Hi. So the VW Documentation refers to the 3 sockets as follows:
Left Socket A - 73-pin connector -T73a
Middle Socket B - 46-pin connector -T46b
Right Socket C - 73-pin connector -T73b
So the right 73 pin connector is described as T73B connector while the Leuchte-sets naming is Cxx.
Have no idea why...
Looking at the various schematics where different control units have 1 or more cables going to the BCM 73B socket they all show the T73B naming.

hi, you are confirming something that had also occurred to me, that is, the BCM has 2 connectors of 73pin, one was called A and one B. But now I don't understand why my Golf already has cables on pin 35 and 61 of socket C (T73b) and furthermore if I connect the LED bar to those cables, the LED bar does not work even though I insert the Leuchte 31/32 coding described here.
I'm seriously thinking of using the 12V cigarette lighter socket.

hi, I didn't receive any type of error coding C61 and C35 while the coding on B20 and B32 was not accepted. Other electrical cables are already present on pins C61 and C35 (curiosity, these cables are the same color as the VW diagram, i.e. yellow/white and yellow/black). I haven't checked pins B61 and B35... where can I find them? on socket A of the BCM? because socket B (the central one) is 46pin. Thank you So, I managed to get the mk8 Wiring Diagram ( WD) - here is a copy of the Light-bar wiring from the VW document: The picture clearly points to J519, Socket B - but the WD says that this connector has a total of 73 x pins! The WD confirms massimo23 advice in his earlier post! However, when I look at the VW document titled "Connector views: parts with prefix J" - it lists 3 x sockets as follows:
Onboard supply control unit -J519-- Chapter 46-pin connector -T46b-
- Chapter 73-pin connector -T73a-
- Chapter 73-pin connector -T73b-
Oddly, there is NO "73 -pin connector - T73c-" in the list and the B socket is listed twice with different total-pin counts!! And, to make matters worse - the VW document shows pictures of ONLY 2 x sockets (again, NO picture of "73 -pin connector - T73c-" and socket B is mentioned twice, but only one picture of socket B is provided).
The picture for the B socket shows a 46 x pin connector which is consistent with descriptor for socket B in other parts of the mk8 documents (it's also consistent with the pin-count on MQB platform models). So, I'm fairly confident that socket B on a mk8 version of J519 does indeed have a 46 x pin-count (which agrees with your observation). I've included the J519 socket diagrams below (without socket C, of course - because it has been omitted from the original VW document)
J519 Sockets - pin-out numbering:  So - what to do with the mess that appears to be the result of the official VW material? If we assume that the actual pin #61 & pin #35 in the WD is correct - then we must conclude that either:
- the socket identifier is wrong (i.e. it should read socket C), or
- the pin-count on the stated socket is wrong (i.e. it should read 46)
If option 1. above is the problem -your observation that "electrical cables are already present on pins C61 and C35 (curiosity, these cables are the same color as the VW diagram, i.e. yellow/white and yellow/black)" is interesting.
My experience with VW is that no more copper than is absolutely necessary is included in their cars. So, if this car didn't have the light-bar factory built and if option 1. above is correct - then I would expect the J519 pins C61/C35 to NOT be populated with wires! But you say that the wires are there and they are the same colors as in the WD!! So maybe look for the possible termination of these wires on the TIUL coupling point (i.e. the T17e/T17l connector in the WD above) - see a picture of the pin-out below.
Is there a yellow/black wire terminated on pin #7 and a yellow/white wire terminated on pin #5?
For option 2. above - I guess you need to identify if J519 socket B (46 pin-count) is populated with wires on pin #61 & pin #35!!

EDIT: further investigation onto the suite of mk8 wiring diagrams : I cannot find any mention of a C Socket with 73x pin-count on J519 in the official WD. So, the logical conclusion (for me, at least) is that there is NO -T73c- connector on this car.
So, bottom line = Golf mk8 evo platform models have TWO x Socket B connectors on J519 - one has a 73 x pin-count and the other has a 46 x pin-count (but both are designated as Socket B in the WD).
This means that when the coding identifies Leuchte 31 AMBL 1 C61 and Leuchte 32 AMBL 2 C35, the physical locations that these Leuchte-sets actually control are pins #T73b /61 and pin #T73b /35, respectively.
Go figure - I never cease to be amazed by VW nomenclature!!

as previously mentioned by massimo23, the BCM mounted on the Golf 8 has 3 sockets identified with the letter A,B,C printed directly on the BCM port. port A (on the left) has 73pins, the middle port (B) has 46pins and port C (the one on the right) has 73pins. As said by massimo23, the 73pin socket A in the VW wiring diagrams is indicated as T73a, while the 73pin socket C is indicated T73b. As already mentioned before, pins C35 and C61 on socket C (T73b) are already occupied by other cables of the same color as the VW diagram regarding the LED bar and unfortunately, being rolled up in a black gasket, I can't see where they end up (however I don't know where I should look for the 17pin TIUL connector). Furthermore, the 46pin socket B indicated as T46b having only 46pins, pins 35 and 61 do not exist here and therefore the LED bar cables certainly do not connect to the 46pin socket for Golfs after 48/2020.
How to get out of this absurd situation?
Thank you.

