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

[yorky]

Hi All, I had an idea (that may not work hah), is it possible to have lights come on, for example reverse lights, when the ignition is off, and you turn the indicator on? As this would trigger the side parking lights, is there a separate setting for this that would work (like left parking light) rather than just parking lights (so that the reverse lights don't come on with normal parking lights)?

[DV52]

@yorky: Great to read that you are creating "innovative ideas"!!


however.......... I'm not sure that I entirely understand!! The reverse lights can be used to illuminate with virtually ANY lighting function - including Single Side Parking Light (SSPL). And, it's also possible to delete the factory coded SSPL function from the normal "parking lights"

So, am I correct in understanding that your "idea" is to transfer the SSPL function from the parking lights to the reverse lights? If so, why do you want to do this?

For example, I'm not sure about this car - but if it has LED tail-lights, then your "idea" could mean that the SSPL function will use incandescent lamps at the rear instead of LED lamps (reverse lights on some OEM LED-fittings are incandescent). Ain't nothing wrong with this - but to minimize battery load when the car's alternator isn't working, the SSPL illumination level of the reverse light should be dimmed- I think

Thanks Don, you are correct, and just to illuminate the rear area more if I'm working in that area, however not for a great length of time, as you say, the battery won't be liking that! The reverse lights are LED I believe.

I've had a crack at it and put the left and right SSPL functions into the C channel of the reverse light, as well as the number plate, brake and rear fog light just to experiment a bit. They come on as expected when I flip the indicator left or right with the ignition off, and go back to normal parking lights only when the parking or headlights are turned on.

The only issue I came across, was the left reverse light triggers the reversing camera to flip out, and thus cancels the ability to open the boot! So I've only enabled the right reverse light.

Hey all,

First Post - I am currently looking into Coding in Adaptive cruise control on my 2017 MK 7.5 Golf Alltrack TDI - From what I can tell all I need to activate it is the proper button set for the steering wheel 5G0 959 442 R and OBD11 / VCDS coding to activate it. Has anyone here done this mod in the past know what code I need to use? I am looking to tuners / mechanics who have OBD11 experience but so far have come up dry.

Thanks

[DV52]

@poota91: Hi.
hmm...... so if I understand your words correctly (apology if I don't), this car currently doesn't have ACC!

If so, then I hate to be the harbinger of bad news - but retrofitting ACC to a MQB platform vehicle (like your Alltrack) ain't just a matter of coding changes and a button-set. ACC needs the fitment of a radar module (it's called "J428"), which is installed on the car front - not sure where it's placed on an Alltrack (I think it's screwed onto the front bumper-bar). The radar is the transducer that detects the speed of the vehicle in front- normal Cruise Control doesn't have this module

The second complication with retrofitting J428 is that the module has Component Protection - which is a kind-of anti-theft protection. Unfortunately, you will need to visit a registered dealer to authorize this module after fitment.

Maybe read THIS

Hi everyone,

I thought I'd give it a shot here as well, since it's a pretty big community and our vehicles are not that different, mine being a 2019 VW Passat B8 Kombi (euro model).

Hopefully someone can give me some help in achieving something that I find important (safety wise, as I believe that the existing vehicle configuration does not offer sufficient visibiliy while using the rear turn signals).

Like I said above I own a 2019 VW Passat B8 (variant/kombi) with LED headlights (the Low version, without projectors) and LED tail lights.

I do not have for the moment a VCDS interface, however, I do have a PLX Kiwi 3 OBD adapter that I bought many years ago that still works, and an app from iOS store that allows me to modify most of the lighting blocks as a VCDS one would do (AB, CD, EF, GH, along with their settings).

I have managed to enable the rear strips to work as DRL in “Auto” mode. Some sort of Scandinavian DRLs for the tail lights. As I did not had a VCDS to just tick a toggle for this, I had to do some changes in 4 blocks? (is this the right word?) combining a miriad of sources from various forums and groups online.

The modified blocks were:

The inner part

Leuchte16BLK SLB35BLK
Leuchte17TFL R BLK SRB3TFL

and the outer part

Leuchte23SL
Leuchte24SL

So far so good. The rear DRLs are always ON while the the switch is in the “Auto” mode.

