You may have a ground wiring fault. This is common to E46s and BMW has even issued a recall. The problem is, the grounding is not sufficient, which overheats and degrades the electrical connector over time. Ultimately the connection goes bad and gives you a "bulb out" warning on the dashboard.

Unplug the connector to the light housing and inspect for corrosion or melting of the connector. If you see any, bring it to the dealer for a free fix. If you like to DIY, there are plenty of guides out there. I followed this one:
