SBC S brake problem

About a month ago the brakes failed totally on my 2004 Merc E320 automatic. I got a red warning light come up saying something like "SBC brakes fault, visit workshop". I was absolutely terrified and feel lucky to still be alive. I had to get towed to the dealers and they had my car for 3/4/days and said they had replaced the SBC unit and it was safe to drive. About a week later the same red SBC warning came on again so I sent it back to the dealer. This time they told me it was a brake light switch that wasn't working and that all was now fixed and safe to drive. Yesterday, I was driving along when suddenly it seemed as if the brakes were being applied even though I wasn't braking, so I pulled over to the side of the road and could see there was SBC S on the dial again but on a white background this time. I rang the dealer immediately and they told me not to drive it any further and to get it sent back to them again. They ran some diagnostics but said they could find no faults with the car and didn't seem to know what was wrong. I am really really scared to drive this car anymore. What is the problem? What can I do?

Mercedes discontinued the SBC system in 2006, that speaks volumes.

Look in the E class forums, I read somewhere the warranty might have been extended.

... and this important discussion continues.
