Has anyone got any ideas where I might be able to source an instrument cluster for my J reg 325I? Or has any one got any schematics on what parts to replace as my rev counter and mpg have packed up. Also it has affected my trip computer which is not working. Any help would be appreciated.

I remember reading about someone else with a similar problem, have you tried searching? IIRC a quick punch on the dashboard made it spring back into life hinting at a loose connection.
