It may be a broken "brake light switch" that many people had. On my 99 E430, the brake light switch got 4 pins. Your car's brake light switch got 6 pins that may explain why the central lock does not work. Cruise control should not work either when ABS... warning light is on. The switch is located above the brake pedal, you need to remove the cover to get to it. Go to the forum for your car model, search for "brake light switch" to find fixing details.
Dealer may charge $200 for part and labor. If you got the time, order the switch from autohausaz.com (~$15) then replace it yourself.
Credit should go to the member who posted the fix for the problem. He/she saved the MB world millions of bucks.
