BMW 5 Series G30 G31 and LED Headlights

One of the standard features of the G30 and G31 models is their state-of-the-art LED lighting technology. From adaptive LED headlights to crisp Daytime Running Lights (DRLs), BMW has taken lighting technology to another level and offers ample benefits. DRL’s improve safety and visibility, making sure your BMW is seen clearly in all lighting conditions. 

However, like any electrical component, these headlights can deteriorate under constant use and can develop issues over time, and when they do, your dashboard might show you a warning message. This makes it essential for you to replace your LED lights for safe driving. If your headlight is misaligned or needs a replacement, your vehicle will notify you through warning messages every time you start your car. Read on to resolve the issue. 

Common Warning Messages That You’ll Observe 

Like every other automobile, light maintenance work is required to ensure smooth functioning. One area that requires special attention is the headlights. 

Knowing the common warning messages and signs of faulty headlights can help you address the problem quickly and effectively. Here are some common messages that may indicate an issue with your LED headlights:

  • Side/daytime lights failure
  • Daytime/Parking lamp malfunction
  • Side light front and daytime driving lights failure
  • Luz posicion/luz diurna estropeadas
  • Luz de posicion delantera y luz diurna estropeadas
  • Parkeringsljus fram och varselljus defekta

These messages indicate that your DRL module might be failing or has already stopped working, leading to a loss of functionality in your front-side lights or DRLs.

Why Do These Lights Fail? 

Your headlights may fail for several reasons, whether external damage or hitting a curb, leading to misalignment. The reasons are endless. Understanding why your LED headlights have failed can help you apply the right methods to resume safe driving. Some of the most common reasons that your headlights may have failed are:

  • End of Lifespan: LED headlights are designed to be energy-efficient and durable in the BMW 5 Series, but like all electronic components, LED modules have a finite lifespan. Over time, heat and prolonged use can wear them down, due to which might lead to reduced brightness or a total failure to operate. If this is the case, it’s time to replace your headlights. 
  • External Damage: External factors like road debris, moisture intrusion, or electrical surges can damage the LED DRL module, causing it to malfunction or stop working entirely. Look for visible cracks on the headlights; if you notice any, know that it’s time for a headlight replacement. 

How to Identify a Faulty Part / Symptoms

When your LED DRL module starts failing, you’ll likely notice one or more of these symptoms before the lights stop working completely:

  • A warning message related to Side/Daytime Lights Failure appears on the dashboard.
  • Halo rings (Angel eyes) start changing colour from cool white to a yellowish hue. 
  • The brightness of the DRLs gradually fades or becomes inconsistent.
  • The DRLs stop working completely, leaving you with no daytime running lights.

How To Fix The Issue

Through assessment, if you have determined that your vehicle needs a headlight replacement, the next step is pretty straightforward. There is no need for complex diagnostics. If you encounter any of these issues, all you need to do is:

  • Buy a new LED DRL module and replace the faulty one. This will restore the DRLs to their original brightness and functionality.
  • No coding or additional diagnostics are required. All you need to do is just swap out the module, and you’re good to go.
