What's up with these two codes?

I've got a 09 BMW 328 with almost 74k miles on it. I starting the car to drive home from work this evening and got a yellow brake light and the car on a lift symbol in yellow.

I pulled out my scan tool (I keep it in the car now) and got codes 6EC4 steering angle sensor adjustment and 5F11 which is for the rear brake pad sensor.

What I don't get is the front brakes are 1.5 year old. My indy put new pads, rotors, and a sensor. The car has 71k miles on it. It has close to 74k on it right now. I highly doubt the front pads are gone.

Rear brake job (pads, rotors, and sensor) the PO had them done at his indy in 2015 at 55k miles. I visually checked the rear pads and they look fine. Brake fluid is also nice, clean, and at the max level. So, why the brake light? Maybe a faulty sensor? Also, the steering angle sensor kinda through me off.

I don't brake hard for the pads to wear out after 20k miles

rear pad wear sensor shorted either from wear or wiring somehow broke internally. complete the circuit just by cutting and splicing the two wires back together and see if the light turns off.

ignore angle sensor code unless you’re getting ABS/DSC warnings
 
The brake wear sensor system on newer BMWs isn't as cut and dry as cutting the sensor to turn the light on. When you reset the system, the computer has an algorithm built in that calculates the remaining percentage of brake pad life, likely so you could look in the maintenance minder and see it with a scan tool. If the sensor wasn't cut when the original brake service was done at 55k, and if the system wasn't reset to 100%, that percentage will continue counting down to zero regardless of whether the sensor was cut or not. If the sensor isn't cut now, you should be able to reset the system with a scan tool and be fine.
 
Pads are rotors look fine to me. I'm gonna reset the light with a scan tool. If it comes back, I'll go ahead and replace the sensor.
