 I cant find a solution online to solve this outer lamp issue. Left side (drivers) of the tail light is not illuminated while the right side is. With the headlamps off, the right illuminates and the left doesn't. With the headlamps in auto, both illuminate . Right side illuminates when car is unlocked with remote while left doesn't. I've compared both sides in OBDeleven and both sides match in the different channels I was comparing. |

Could it be a rear fog light is on.

medsox : Hmmm........ we don't know whether this is a LHD, or RHD car - so it's unclear if this side tail-light even has a fog light in the fitting!!
My total guess (I'm not even sure that this is a non American car), but on RoW models, this is the closest fitting that I could find (note: fog-light is on RHS tail-light fitting because Australia's cars have the steering wheel on the right-side):
Picture originally posted on my local forum by @ardil
So - my hunch is that unidentified light in OP post is the right-side turn-signal - maybe?
My guess (emphasis on the word "guess") is strengthen by OP statement "Right side illuminates when car is unlocked with remote while left doesn't" - but I'm not sure!!
Anyhow, guessing is NOT a useful process on these forums - nowhere near enough information provided to pursue this matter (IMO, of course).
We need more words (meaning specific details about these tail-lights and what's happened to this car) and maybe a copy of the instructions?

Thanks for the response.  Let me clarify. US 2019 Golf R Tail lights: ShopDap Mk7.5 harness and tail lights Car is LHD. In new picture, the right outer, and bottom section of light is ON only on the right side when: 1. Having the car idle, with the headlights in the off position. 2. Hitting the unlock button on the remote and the right side will illuminate while the left doesn't. DV52, the tail lights in your picture are the OEM US Spec that were swapped out for the MK7.5 by shopdaps version. They were coded to have dynamic turn signals which work fine right now. The adaptation settings I've checked were lastyp channel 20 and 21 (these are supposedly the right outer and left outer channels). What channels do you want screen shots of? This light I am assuming is the brake light (but just partially lit up as the whole brake light includes the middle and top strip of LEDS? |

vivi11: Are the new tail-lights like the fittings HERE, or maybe HERE?
If so, the coding instructions for the brake lights are on Leuchte21BR RC8 and Leuchte20BR LA71. Post-up screenshots of these Leuchte-sets on this car. To be clear, I need to see ALL 19 x channels for each Leuchte-set in your pictures

hmm.... I'm on the other side of this fragile blue planet, trying to help - but I need to understand the situation with your car to do that!
You really do need to be more diligent in your responses if this is going to work - else, let's just cease our conversation and hope that another forum member will be more tolerant!!!
Please answers my questions in my last post and please post the values for the rest of Leuchte20BR LA71.
Also, it appears that Leuchte21BR RC8 is disable! Why?
Please post-up the coding instructions for your new tail-lights

Don I am trying to be as detailed as possible. This is my first time dealing with any sort of coding for the car. I posted screen shots of 19 values for Leuchte20BR LA71 and 19 values for Leuchte21BR RC8. What other values are you looking for? Please let me know. As far as the coding directions, I do not have them. I purchased this car 2nd hand. Previous owner installed these. I know the Harness is shopdap, The website/youtube video from DAP has coding for MK7 to MK7.5 lights. Im not sure if this is the same as MK7.5 to MK7.5. Will post pics of the settings he has for those. How do I know Leuchte21BR RC8 is disabled? What is telling you that? Here is the typed out version. Is this what you are looking for? Will provide what I can.

OK - there are 2 x versions of LEUCHTE21BR RC8 and LEUCHTE20BR LA71 in your last post; one version with typed values and another version with screenshots! The different versions have different values for the same Leuchte-set.
I don't know what the different versions refer-to, so I have to again assume; I'm guessing that the screenshot version is the actual values in this car - is this correct?
And perhaps the typed versions are the instructions, maybe - but I'm not sure? If so, why are the coding values in the 2 x versions different?

After more research, the pictures of the coding instructions for the tail lights that are I added are for the MK7 and not the MK7.5. I pulled those from a YouTube video but those are irrelevant.
The typed values are the current values on the car.

vivi11 : Of course I'm willing to help - it's what I do on this forum (with varying degrees of success)!!
So - I'm still trying to understand your responses - you didn't answer my previous question about which lights are installed on this car!
Don't worry that the car is RHD - but is the GIF below how these tails are meant to operate (note the difference in the illumination pattern on the outer fitting between Parking Light (I think Americans call these "position lights") and Brake light functions)?

Yes that is how the tail lights are supposed to operate. My reverse currently do not light up and I think it was because the previous owner wired it incorrectly somewhere. However, I am more concerned about the outer piece that I mentioned being lit up during the day at all times. It needs to stay off. Here is the picture of the type of tail lights. They are from shopdap. Do you have an email to send how the tail lights currently function? I made a video when braking, reversing, headllights off, headlights on.  |

vivi11 : As I indicate on the signature for my posts, the best place for these discussions in in the forum proper (I prefer NOT to use PM, or Email). I've done some further research on the DAP harness - see Here. I'm not sure if your car is a NAR model - but the .pdf coding sheet from zero815 can be downloaded here
So, what's clear from the suggested coding is that the Leuchte-set for the right-side brake-light (Leuchte 21) is meant to supply permanent +12V to the LED circuits inside the new fittings - because Leuchte21BR RC8-Lichtfunktion A 21 > Klemme 30 G
Because you say that this light is always-ON, I suspect that it is in fact coded as per the DAP instruction (I don't know why your previous screenshots for Leuchte 21 are different).
If I'm correct (and I'm again guessing), then the fact that Leuchte 21 now provides permanent +12V to the right-side lights means that there is a problem with the way that the harness has been connected. With the harness correctly fitted, the wire for the old right-side brake light should have been re-routed to the internal circuits that run the new lights. But it appears that the harness does not do this - I think

Lets say I wanted to fix the issue by installing the USDM SPEC tail lights back.
What settings are 'stock' in this case to have those function normally?
With these tails being 2nd hand, do pins get removed from the original OEM connectors to the new harness? Wondering how simple it is to go back to stock.

vivi11 : hmm....... Whilst I do have some NAR model cars in my MQB database, for obvious reasons related to the fact that I live in the very, very deep South and because US cars are very different to those in the rest of the world - I don't have a complete list of the settings for a NAR Golf R. But it shouldn't be difficult to get these factory settings via an intelligent search with Mr Google!
As for the physical install of "USDM SPEC tail lights" and AFAIK from my reading of the DAP material, there is no de-pinning on the factory connectors at the rear of the car (i.e. on the factory installed wiring loom). Again AFAIK, the DAP harness simply adds additional connectors to the original wiring which adds extra wires to the installation.
This means that it should be possible to "undo" the retrofit by disconnecting everything downstream of the original factory connectors on the 4 x tail-light fittings. Obviously the "undo" task also needs coding changes to restore the original settings in the central electrics module
Finally, a word of caution when buying "USDM SPEC tail lights" - despite the marketing hype on ALL webpages, the claims of third-party manufacturers that their fittings are OEM are seldom true - so, be careful choosing! And of course, make sure that you buy OEM fittings with the correct lamp type (i.e. incandescent, or LED) to suit the factory wiring loom on the car.
Don
PS: for others reading this response, I had to look-up the term USDM. It means "United States (of America) Domestic Market"
