Your Audi’s tail light is as important as every other light when it comes to driving at night or at times when there is poor visibility. If your Audi Q3’s tail lights are not working properly, we highly recommend you fix the problem to enhance safety while on the road as well as to avoid possible fines. Here’s a comprehensive guide on how to fix defective tail lights on your Audi Q3.
How To Fix Faulty Tail Lights
- Identify the Problem: Before you can fix a problem, you must first be able to recognize the problem when you see it. The first symptom that Audi owners should look for is if the tail lights do not come on when the headlamps are switched on. Another way to identify a problem is when the lights are dim or blinking — this could mean that a connection is loose or the bulb is burnt out. Most modern cars have warning lights on the dashboard to alert you when there is a problem with the lighting system, so be on the lookout for this warning.
- Check Bulbs: Damaged or non-functional bulbs are often the primary reason for poor tail lights. To check and replace the bulbs, retract the tail light assembly which is usually found in the trunk compartment. Depending on the variant of your Audi Q3, you may have to pull a panel or a cover to get to the bulbs. Check the bulbs for any signs of damage or burnout, if there are any, replace them. A bulb that is no longer working will usually have a cracked filament or will appear to be covered in a dark haze. If a bulb is dead, then change it with a new one, make sure to use the correct type of bulb for your Audi Q3 as mentioned in your owner’s manual.
- Check Fuses: If the bulbs are in good condition, the next thing to look for are the fuses. If the fuse is blown then the light will not come on. The location of the fuse box will typically be in the engine bay or under the dashboard inside the car. Locate the fuse for the tail lights in your car’s owner’s manual to determine the correct fuse for your car. Pull the fuse and see if it has blown. The broken metal strip inside will indicate that it is a blown fuse. If the fuse is blown, replace it with a new one of the same amperage as the blown one.
- Check Wiring: If both the bulbs and fuses are intact, then the problem is likely with the wiring. Sometimes the problems with the tail lights can be caused by improperly installed wires. Inspect the wires connected to the tail light assembly to see whether they are well connected or damaged. If you discover any wiring problem you have to fix it immediately.
- Checking Tail Light Assembly: In some cases, the issue may not be with the wiring but with the tail light assembly itself. Water or dust may infiltrate the assembly and cause electrical problems. Take out the assembly and ensure that it does not have any traces of moisture or dirt within it. If there is any dampness or dirt, you need to clean the inside of the assembly and allow it to dry before proceeding to reassemble it.
Preventive Measures
When you take your Audi Q3 for a routine check, tell your mechanic to inspect the lights. Make sure that the tail lights are clean and that no water gets inside the assembly. Regular maintenance can reduce electrical problems that may arise from dirt and water intrusion.
