It's unusual for both bulbs to stop working simultaneously, but it could happen in this case. Other potential causes for the taillights not functioning on your 2016 Audi Q3 may include a blown fuse or a damaged wire. The fuse is the more probable culprit, and it should be easily accessible in the interior fuse box for a quick check. On the other hand, inspecting the wiring could be more challenging; you'll need to follow it from where it connects to the lights on the chassis. Additionally, another factor to consider is a malfunctioning sensor in the Q3's tailgate, which surprisingly can also lead to the taillights not working.
My rear vehicle lights suddenly stopped functioning. The mechanics at the garage couldn't explain the issue. Two weeks later, with frosty December mornings setting in, my battery died. After having a new battery installed, oddly enough, the lights started working again unexpectedly. 🚗💡
In order to reset the brake lights or ABS sensor on a 2016 Audi Q3, you should disconnect the battery and press the brake pedal for 30 seconds. Neglecting to do so could lead to the ABS system malfunctioning, resulting in unreliable braking. If the brake light still doesn’t work after resetting, you may need to replace the bulb or repair the wiring.
