is directly from the 996 PET: 513 Back support - right seat 537 Seating position control for comfort seat, Left 538 Seating position control for comfort seat, Right 586 Back support - left seat So the way I read this is that if you have 537 (and maybe 538) you have electric seat adjustments for the seat bottom (raise/lower/tilt and forward/back) and seat back control (tilt forward/recline). You would need to have option code 586 to have lumbar control on the driver's seat. I am betting that Newport996 has option 586 on his sticker (if the seats he showed in his pic are the original seats).

Thanks Tim, you are correct, that makes sense. What does not make sense to me is why there are so many cars with lumber support on the passenger side only.

Just a "wild guess" here, but maybe Porsche over estimated the demand for Europe buyers wanting lumbar for their Driver's side (right side) and just stuck them in North America cars. I know, I know, it sounds crazy, but it IS possible! Other thatn that, I have no idea why there are so many cars with lumber support on the passenger side only.

So, the famous Porsche Options Decoder site is WRONG?

Looks like I have 586 and 588...so maybe thats driver and passenger lumbar supports?

Newport - There is not a 588 listed in the PET. Also, I can't find a 588 on any of the other Option Code sources either. BTW - the passenger lumbar support is option code 513.

Hmmm....I'll look again..I could sware it was 588...there was a wrinkle on it so maybe it was 586, but what was the other code than? Hmmm....

It may be 588 on your sticker, but I can't find an associated option to match it. I know that there have been a few "mystery" (i.e. undocumented from Porsche)codes that some owers have posted.

Thats a real shame for you guys as I LOVE the controllable lumbar adjustment

Boooo!

+1 Thats why I have not switched to sport seats....i am trying to figure out how to custom make full power sport seats with the lumbar support.....I wonder if I got the seat backs, used my seat bottoms, and put the lumbar stuff in from my seats backs into the sport seat seat back shells, then had the whole seat reupholstered to match....sounds expensive, but I could get my sport seats, and keep the full power functionality....and the comfort of the lumbar supports....hmmm....
