I ordered a set of 4 Cam position sensor extensions from ZZ. (Yes there is a cam position sensor only set available: 2011-20 Mercedes Benz 4.7L Camshaft Position Sensor 3 Pin Harness Extension M278). The connector for the sensor end is identical to the original. The harness end connector has additional bits to connect to its original intended application, but fits perfectly, including weather seal. Wagon starts and runs fine...no codes thrown. Yay!

Along with the pigtails, couldn't a silicone be used as well in the connectors? Or has there been evidence it get by that as well?
Oil wicks along the metal male-female contacts, which are in intimate physical contact. It then wicks along the harness-side contact along the wire and into the insulation, and from there it goes anywhere it can go.
So, no. Silicone in the connector is not a solution. New sensors and magnets are the solution to the root cause, which is failed magnets and sensors. Replacement harness and ECU are sometimes required if the saturation is sigificant enough.
