I bought a 2006 330i a couple months ago, with no brake warning lights. The red warning service light recently came on with the brake signal saying to get them checked immediately. I know for a fact that the sensors or something is at fault because the brake pads are practically new. I was at a mechanic's the other day with another car on a non-related thing and I casually mentioned to him what I believed to be a faulty brakepad sensor. He told me he'd take a look, but strongly warned me NOT to reset the service computer (which I thought about doing with the Carly coding app). He also told me it's really easy and quick to fix faulty sensors and that I could probably manage doing it myself.
Assuming it is in fact the brake pad sensor(s), can someone guide me on how to make this brake light warning go away? Can I just do some simple coding or computer reset (and why would a mechanic care if I do this)? Or do I have to replace the brake pad sensor, and then and only then can I do the reset (or will the computer detect the new sensor and coding/resetting will not be necessary)? If I do have to replace the brake pad sensor, how do I tell which one to replace? Do/should I need to replace all of them?
Thank you!

What is going on with my brake warning light?
