Volvo XC40 DRL Not Working? Fix It with This LED Board (2020-2022)

TL;DR

On 2020-2022 Volvo XC40, the daytime running lights (DRLs) commonly fail due to a faulty LED board inside the headlight assembly, causing dim, flickering, or dead DRLs. Replacing the DRL LED board (part number varies by trim) restores full function without replacing the entire headlight. It's a plug-and-play fix that takes about 1-2 hours with basic tools.

What Goes Wrong with XC40 DRLs?

The XC40's DRL system uses a light guide (a clear plastic strip that distributes light) illuminated by an LED board (a circuit board with LEDs). Over time, heat cycling from the LEDs and engine bay can crack solder joints or degrade the board, leading to dim or non-functioning DRLs. UV exposure can also yellow the light guide, reducing brightness. Moisture ingress through compromised seals may corrode the board. These failures are common on 2020-2022 models, often appearing after a few years of use.

Diagnosing the Issue

First, check if both DRLs are affected or just one. If one side works, the issue is likely the LED board or light guide on the faulty side. Turn on the DRLs and observe: a dim or flickering light points to a failing LED board. If the light guide looks yellowed or cloudy, it may need cleaning or replacement. Remove the headlight assembly (refer to your owner's manual) and inspect the LED board for visible damage like burn marks or corrosion. A multimeter can test for power at the connector; if power is present but the light doesn't work, the board is faulty.

Step-by-Step Replacement

1. Disconnect the negative battery terminal. 2. Remove the headlight assembly: typically, you'll need to remove the front bumper or access through the wheel well; consult a service manual for your exact trim. 3. Once the assembly is out, locate the DRL LED board, usually attached to the back of the light guide. 4. Disconnect the wiring harness. 5. Remove the screws holding the board and gently pry it out. 6. Install the new LED board, reconnect the harness, and reassemble in reverse order. Test before fully reassembling. Approximate time: 1-2 hours per side.

Fitment Tips

Ensure the replacement LED board matches your XC40's model year and trim (2020-2022). Some trims may have different connectors or board shapes. The Volvo Xc40 needs nothing beyond the swap in most cases; the exception is cars that monitor their lamps and log a fault until the check is disabled. Handle the board by the edges to avoid damaging components. Apply dielectric grease to the connector to prevent future corrosion. Check the light guide for yellowing; if severe, consider replacing it as well for optimal brightness.

Fix vs Replace

Replacing the entire headlight assembly is a common alternative but costs significantly more—often several hundred to over a thousand dollars per side from a dealer. In contrast, replacing just the LED board costs a fraction of the cost of a new headlight assembly and takes about the same install time. By fixing the board, you keep your original headlight housing, which is already perfectly matched to your vehicle's paint and fitment.

FAQ

Standards reference: for the Volvo Xc40, 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. Fitting the new board or guide brings the lamp back to its regulated function.

Most Volvo Xc40 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 the installation take? A: Approximately 1-2 hours per side, depending on your tools and experience. Q: What if only one DRL is out? A: You can replace just the faulty side, but consider replacing both for consistent brightness. Q: Is there a warranty? A: Yes, our LED board comes with a 1-year warranty.
