Transmission Oil Temperature Sensor
The transmission oil sump temperature is sensed by a temperature-dependent resistor which is soldered in the transmission wire harness.
The transmission oil sump temperature can be displayed with a scan tool.

Oil Level Measurement
The permissible minimum and maximum transmission oil level is indicated with BMW MoDIC.
This level is greatly dependent on the transmission oil temperature and is indicated corresponding to the table above.

The oil level should be measured as shown with the engine idling in position P on the dipstick.