You're struggling for nothing.
No one has ever connected with proof that it works like a factory installed car. Connect to the 12v wire and put the fuse. The strip is activated when the car is started.
Listen to this simply, if you continue to fantasize with the processor you can easily burn it

however I don't know where I should look for the 17pin TIUL connector This diagram shows the location of the 2 x 17 pin sockets on the TIUL coupling connector for a mk8
You're struggling for nothing. No one has ever connected with proof that it works like a factory installed car. Connect to the 12v wire and put the fuse. The strip is activated when the car is started. Listen to this simply, if you continue to fantasize with the processor you can easily burn it : Hi.
Clearly this is a decision for OP - but I understand your point!! That said, I don't quite understand your concern about "you can easily burn it" - I assume you mean the "processor", which again I assume refers to the internal circuitry in the central electrics module. If so, I'm not sure that this is a reasonable risk in this case. The circuits behind the Leuchte-sets that provide power to each of the external lighting pins on the central electrics module are very robust, electrically. Unlike the traditional way of designing car lighting circuits -the external light circuits in these new cars do NOT contain in-line fuses. Instead, the central electrics module in these cars separately monitors the electrical lighting load on each individual pin - and these circuits contain a protection facility that is capable of detecting and isolating faults as severe as a shot-circuit!! So, the internal circuits behind Leuchte-sets are self-protective, they act like a circuit breaker - and they have an automatic reset ability when the fault is cleared. Now of course there are limitations to the situations that can cause the internal protection circuits to fail. But, with no offense intended - I respectfully suggest that the risks of "burning it" as a result of adding a LED strip to the central electric module is probably very minor!
In the alternative, if you mean ""you can easily burn it" referring to the LEDs themselves, then the semiconductors in these items are protected by a load limiting ballast (usually a resistor) and reversing the leads shouldn't cause any damage because they simply won't conduct! So, again without intending any offense - very low risk IMO. Don

The pins for the FLB are on the C connector of the BCM. In my case I had the respective pins already occupied, leading to the TIUL connector. Either unpin those or connect yout FLB connectors to the TIUL connector.
If you have issues coding it, a FW update to the BCM might be necessary

 Here is the photo of the TIUL as indicated to me. The cables of pins 35 and 61 of socket C of the BCM (T73b) are connected to pins 6 and 7 of the TIUL as seen (I hope) in the photo. What can this make us understand? Thank you. |

silvano86 : arrhhhh........ the plot thickens!!! So, if understand correctly - it appears that on this car, VW has provided copper wire for the LED bar from the central electrics module to the TIUL coupling block.
 Referring to my WD again and once more if my understanding is correct - I assume that you have found that there is a yellow/black wire on T17l pin #7 and a yellow/white wire on T17l pin #6 (I can't see the pin numbers on your picture - but doesn't matter).
I also assume that you have found NO wires connected to the mating pins on the other side of T17l terminal block - which is T17e in the WD. If so, this means that the proper point to attach the yellow/black and yellow/white wires FROM THE LED BAR is on the mating pin positions #7 & #6 of T17e. Of course, the earth wires also need to be connected to the LED bar to complete the circuit.
However, if you have found yellow/black and yellow/white wires on pins #7 & #6 ON BOTH T17l and T17e - it means that there will be 2 x two-pin connectors for the LED bars in the engine bay (somewhere)
Also, please post-up screenshots of either Leuchte 31 AMBL 1 C61, or Leuchte 32 AMBL 2 C35 so that I can look at your coding. To be clear, I need to see ALL adaptation channel values of the Leuchte-set in your pictures

That's right, on the other side (T17e) there are no electrical cables continuing. But if I have already connected to the yellow/black and yellow/white cables directly on the BCM socket and it didn't work (despite the Leuchte coding), what changes if I connect to the T17e socket? Maybe the problem lies in the coding. this is the original one currently present on the BCM:

