Set DRLs to totaly OFF when Low Beams is ON

[zzeelljjkkoo]

Hi,

 

I want to set DRLs to totaly OFF when Low Beams is ON.

How can i do this with OBD11 or VCDS?

 

Thanks

Are they not your Side / Position lights (less bright) when your headlight, low or full beam are on?

In the Fabia mk4, the DRLs are like a strip at the bottom of the headlights, and they always light up at the same intensity, regardless of whether the low beam is on or not.

Hopefully someone can help.

 

Very odd if the same intensity as far as EU Type approval & regulations.

 

Are they not very bright when on as DRL,s then?

 

What is the issue with having them on if you have the head lights on, do you not want to see and be seen?

[Stonekeeper]

Serbia is not an EU member and i believe headlights have to be on during the day?

[Ootohere]

The UK is not a EU member either.

 

But was back in Feb 2011 when the DRL regs came in and New Type Approved vehicles required DRL,s as standard.

Not that we had to have them enabled.  The regs were they were dimmer when the Head Lights were on.

Mk2 Fabia vRS even use the same unit, DRL,s then they dim and are the Sidelights with Headlights on. 

 

If the headlights have to be on in the Day in Serbia that is good, common sense and tail / position lights as well. 

 

I liked my Volvos and Dim dip headlights and tail lights, pre DRL times.

[Stonekeeper]

DRLs are not mandatory in Australia or Japan either but don't see the relevance of other Countries to the OP's question.

 

To answer it we would need to know Serbia's regulations as to why his DRLS stay the same brightness.

 

And to answer how or if he can turn them off?

The OP says of when the low beam is on.  That would be OFF Day time / daylight time if Headlights have to be on all the time. 

So no DRL,s.

 

Someone might be along that knows how to disable the DRL,s that are on all the time on mk4 Fabia if they have ever tried doing that.

If they have ones that are the same intensity day time and night time. 

 

I am interested in what the issue is with having them on with Headlights being on anyway.

 

The issue with Mk2 Fabia vRS daytime and night time is they are in the position that people expect the Fog Lights to be and even Police Officers stopped drivers for driving with Front Fog Lights on.  Other Drivers flashed you.

MOT Examiners even failed cars as recently as last month with a member on here for the sidelights not being operational.

In Serbia it is also mandatory to use lights during the day.
Low beam headlights are used on vehicles that do not have factory DRL lights.
The idea is simple, that the DRL lights don't work when they don't have to because low or high beams are enough for dusk and night.

If you message me with the VIN, I may be able to look up at least which module is in control of them. 

[Breezy_Pete]

The wiring info for your car suggests that there are separate lights for 'sidelight' and daytime running light (DRL) functions, fed by two different wires from the Body Control Module (BCM).

 

On the left side of the car the sidelight wire goes into pin 10 of the 14-way connector at the light unit, and is grey/black

On the left side of the car the DRL wire goes into pin 4 of the 14-way connector, and is blue/yellow

On the right side of the car the sidelight wire goes into pin 10 of the 14-way connector, and is black/green

On the right side of the car the DRL wire goes into pin 4 of the 14-way connector, and is blue/green

 

See which ones of these wires have 12V on in various conditions?

If you can do anything to change the DRL behaviour, it will be via the BCM coding/adaptations. 

 

[zzeelljjkkoo]

Thank you!
My idea and question is whether it can be done by coding/adaptations with OBD11 or VCDS, and if so how?

[Breezy_Pete]

Use VCDS to look around module 09 (Central Electronics/BCM) to see what adaptations are available relating to the DRLs.

 

[Breezy_Pete]

Don't change anything without having a record of how it was originally.
