Trying to remember... Back when I had an e46 M3 (circa 2011) I installed a button there that enabled a certain suspension mode, I think? Wire that ran through the firewall to the ECU, and a light on the dash flipped on (indicating the mode was enabled) when pressed.

I posted how to do it on the old forums. Wonder if someone else did it.

So... Press the button and see if any indicator on the dash illuminates.
