BMW F30 Daytime Running Lights Not Working – Need Help!

Problem Overview

I’ve been having issues with my BMW F30’s daytime running lights (DRLs) not functioning, and I could use some advice or troubleshooting tips from anyone who’s dealt with this issue before.

What I’ve Noticed

  • No Indicator on Dashboard: There are no warnings or indicators lit up on the dashboard when I start the car.
  • Lights Don’t Turn On: I’ve checked the light settings, and they’re set to the auto option, but the DRLs still don’t activate when I start driving.

Steps I’ve Taken So Far

  1. Checked the Fuses: I checked the fuses related to the lighting system and didn’t find any blown fuses.
  2. Replaced Bulbs: Although the DRLs are usually LED, I replaced the bulbs just in case there was a fault (although unlikely).
  3. Software Update: I took it to the dealer for a software update, as I was advised that sometimes the DRL function can be affected by software issues.

Questions for the Community

  • Has anyone experienced this issue?
  • What other troubleshooting steps should I consider?
  • Are there known common electrical issues in F30 models that could be causing this malfunction?

Any advice or shared experiences would be really appreciated. Thanks in advance for your help!

Possible Causes to Consider

  • Faulty Light Control Module: Some users have reported that their light control module went faulty, affecting the DRLs.
  • Wiring Issues: Check whether there’s any exposed wiring or corrosion that could be affecting the connection.
  • Settings Configuration: Sometimes specific settings might need adjustment using the onboard computer or via coding.

Summary

I’m hoping some of you can provide insight or share your experiences. Your help could really turn around this annoyance. Looking forward to your responses!

I’ve had issues with my F30 DRLs too! Usually, it’s either a blown bulb or a blown fuse. Check your fuses first, they’re easy to check and replace if needed.

I agree! Sometimes it’s just a loose electrical connection. It can be a pain to find, but worth it once you do!

Have you checked the DRL fuse? It’s often overlooked but can be a common culprit! The location is in the fuse box under the hood.

I’ve had a blown bulb before and thought it was a bigger issue. Swapped it out, and everything was fine! Might be worth checking that first.

Good point! Also, make sure to check the connections at the bulb socket. Sometimes they get corroded.

As a fellow F30 owner, I can confirm these issues! A friend had a tough time with the connections – had to clean them up to make the lights work again.

Let’s not forget about the possibility of a bad relay as well. It can totally stop the DRL system from working.

Exactly! If you’re handy, you might want to test those relays yourself. They’re often overlooked.

I had no idea DRL issues could come from so many places! Thanks for the tips everyone! I’ll go check those fuses and bulbs.

One other thought - if you’ve installed aftermarket parts, they might interfere with the stock DRLs. Be cautious with that!

It’s kind of funny how something so small like a bulb can cause such a headache! It feels like a major repair when it’s really a $5 fix.

13

Right? And then you feel silly for not checking the simplest things first. Live and learn!

14

If all else fails, consider taking it to a shop. Sometimes you need a professional to cut through the confusion!

I was just about to say that the dealer automates everything these days. Sometimes they can pinpoint the issue quickly if it’s electrical.

16

I love how supportive everyone is! It’s like we’re a little F30 family helping each other out!

17

Absolutely! It’s crucial in this community to share our experiences; it makes everything a bit easier!

18

At the end of the day, it’s just lights. Just make sure you stay visible on the road! Safety first!

I’ve had the same issue with my F30! First, make sure the DRL fuse isn’t blown. You can find the fuse box under the hood. Just check the diagram on the cover for the right fuse.

A quick step: Inspect the bulb itself. Sometimes it just needs a simple replacement! This can be a DIY if you’re comfortable.
