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

[DV52]

Yeah I looked at it all and changed all the window stuff back, but still nothing. Actually had to go re add the key fob otherwise the windows couldn't roll up at all. Do the door mounted window switches fall under the BCM or door modules? Do you know what the soft reset box is in the adaptation screen?

Ben, the door mounted switches are wired directly to the door control modules, but this doesn't mean much with the CAN network. The soft reset box is the same as turning the ignition key off/on.

Have you tried resetting to factory settings in the MENU and are you aware that the reset procedure for "fast-glass" is to hold down the window down button for a few seconds after the windows bottom-out, then to pull-up the window up button for a few seconds after the windows roll-up? You might need to do this a few times.

Hi Don,

Thank you for your excellent explanation, I now understand the coding options much more fully!

Your step by step instructions worked perfectly! Much appreciated.

Now I understand the commands better, I have also altered the 3rd brake-light blinking so that it blinks with the outer turn signal.

Thanks again for all your coding help and tutorials!

So most bizarre thing. Went back and reset all all adaptations and coding to stock from coding log for the BCM. Window switches still not working for up position. Went through and cleared out and put stock coding in 17 instrument module (only change made was adding fuel refill quantity, removed now), and both door modules for mirror sync and passenger reverse dip. Once I put those back to stock the switches all work as advertised! Hmmmmm, maybe this is something new for the 2017s. Either way, if anyone runs into this issue, might want to consider other modules and not the BCM. I'll eventually dive back into eliminating the exact culprit, but just happy it's working correctly now!

Rear fog light as #1 in three-step turn signal (?)

I saw the Kencha (sp?) mod where the inner/outer signal rear signal lights alternate - approximating (I think?) the three-step (inner-middle-outer) signal lights, for example, found on recent Mustangs (very cool).

So - I'm wondering if there's a way of coding the rear fog light position on each side (L and R) so that it's "step 1" of a three-step rear signal light.

The way I think you'd have to do it would be to have the rear fog come on and stay on as long as you're signalling, then have the middle come on, then that stays on while the outer also comes on, then the middle-outer go out simultaneously.

Thoughts? Ideas? Suggestions? Mockery?

There is only one fog light at the rear (in AUS anyway. Do NA models have them both sides?), and you'd annoy the cr%# out of the person behind you by blinding them.

That's the only mockery I can manage at this time in the morning

The other issue is there are only two phases to the indicator in the BCM that you can code against. Lit or unlit.

This means you can definitely code the fog light to come on when you indicate, and have the inner and outer lights alternate based on the two phases, but you won't be able to code them to extinguish at the same time between cycles. As this would require a third phase.

For example, to achieve what you have described, you would need to code this way:

Lit Phase: Fog on, inner light on, outer light off.

Unlit Phase: Fog on, inner light off, outer light on.

Third phase (doesn't exist): fog on, inner light off, outer light off.

Nuje: Hi - Allow me to add to agentthumb's excellent response, please.

At a fundamental level, the standard wiring for the two rear fog lights on a mk7 will be problematic to achieve your (interesting) lighting effect. The perhaps not surprising feature about Leuchte programming is that whilst it's possible to allocate up to 8 x different functions to an individual lamp, the instructions from a Leuchte-set are sent to a single pin on the BCM (what VW calls "J519", or the module @ address hex09 on the VCDS autoscan)

As I explain in my Leuchte programming paper, the naming protocol that VW uses for their Leuchte channels identifies which pin on the BCM that will be affected by the setting value. For example, for (4)-Leuchte26NSL LA72-Lichtfunktion A 26, which is one of the channels for the rear fog light(s) - the A72 means that this channel value is allocated to PIN #72 of Socket A on the BCM


So, here's the fundamental problem with your suggestion (and I don't intend any mockery) - the standard wiring arrangement for the rear fogs is as follows:



Notice that the two rear fog lights are wired in parallel, which means that they share the same PIN on the BCM - which means that there is only one Leuchte-set for both lamps - which means that it's not possible to turn on/off just one lamp at any instance (i.e to make just the left fog light blink - without also making the right side fog light blink)

Alas

Don

PS: Of course, if you were sufficiently motivated, you could re-wire one of the fogs to a spare "Leuchte PIN" on the BCM (there are a small number of unused Leuchte-sets in the BCM) , but then you would need to consider the matters in Agenttumb's response

Excellent and detailed technical response as always DV52. Good pick up on the fogs being wired in parallel. I take it that means NA models do have two rear fog lights. ADR getting in the way again I'm going to guess

Hallo.
I'm new on forum so please excuse me if I make some kind of mistakes writing my message.
I have a question. How to switch on the control light on instrument cluster for rear fog light?
I'm asking because: I bought 2015 GTI from US. I live in Europe and here I need to have rear fog light and amber turn signals.
My car was equiped in rear lights (NON LED) without amber turn signal and fog light bulbs.
I've allready changed tail lights on EUROPEAN type lights ( NON LED) and also lights switch. Using information from this post and from DV52 member my friend helped me to make coding with VCDS. Everything works exept when I turn on rear fog light there is no control light on instument cluster confirming that fact. Sorry for my English.

To answer agentthumb's question: NAR cars actually have ZERO rear fog lights; however, there is a "dummy" section inboard to the inner rear light housing on both sides. We also have a vacant socket on the bulb-holder assembly - so, it's just a matter of cutting out the little plastic piece covering up where our rear fog bulb would go, doing the wiring and coding and - boom: rear fog light.

The fact that there is only one circuit/wire/pin from the BCM that controls the rear fog, though, means that (as both you and DV52 have adroitly pointed out) my quest is a non-starter.

Thanks for the info (and minimal mockery )

Don't apologise about your English - it's very good and it's far better than my Polish!!

So, in respect of your question, I'm a bit confused about your description of events. If your "friend helped [you] to make coding with VCDS", then presumedly your friend selected Byte 7 then enabled Bit 4 “Light Switch with Rear Fog Light(s) installed” on the code string for the BCM - see below



If this changed was made, it should have enabled the rear-fog light symbol in the instrument panel when the rotart light switch is pulled out twice - as below



was this step done?

Hallo.
Thanks for fast reply on my issue.
I'm sure he did not changed that in code string.
My friend is on hollidays till end of the week.
We will change it as soon as he'll be back from hollidays.
One more question - is it possible to change it with obd11?
I'm asking because I've orderd obd11 pro to learn some more.
I read Your posts about beging with vcds and obd11 - and I decided to buy obd11 as beginer.
Thank You verry much for Your answer.
With regards Piotr.
P.S.
Verry good polish "Witamy na forum"

Piotr W: All (most?) programming changes that can be made to the control modules in VAG vehicles via VCDS can also be changed with OBD11 and this tweak is no exception - see below. Note the yellow English descriptors in my picture are NOT on the OBD11 screen - they are my additions!

[Piotr W]

Hallo again.
Thank You verry much for another acurate answer.
Again I'm impressed of Your knowlege.
Respect.
That means I can do it myself but I'm still waiting for OBD11.
Maybe it will arrive monday. I hope so.
I have another question if You don't mind.
How to change that my radio go's OFF when I turn the key in ignition to "0" position.
I want to change it so it goe's off when I take the key out from ignition ( it works like that in my other car - MK5 with RNS510) .
Is it possible to change the way it works at that moment. Or maybe my ignition isn't working properly? But my car has milege only 15k km.
With regards Piotr

hi all!
i´m trying to fix a little strange behaviour with rear lights included license plate light but not 3rd light, when switch off the engine the rear lights stays on until open the door. only happens in light switch AUTO. im checking with different codings comparing and nothing helps.
anyone think what happen?
