My brake light is not working

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. So sorry to hear you're having trouble with your vehicle. If your brake lights aren't working on your E430, a common cause could be a blown fuse, a faulty brake light switch, or burned-out bulbs. Since the issue just started, it's worth checking these components first. Ensure the bulbs are in good condition and the brake light fuse is intact. If these parts are all fine, the brake switch near the brake pedal might need replacing. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
