On the Mercedes ml320 you should be able to ground the o2 sensor to the body of the car. Just find an unpainted section and stick its ground wire on. If this does not work, try adding an isolation capacitor between the grounding pin and chassis as well. If this still doesn't work, got to the dealer.

How do you earth a computer?

Most home or commercial building wiring uses 3 prong power outlets. One of the pins on a plug SHOULD be the ground/earth wire.If the power cable was created properly, the computer should be properly grounded (earthed) when it is connected to the main power through that plug...HOWEVERIf there is any doubt as to whether your power outlet has a built in ground connection, you can connect a single (12 GA or 14 GA) wire to an iron or copper pipe in the home or drive a grounding rod into the ground outside the home and connect the wire to that. Run the wire to the computer and place a crimp-on lug to the end of the wire, then connect it to the computer chassis using one of the screws on the back of the computer.
