Absolutely incredible ... Electric Water Heater working all the time very good but consumes electricity from the battery when the car is turned off. If I don't drive the car two or three days all the power from the battery are empty?! Battery is new and I take my bmw to Electric handyman for cars and he detect that when Electric Water Heater is plug off car don't consume the power from the battery?!
Does anyone now how to resolve my problem (changing the whole part is too expensive)? Can I change the wires from Electric Water Heater?

part number on module: 64126918806

Thank you for your answer ... I will try to explain everything.

1. BMW e46 320D year of production 2004.
2. I write this code: NE512P 64.12-6918806
3. Battery charged fully 3. times and I take battery to servis and they told (after they test it) that battery is ok.
4. Electric car servis in one of the best in my town and I took my car to that servis and need all day to find out what component drain out my battery. In the end they found out (when they switch off electric water heater / picture in attach) that electric water heater make that problem. But electric water heater work just fine,only that he drain out every time my battery when car is not driving for two days.
5. Can I somehow put new wiring to the battery or I can put some switch relay that will turn on when I put ignition key?
