"Service Break Visit Workshop"

I recently had the same message and replacing the brake light switch didn't resolve the problem. It turned out to be the faulty SBC pressure reservoir that's attatched directly to the SBC hydraulic unit. I have seen some people call it an SBC accumulator as well. The dealership got code #C2131 and it was a US$1400 repair. A local independent MB only mechanic didn't want to touch it...too much liability he said...so a dealership repair job was the only option I felt comfortable with.
Sounds like the next step for you should be to get the code read by a DAS/Xentry diagnostic. Good luck....and sorry about that!
