Hello, I changed the rear lights of my vehicle. I want the lights on the trunk lid to turn off when it is opened. How can I do it with coding? 16:19 and 16:21 seconds of the video |

Michael, My assumption is that OP doesn't want the tail-light lamps on the inner fittings to illuminate the night sky when the boot-lid is up!!  Sounds reasonable to me - doesn't make sense for these lamps to stay switched-ON if the rear hatch is open! It's actually quite easy to code ANY of the the exterior lamps on a mk8/mk7 with this functionality because boot-lid conditionality is fundamental to the structure of a Leuchte-set. To explain- here's a comparative list of the Leuchte-set structures between the Golf mk8 and mk7:
On the table (which I first made to describe this stuff on the forum that I no longer frequent because I will NOT condone American gun culture) "MQB platform new" = mk8 and "MQB platform old"= mk7
Notice that ostensibly the two Leuchte-set structures are the same - basically the mk8 version has an additional Lichtfunktion channel for each of the 4 x Banks.
For the question of boot-lid conditionality - also notice that the bunch of Bank 1 channels do NOT have a Dimming Direction channel. This omission is common across mk8 and mk7 models. Instead, Bank 1 has the channel Lichtansteuerung HD
Because nothing official from VW about Leuchte programming is in the public domain, I don't know with absolute certainty - but my strong hunch is that Lichtansteuerung HD is German short-hand for Lichtansteuerung HeckDeckel. or in English Rear lid light control.
There are only 2 x allowable settings for Lichtansteuerung HD:
So with Leuchte programming - it's possible to enforce boot-lid conditionality for any light function that is placed in the Bank 1 group (on any external light that uses a Leuchte-set). It's that easy - as per 0lacetti suggestion !!

Hi Don: The little critter is a Virginia Opossum ( Didelphis virginiana), the only marsupial extant in the USA and Canada. I live right at the very northern range of their habitat (they are tropical animals) - they are quite rare in Canada. The picture is of a juvenile (joey). Michael |

OBDeleven_Log.txt (119.32 KB) Hello friends, I made the relevant change but it did not work. It continues to come on when the trunk lid is open.

Michael- OK , I didn't know about the Virginia opossum - apparently it has opposable toes on its two back feet (I'd like to have opposable toes!!) Because you showed me yours - I'll show you mine!! Australia's equivalent is Trichosurus vulpecula, from the Greek for "furry tailed" and the Latin for "little fox". 
Which of the two opossums is the cute-er? Don

After coding the lights, you need to close the car for 5 minutes.

After coding the lights, you need to close the car for 5 minutes. Hello 0lacetti, Yes. I know that 09 module on the MQBEvo (despite the MQB platform) needs to go thought the sleep 10-15min, at least for the changes on the lighting channels. OR you can use the Soft reset option which it's same as switch ignition off and wait until car goes to sleep.  More details in the below thread: forum.obdeleven.com/post/916/threadMy theory still stands, at least for SK Mk4, the channels are different. |

djmartzian : Of course anything is possible - BUT, I very much doubt that Leuchte-programming is "different" on a SK Mk4. There can be many reasons for your tweak not working - but again, it ain't because Leuchte-programming is "different".
If you want to continue to pursue this matter, I suggest that you post-up screenshots of one of the Leuchte-sets (doesn't matter which one) on this car. To be clear, your pictures should show ALL 23 x channels for the chosen Leuchte-set! One of the issues when coding exterior lamps on MQB/MQB-evo platform cars is making sure that the correct Leuchte-set is selected. A Leuchte-set controls ONE pin on ONE of the sockets on the central electrics module.
The name of the Leuchte-set identifies this pin/socket number. For example, in 0lacetti advice, Leuchte 28 RFL L C11 controls ONLY pin #11, Socket C on the 09 module.
With absolutely no offense intended to 0lacetti , this means that the underlying assumption for this tweak is that the lamp on your model car is factory wired to pin #11, socket C (and this may well be true). However, I know from a long experience reading VAG wiring diagrams that often many wiring changes are made for the same model car depending on its build date and depending on the type of tail-lights installed.
So, my words above lead me to ask: given that the tweak has NOT worked - have you confirmed that you have selected the correct Leuchte-sets for the lamps on the boot lid for the build-date of your car and for the type of tail-lights that were factory installed?
Of course, the best way to confirm the correct Leutche-set is to refer to the official wiring diagram for this car. However, if you don't have access to the wiring diagram - a useful trick is to temporarily disable one of the lighting functions on the Leuchte-set. This can be done by setting the appropriate Dimmwert value to zero
With this change made, the lamp should NOT illuminate when the lighting function is switched-ON - if the correct Leuchte-set is selected. If this does NOT happen (of if another lamp does NOT illuminate) - the wrong Leuchte-set has been selected!