In addition to the above, what I want to achieve is something like US style turn signals, BUT, keep the rear DRLs at a lower intensity between the flashes, otherwise the tail light will be absolutely blank/dark for a fraction. This in addition to the yellow/amber turn signal that must go with the DRLs.

This video, though on a different car, does what I want to accomplish.

My current setup with the light switch in either position (O, Auto, parking lights or low beam):



Turn signals with DRLs ON in any light switch position (click the link below for the video, I tried to embed it but the function covers only YouTube videos I assume)

https://i.imgur.com/TQrKvWj.mp4

and here is a current setup of the blocks

Leuchte16BLK, Leuchte17TFL for the inner part and Leuchte23SL, Leuchte24SL for the outer part. I had to combine two screenshots for each block, as one would not cover all the options.









Sorry for the long read. I did my best to offer as many details as I could.

Many thanks,

Dan

Dan: Hi.
Excellent first post - a good example of the principle that too much information is never enough when asking questions on a forum!!

However, I need more words to understand your needs. I get-it that you want the lamp not to fully dim between flashes of the turn-signal. But do you want this lighting effect to apply to the turn signal lamps in the video of your car? Or, do you want the lighting effect to apply to the lamps in the "blocks" (let's call these "Leuchte-sets") in your table. And if the latter - which lamps on the tail light fittings?

Finally- I note that you have chosen to apply FULL illumination for every active "Function" (let's call these "Lichtfunktion") in the 4 x Leuchte-sets in your table. I'm not sure how the left/right Leuchte-sets for the Brake lights is programmed on this car - but I suspect that these lamps are also fully illuminated.

This means that after dark when the Parking Lights (maybe you call these "Position Lights") are turned-ON with the low-beam lights - the lamps at the rear of this car are ALL illuminated at the same intensity - including the Brake-light. And, the same happens during daytime - ALL the lamps fully illuminate! Is this road legal in Germany?

I ask because the normal factory set-up is for the Parking Lights (PLs) to be dimmed - so that drivers at the rear get a very clear signal when the Brake pedal is pressed (i.e. normal factory arrangement is that the Brake-lights are the ONLY lamps in the tail-light cluster that fully illuminate)

Hi DV52,

Many thanks for getting back to me. First, I'll adapt my terms used for this.

However, I need more words to understand your needs. I get-it that you want the lamp not to fully dim between flashes of the turn-signal. But do you want this lighting effect to apply to the turn signal lamps in the video of your car? Or, do you want the lighting effect to apply to the lamps in the "blocks" (let's call these "Leuchte-sets") in your table. And if the latter - which lamps on the tail light fittings?

The dimming should apply only to the lamps in the "Leuchte-sets", the red LED stripes ("Parking Lights/Position Lights").

Finally- I note that you have chosen to apply FULL illumination for every active "Function" (let's call these "Lichtfunktion") in the 4 x Leuchte-sets in your table. I'm not sure how the left/right Leuchte-sets for the Brake lights is programmed on this car - but I suspect that these lamps are also fully illuminated.

I had to do this in order to have them light up during daytime, otherwise they wouldn't turn on until dusk when the light sensor kicks in and turns on the low beams.

This means that after dark when the Parking Lights (maybe you call these "Position Lights") are turned-ON with the low-beam lights - the lamps at the rear of this car are ALL illuminated at the same intensity - including the Brake-light.

Correct, with the exception that the brake lights have associated with two other LEDs within the lamp marked in blue (+ the central mounted lamp on the rear window). Those two brake lamps would work all the time as factory since they are independent.

One for each outer light.



It is road legal, yes.

A video of how the brake LEDs are configured for this vehicle. I apologize for the viewing angle, I had no better spot to place my phone to record this.

Video available at https://i.imgur.com/ZX2gYC5.mp4 ; low quality though.

Later edit:

Do you think a solution would be to change the "main" function of these 4 Leuchte-sets, make function A to be used as a turn signal left&right and have the DRL/Tagfahrlicht be active as a secondary function in one of the other channel subsets CD/EF/GH?

Give the turn signal the highest priority, followed by their original role of Parking light in general ("..."), DRL/Tagfahrlicht and so on?

Hopefully it makes sense.

[DV52]

The dimming should apply only to the lamps in the "Leuchte-sets", the red LED stripes ("Parking Lights/Position Lights").

Understood- thanks for clarifying!

I had to do this in order to have them light up during daytime, otherwise they wouldn't turn on until dusk when the light sensor kicks in and turns on the low beams.

hmm.............. with absolutely no offense intended - I don't think that your response is correct. With Leuchte-programming, there are certain Leuchte-commands that operate "when the light sensor kicks-in" and there are other Leuchte-commands that are independent of the light sensor. Whether these Leuchte-commands are dependent on the light sensor, or not - is NOT determined by the illumination level (i.e. the Dimmwert value).

It is road legal, yes.

Noted - this very important issue is of course your responsibility!

Do you think a solution would be to change the "main" function of these 4 Leuchte-sets, make function A to be used as a turn signal left&right and have the DRL/Tagfahrlicht be active as a secondary function in one of the other channel subsets CD/EF/GH?

OK - let's do it your way.

However, I suggest an alternative approach to your Lichtfunktion values:- currently you have programmed the active Lichtfunktion channels in the 4 x Leuchte-sets in your table like this:

• Lichtfunktion A > Standlicht allgemein (Schlusslicht; Positionslicht; Begrenzungslicht)
• Lichtfunktion G > Tagfahrlicht

With this set-up, the lamps that are controlled by these Leuchte-sets are illuminated whenever the ignition is turned-ON - this is irrespective of the status of the light sensor. A better (read "more elegant") method to achieve this same outcome is to use the Leuchte-command, Klemme 15 ohne Nachlauf.

As I'm certain you already know given your German language background, Klemm 15 = Clamp 15, or more appropriately using the terms of vehicle industry Standard DIN 72552 - Terminal 15 (T15). T15 is defined in DIN 72552 as a battery-rail voltage that is active whenever the ignition is turned-ON. So, this single Leuchte-command can be used to provide the same lighting effect in this case!

So- try this:

Left-side Parking-Light Lamps
Lasttyp > 43 - allgemeine LED
Lichtfunktion A > Blinken links Hellphase
Lichtfunktion B > nicht aktiv
Dimmwert AB > 0
Lichtansteuerung HD AB > Always
Lichtfunktion C > Klemme 15 ohne Nachlauf
Lichtfunktion D > nicht aktiv
Dimmwert CD > 127
Dimming Direction CD > maximize
Lichtfunktion E > Blinken links Dunkelphase
Lichtfunktion F > nicht aktiv
Dimmwert EF > 26
Dimming Direction EF > minimize
Lichtfunktion G > nicht aktiv
Lichtfunktion H > nicht aktiv
Dimmwert GH > 0
Dimming Direction GH > maximize

Right-side Parking-Light Lamps
Lasttyp > 43 - allgemeine LED
Lichtfunktion A > Blinken rechts Hellphase
Lichtfunktion B > nicht aktiv
Dimmwert AB > 0
Lichtansteuerung HD AB > Always
Lichtfunktion C > Klemme 15 ohne Nachlauf
Lichtfunktion D > nicht aktiv
Dimmwert CD > 127
Dimming Direction CD > maximize
Lichtfunktion E > Blinken rechts Dunkelphase
Lichtfunktion F > nicht aktiv
Dimmwert EF > 26
Dimming Direction EF > minimize
Lichtfunktion G > nicht aktiv
Lichtfunktion H > nicht aktiv
Dimmwert GH > 0
Dimming Direction GH > maximize

Notes:

• the dimmed illumination level in the off-part of the blink cycle is determined by Dimmwert EF. Adjust this value as desired
• To make the Parking-Light lamps "counter-blink", swap Lichtfunktion A and Lichtfunktion E values

I apologize for the confusion.

"...As I'm certain you already know given your German language background"

I do not have a german background though, just doing business here. The permanent/resident status is in another EU country.

Now, the GOOD news! getting back to your suggestion.

