I've read several forums about replacing the battery in the back of the instrument clusters but I'm sure they run several gauges within the cluster. I'm having an issue where none of my Service Interval Lights (the maintenance oil light) are on -- the little red, yellow, green bar. I'm new to e30's but I imagine that the lights aren't getting power or a solid state board is out.