That's right, on the other side (T17e) there are no electrical cables continuing. But if I have already connected to the yellow/black and yellow/white cables directly on the BCM socket and it didn't work (despite the Leuchte coding), what changes if I connect to the T17e socket? hmm.......... OK - maybe put yourself in my position and ask this question again! Remote diagnostics via a forum like this is a tricky thing at the best of times and it certainly doesn't help that I don't have access to this car in my workshop!! So, in an effort to understand stuff that probably is happening on the other side of this lonely blue planet - I have to entertain possibilities. An obvious "possibility" is the question: why didn't your initial attempt work (which involved splicing into the BCM socket)? Now, I don't know the answer. However, when choosing options in these type of projects, I ALWAYS (emphasis on "always") prefer OEM solutions and OEM fixings - meaning in this case, OEM pins inserted into OEM coupling connectors. My experience has been that using OEM fixings at OEM fixing points is far superior; they tend to work and they tend to stay working over time (but this is my opinion)
I've no doubt that your skills at splicing wires into factory looms are far better than mine - but I know from bitter experience the difficulty of making sound electrical connections where space is limited and were many wires are packed close together. So, the short answer to your question is: Yes, of course there is no electrical difference between splicing into the BCM socket wire and connecting at T17e. However, my suggestion wasn't motivated by electrical concerns - I was more interested in eliminating a possible reason for the failure of your first attempt at a solution
In any event- it really doesn't matter from my perspective where the connection for the LED bar is made on this car - this decision obviously is entirely yours!!
Maybe the problem lies in the coding. Yes, "maybe" indeed!! Try this: Leuchte 32 AMBL 2 C35 and Leuchte 31 AMBL 1 C61 - Lasttyp > LED Kleinleistung
- Lichtfunktion A > Ambientelicht 2, or Ambientelicht 1
- Dimmwert ABC > 100

Good evening and Merry Christmas everyone.
I finally managed to try these two encodings but unfortunately neither of them works, in fact the encoding with the value "Lasttyp > LED Kleinleistung" is not accepted.
Do you have other solutions/ideas?
Thank you!

Post by dv52 (Australia) on Dec 25, 2023 20:52:08 GMT
Yes, season's greetings totally reciprocated!! hmmm......."neither of them works" doesn't provide much feedback to remotely understand what exactly happened! did massimo23 suggestion result in error messages when you tried various lighting functions? Why did my suggestion Lasttyp > LED Kleinleistung result in "not accepted"?
I can understand if after coding the entire Leuchte-set an error message results -but simply selecting an option from the allowable list of values when coding a single channel and getting a "not accepted" error message means that the local coding environment was deficent- it does NOT mean that the coding value is incorrect! If you want further evidence of my contention that the coding value in my suggestion was NOT wrong - I provide an example of how Leuchte 32 AMBL 2 C35 and Leuchte 31 AMBL 1 C61 is actually factory coded on a real mk8 where these Leuchte-sets are activated from the factory - look at the adaptation channel map (called an "admap") from a VCDS device HERE If you are not aware, VCDS reports adaptation channels like this: - ENG263445-ENG116461-Leuchte 31 AMBL 1 C61-Lasttyp 31,LED Kleinleistung ,20
The VCDS entry above has a Comma Separated Variable (CSV) format where the data fields are separated by a comma. The format is decoded like this: - Primary Tag-Secondary Tag-Channel Name,Channel value,Channel Bit length
Here's an extract from my link showing an actual factory coding for Leuchte 31 AMBL 1 C61
Again, the coding values in my table and in my link are factory settings - notice that: Leuchte 31 AMBL 1 C61-Lasttyp 31> LED Kleinleistung!
So once more, your perfunctory observation "in fact the encoding with the value "Lasttyp > LED Kleinleistung" is not accepted" tells me that the local conditions in your attempt to code these channels was incorrect. I don't know why the conditions for your coding attempt was incorrect. Maybe more words in your reply would help in this understanding - but this is entirely your choice, of course!!
Anyhow, I'm out of suggestions - good luck with the rest of your project!!
Don

Good evening, thanks for answering me! When I wrote that the value "Lasttyp > LED Kleinleistung" is not accepted, I was obviously referring to the entire encoding of all values, i.e.
Lasttyp 31:
LED Kleinleistung
Lampendefektbitposition 31:
35
Fehlerort mittleres Byte DTC-DFCC 31:
26
Lichtfunktion A 31:
Ambientlicht 1 or Ambientlicht 2
Dimmwert ABC 31:
100
Lichtansteuerung HD ABC 31:
always
Lichtfunction D 31:
Exterior Environment 4
Dimmwert DEF 31:
100
Here this coding is not accepted, while the coding proposed by "massimo32" is accepted, it does not generate any type of error but whatever happens the LEDs do not light up. Furthermore, I also tried to measure with a multimeter (for each coding tested) whether there was voltage on the pins of the TIUL connector, but the result was always 0. I would also like to point out that, for the avoidance of doubt, I had no doubt in the slightest that the coding "LED Kleinleistung" was the result of an invention but rather of a real study based on reliable sources!
What can we do now?
What can I provide you to get a clearer idea for further coding?
Thank you!

