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

[pinut]

hmm............... OK - your after-market addition is well beyond my feeble understanding of mk7 operations! I've no idea how J794 talks to your new head-unit - but clearly it's different to the standard MIB protocols where the "smarts" reside in the control module in the glove-box and the head unit is a simple screen (I believe that the comms between the two items are CAN based messages - perhaps your new "radio" doesn't accommodate these particular CAN messages?).

Has the retrofit resulted in any DTCs in your auto-scan report?

Unless someone else here has fitted the same aftermarket radio and they have found a solution to your exact problems (possible, but improbable- I suspect) , I suggest that you contact the equipment manufacturer

Don

Hi Don,

My apologies as I might not be clear enough.
The replacement radio is this below.
5GG 035 280 B - Google Search

Its actually a VW product.

Surprisingly there is no DTC after I swap this radio in.
Hence the curiosity.

Btw for this statement
Just re-implement the tweaks in your new "radio"
Can I clarify on this portion?
Do you mean I disable the menu items via VCDS and then re-enable it again to check if the menu will reappear in my new player?

Thank you.

Thanks Don, ill give this a go when I get a chance Correct car had halogens, the new headlights can take halogen or led for the lowbeams. the DRL are leds. VW Golf MK7 - Sequential Projector Headlights - Supernova Lighting If I dont have any luck with changing to LED, what else can I try? These are the current settings:

Hi there,

I too have recently purchased and installed these particular Headlights that Josh has mentioned. Although I can't help with his problem, my question is for Don, who I've seen as kind of a living legend when it comes to coding across many forums.

Firstly I have a Mk7 Comfortline which, as previously mentioned, originally came with Halogens. I have installed Supernova's LED headlights and everything works great out of the box. Sweeping sequential turn signals and all. Now, just to make sure we're on the same page, the light selector switch goes: 0 (off), Auto, Parkers(?), Dipped Beams.

When in the off position, the DRLs are on, full brightness.
When in the Auto position, the low beams are on, regardless of time of day.
When in the Parkers(?) position, the DRLs are on, full brightness.
And dipped beams, normal low beam again.

The factory halogens would, in the Auto position, have a DRL on during the day and automatically switch to low beam at night.
I am looking to regain this functionality with the LED headlights - Full brightness double "U" DRL during the day, automatically switching to low beam at night.

I have tried the "Tagfahrlicht nur in Schalterstellung AUTO" command and set it to active, but as far as I can tell, this only makes it so that in the "0" (off) position, then all lights are off (no DRL). With the Auto position still resulting in low beams during the day.

I saw your advice to change the Lasttyp's to LED, and will try this tomorrow, as it's night now and all testing is moot.

Thanks in advance.

whisp: "Don, who I've seen as kind of a living legend when it comes to coding across many forums" - pleeeeeeease don't say that - it's entirely incorrect and this particular legend (which I am NOT) most certainly does have feet-of-clay. I'm just an average Joe trying to make sense of how the good Burghers in Germany build MQB platform cars. The word "synergy" is a much over-used term these days - but it applies well in these forums because the (often small) contributions of individual members (like me) invariably results in the whole being greater than the separate parts! The true value is in the forum community, it's not in the participation of individual forum members!!

But enough of the hagiography - because I'm about to disappoint you: I don't know!!

As I have already said, 3rd party aftermarket headlights vary so much and the installation practices of their buyers can result in weird effects (no offense intended).

I assume that the auto-scan report on your car does not contain any errors and that you have made no changes to the code/adaptation-channels on any control modules following the retro-fit. If this is correct, I'm tempted to suggest (and by this I mean -I guess) that the behavior of the fittings is related to a wiring/physical-connector problem. Again, as a total guess, I suggest that you look at the interfacing connectors and confirm (i.e. look CAREFULLY at) the integrity of the pin contacts on both headlights - particularly the earth pin(s) on the connectors

Haha I appreciate your modesty. I only mentioned it because in the lead up and aftermath of purchasing and installing Head/tail/licence plate lights, I did a lot of research and you kept popping up everywhere. Always with helpful information.

I'm pleased to say the issue has been resolved. I had some time this morning and translated all of the options under:
Central Electrics 09
Adaptation
Daytime Running Lights.

I then proceeded to systematically go through all the options and try certain combos, but in the end, I just had to select the second "Daytime running lights" for the option "fahrlicht bei tag - Driving light during the day"

Hopefully this will help someone else out down the track.

