It does happen: For instance, on the 140/220 chassis, the transmission electrical connector at the transmission has a seal that fails, and transmission fluid migrates along the wires (being pulled by the electrical current) until is reaches the transmission control module.
Was hard to believe at first, until I ran into a harsh shifting/erratic idle concern on a 1998 S420, and a harsh shift on a 2002 S500.
This applies to the engine oil also. It may not cause problems now, but I would recommend removing the control unit, opening it up (it will not hurt it) and cleaning it out with brake cleaner "parts wash" (it dries fast).
Happy Benzing!!!