- p Kessy ID:active
- PSO active participant ambient lighting exterieur enabled: active
- pa ambExtLight Installation: active
- pa ext Ambiente: active
Check these also:

- Bedingungen zur Standlichtbegrenzung: Switch-off due to energy management
- Bedingungen zur Parklichtbegrenzung: Switch-off due to energy management

- Standlichtreduzierung mit beidseitigem Parklicht: active
- Standlicht aus: active
- Parklicht ueber LSS aktiviert: One-sided
- Lichtwarnungsverhalten: klemmenabhaengig
Also the Led bar operate as parking lights so visible when dark.

hmm..... OK - so you didn't try my option then? I never suggested Lichtfunction D 31 >Exterior Environment 4, or Dimmwert DEF 31 > 100 in my option. These settings were in massimo23 suggestion and I assume that that these values are compatible with his Lichtfunktion A 31 > Standlicht. I have no idea how the Leuchte command Exterior Environment 4 interfaces with my suggested values for Lichtfunkion A > Ambientelicht 2, or Ambientelicht 1!
As for your question of the way forward, it really does depend on you. You could keep trying different combinations of massimo23 and my suggestions if you believe that this has a better chance of being successful. However, my personal experience has been that there is NO advantage in filling vacant Lichtfunkion channels with Leuchte-commands if not necessary. Again for what it's worth, my experience has been that every addition of a Leuchte-command to a Lichtfunction channel carries with it the possibility of conflict with one of the other Lichtfunction channels. But, my words are purely IMO only - you may well have a different view and after-all, this is your project!
In any event, I happen to be a great believer in keeping stuff as simple as possible. Again, this is your project- but if this was my car , my approach would be to get the AMBL Leuchte-sets working with a SINGLE Leuchte-command first - as proof-of-concept. Once this is achieved, I would try adding additional light-functions to the AMBL Leuchte-sets as a totally different and as a subsequent exercise
It really doesn't matter whether you use massimo23 option, or the suggestion in the Ross-Tech table as per the my last reply, Start by activating just the bare minimum parts of the AMBL Leuchte-sets - meaning activate the lamp set-up channels and just ONE Lichtfunfunkion channel with Dimmwert =100.
Then, try switching through ALL possible lighting functions with the ignition-ON (i.e, DRL, position-lights, low-beam, high-beam. If the new LED bar doesn't illuminate - grab your multi-meter and test for volts ON THE CENTRAL ELECTRICS MODULE PINS (again with the light-switch on ALL positions). If you don't measure any voltage - disconnect the LED bar and repeat the voltage test again - in full.
If you still have NO volts - then either the Leuchte-sets aern't activated properly, or something is amiss with the central electrics module, If you have used EXACTLY (repeat "exactly" for emphasis) the AMBL Leuchte-set values in the Ross-Tech table - then you know with absolute certainty that these are factory settings!! I'm almost certain that massimo23 option has also been taken from an actual mk8 too!!

I have completed this retrofit successfully on my mk8 golf r line. It can be fully coded via OBD eleven. This link has a step by step guide to install on how to complete it which was perfect. The wires are to be plugged into empty slots of the BCM (36 and 37). This works for the 2022 model which is what I have and should be fine for most others (maybe slightly different for 2021). Keep in mind the BCM is on the left side of the vehicle no matter if you drive LHD or RHD. acmtechnik.com/products/mk8-front-grille-light-bar-retrofit-harness |

Where did you all buy your led bar and Harness? Funnily enough I’m in Australia and ordered an OEM light bar directly from Ali Express and it was perfect. Didn’t expect that but it was great, they also had gti and r options too but mine was specific for the r line. It was a store called VW AG Store. It comes with the wiring, once you use the guide I linked it will work. If you don’t have one already you’ll need an OBD Eleven because it’s the only tool available that can unlock the SFD protection for coding. |

Hello
Does anyone have rough pictures after installing the wires?
