From the project
Reverse engineering and improving the BMW E30 service indicator board
I'm currently working on a little project for all the early model E30 drivers with SI board trouble from leaky batteries or mechanical damage.
I am reverse engineering the early model SI board, in my case the VDO version (VDO and motometer are interchangeable)
This initial version is a 1:1 copy of the original design. The main microcontroller, the crystal oscillator and the large pin header need to be desoldered and taken over to the new board, but all other components are readily available and stocked parts.
