In my car series (W210) the brake light sockets are often to blame for a brake lamp failure indicator so that's why I suggested that. If those are O.K. as well as the bulbs, wires and fuses, then it's indeed time to look upstream. That's where I'd be lost though; hopefully someone else will chime in. If all else fails, look for the model-specific forum for your car and ask the other C32 owners.
