The designation of the transfer box is ATC13-1. The ATC13-1 is a standard transfer box and was first used in the G12.

One special feature of this transfer box is the Efficiency Mode introduced in the G12, which leads to a reduction of the splash losses and to reduce fuel savings. It was possible to adopt the measures introduced in G12 for the G30.

Oil change on the transfer box

The oil filling of the transfer box is designed for the entire unit service life. This corresponds to a mileage of approximately 150,000 km / 92,000 miles. A fault code entry with an oil change recommendation for the transfer box is stored when this mileage is exceeded.

Part number 83 30 0 493 337

The transfer box does not have an oil drain plug. The oil filling to be renewed must be drawn off using a hand pump via the opening of the oil filler plug.


In order to ensure that the entire oil filling has been exchanged, the oil sump must remain open for the duration of extraction and filling.

The Service employee can move the oil sump to the open position by means of the "Service function > Transfer box VTG > Oil change" in the BMW diagnosis system ISTA.

Refer to the currently valid repair instructions for the exact procedure.
