    Copper, aluminum or fiber (original on early models) is just fine.

    Looks like part 20 in the ETK is the part, a 14x18 washer.

    Going from memory here, the thermostat has two identical holes, one for the switch, and one is for a blanking plug which uses a washer.

    I would use a copper washer...

    It does not need to come from BMW....any decent auto parts store will have a variety of copper sealing washers. They are used for an endless array of things. Even hardware stores have them.

    Just measure the sensor so you know what size you need.
