I suspect KrisM3 meant the side bolsters which are part of the Sprt Package, not lumbar.
My car is a 2010, US spec 135i. I did not order the lumbar support. I ordered a car with manual seats and it came with that. There is a little dip switch at the drivers front corner of the seat that inflates or deflates the lumbar cushion for your back.
I did not want a lot of options for my car... I only order (full)M-sport, 6FL/USB port, metallic paint, heated seats, 6MT, and leather seats.
On the EU/German spec models you can order every ala cart. But you pay dearly for every little option!