Here is what I obtained per your setup:

This test was one was done using a dimming value for E+F of 10 < I like it more this way.

This test was done using a dimming value for E+F of 26

Close-up test using a dimming value for E+F of 26

Works as it should! You are a wizard.

Two issues, if I may:

#1.

It seems that I have lost a function. The "Parking Lights/Position Lights" are no more illuminated when I open/close the vehicle (Coming Home/Leaving Home function), only the license plate LED bulbs are visible on the rear end.

#2

Later edit: something else I have noticed.

With the car being off and locked > hazard lights ON

Only the yellow turn signals are being triggered, normal behavior I assume.

This I find very important during night time if, for any reason I have a breakdown on a secondary road.

Can the "Parking Lights/Position Lights" be triggered as well?

[DV52]

Now, the GOOD news............Works as it should!

hmm......... Please understand that I'm a firm believer that how folk program their cars is their decision - but I invite that you consider an alternative view!

When I look at your videos, my primary observation is that there is lots happening on the tail-lights on this car when you activate the turn-signal function!! Many years ago (probably before you were born) - a very eager math professor tried to instill into my much younger brain the concept of a zero-sum-game, which can be also applied to lighting design IMO.

Not sure if you are familiar with game theory - but the concept when applied to lighting design ostensibly says that there is a fixed amount of attention that drivers at the rear of a car will use when reading tail-lights.

Importantly, the concept of a zero-sum-game says that different lighting designs CAN'T increase the total quantity of rear-car driver attention (it remains the same for individual drivers). Various different designs can only shift the amount of attention that the driver devotes to decoding each of the lighting functions on the tail-lights.

So, applying this theory to your video, my conclusion is that it's very unlikely that drivers at the rear of this car will miss your intention to turn left/right. However, I wonder whether in achieving this outcome, the obvious emphasis on turn-signal in this lighting set-up will overpower the Brake light?

Of course, each and every lamp illumination on the tail lights is important because it indicates the driver's intention to cars at the rear - but it could reasonably be argued that when comparing the priority of functions, the driver's intention to stop is the highest!

My question is particularly relevant (again IMO) in this case given that this design illuminates both outer and inner lamps at full illumination (i.e. the same illumination level as the single Brake-light on each car-side) and now the non-blinking Brake-light must also compete with the elevated emphasis on the turn-signal function!

Once more, entirely your decision - I'm highlighting the matter for your review!!

Two issues, #1.

It seems that I have lost a function. The "Parking Lights/Position Lights" are no more illuminated when I open/close the vehicle (Coming Home/Leaving Home function), only the license plate LED bulbs are visible on the rear end.

I'm confused! When I re-examine the Leuchte-set table in your previous post - I don't see the CH/LH Leuchte-commands on the PL lamps! Do you mean the Single Side Parking Light (SSPL) function that is enabled when the turn-signal stalk is activated prior to locking the vehicle? I ask because your table does have SSPL included on these lamps

If you want SSPL, do this:

Left-Side Parking-lights
Lichtfunktion G > Parklicht links (beidseitiges Parklicht aktiviert li & re)
Lichtfunktion H > nicht aktiv
Dimmwert GH > 127
Dimming Direction GH > maximize

Right-side Parking-lights
Lichtfunktion G > Parklicht rechts
Lichtfunktion H > nicht aktiv
Dimmwert GH > 127
Dimming Direction GH > maximize

And assuming that CH/LH has been correctly activated in the non-Leuchte channels on the hex09 module - if you also want CH/LH on these lamps:
Lichtfunktion H > Coming Home oder Leaving Home aktiv

#2

Later edit: something else I have noticed.

With the car being off and locked > hazard lights ON

Only the yellow turn signals are being triggered, normal behavior I assume.

This I find very important during night time if, for any reason I have a breakdown on a secondary road.

Can the "Parking Lights/Position Lights" be triggered as well?

So, here's the thing - the way that the hazard warning ights are operated on the VAG stable of vehicles is determined outside the scope of Leuchte-programming. By design (I think), if the ignition is turned-OFF and regardless whether the car is locked, or not - the hazard warning lights are dedicated to the factory blinker lamps (both front and rear).

