I have a M52B28 and installed an OBC from Germany. I also have installed an instrument cluster from a 6 cylinder. The cluster has no effect on the OBC. Both take signal from the same wire. The cluster has an mpg gauge which looks fairly accurate. The OBC is way off.
Unfortunately its hard to find OBC's from 323ti's or 6 cylinder Z3's in the UK. If anyone finds a solution for this problem please let us know.
