Let’s say you’re about to take your Porsche Cayenne 92A facelift for a drive, but instead notice a warning message on your dashboard. On top of that, your DRLs don’t work anymore. This can be your car’s way of communicating about an issue that requires some much-needed attention.

In this guide, we’ll walk you through the warning errors, reasons as to what led to the error, and give you practical steps to address them. 

Daytime Running Lights on Your Porsche Cayenne 92A Facelift 

Introduced in 2010 and slightly larger than its predecessors, the Porsche Cayenne 92A facelift came with a range of features, including LED daytime running lights and Bi-Xenon headlights that use D3S bulbs. Both of these components are controlled by an LED module that is connected with sensors and monitors to detect and send signals to the ECU. 

If the module is faulty or the DRL fails to work, the Electric Computer Unit (ECU) will recognise the fault and relay it to the dashboard– a common symptom of a faulty DRL.  

Common Symptoms of Malfunctioning Daytime Running Lights 

Beyond a warning light, you may experience additional symptoms when there’s a malfunction with your daytime running lights. Some of them are:

  • Daytime running lights don’t work: If the LED module fails to work, there’s a chance that either one or both of the daytime running lights will work. In some cases, both of the DRLs will fail to work due to a corroded LED module.  
  • Warning messages on dashboard: Another issue you can face is warning messages like “Daytime Running Lights Malfunction” and “Right/Left DRL Malfunction” that may persist until the faulty LED module is replaced. 

Sometimes, you may not even receive these crucial alerts, and an integral component of your vehicle may stop working altogether. The best method is to perform a visual inspection of the headlamp unit to diagnose the faulty part.

Reasons Behind Daytime Running Light Malfunction 

Your daytime running lights (DRL) are often malfunctioning due to a failing LED module: 

Lifespan Degradation: LED Modules consist of sensitive components that may degrade over time due to heat, vibrations, and constant use. With time, the LED module may lose its functionality and ability to respond to certain commands, such as turning on your daytime running lights. 

Other potential reasons behind daytime running light malfunction are: 

  • Moisture ingress due to a broken car seal or car washes. 
  • External damages due to car accidents or direct head-on collisions. 

How To Fix The Issue 

In order to fix the daytime running lights, all you need to do is replace the faulty LED module with a similar part number that matches yours. There might be a chance your Porsche Cayenne 92 A may not show any messages, but the faulty DRL may not work at all. 

To resolve the issue, we offer the Hella 170033-10AA LED Module, a factory-fitted LED headlight module designed explicitly for Porsche Cayenne and Panamera cars. With a 1-year warranty and suitable for both front headlights, left or right. After replacement, diagnostic coding is required to alert the vehicle that the malfunction has been resolved.
