VCDS (VAG-COM) codes and programmable options for Golf Mk7

[DV52]

OK - so first I need you to confirm that the 2 x Leuchte-sets that you posted do in fact control the inner - taillights.

If I'm reading your Leuchte-values correctly, these Leuchte-sets have the following light-functions:

1. Parking Light (position light)
2. Coming/Leaving home
3. Single Side Parking Light
4. Door Exit Light

Is this correct - do these 4 x Light functions currently operate on your inner tail-lights?

And just so I understand your wants (i.e. the colored markings on your original picture ), please also confirm that you want to keep the inner tail lights and have the outer tail-lights deactivated. Is this correct?

Also, the missing light function from my list above is the Brake light. I assume that the Brake-light operates on the outer tail light on each car-side on this car (this is the normal set-up for MQB platform vehicles). The Leuchte-values on your latest attachments are set to illuminate the 4 x light functions above at full brilliance. And almost certainly, the Brake light will also be programmed to illuminate at full brilliance.

Currently on this car there is no confusion regarding when the driver presses the Brake pedal at night-time (when the Parking light is switched-ON) because the tail-light position distinguishes the Brake from the Parking light - for drivers at the rear.

However, if the outer tail-light is deactivated and the Brake light function is transferred to the inner tail-light, divers at the rear of this car wont be able to tell when the Brake light is pressed (because the lamp will already be fully illuminated by the Parking light function)

So, we need to find another way to distinguish the Brake and Parking Light function with only ONE tail-light operating per car-side. The ONLY way to do this is to dim the Parking -light function so that full illumination of the tail-light lamp when the Brake pedal is pressed provides the required visual prompt to other drivers. Is this acceptable?

Finally, I also need to see how the Leuchte-set for the outer tail-light is programmed (I only need one car-side). Please provide screenshots.

Finally, finally - you have deftly side-stepped (read "not answered") my question about the road-legal status of this car in Italy with only ONE tail-light operating per car-side. I assume this omission is deliberate - and at the end of the day, this really isn't my concern - it's entirely your choice.

Nevertheless, given the importance of this legal matter and so we are both clear - I must advise that the FULL extent of accountability that I will accept for my suggestions is EXACTLY equal to the financial payment that I receive for providing said advice (which is precisely zero )

Hi Don,

The light of the

Brake is on the outside, that must work as original when I press the brake, I would just like to remove the two side lines that I highlighted in green (see attached photo). As for the legal part, the external light I can turn off the position lights without problems, you have no responsibility for this. Now I am attaching the data of the control unit you requested.

Postscriptum

(I see that you are very informed, where can I find this information on how to read the data of the “leuchte”? I see a lot of numbers and a lot of addresses and some wording in German)

Thank you

hmmm......... OK, I think we may have a problem communicating. I'm not sure if it's a language thing - Italian is my second language and I suspect English might be your second language! But your English is far better than my Italian- much to the chagrin of my parents!

Anyway, because Leuchte20BR LA71 and Leuchte21BR RC8 in your last post contain the Leuchte-command for the Brake-light function, I now suspect that these Leuchte-sets relate to the inner tail-lights in your picture.

So, are you saying that the outer position lights on this car are assigned to Leuchte18BLK HLA60 and Leuchte19BLK HRC31?

Please confirm that the outer tail-lights (the lamps that you identify as "Remove this Taillights" in your picture) operate as the following light-functions:

1. Parking Light (position light)
2. Coming/Leaving home
3. Single Side Parking Light
4. Door Exit Light

Is this correct - do these 4 x Light functions currently operate on outer tail-lights?

PS: A tutorial on Leuchte-programming is well beyond the scope of these replies.

I have built a "virtual MQB platform car" which currently lives on my work-bench (see below) - it's constructed with a bunch of 2nd-hand control modules that I have wired together in a spaghetti manner!

I occasionally use this to teach Leutche-prgramming to others -my "students" are free to make whatever changes they want without the risk of breaking a real car. No one has broken my test-bench yet - notwithstanding that many have tried (I've seen some very innovative examples of Leuchte-programming).

You are welcome to join their numbers if you ever make it down here - albeit, I suggest that there are far more enjoyable ways to spend your time when visiting Australia !!

Ok I confirm leutche 18 and 19 are external, while the internal ones are 23 and 24 and I confirm the operation of those

External as you listed.

Note: I've highlighted Dimmwert CD above. The value in this channel determines the illumination level of the lamps in Parking Light mode - not sure if Italians call these "position lights"? Dimmwert CD = 28 is a guess!!

I suggest that you experiment with this value for the particular LEDs in your tail-light fittings (the efficiency of photon production at various dimming levels can vary substantially across different LEDs). Find an acceptable Dimmwert CD number that yields sufficiently high illumination for the Parking light mode while also being dim enough so that cars at the rear can distinguish when the driver presses the Brake pedal. Of course, the best way to make this judgement is by experimenting during night-time conditions

Don
PS: I've tested my suggestions above on my test-bench - works OK!!

[samusi1]

I tried your configuration, so the external part turns off completely, (the one in the black circle) I would have liked to turn off only the two external LED lines and leave the third remains on the brake light at intensity 28

I leave you 2 photos to make you understand, I would like as in the yellow circle for the position lights (at this point I believe that the external position lights turn on or off all together without the possibility of dissecting them)

@samusi: OK - that's why I asked:

Please confirm that the outer tail-lights (the lamps that you identify as "Remove this Taillights" in your picture) operate as the following light-functions:

1. Parking Light (position light)
2. Coming/Leaving home
3. Single Side Parking Light
4. Door Exit Light

Is this correct - do these 4 x Light functions currently operate on outer tail-lights?

So, here's the thing about Leuchte-sets on MQB platform cars (like your Golf) - each individual Leuchte-set controls a single pin on the module that OBD11 calls central electrics. This means that a single Leuchte-set controls the single wire that is connected to this module pin at one-end - and at the other-end, is terminated on the single pin on the tail-light connector.

Apparently on this car, that tail-light pin is internally connected to the 2 x lamps on the outer fitting (as you show).

Bottom line - To get your wants, you need to open the outer tail-light fittings and physically remove the link to the unwanted lamps!!! This aspect of your question is NOT a coding matter

[samusi1]

Ok, most likely I have to give up, what a pity, you were still very kind and exhaustive in helping me.

I want to ask you one last thing, do you know how I can enable the closing of the electromechanical tailgate with the
Keyfob? For now I can only close it from the button on the tailgate or inside the cockpit. I can only open it with the remote control


2nd question

Is it possible to make the front turn dynamic by not having the Matrix LEDs?
Thank you Don

@samusi: The tweak for tailgate is like this:

1. Fire-up OBD11 and connect to the dongle
2. Select the central electric module
3. Select adaptation
4. Enter "zv" into the search box and select ZV Heck
5. Select Freigabenachlauf Heck nach Einzeloeffnung ueber HDF-Funktaster and change to active
6. If asked for a security code - enter 31347

I don't understand your front turn signals question - maybe try again but using more words (are your front turn signals dynamic?)

Don

Hi Don, unfortunately it didn’t work, everything remained the way it was before
