BMW Cigarette Lighter Fuse Replacement: Full Guide

The cigarette lighter in your BMW serves as more than just a tool for lighting up. It’s also a handy power source for charging mobile devices or powering accessories. If your cigarette lighter stops working, it’s often due to a blown fuse. This article provides a step-by-step guide to replacing the fuse for your BMW’s cigarette lighter.

Materials Needed:

  • Owner’s Manual
  • Fuse Puller (or a pair of needle-nose pliers)
  • Replacement Fuse

Note: Before you start, ensure that the replacement fuse has the same amperage rating as the one you’re replacing.

Step 1: Locate the Fuse Box

In most BMW models, the fuse box is located on the passenger side footwell or under the glove box. In some models, there may be a secondary fuse box in the trunk. Refer to your owner’s manual for the exact location of your specific model.

Remember, these locations and fuse numbers are typical, but there may be variations depending on the specific trim levels, regional differences, or updates by BMW. Always refer to your owner’s manual for the most accurate and up-to-date information.

Step 2: Identify the Correct Fuse

Once you have located the fuse box, the next step is to find the fuse associated with the cigarette lighter. The lid of the fuse box usually has a diagram showing the location and purpose of each fuse. You can also find this information in your owner’s manual. In many BMWs, the cigarette lighter fuse is a 20A or 30A fuse.

Step 3: Remove the Old Fuse

Using a fuse puller or a pair of needle-nose pliers, gently remove the fuse associated with the cigarette lighter. Be sure to hold onto it tightly, as fuses can sometimes slip from your grip.

Step 4: Inspect the Fuse

Look at the wire inside the fuse. If it’s broken or burned, the fuse is blown and needs to be replaced. If the wire isn’t broken, the problem might lie elsewhere in the electrical system, and it’s best to consult a professional.

Step 5: Install the New Fuse

Take your new fuse and push it into the slot from which you removed the old one. It should fit snugly and sit flush with the other fuses.

Step 6: Test the Cigarette Lighter

After replacing the fuse, turn on your car and test the cigarette lighter. You can do this by plugging in a device and checking if it powers up. If it does, then the problem was indeed the fuse.

Conclusion

Replacing the cigarette lighter fuse in your BMW is a straightforward task that requires a little patience and care. Always ensure you replace a blown fuse with one that has the same amperage to avoid causing damage to the electrical system.

This guide should help you restore the functionality of your cigarette lighter, keeping your devices powered up during your journeys. However, if the cigarette lighter still doesn’t work after replacing the fuse, or if it keeps blowing fuses, it’s best to consult a professional as there may be a more serious electrical issue.
