Can anyone help solve the mystery of the low beam warning light on my 323i? The in-dash warning light for the front left light stays on constantly, even though there is nothing wrong with the light. Is there a quick fix (other than taking to a specialist) that doesn't involve any complex DIY engineering?

If it seems to be operating properly, how have you determined specifically that it is your low beam, that is causing the left front warning?

If you have checked all of your left front bulbs, including side indicator for function, I would next check the socket interface for possible corrosion first. The vehicle sends out a brief electrical pulse across the bulbs when first powered up to verify continuity across the filament. If there is additional resistance, from poor contact or damaged wiring or sockets, you can have a situation when the bulb will still light but the initial circuit check will fail. Off-spec bulbs can also result in the same. Is this a new problem that developed or has it been on since you acquired the vehicle?
