a fi mi bimma

Mw DSC & Brake light came on while driving yesterday(both lights yellow).
Both lights are now on permanently.

Did some research in the BMW TIS that I have & it is saying that the DSC has a fault(at least that is what I interpret).

Has this happend to anyone before & does anyone know how to correct this without taking it to the dealer(want to leave that as a last resort).

If anyone has any advice I would greatly appreciate it.
