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

[DV52]

@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.

[DV52]

@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)

Don

[memus]

Lights are daytime running thanks to the changes in the adaptation

Thanks Don

When the dipped headlights are on, they do not light up as daytime running lights
Parking lights do not work after removing the key, do not light up in the front lamps. they only light up in the rear lamps

[DV52]

@memus: I think that you are saying that my suggestions worked (at least in part)- but I'm not entirely sure?


In regards to the dipped headlight matter - yes, that's the way that VW coded the Leuchte-sets for the left/right side DRLs. As factory set, the DRLs were coded so that they did NOT illuminate when the low-beam lights turned -ON. This is because the DRLs (on genuine OEM headlight fittings for a mk7 that used incandescent lamps) shared the same physical lamp base as the high-beam lamp (i.e. it's a H15 lamp base with 2 x separate filaments). This means that the incandescent DRL lamp also shared the same reflector as the high-beam lamp - which as you will know, does NOT have cut-off characteristic. So just as illuminating the high-beam lamp would blind on-coming vehicles, it must have been considered by VW that turning-ON the DRLs during night-time would do the same (I guess)

As factory-set and other than the normal daylight function, incandescent DRL lamps were coded on a mk7 to turn-on ONLY when the rotary light switch was in the position (i.e. when dipped-beam was OFF) and in this mode, the DRLs were dimmed to 31%.

So, if you are of the opinion that your LED DRLs won't blind on-coming vehicles - try this (I wote a more fulsome instruction-set HERE):

For Leuchte4TFL LB4 and Leuchte5 TFL RB32

• ONLY IF Lichtfunktion E is set to Standlicht vorn (Positionslicht; Begrenzungslicht), change to Standlicht allgemein (Schlusslicht; Positionslicht; Begrenzungslicht)
• With the above change made, adjust the illumination level to suit night-time operation of the DRL by tweaking the value of Dimmwert EF (factory setting=31). I'm not sure if the LEDs in your new fittings will tolerate dimmed operation - if not, you might need to set the channel to max value = 100. In this case, make sure that the blinding effect for on-coming vehicles doesn't happen - please

Again, don't make these changes if the existing setting for Lichtfunktion E is not as indicated.


OK, next matter !

It's not clear to me what you mean by "Parking lights do not work after removing the key, do not light up in the front lamps. they only light up in the rear lamps".

On a Golf mk7, the Parking-Lights/Position-Lights "do not work after removing the key" as factory coded (unless the turn-signal stalk is left in one of the car-side positions). This is normal behavior!

If your "rear-lamps" do remain switched-ON as Parking Lights after key removal - then I'm guessing that they are coded as Coming/Leaving Home - is this what you are referring to?

If you want the side-lights to operate as CH/LH, do this:

For Leuchte2SL VLB10 and Leuchte3SL VRB21

• Lichtfunktion C >Coming Home oder Leaving Home aktiv
• Dimmwert CD > 127 [100]

Again, I don't know if the side-lights are LED, or incandescent. If the latter, use the square bracketed value

Hi All, I've just started playing with a 2019 Golf Wagon, boy what a learning curve! Slowly getting the hang of it.

I haven't been able to find what this actually changes, as I'd like to change it in VCDS: https://obdeleven.com/supported-vehi...-roller-blind=

I'm also looking to see if it's possible to not have the front fog lights come on, if the rear fog light is on. I find it strange, as for example during the night it's not legal here to have the front fogs on with the headlights, however you can with the rear fogs. But you can't get the rear on without the front!

[DV52]

@yorky: Hi and welcome to the wonderful world of VW coding!! I'm sure that you will have an enjoyable learning experience as you navigate the mysteries of diagnostic devices - like VCDS!

So, as for your specific question - I don't know the answer, but I can make a suggestion that might enable you to find a way forward.

Not sure if you are aware, but the modules in your Golf mk7.5 use 2 x different protocols for messaging to one another. The primary skeleton for communication is called CAN (Controller Area Network) and it's the high-speed facility that connects most of the key modules together.

Separate to this is something called "LIN" (Local interconnect network). As the name implies, LIN is a localized smaller network that lots of modules use when the thing being controlled is really only of interest to a single CAN module. On LIN based system, there is ONE LIN-master module (this module is also a CAN based module) and up-to 16 x LIN-slave modules

The reason for describing this is because the Sunroof Roller Blind module is a LIN-slave to a LIN-master module which VCDS calls the Cent. Elect. module (J519) . In the VW wiring diagrams, the Sunroof Blind module is known as "J394". If you look at the SCAN for this car- you should find the Sunroof Roller Blind module reported like this:

No fault code found

Of course the details on your car will be different -but notice Subsystem 4 and notice also that this module has a "Coding" string - which VCDS calls "Long-Code.

So, my guess is that you will find the answer to your question if you navigate to the Subsystem 4 module -> then select Coding -> then select Long Coding Helper -> then look through the descriptors on the Bits for each Byte

As for your front fog light question - yes this is possible. Do this:

In the Cent. Elect. module @ address 09 - go to Adaptation and make these changes:
for Leuchte12NL LB45 and Leuchte13NL RB5

• Lichtfunktion G > Nebelschlusslicht wenn kein Anhaenger gesteckt (not active)

• Dimming Direction GH 13 > minimize (maximize)

The setting in brackets above are the existing values - ONLY proceed if these are current in your module

Don

[yorky]

Thanks! I've read a lot of your posts, and your dedication to public knowledge is simply fantastic.


I'll have a look for that subsystem shortly, and look at the fog light thing, that's awesome that it's as easy as that!


A couple more questions popped into my head, I've just received some LED front fog lights, and a straight swap hasn't brought up any faults. Does this mean I don't need to change any codes? It's this one (they are extremely bright!) VW Golf Mk7 Remnant LED Fog Light 6000K (Pair)
– Supernova Lighting


And I've tried to enable the alarm via the below link (and I've seen similar settings around as well, no I don't have the factory alarm), however VCDS says in the coding of 09 (BCM PQ37BOSCH xxx xxxx) current coding all zeros and it can't access it. Any ideas if it's still possible to enable the alarm via horn? I've done all the adaptions.
