I've always found the 3rd brake light to be a much undervalued facility on a car. Truth is that on a mk7, it can be used to do all sorts of additional functions (other than just being a brake light). On my highline, the third brake light was factory fitted with an LED.

Here's some options for how the role of the 3rd brake light can be expanded. I discovered these instructions as part of material that I received from a forum colleague (Many thanks - Morde), who resides in Germany and therefore has access to a richer information base than us English folk (and he understand the German language- which is a great attribute to have when trying to decipher VW's cryptic nomenclature)!

Note: for the three tweaks shown below, the structure of the changes across the Leuchte-set channels (and the non-Leuchte set channels) are arranged so that each individual tweak is independent of the other options. Pick-and-choose whichever tweak that you like (or choose none!),

I implemented all three options on my car this morning and I can vouch that they all work

Cheers

VW Golf MK7 taillight non LED conversion - NAR to ROW - amber turn light

Hi folks
This is my first “post” so hopefully it goes in the right thread..
I have a 2015 E-Golf North American version (NAR) and want to replace the tail light with OEM EURO tail light – NOT LED to get amber turn signal. There are lots of writing on the net about LED conversion but I could not find exactly my problem.
I used this link as guide:
VWVortex.com - LED Taillight Wiring & Coding Thread (North American Golf/GTI)

I have purchased EURO tail light - (outer left and outer right ROW version) and installed them onto the car - no changes to: inner left and inner right tail light.
I only changed the cable pin configuration for the outer tail lights and programmed “leuchte” A71, C8 and C6

My main problem after the conversion: when I hit the brake, both amber blinkers(A71&C act as a brake light.

Here is what I did on left side:
Stock outer tail light (NAR) cable has 3 cables/pins:
1. Red (A71) in PIN 1 (combined brake/turn signal/ park…)
2.GND in PIN 2
3. C6 in PIN 4 – Red side marker LED

I repinned the left & right cables to a new configuration to match the EURO outer tail light – non LED and changed values in VCDS
New configuration:
1. Red (A71) into PIN3 (amber turn signal) – programmed A71 as turn signal in VCDS
2. GND stays in PIN 2
3. C6 into PIN 1 to become brake and driving tail light. – (programmed C6 as brake light and park/running light)

Idid the same changes for the right side (C

So what is happening on the outer tails.
1. Amber section of the Euro tail light works nice as a blinker(A71&C – as it should
But when I hit the brake, both amber blinkers(A71&C lights up together with the red brake light in C6, so there is 2 “brake” lights in the outer tail light – one red and one amber.

2. The red section (C6) have some issues also. Light comes on but blink and dies out when turning on the light switch on the dash. If I touch the brake – the red light (C6)will stay on – as they should and they work fine.
(the reason can be two pcs W21W bulbs on the same line(C6) probably solved if I use LED 7440 instead.


So to sum up:Light (A71 and C6) both show the brake light - but A71 is only programmed as turn signal - se coding underneath.
The strange ting is this. The E-Golf has a ECO B-mode (regenerative braking) on the gear shifter.
If the car is in B-Mode it will turn on the brake signal automatically if you lift the foot of the accelerator and when it does – the brake signals works perfect – no light in the amber section (A71) - just brake signal in C6 lamp - so the B-mode understand my programming and repinning of the cable/wires


So everything is working perfect except when I hit the brake pedal.

Is there a problem using Leuchte A71 as a turn signal only? Is A71 & C8 tied to the brake system? - I see other people has shown programming examples A71 & C8 as turn signal, but I do not know if they have had success.



Any idea what I can do to solve the problem?
My hope is to avoid wiring from dashboard/BCM to the tail or open up the hatch and take turnsignal from (C10)



Appreciate if somebody can help.

HFL: Helo og velkommen til forumet!

I've had a quick look through your Leuchte-sets and I don't believe that the continued operation of the brake function on the turn signal lamps is due to any of the settings for the Leuchte channels.

Rather, I suspect that the solution lies in the code-string for the BCM (not in the adaptation channels in the BCM). However, I fear that VCDS will be of little help in solving this problem! Don't get me wrong, I think that VCDS is a most excellent tool, but (for some reason) there are many Byte/Bits in the long coding helper screens missing their function descriptions.

Nevertheless, I can suggest a way forward - if you can get access to an OBDeleven dongle. Not sure if you are familiar with this device, but I wrote a explanation HERE which may be of interest.

OBD11 handles "long coding" a little different to VCDS, but it appears to be more informative when identifying the function of Byte/Bts for control modules. Unfortunately though, the screens that OBD11 uses for the "long coding" descriptors, don't identify the Byte/Bit numbers (i.e. there are no "tick boxes" next to the Bits as per the long coding helper screens in VCDS).

