I was not able to get it working as I wanted and eventually I got rid of that cluster in favor of dashboard displayed on my tablet over the local network.

Hey I have got the same problems with my E36 cluster. Is there any new solution for that.

I ve got the cluster form 1999. The only thing that works is the spedometer. Only thing i would like to work is the RPM. Can someone help?

Issue must be somewhere else. I did check various years' pinouts using great resources at http://wedophones.com/BMWManualsLead.htm and it seems that every pre-00s model uses the same pin, pin 20 for "crankshaft rpm speed signal td" which comes from "engine control module (dme)" Also same pins for gnd and +12V on that socket.

Do you have any more suggestions what sort of stuff should I check?

Only thing I can think of mate, is that the wiring is different on the compact version (the one with no MPG gauge). I've not personally tested a Compact cluster. I'd recommend having a browse on Google for a wiring diagram that best matches your cluster.

It seems likely, given that you have some gauges functional (meaning that your GND connections to the arduino are fine)

Let me know how you get on ;)

It is from 318i, 4 cyl. year is unknown (possibly 92-96 give or take) to me. It was EU version, compact. It has few labels:

BMW 62.11-6 903 030

HW 0.3, SW 10 CAN 03 AI 65

VDO 110.008.831/043 A

It has black plastic cover on the rear with VDO logo and number 88311221 43250 (tho don't quote me on that last number, it is quite unreadable).

Have you got any specific information about the model year and car model that it came from? I've seen some people use clusters from a compact car, they may have different wiring. The cluster I used was from a 318i 97 iirec

Yes, native simhub, no custom protocol, using with single arduino option. 115200 baud rate running at 60 fps.

Are you using the native SimHub support, with the arduino setup tool in My Hardware to enable the gauges. Custom protocol isn't needed for gauge support anymore, my E36 sim video now wrongly demonstrates how to set it up (as it's outdated).

Oh I am sorry I forgot. I am using an Arduino UNO (some Funduino clone board, but so far 100% compatible with all the stuff and shields I did use it with to date).

Hi Coyote!

You didn't mention what model of Arduino you are using. The wiring diagram I've made for the wiki is intended for use with an Uno or Nano (same chip).
