Thanks for the reply. I replaced the O-ring with the official Mercedes part from the dealer, it's thick like the old one, and fits perfect. It goes in to a huge notch, and would be impossible to install wrong. That's why I'm thinking the fluid has to be finding another path, and the only thing I can come up with is something to do with that hex nut with the hole where the switch and it's O-ring goes in.
