Renault Kadjar DRL Not Working? Fix It with a New Module (2013-2019)

TL;DR

On 2013-2019 Renault Kadjar models, the daytime running lights often fail due to a faulty DRL module or heat damage to the LED board. Replacing the module with a plug-and-play unit restores proper DRL function.

What Goes Wrong with Kadjar DRLs

The DRL module in the Kadjar is a small electronic unit that powers the LED daytime running lights. Over time, heat cycling from the engine bay and constant use can cause solder joints to crack or the LED board to degrade. UV exposure can also yellow the light guide, reducing brightness. Eventually, one or both DRLs may stop working or become noticeably dimmer. This is a common issue on 2013-2019 Kadjars, especially in warmer climates.

How to Diagnose the Problem

First, check if both DRLs are out or just one. If only one side fails, swap the left and right modules to see if the problem follows the module. If it does, the module is faulty. If the DRL still doesn't work, the issue may be wiring or the LED board itself. A simple multimeter can check for power at the module connector. Also inspect the light guide for cracks or yellowing. If the module is receiving power but not outputting, it needs replacement.

Step-by-Step Replacement

Replacing the DRL module is a straightforward DIY job that takes about 1-2 hours. Start by disconnecting the battery. Locate the DRL module behind the front bumper, usually accessible through the wheel arch liner. Remove the liner screws to gain access. Unplug the electrical connector and unscrew the module from its mount. Install the new module in reverse order, ensuring all connections are secure. Fit and go on most Renault Kadjar cars. Where a warning does appear it is the lamp self-check, cleared by coding rather than by swapping parts. Test the lights before reassembling everything.

Fitment Tips

Ensure the module is designed for the 2013-2019 Kadjar. Check that the connector matches your vehicle's harness. Before installation, inspect the new module for any damage. Apply dielectric grease to the connector to prevent moisture ingress. Avoid over-tightening screws to prevent cracking the housing. After installation, check that both DRLs illuminate evenly. If one side remains dim, the light guide may need cleaning or replacement.

Fix vs Replace

If your Kadjar's DRL module fails, you have two options: replace just the module or replace the entire headlight assembly. A new headlight assembly from a dealer can cost several hundred dollars or more, while a replacement module is a fraction of the cost of a new headlight assembly. Replacing the module takes about 1-2 hours and keeps your original housing, preserving the factory fit and appearance. For current pricing on the module, check the product page.

FAQ

Standards reference: for the Renault Kadjar, the daytime running lamp is governed by UN ECE Regulation 148 (which superseded R87) in most markets and by FMVSS 108 in the United States - these define when the lamp runs and at what output. Replacing the failed board or guide restores the function those rules describe.

Q: Will this module fix both DRLs? A: It replaces one module; if both are faulty, you may need two.

Most Renault Kadjar cars are plug-in and done. A few log a fault until the lamp check is coded off; ask us if your car is particular about lamp diagnostics.

Q: How long does installation take? A: Typically 1-2 hours for a DIYer.

Q: Is there a warranty? A: Yes, our module comes with a 1-year warranty.
