DRL/Licence plate lights not working


Yepecece

Recommended Posts

I have a 2007 Skoda Fabia. My DRL where working fine yesterday morning! When I used the car back in the afternoon they were not working anymore! What could be the problem?

In my Fabia there is no DRL switch next to the fuse box (Only a hole). The Licence plate lights do not work neither although when I turn the lights on they work.

I looked in the manual to check what fuse controls the DRL but there is nothing stated.

Thanks for your help.

To my knowledge that's exactly how they are supposed to work, I've never seen any other setup and I see no reason why that would even happen, it served no purpose.

Did you try the fuse?

I checked fuse 17 and it works. If I take it out license plate does not work anymore (with lights on). One think I just realized is the the front left side lamp is not working. Could this be the reason DRL does not work?

 

I will try to replace it tomorrow to see if it fixes the problem.

 

Thanks

It shouldn't really make any difference as they are on a different circuit. Has the car been into the garage recently? They have a habit of turning them off over here while they work on the car so maybe they deactivated yours and forgot to turn them on again.

It could be a massive coincidence that both bulbs have gone at the same time but I doubt it. My number plate bulbs weren't anything to do with my DRL'S they stayed on without the fuse in, I would try changing the fuse completely with a new one.

I changed the fuse and still the same! I have a TDI sport edition!

The car was not in the garage! I just parked it on Monday morning, all working fine and when I drove it at midday it wasn't working anymore.

I'm trying to change the sidelight but it's a pain. I will keep trying.

Here is the sidelight bulb. I still cannot change it as it is very tight.

The sidelight/parking light is B (W5W bulb)

The reason I know my license lights used to work without turning the lights is because I tapped my rear camera to them and it worked perfectly.

Now I have to turn the lights on in order to see the camera. This is why I think it could be a fuse problem.

 

If DRL is not factory on this model how could it be achieved? Could it be located in the fuses at the battery?

Also, as in this post (http://www.briskoda.net/forums/topic/378121-license-plate-ligths-of/?hl=%2Blicence+%2Bplate+%2Blights#entry4437215), my license plate were on with DRL.

 

Thanks

So to clarify, your car is set to Scandinavian and it is a 2007 model. Pre or post May?

The side light just needs a good firm pull away from the hole it is situated in, a pair of pliers around the plastic will do the job. I've never had a problem.

Do you have a picture of the front of your car? Does it look like this...

I will have a look at fuses under the bonnet but I have to say it's unlikely to be an issue as they carry more load and protect the bigger systems of the vehicle.

I don't understand why the plate lights don't illuminate unless the lights are on, if there is a problem they will illuminate or they won't.

My best guess now is that somehow your vehicle computer has changed the country to something that does not require DRL. I'm stumped. Do you have access to VCDS?

My fabia is from december 2007. I am in switzerland and I think it was imported from germany.

I don't have access to VCDS. I will post a pic of the front tomorrow.

 

Also, could it be that I deactivated DRL unintentionally (http://www.briskoda.net/forums/topic/233661-drl-led-lights-modification-to-mk2-pre-face-lift/?p=2744466).

I don't think this technique applies for older models. I tried but don't seem to work.

 

Thanks

Just my thoughts...

Are you 100% sure it is the number plate lights your wired into? It sounds as if number plate light is working as it should.

Do you have DRLs or are they fog lights? Does the rear fog light work as it should? It is controlled by the lighting switch and is it possible that the fog light fuse is blown or fog light switch in off position.

Are they used as driving lights?

Just a possibility, thought I would ask!

I'm 100% sure since it's the cable that goes straight to the light. I'm not sure which lights used to be on as DRL but I believe it was the low beams. All lights work when I turn them on.

Before, as soon as I would turn the key the lights/DRL, plate lights and therefore rear camera would turn on.

Now they only work if I turn the light switch on.

Really weird!

And for info here is a pic. It's got the round fog lights.

The main beam (circular hazy lookin bit) is a H7 55w bulb. It does both low and high beam using a solonoid and a shutter system, but is constantly 55w. Theres no other bulbs in there.

The outter bits are the sidelights. Theyll come on thwn the switch is in the middle, along with the rear lights and the numberplate lights.

The bottoms ones on the bumper are just fogs

I'm struggling with this one, as far as I can see and know your car does not have DRL'S

What you have described is you have been running around with your side lights on.

From what I can make out from your responses they where coming on with the ignition even if the switch was in the 'off' position. There is no way, in my mind the bulbs would dim when the switch was turned to 'sidelights'.

Have you owned the car from new? Have you had any error messages on the dash? Have you recently disconnected the battery.

My best and last guess is.... You're sidelights have had a short in the circuit the whole time or the bulb that has blown has somehow been connected to a switched live.

I bought the car from a particular! I never paid to much attention to the lights that were on with the light switch was on off but I remember the light would be less intense when the switch was in the middle position which is why I believe that it could be the low beam that was always on.

Also, I tapped my rear camera to the plate light because they were always on and because the power cable would no have to go al the way up the trunk!

Everything was working fine for at least 6 months.

I Checked all the fuses and they all are working fine!

The left sidelight that was not working and has been behaving strangly because now it works. I'm not sure if the connection was loose and by moving it fixed.

I have never disconnected the battery nor had an error light.

I guess it is not a big deal since by law my lights have to be on, so it's just a matter of turning the light switch every time but it is rather strange.

I have been looking and this is what my setup was.

It was the low beam at reduced intensity.

 

https://en.wikipedia.org/wiki/Daytime_running_lamp

Implementations[edit]
220px-Lowbeam_DRL.jpg
 
Full-voltage vs. reduced-voltage (DRL) operation of low beam headlampon European-market Volkswagen

Depending on prevailing regulations and vehicle equipment, the daytime running light function may be implemented by functionally specific lamps, by operating the low beam headlamps or fog lamps at full or reduced intensity, by operating the high-beam headlamps at reduced intensity, or by steady-burning operation of the front turn signals. Compared to any mode of headlamp operation to create the daytime running light, functionally dedicated DRLs maximize the potential benefits in safety performance and minimize fuel consumption, glare, motorcycle masking, and other potential drawbacks.[2]

To prevent drivers from using DRL when low beam headlights are needed, some regions require the dashboard lights to be turned off when DRL are turned on.[citation needed]

Right, I think I have finally got my head round this, thank you for your patience Yepecece.

I understand the reduced voltage principle and how it works for DRL'S it is used on the side lights/DRL'S on the vrs so obviously something Skoda use. I just wasn't aware they used it on other light units.

I am also doubtful that it was implemented on the low beams in the projector lens using the H7 bulb. My best guess is that you are right, in your country DRL'S work with tail and plate lights. I think however it is likely that it is the side lights that are used in this way, especially that you have a temperamental side light leads me to think this, that being the case it may be a relay at fault rather than a fuse, the part that reduces the voltage is not working. Unfortunately I have no idea what part that is, I would say an auto electrician would be the cheapest diagnostic point.

This has had my brain riddled so if you find the answer please let me know.

I believe this has been installed and that may be the relary or maybe the fuse that comes with it that is not working.

I need to find it but does anyone know how to access without too much trouble the relays? There is a plastoform plate that covers the full leg room below the fusebox.

Thanks
