I have a question about the setup for the charging system for the older 2003 X5. I have read some posts on different BMW models where the battery light on the instrument cluster is actually part of the charging system, so if the bulb is blown the alternator doesn't charge the battery. I took my rebuilt alternator to Advance auto parts and they tested and said it was good.

Does anyone know if this is the case for the X5? Second is there a thread on how to replace the bulbs on the instrument cluster someone is aware of.

Thanks