German	English	Options
scheinwerfer ferreinigung sansteuerung und abblendlicht anzeige bei dauerfahrlicht	Headlight trailer cleaning control and low beam indicator with continuous running lights	Not Active Active
werkseinstellung fuer tagfahrlicht freischaltung BAP / bedienfolge	Factory setting for daytime running light BAP / operating sequence	Not Active Active

^^^ Well-done (my assumption regarding no changes being made to the control modules was clearly incorrect)!
Anyhow, in reciprocity for your kind words - allow me to elevate your standing (IMO) in the forum to "legend-status"

but seriously, alas it's a bit more complex than just picking the "daytime running light" option in the fahrlicht bei tag adaptation channel. I'm not sure if you are aware, but the same dichotomy (i.e. 2 x "daylight running light" options) also appear in the Lichtfunktion settings for the Leuchte-set for the actual lamp. As you probably already know, there are 8 x Lichtfunktion (i.e. A,B,C.. H) channels in each of the 35 x Leuchte-sets in the BCM


After many attempts using my test bench (my "virtual mk7") to fathom the complexity of how the fahrlicht bei tag adaptation channel works, I found that there is an interplay with this adaptation channel and the particular version of "daytime running lights" that is chosen in the Lichtfunktion setting

Here's a more detailed explanation that I made some time ago for the RT forum that describes the full matrix of options:



I guess that you could try the 2A-2B option in the picture with the LED headlights - but this is untested (for obvious reasons)

Don

[Whisp]

Very interesting, and yes, I can see what you mean about introducing aftermarket lights into the mix, and being relatively unsure of the outcome. The 2B option definitely was the one that did the trick for me. With the switch on Auto, in the daylight only the Double U DRLs are active. Then drove into an underground car park and the low beams come on as they should.

As these Supernova headlights are based on Aussie Golfs, I'm sure it allows them to match up wires as best as possible to work plug and play, and they basically do. What I also found interesting (but not surprising) is when you look at a picture of the new lights, the DRL is supposed to be on the Leuchte2SL & Leuchte3SL channels(?). However, because these are not OEM lights etc.. to actually adjust the brightness of the DRLs is under the Leuchte4TFL & Leuchte 5TFL -> Dimmwert EF 4. Which is obviously the same channel for setting the Halogen DRL brightness when they were installed.

I can see the interest in all of this coding and design, and if I was ever going to learn German, this is not a bad way to go about it.

[Jozh]

When in the off position, the DRLs are on, full brightness.
When in the Auto position, the low beams are on, regardless of time of day.
When in the Parkers(?) position, the DRLs are on, full brightness.
And dipped beams, normal low beam again.

Did you get it so that when your switch is set to off, the DLR are off? I dont know if my old halogens turned off when set to off as they were not bright to ever notice.

[Jap]

Got it working

Ok to get the footwell and door brightness sliders you need to change these 2 to from 0 to 8x1 (11111111, although I have tried any other 8 figure binary and it seems to work), IGNORE THE PATTERN OF 0-255 that Obdeleven puts up

Central electronics
Interior lighting, parameter:
p_ambientelicht_verbauinformation_HMI:
11111111 (default is 0, and this one is for footwell)
p_ambientelicht_verbauinformation_HMI_2:
11111111 (default is 0, and this one is for the door)

I’m sure HMI_3 & 4 will put the settings cog on for other lights like maybe Center console if you had them in your car
Now you will have the cogs on the brightness screen, but the glow will be WHITE

Now if you want the glow on the screen to be the same colour as your display (like my pictures are green down there vvv)

Interior lighting, parameter:
p_ambienteumfang_mehrfarbig_HMI:
100 (default is 0, footwell)
p_ambienteumfang_mehrfarbig_HMI_2:
100 (default is 0, door)

There you go independent footwell and door lighting with colour change

[Jap]

YouTube

done a video if it helps

[Azguard]

does the ambient light in the footwell change colour or are the factory leds not rgb? can you post a picture if they do.

[AT_SA]

The LED in the footwell/door are not RGB so you can't change the colour to correspond the console/head unit (confirmed by VW mechanic). I'm keen to know how/where to purchase the required RGB LED (or whether you need a whole new door card which won't be cheap) so that they can be interchangeable with the rest. Thanks for the codes they worked a treat and look good. My favourite is electric lime. I used the following website to come up with my own 10 colour schemes...

Yeah I was looking the other day

rror: Adaptive Front Lighting (AFS)

---

Good evening!
I have a 2013 GTI Golf, and I decided to change the AFS light because I had changed some lights and... then I decided to put a LED!But... there's a problem!
I've changed the AFS H7 to an LED! and the error appears because of the voltage indications, I think!

There is a way using Vagcom/VCDS to solve the error of AFS?

Some one to help?

Best regards

[DV52]

david: hi - can you post-up the actual error message? Even better, perhaps a copy of the autoscan results for the car so we can see how you coded the BCM.

Hi @DV52 this is the error message that the VCDS gives to me...


Thank you so much! Hope that some one can help me!
