Troubleshooting brake warning lights

[806N4NN0]

I have recently purchased a 2007 R56.

I have two light that come on simultaneously. The brake light and the triangle with "!" within a circular arrow.

I've tried to attach a picture to this post.

I've replaced brake pads and rotors. I've also replaced the break wear sensors. These two lights still show up as soon as I begin driving.

Any thoughts on what it might be?

Could be a brake fluid flush reminder. It would be reset by the dealer-specific tool that they plug in to the OBD-2 port, if that's what it is.
