Volkswagen Daytime Running Lights: Why Do They Turn Off?

As a Volkswagen technician, I have seen many cases of daytime running lights (DRLs) turning off. This can be a frustrating and inconvenient issue for drivers, as it can make it difficult to see their vehicle in traffic. In this guide, I will walk you through the steps to troubleshoot and potentially resolve the issue. I will also provide some tips on how to prevent DRLs from turning off in the future.

Why Volkswagen Daytime Running Lights Turn Off

Burnt-out Daytime Running Light Bulbs

The most common reason for daytime running lights to turn off is a burnt-out bulb. Daytime running lights are typically equipped with either halogen or LED bulbs. Halogen bulbs are more susceptible to burning out than LED bulbs, but both types of bulbs can eventually fail.

Wiring Problems

Another common cause of daytime running lights turning off is a wiring problem. The daytime running light circuit can be damaged by a number of things, including:

A short circuit
A loose connection
A damaged wire

Faulty Daytime Running Light Switch

The daytime running light switch is a small switch that is located in the vehicle’s interior. This switch is responsible for turning the daytime running lights on and off. If the switch is faulty, it can cause the daytime running lights to turn off.

Faulty Daytime Running Light Control Module

The daytime running light control module is a computer that is responsible for controlling the daytime running lights. If the control module is faulty, it can cause the daytime running lights to turn off.

How to Troubleshoot: Volkswagen Daytime Running Lights Turn Off

Daytime running lights (DRLs) are a safety feature that helps to make your vehicle more visible to other drivers during the day. However, if your Volkswagen’s DRLs turn off, it can be a cause for concern. There are a few possible causes for this problem, and you can usually troubleshoot it yourself with a few simple steps.

Possible Causes

There are a few possible causes for your Volkswagen’s DRLs turning off. These include:

A blown fuse:

The most common cause of DRL problems is a blown fuse. To check the fuse, locate the fuse box in your vehicle’s engine compartment. The fuse box will be labeled with a diagram of the fuses, and you can use this diagram to find the fuse that controls the DRLs. Once you have located the fuse, remove it from the fuse box and inspect it for damage. If the fuse is blown, you will need to replace it with a new fuse of the same amperage.

A faulty relay:

Another possible cause of DRL problems is a faulty relay. The relay is a small electrical switch that controls the flow of electricity to the DRLs. To check the relay, locate it in the fuse box. Once you have located the relay, remove it from the fuse box and inspect it for damage. If the relay is faulty, you will need to replace it with a new relay.

A wiring problem:

A wiring problem can also cause DRL problems. To check for a wiring problem, you will need to inspect the wiring harness that connects the DRLs to the vehicle’s electrical system. Look for any damaged or frayed wires. If you find a damaged wire, you will need to repair or replace it.

A problem with the DRLs themselves:

Finally, it is also possible that the DRLs themselves are faulty. To check for a problem with the DRLs, you will need to remove them from the vehicle and inspect them for damage. If the DRLs are damaged, you will need to replace them.

Troubleshooting Steps

To troubleshoot your Volkswagen’s DRL problems, follow these steps:

1. Check the fuse:

First, check the fuse that controls the DRLs. To do this, locate the fuse box in your vehicle’s engine compartment. The fuse box will be labeled with a diagram of the fuses, and you can use this diagram to find the fuse that controls the DRLs. Once you have located the fuse, remove it from the fuse box and inspect it for damage. If the fuse is blown, you will need to replace it with a new fuse of the same amperage.

2. Check the relay:

Next, check the relay that controls the DRLs. To do this, locate the relay in the fuse box. Once you have located the relay, remove it from the fuse box and inspect it for damage. If the relay is faulty, you will need to replace it with a new relay.3. Inspect the wiring harness:

If the fuse and relay are both good, then you will need to inspect the wiring harness that connects the DRLs to the vehicle’s electrical system. Look for any damaged or frayed wires. If you find a damaged wire, you will need to repair or replace it.

4. Check the DRLs themselves:

If the fuse, relay, and wiring harness are all good, then you will need to check the DRLs themselves. To do this, remove the DRLs from the vehicle and inspect them for damage. If the DRLs are damaged, you will need to replace them.

Conclusion

Troubleshooting Volkswagen DRL problems can be a simple process if you follow the steps outlined in this article. By checking the fuse, relay, wiring harness, and DRLs themselves, you can quickly identify and fix the problem.
