Daytime Parking Lamp Malfunction on My BMW - Need Help!

BMW
1

Overview

I’ve been having issues with my daytime parking lamps on my BMW and I’m hoping someone here can help me figure this out. They seem to flicker occasionally and sometimes don’t turn on at all.

What I’ve Noticed

  • Intermittent Flickering: The lamps are flickering when I first turn the car on.
  • Complete Failure: Sometimes they don’t light up at all, which is worrisome since I use them during the day.
  • No Error Codes: I checked the dash, and there aren’t any warning lights regarding the headlights or parking lamps.

Things I’ve Tried

  • Checked the Bulbs: I replaced the bulbs thinking it might be a simple fix, but that didn’t solve the problem.
  • Fuses: I checked the fuse related to the daytime lights, and it seems to be okay.
  • Connections: I’ve inspected the wiring harness for any visible damage but everything looks fine.

My Questions

  1. Common Problems: Has anyone else experienced this with their BMW? If so, what was the cause?
  2. DIY Repairs: Are there any DIY methods to diagnose this issue further? Any guides or resources anyone can share?
  3. Professional Diagnostics: If it comes down to it, is there a recommended service or mechanic who deals with these specific issues?

Additional Info

I drive a 2017 3 Series, and I’ve seen some threads around prior issues with the daytime running lamps but wanted to get some current insights. Any suggestions or help would be greatly appreciated!

Thanks in advance for your support!

I’ve noticed flickering on mine lately, definitely a sign something’s off. It only happens when I first start the car. Have you experienced anything similar?

Yes! I’ve had that happen too! I also noticed inconsistent brightness at times. What did you do to troubleshoot it?

In my case, complete failure was the biggest red flag. I went from intermittent flickering to none at all! Does anyone know if this is an easy fix?

5

That sounds frustrating! I had inconsistent brightness that would sometimes go out completely, which prompted me to check the fuses.

6

I’ve read that electrical issues might cause flickering. It can be tricky diagnosing it yourself. Maybe start with the bulbs and fuses?

7

Great tip! I’ll check the bulbs next! I guess it’s better than a costly visit to the mechanic.

Mine was just a loose connection. A little wiggling around fixed it! Have you checked all the connections?

I haven’t had a chance to check that yet. I’ll try that before anything else. Thanks for the idea!

Daytime lights failing can sometimes indicate a bigger issue with the electrical system. Keep an eye on other lights too!

11

That’s good advice! I’ve had other lights flicker before, and it cost me a pretty penny. Any DIY fixes?

12

Don’t you just love how car problems always seem to happen on the worst days? I feel your pain! Is it time for a good ol’ car check-up?

13

Seriously! It’s like they have a timetable to break down! I’m hoping it’s just an easy fix like you all mentioned!

14

I had a similar issue with my BMW. First, check the fuse for the daytime running lights; it could be a simple blown fuse causing the malfunction.

15

Great tip! If it’s not the fuse, check the bulb next. Sometimes it just needs a replacement. They’re pretty easy to change if you look up a guide online.

16

Has anyone tried a DIY reset of the lighting control module? I heard it can sometimes fix odd electrical issues. Just disconnect the battery for a few minutes.

17

If you’re not comfortable doing it yourself, I recommend checking out local mechanics who specialize in BMWs. They often have the correct parts and know the finer details.

18

My mechanic charged me $100 to fix my daytime lamp. It was worth it for the peace of mind. Sometimes saving a few bucks DIY isn’t worth the hassle!

I totally agree with that! As long as you’re finding a trustworthy mechanic. Has anyone here used a specific service center they’d recommend?

Yes! I took mine to BMW of Anywhere, and they were fantastic. Just be prepared for the higher pricing. Worth it in my opinion!
