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)?

@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

@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)

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. And, the same happens during daytime - ALL the lamps fully illuminate! Is this road legal in Germany?

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!

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?
