LED Lights

M.Car

Hey, new to the forum. My LED daytime running headlights have suddenly stopped working on my 2011 XC60. Any ideas? Much appreciated :)

I remember someone else who had a similar problem with an S60, they posted asking about fuses as a DRL plus orange eyebrow had failed on one side.

They ended up pulling out the headlight assemblies to swap them, both worked, swapped back, both worked again. Was a dodgy connector or something I guess.

From the sounds of it both of yours stopped?

M.Car

Yeah both have stopped. Im not sure if its the fuse.

Had Dad check out the fuses before (headlight assembly was busted) and everything looked good. So you reckon its a fuse?

Checking the fuses is always the best starting point with electrical issues.

Your manual should list out the fuses in section 8. The closest I could find in the engine bay was #28 labled "Auxiliary Lights" located as shown:

Im really not confident that it's the right one, though, as the star indicates that it's an optional extra and DRL are standard I believe. It's more likely to be for driving lights, in which case the DRL could run off one of the combination relay/fuses which have a warning not to be touched by the untrained. Being Volvo there would probably be an error thrown up if one was broken.

There is a fuse with "front courtesy lighting", #3 in the glove box B, but that would be a strange place to find it. Also apparently supplies the controls for the powered seat adjustment so that would be an easy way to test. I'm betting it's the interior lighting rather than DRL, though there are two other "courtesy lighting" which might do that. Or might be the puddle lights. Or they might just be different parts of the same system (#6 courtesy/rain sensing is probably the ambient light sensor in the rear vision mirror cluster which feeds into the lighting system). Who knows.

Remember a blown fuse is a symptom of the underlying issue, not the cause, in the vast majority of cases. Plus newer style ones are pretty robust.

If you set your lights to park (when the DRL should light up), do the rear lamps come on? @Philia_Bear could VIDA be set to disable the DRL?

Thanks heaps for the help!

Iirc i thought there might have been a menu option to dosable then in car settings on the infotainment system

You can for sure code them out but that could only be done by a dealer (via software download)

M.Car

Yeah thats what I was thinking! I have looked in the infotainment and nothing. Only settings as to how long you want the LEDs to stay on when you lock/unlock the car.

@Agouti mentioned to check the fuses. I checked fuse position #28 in the engine compartment and there was no fuse in that position. I tried putting a "5" fuse in and then a "10". Still nothing! I have checked the manual and it does not say which fuse controls the LED daytime running lights. BTW my headlights are fixed now! Anymore ideas?
