This comprehensive guide will walk you through the common causes of headlight problems in the 2015 GLA 240, how to diagnose the issue, and the steps to fix it yourself. We’ll also provide answers to frequently asked questions to help you get your headlights shining bright again.
Common Causes of Headlight Problems in the 2015 Mercedes GLA 240
There are several reasons why your GLA 240’s headlights might be malfunctioning. Let’s take a look at the most frequent culprits:
- Blown Fuse: A blown fuse is one of the simplest and most common causes of headlight failure. Check your owner’s manual to locate the headlight fuse and inspect it for any signs of damage.
- Burned-Out Bulb: Headlight bulbs have a limited lifespan and will eventually burn out. If only one headlight is out, a burned-out bulb is the likely culprit.
- Faulty Headlight Assembly: Sometimes, the problem might lie with the entire headlight assembly itself. This could be due to a wiring issue, a faulty ballast (for HID headlights), or damage to the assembly from impact or moisture.
- Software Glitches: Modern cars like the GLA 240 are heavily reliant on software, and occasionally, glitches can occur that affect the headlights.

Identifying the Problem
Before you start fixing your headlights, it’s crucial to identify the root cause. Here’s how you can diagnose the problem:
- Check the Fuse: Refer to your owner’s manual for the location of the headlight fuse(s) and inspect them. If the fuse is blown, it will need to be replaced.
- Inspect the Bulbs: If the fuse is intact, visually inspect the headlight bulbs for any signs of burning or damage. If you suspect a bulb is blown, try replacing it with a new one.
- Examine the Headlight Assembly: Carefully check the headlight assembly for any signs of damage, moisture, or loose connections.
- Use a Diagnostic Tool: For software-related issues, you’ll need a compatible OBD-II scanner to read and diagnose fault codes related to the headlights. Cardiagtech offers a range of diagnostic tools suitable for Mercedes vehicles, which can help pinpoint the exact cause of software-related headlight problems.
