Thank you for your reply.
I have read the manual and I think the E36 is not the proper instrument cluster for my demonstration. However I have found a lot of information about the E46 instrument cluster and I am sure I can control it using the CAN network. I have information concerning the connector of this instrument cluster (http://www.bmwgm5.com/E46_IKE_Connections.htm
and I know which instrument I can control with the CAN network (http://www.bmwtech.ru/pdf/e46/STO34%...Internet-1.pdf
But unfortunately, I do not know yet what are the CAN ID for each instruments and what data has to be sent to control them.
Does anybody have information about it ?