There is a way of conjoining other lamps into this scheme - but in this case, we have run-out of spare Lichtfunktion channels because of the quantity of light functions that you have requested on the PL lamps.

However, I have just inputted this tweak into my "virtual mk7" (see below) and according to the behavior of the simulated lights on my test-bench, you should be able to trigger the hazard warning functions on the PL lamps if you turn the key to the ignition-ON position.

Alas that's the best that I can deliver -as I have said, the limitations of the Hazard lights are beyond Leuchte programming

[CSD]

Regarding #1


That did the trick for the Single Side Parking Light (SSPL)! Added your settings for all four Leuchte-sets (16, 17, 23 & 24). I know it's weird that they were not showing up before in my previous screenshots, yet, they worked for CH/LH.

Not sure if you are familiar with game theory - but the concept when applied to lighting design ostensibly says that there is a fixed amount of attention that drivers at the rear of a car will use when reading tail-lights.

I was not, but thanks for your suggestion, seems like a great topic.

So, applying this theory to your video, my conclusion is that it's very unlikely that drivers at the rear of this car will miss your intention to turn left/right. However, I wonder whether in achieving this outcome, the obvious emphasis on turn-signal in this lighting set-up will overpower the Brake light?

Maybe I am biased due to the fact that I owned most of my life USDM cars that worked in a similar fashion. Never had any issues or complaints, they were driven in Europe all of their life.


I will set up my phone tripod and re-create the video, with brakes applied. I am not sure why, but imho the actual brake LEDs embedded in the tail lights seem to illuminate way stronger than the DRL strips (even when set to have a 127 value).


I will decrease the values of the "Klemme 15 ohne Nachlauf", from 127 to 100.

The brake LEDs are also having a value of 127, along with the central brake light on tailgate.



Left-side Parking-Light Lamps
Lasttyp > 43 - allgemeine LED
Lichtfunktion A > Blinken links Hellphase
Lichtfunktion B > nicht aktiv
Dimmwert AB > 0
Lichtansteuerung HD AB > Always
Lichtfunktion C > Klemme 15 ohne Nachlauf
Lichtfunktion D > nicht aktiv
Dimmwert CD > 100
Dimming Direction CD > maximize
Lichtfunktion E > Blinken links Dunkelphase
Lichtfunktion F > nicht aktiv
Dimmwert EF > 10
Dimming Direction EF > minimize
Lichtfunktion G > Parklicht links (beidseitiges Parklicht aktiviert li & re)
Lichtfunktion H > nicht aktiv
Dimmwert GH > 100
Dimming Direction GH > maximize


I will do two videos for comparision to see if the 100 and 127 values make a real difference. My priority of course, is to focus the attention on the brake lights.

Regarding #2

Not sure why it didn't crossed my mind to leave the car in accessory mode. Maybe my worst case scenario was that I had to leave the car unattended with no occupants and locked. I believe there was a way to lock the car with the key inside and lock it with the spare key. But I think that was only with the engine running. Mine has a KESSY starting system.


I will edit this post once I do the videos.

Many thanks again for your time and knowledge.

Dan.

I feel that adjusting the 127 to 100 values doesn't do a difference. Maybe I should do a close-up video.

Filmed in 4K @ 60fps but YouTube doesn't show it yet. The lightning in the underground parking is also strange.

...
For those wanting to customise the instrument panel lighting by creating their own "dimming curves", I have written a short paper on how I developed the settings for these instructions. The document can be down-loaded HERE. Also included in my paper is a link to a spreadsheet macro that I created to calculate the settings for the "X" and "Y" values for this tweak. If you want to develop your own "dimming curves" then this spreadsheet might also be useful
...

DV52 - please could you provide an updated link to your document for dimming curves?

Hallo,
is this the coding where when the hazard warning flashes,the LED U also flashes on a golf 7 r model 2015??
If not,does anyone happen to know how I can get the LED to flash when the hazard lights are flashing.
Just like this police flashing headlights.
Iwould like to have that on my MK7R 2015 Europe version.
Kind regards from Germany
