Item 13 oil temperature sensor. (No water here to sense.)

There's also refernces to oil temp on the M57 - now I'm thinking i might really need to look more closely at an Android head unit - the reasons keep stacking up!

Pretty sure thats backwards - M54 it calculates oil temp from some other data (coolant temp, ambient temp, oil pressure). M62 and N62 have oil temp sensors

Translation of the German text is: -

With this module, you can call up the following information by pressing and holding the BC button on the turn signal lever:

- Display of the oil temperature

- Display of the cooling water temperature

- Display of the battery voltage

- Digital speed display

No additional sensor or sensor is required, as the oil temperature is determined by the thermal oil level sensor installed as standard on every vehicle!

NOTE for E39 and E38 models: Only for vehicles from year 09/1997 and high instrument cluster! (For vehicles prior to 09/1997, the thermal oil level sensor must be replaced so that the eCombi module works)

The installation is very simple: The module is only connected with 6 cables: 5 cables at the plug of the instrument cluster and one cable at the plug of the lamp module.

So does this mean that it is possible with the stock internals without installing another sensor or does it need something else. I am trying to install a gauge of some sort that is either a direct feed from the ecu or from the sensor.

Check your OBC hidden menu #16 - no oil temp, no oil temp sensor. :(

good to know. thanks
I've always thought anything ovre 9 in the hidden menu was gibberish really... I will have to see if 16 is operating for my N62B4.4

Checked mine today - as expected, it just says "-- ºC" - no oil temp sensor on the M57TU.

Checked mine too. No temp showing on my N62B44

On my 4.8is, oil temp is shown correctly both in the instrument cluster and #16 hidden menu.

However the IBUS-App neither shows oil temp nor oil fill level.
In INPA, I have checked the values of the thermal oil level sensor (LCM - F5 - scroll all the way down with arrow key).
Heating and cooling time is always zero, but the sensor seems to works fine.

How does the instrument cluster get the value for oil temperature?
Are these values also zero on your cars?