So - I suspect that the way to solve your problem is to disable the Btye/Bit that I have surrounded in the yellow box in the screen shot below, which is from the "long coding" part of OBD11. I suspect on your mk7, the entry for this Byte/Bit is Yes (on my RoW car, the entry is "No"). Alas, as you can see there is no Byte/Bit number on the picture to translate to the long-coding screens on VCDS!

You might even consider buying an OBD11 device - they aren't that expensive!

Don



EDIT: Whilst I still think that the process outlined above is the proper way of fixing your problem - if you aren't able to access an OBD11 dongle, perhaps it might be possible to "neutralize" the boxed Byte/Bit setting in the screen-shot above?

This is an entirely untested suggestion, but if you include the Leuchte command for the Brake-light into the 2 x Leuchte-sets for the blinkers and you attach a dimming level of zero to this command - perhaps this will counter the effect of the coding Byte/Bit. Not sure, but it's a simple change - so worth a try (I think)

So - my alternative suggestion is to try this:

Left-side Turn-signal	Existing	New
(8 )-Leuchte20BR LA71-Lichtfunktion C 20	not active	Bremslicht
(9)-Leuchte20BR LA71-Lichtfunktion D 20	not active
(10)-Leuchte20BR LA71-Dimmwert CD 20	0
(11)-Leuchte20BR LA71-Dimming Direction CD 20	maximize
Right-side Turn-signal	Existing	New
(8 )-Leuchte21BR RC8-Lichtfunktion C 21	not active	Bremslicht
(9)-Leuchte21BR RC8-Lichtfunktion D 21	not active
(10)-Leuchte21BR RC8-Dimmwert CD 21	0
(11)-Leuchte21BR RC8-Dimming Direction CD 21	maximize

Don do you have any ide about what the sideblinkers i the mirrors has for Leuchte number

[HFL]

Hi Don and thank you for your kind Norwegian welcome to me I was very happy when I saw it was you who answered my request to the forum because I have seen so many good and well documented answers and advices from you.

I agree about your assessment regarding decoding code string in VCDS and I will order the OBD11 asap and follow your suggestion.
I also tried your alternative suggestion today: dimming level "0" for brake light in the leuchte set for blinkers and that almost solved my case, but still there is a little short flash in the blinker (0,3 sec) so I will go for your OBD11 advice and report result back to you.
Thank's again.

Don do you have any ide about what the sideblinkers i the mirrors has for Leuchte number

jisses: Hej och välkommen till forumet

Some VW models do have a Leuchte-set for the two blinker repeater LEDs on the side mirrors ( i.e. the new Polo 6C). However, the mk7 does not - alas.

If you look at the wiring diagram for the mk7, you will find that the repeater LEDs are connected directly to the door control modules - there is no physical connection from the LEDs back to the BCM.

Since Leuchte channels ALWAYS reference a pin number on the BCM, it's not possible to have such channels for the repeater LEDs (because they are not connected to the BCM). What I think happens is that the turn signal information (which originates in the steering column control module) is sent to the door control modules and therefore to the repeater LEDs via the convenience CAN bus.

[jisses]

So i can find it in the door control module if i have any luck

[DV52]

jisses:my apology - I'm not making my point clear enough. No, there are no Leuchte channels in the door control modules (leuchte channels only appear in the BCM). So, no you can't modify these LEDs. Why do you want to modify these LEDs?

I want them to glo like US frontblinker

?? -...... I don't understand!! Currently the mirror LEDs flash the same (in unison) with the front/rear blinkers. What do you want them to do?

Parking lights in the US include the front indicator globe.

Mysticality: Thanks for the response - I kind-of knew this, but as I understand, the mirror repeater LEDs don't light-up as parkers in US mk7s. I could be wrong, but I believe that the sole function of mirror repeater LEDs on NAR models is to behave as turn-signals.

But if OP wants the mirror LEDs to function as parking lights as well as turn-signal, then this is a unique combination (in the world - I think) and I'm fairly certain that it's not possible - more than happy for someone to tell me otherwise and to explain how it's done!

[Mysticality]

This is also my belief - however I know the Jeep Wrangler's side indicators do light up as parking lights.
Whether any other USDM vehicle does; I have no idea.

Hello to all the forum, wonder if here in your community there is a detailed guide (video tutorial) maybe postandomi the link on how to install lights and wipers on Golf MK7 where I can figure out where to put the famous wire 9 from the handle to the control unit BCM / C.


In my Golf it is already the rain / light / humidity sensor - 8U0 955 559 B.


I apologize if I'm wrong "section" but also from Italy using google translator I could not have found anything.


Here I found this link in Italian:
