VCDS (VAG-COM) codes and programmable options for Golf Mk7

[DV52]

^^^ hmm....... OK - maybe try @andyvee suggestion on the link below (Octavia has the same DNA as a Golf mk7/7.5 - MQB platform)

Enabling boot closing from keyfob and interior button using VCDS - Skoda Octavia Mk III (2013 - 2020) - BRISKODA

Hi, help me

I changed the front halogen MK7 2014 lamps to halogen polift 2018 with LED daytime running lights 5G1941005D and 5G1941006D. Both lamps have a 10PIN plug. Additional cable for TFT to BCM added


I can't turn on the daytime running lights and position lights
can you tell me what adjustments i need to change

@memus:Hi.

Hmm...........I have absolutely no doubt that you know much about "polift 2014" headlights and also that you are well versed with the particular "TFT to BCM" cable that you mention (why was this cable needed if both the new fittings and the existing car-loom connectors have 10 x pins?)

However, I'm not sure that many of us on this forum share your expertise. If you want assistance, maybe it would help if you share this information. So, please provide more words and specific information about the new equipment

old lamp 5G1941005


new lamp 5G1941005D

old and new halogen lamp, the new one has only LED daytime running light and position LED.
both lamps have a 10PIN plug
added cable from pin 10 of the lamp to BCM pin 10 for the left lamp and pin 10 of the lamp to BMC pin 21 for the right lamp
I want to code a new lamp to work properly

5G1941005 is the standard lights off Golf 7.
5G1941005D are for Golf 7.5.
I didn't think Golf 7.5 lights were compatible with the earlier Golf 7.

@memus: Thanks for the information. I'm a little bit better informed now.

When you say "BCM pin 10" and "BCM pin 21" - I suspect that you know that there are actually 3 x separate "pin 10" and "pin 21" on a BCM because the hex09 module has 3 x sockets - like this:



I assume that you are you referring to Socket B - is this correct?

If my assumption is correct - then you could try this for side marker lamps:

Leuchte2SL VLB10 and Leuchte3SL VRB21

• Lasttyp > 43 - allgemeine LED [8 - allgemeine Glühlampe 12W]
• Lichtfunktion A > Standlicht allgemein (Schlusslicht; Positionslicht; Begrenzungslicht)
• Dimmwert AB > 127 [100]

Note: it's not clear from your picture if the side-marker lamps in the new headlight fittings are LED, or incandescent. My coding above assumes LED lamps. If the new fittings have incandescent side-marker lamps, use the square-bracketed values.

The DRLs are a tad more tricky because on genuine OEM headlights, VW ONLY produced LED type DRLs on fittings that had 14 x pin connector on a Golf mk7. Your headlight assemblies have ONLY 10 x pins - so clearly your fittings are NON OEM for this car! This means that it's anyone's guess how the DRLs on the new fittings are designed to operate.

On a genuine OEM mk7 headlight with LED type DRL, there are 2 x separate wires that operate the DRL; there is a power-supply wire and there is a separate signal wire that controls when the DRL illuminates and its dimming level.

The DRL signal wire on a genuine mk7 OEM headlight is connected to your "BCM pin 10" and "BCM pin 21" on socket B. - but I'm assuming from your words that these pins are used for side-marker lights on the new fittings.

So. my guess (emphasis on "guess") for the DRLs is:

Leuchte4TFL LB4 and Leuchte5 TFL RB32

• Lasttyp > 4 - LED Tagfahrlichtmodul Signal
• Dimmwert AB > 100

@flipper Dog: You are 101% correct - this is a very NON OEM retrofit!!

Not sure if it's totally "incompatible". Worth a shot (I think) - let's see if we can fool the BCM into thinking that mk7 headlights are fitted!!

Yes exactly,
Left lamp PIN 10 ---> BCM PIN 10 plug B 46PIN
Right lamp PIN 10 ---> BCM PIN 21 plug B 46PIN

Yes I have it connected




In the place marked in yellow there are LED daytime running lights




This is a genuine OEM VW lamp with 10PIN socket and LED daytime running light and LED position light


On the sticker of the lamp it says DRL/PL 4LED


Thank you for the info what should I change in the adaptations, I'll check if it works and give feedback

hmmm.......... yes, I have no doubt that your new headlights are "OEM VW lamp" - but these particular fittings were NEVER made to be installed on a Golf mk7.

My point is that these new headlights are "NON OEM for this car!"

The Golf mk7 was built with a 10 x pin halogen headlight fitting that had a side-marker lamp connected to pin #10 (the wire from which terminated on pin #B10 and pin #B21 on the BCM). However, this version headlight fitting had incandescent DRL lamps (not LED type DRLs as in your new fittings)
