Oil temp/pressure gauge options?

My first bmw was a 328i and it's gauge cluster had oil temp, as well as a better set of 'sport' display gauges in the center display, and a HUD that my M235i lacks.

I find myself missing these features, especially as I prepare the car for tracking.

I'd really like to get oil pressure and/or temp on the stock cluster.

Open to getting a different cluster, not looking to stick more gauges in the car as I prefer the OE style look.

Anyone done this before?

For those interested I've found a few options. Haven't made my mind up which to go for.

https://www.insideperformance.de/en/...-f22-f23-1297/ - This option uses the CAN network to fish up all kinds of data for you

https://topgearsolutions.com/p3-gaug...og-vent-gauge/ - This option has a few presets but can display any variable 5v signal input, however, you need to wire up the inputs yourself

Then there is this bit about how to get your IC to display it using some menu shenanigans.

1. Start the engine (it may work with only ignition on, I have not tried it) and make sure you have all doors and boot closed. If one door is open, it will not work.

2. Press the odometer reset button and keep it pressed until the BC screen changes (at least 10'').

3. When the screen changes, release the button. It will display a menu with numbered options. To scroll to each option you have press once the ODO resete button.

4. Go to option No. 4 UNLOCK and then press the odo reset button for a few seconds. It will enter the menu of this option and it will ask you for the unlock code.

5. The unlock code is the sum of the last 5 digits of your VIN. For example if your VIN is E123456, then the unlock code will be the number 20.

6. Enter the unlock code by pressing the odo reset button so many times required (in our example 20 times), until the number of the unlock code is displayed on the screen. If you accidentaly press the button more times than the required, worry not, just keep pressing it until it starts from 0 again.

7. Once you enter the unlock code, press again the odo rest button for a few seconds, to go to the previous menu. Now, the full unlocked menu should be displayed.

8. Scroll through all the option. Option No. 8 ''Temperature'' displays the outside temp, oil temp and coolant temp. To enter this option just press for a few seconds the odo reset button.

In general,when you are inside the hidden menu, by pressing the odo reset button once, you scroll through the options. By pressing it for a few seconds you will either enter the menu displayed or go back to the previous menu, depending on which screen you are at.

Lastly there's this bad boy. But for 1k I don't think it fits into my 'budget racer' build idea. LED display in the steering wheel.

The p3 is the easiest option, works well without losing a whole air vent.

Yeah that's the one I'm leaning towards personally.

Cheers from Tacoma.
