Are you using M3 cluster ? from what i remember you can only use OIL TEMP if you have an M3 Cluster, as the normal cluster dont have the OIL TEMP, instead it has the "ecometer", also have you installed the LEDs on the cluster if you are using the normal cluster ?

Found a bit more of information

To make the warmup lights and shiftlights work, you will have to flash your MS43 with an unlocked software so you can change the code in that.

The MS43 Wiki is the best site to get more information about this. There are also some good youtube videos about how to flash the MS43.
BE CAREFUL and ALWAYS make backups while doing this. Also charge the car battery and the laptop battery. If the process fails you can buy a new MS43.


After the MS43 is unlocked, you can access the MS43 with the MS4X-Flasher and copy the binary data (Full binary 512kb required for LED Mod).

Download the M Cluster LED Mod from the MS43 Wiki.

Open the binary file in TunerPro and also open the LED Mod definition file (Included in the M Cluster LED Mod downloaded).
There will be an entry in the list on the left side of TunerPro which is called "Patch". Apply this to your 512 kb binary by double clicking.
After that you can save the binary and flash it onto your car using the MS4X-Flasher.

Turn the ignition off, wait 10 seconds and put the ignition on.
Red and yellow leds will allways light up for the 6500 rev limit.
The warmup lights will work with the oil temperature sensor and shiftlights will appear at 6000+ rpm.

I can add pictures and go more into detail. I flashed my MS43 a year ago for the exhaust pop mod.
Last week i added the LED patch and it all worked fine.

For help just contact me :D

if that does work, might be worth to create a DIY guide for it, as im pretty sure with correct instructions many more of us would do the same.
