This instructable will uncover the option to add the BMW sports driving mode on all 2006 BMW 530i's with the E60 chassis. The sports driving mode was never offered for this particular model, even though they classify this car model as a sport model, you couldn't get the actual sport driving mode. How this works, and how it's possible, is because this model and other E60 chassis BMW's use the same engines, with the same electronics. Since different models use the same chassis, a lot of the options will be the same. Certain options are not offered on lower end models, even though the capabilities are there. I have only done this hack on a 2006 BMW 530i with the E60 chassis, but I believe this button can be added to any E60 chassis, in the 5series models, in the "I" class.
Pry Tool or flathead screwdriver

Momentary button/switch of your choice
18 to 22 gauge wire
Quick Scope of Work:
What we are going to be doing is actually very simple. We will be taking the dash apart to get to a harness that is connected to the ecu , once we have the dash/ecu out and the back exposed we will be adding two pins to a harness, which will be connected to a momentary switch or button of your choice. After the two wires are inserted in the harness you need to figure out where you want to mount your button/switch. Run wires and button to the desired spot, and mount switch. Put everything back together in reverse order as you took it apart. Now to make sure it works, start your car, push the button you installed and make sure the word sport comes on in the info center in between your gauges.
And there you have it.
Step 1: Remove Dash Piece
Start on the right hand side of the center strip piece. Use a pry tool or a flat head screw driver and insert it in between the strip and the dash and pry it away from the dash, towards yourself. It might take a little more force to get it started than you think. Once you broke the center piece free on that side, work your way to the other side of the strip, pulling the piece towards you. When you feel a section breaking loose move down some on the strip. Once you have broken the whole piece loose, pull it out at an upward angle, like your pointing the vents upward. Once you have the piece out, there is going to be a wire harness you need to unhook.
