There are a number of exterior light bulbs around your BMW X3 that require maintenance. The front side marker /turn signal lights are located in the headlight and serviceable without removing the headlight.

X3 exterior bulbs are monitored by the Light Module (headlight switch, LM), which also monitors and controls instrument panel dimming.

Bulb monitoring by LM is done both cold and hot (unlit or lit). In cold monitoring, LM sends brief current pulses to unlit bulbs to measure their resistance. The pulses are too short to illuminate bulbs but serve the purpose of evaluating whether an individual bulb or bulb circuit is defective. In hot monitoring, LM measures the current to individual lit bulbs to determine overload or a break in the circuit.

Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Our vehicle may vary slightly from yours as models do change and evolve as they grow older. If something seems different, let us know and share your info to help other users.
