I've had that a few times. If yellow DSC light and the yellow brake warning light are on it means that the DSC, DTC or DBC are defective. I manage to fix mine by jiggling the wires at the DSC unit and the brake master cylinder switches.
I've had the codes read when it happens to me and they come up as:

5E 20: PRESSURE SENSOR 1; ACCIDENT RECOGNITION

5E 24: PRESSURE SENSORS NOT PLAUSIBLE; PRESSURE SENSOR 1/2 NOT PLAUSIBLE

Go figure. :hmm:

Could have been the bumps in the rode that "jiggled" the wires. Didn't do anything and next car ignition they were gone. Should I be concerned? Or preventative tips? I am now using shifting down to slow down to save wear on the brakes but also feel that places wear on the transmission :|

Don't be silly and downshift to slow down and put strain on your transmission. It costs a lot more to repair a tranny then it does brakes. Be sensible.

Drive the car normally. I suspect one or both of the brake pressure sensors in the master cylinder might be sending (or not) some BS signal. I find it has been completely random and has happened to me about four times in two years of ownership.

Maybe I'll stop down shifting then. And just assume the sensors are sensing inaccurately. Thanks for now guys!