I'm afraid I don't have access to the wiring diagram for my car. Really appreciate your effort on the community. Keep up the good job! |

On the Octavia a8, the lights are controlled by a LIN bus. There is a completely different logic of work.

OK - Thanks for posting-up the Leuchte-set (and for your generous words)
I've greatly truncated your post above to show only the relevant details. Notice from your records that this Leuchte-set has only ONE light-function -which is coded onto Lichtfunktion A as the Leuchte-command Rueckfahrlicht (ALL the remaing 11 x Lichtfunktion channels in this Leuchte-set are disabled because they have the setting nicht aktiv) Also, Rueckfahrlicht means Reversing Light.
So, if you changed Lichtansteuerung HD ABC to only_if_closed on this Leuchte-set - the affect on the inner tail-light cluster would be that ONLY the lamp for the reverse-light would NOT illuminate when the boot-kid was open.
Or said another way: with the changed value in this tweak - ALL of the lamps on the inner tail-light fittings except the reverse lights would continue to illuminate when the boot-lid was open. Was this your expectation (and your observation) when you completed the tweak? Don

On the Octavia a8, the lights are controlled by a LIN bus. There is a completely different logic of work. 0lacetti : Thanks for the information! I assume that the central electrics module on the A8 does NOT use Leuchte-sets to control the lamps in the tail-lights So, are you saying that on a A8, the master LIN module for the 4 x tail-light fittings is J519? If so, do the 4 x tail-light fittings share the same LIN bus - or does each individual fitting have its own LIN bus? I guess that using LIN protocols for comms with the tail-lights saves on the amount of copper in the wiring loom to the rear of the car - but it does mean that the tail-light fittings become more complicated (and therefore more expensive to manufacture)!!!
It's not clear why LIN technology would be applied to a function as simple (and as slow) as tail-lights - maybe the cost of copper is approaching a level where the savings in manufacturing costs now makes LIN protocols for the tail-lights viable?

There are 7 flashlight patterns. To determine the exact circuit, I need PR codes.

![]() Hello guys, I've found the wiring diagram. Hopefully these screenshots will help us to clarify the mistery: The arrangement is exactly as 0lacetti advised - these tail-lights use a combination of LIN based communications and direct wiring (for T58 & T54 functions - not sure what "BL" is)
So, the more interesting revelation given your wiring diagrams is that whilst these tail-lights use a LIN wire - they appear to also use Lechte-sets because Leuchte 29 RFL R A64 that you posted previously has been factory enabled. Fascinating stuff!!!
I'm guessing of course -but I wonder if the Leuchte-set values somehow code the LIN based messages on the LIN wire? Maybe 0lacetti can comment?
If you change Lichtansteuerung HD ABC 29 to only_if_closed - does the reverse light on the inner right-side tail-light fitting switch-OFF when the boot-lid is open?

Hello dv52 (Australia), First of all, apologies for my late response, but from unknown reason I missed you message. I'm afraid I didn't test the reverse light at the time of coding because I didn't know the channel being in use. Because the actual results was different to expected one, I reverted the coding afterwards (I'm always following the same principle with coding that aren't working, because I don't want to create unexpected behaviour with may car at some point.) Keep in touch |

Good morning. First of all, I would like to point out that I write in Polish and translate it with Google translator so I apologize in advance for any mistakes and I hope you will understand me. I am a user of Cupra Formentor MY2023 and I am looking for the coding responsible for the license plate light when the trunk lid is open, because when I open the hatch, the license plate light turns off. Will it be appropriate to change the Lichtansteuerung HD ABC 29 coding to only_if_closed to always? |

karol1974 : Hi. I don't have a wiring diagram for an EU model MY23 Cupra Formentor - but for the Golf mk8 equivalent, the license plate lights are connected to pin #59, Socket A on the central electrics module (according to my wiring diagram, the Golf mk8 has 2 x license plate lamps). This means that the Leuchte-set for these lamps on a mk8 is Leuchte 25 KZL H A59. So, maybe it's the same on your Cupra (I don't know)? Anyway - I suggest that you check the setting for Leuchte 25 KZL H A59-Lichtansteuerung HD ABC 25 on this car - if the existing value is only_if_closed - change to always

Sounds reasonable to me - doesn't make sense for these lamps to stay switched-ON if the rear hatch is open!
