Hi,

 

I'm planning to add some functions in my car using VCDS, as I'm quite fresh in using this tool, so  I decided to start from theoreticly simple things to train a bit. I decided to turn on fog lights as cornering light and...  

...I hit the wall .... I've tried verified coding (in fact adaptation) found on different forums including briskoda:

 

I'm using VCDS version 20.4.1

 

Here are controler details (in this version of controler there is no coding, but all was moved to adaptation as far I know)

after choosing 09-Central Electronics and entering security code 31347:

 

Leuchte12NL LB45-light B12 : not active -> Abbiegelicht links
Leuchte13NL RB5- light B13 not active -> Abbiegelicht rechts

then I checked if conditions for cornering lights are correctly set in other corelated adaptation channels:

IDE03638-IDE04231-static AFS light-Steering wheel angle: offset,-0.3 °,
IDE03638-ENG116677-static AFS light-Abdimmgeschwindigkeit,25.0 %/s,

IDE03638-ENG116674-static AFS light-Vorschrift,ECE R119 ,
IDE03638-ENG115830-static AFS light-Zeitwert Einschaltzeit Abbiegelicht,15 min,

 

Unfortunetly it seems to be not succesful with FL version. What is really strange it that I have checked with VCDS advanced measurments how controler is reacting on steering wheel turns and it seems everything works correctly (my version in Polish, so most of you have to belive me, but underlined line is showing Puls Duty Factor for left fog light):

 

 

 

After turning wheel, AFS signal become active, duty factor is 100% and plug number is exactly the same as for fog light. But all this is not reflected in real light behavior. 

 

I've tried reseting lights options in car setting to factory defaults, also I was waiting 30 min allowing CAN to go into sleep mode... no changes. 

 

Can anyone help me with those adaptations in FL version, it seems something has changed in FL and probably some additional adaptations / coding has to be done, maybe in CAN Gateway ?

Thanks in advance for any help.

 

 

At a guess, the fog light channels have changed so the below aren't actually the fog lights:

Leuchte12NL LB45-light B12 : not active -> Abbiegelicht links
Leuchte13NL RB5- light B13 not active -> Abbiegelicht rechts

 

Post an adaption map from 09 and I'll see if I see anything obvious

Yes, originally both were set to not active. Some lines in Polish, I hope you will be able to identitfy .  

adpmap-09-5Q0-937-086-CE_VIN-2100.CSV

Try changing these:

Leuchte16BLK SLB35BLK SL KC9-Lichtfunktion B 16 --> Abbiegelicht links
Leuchte17TFL R BLK SRB3TFL R BLK SR KC3-Lichtfunktion B 17 --> Abbiegelicht rechts

Keep the existing changes you've already made.

 

I'm pretty new to the MQB platform but I'm pretty sure that'll do what you want. I assume you have LED front fog lights?

Awsome . Thanks a lot langers2k, that's it ! It seems all aviable adaptations are for halogens, when FL models are with LED, but I'm wondering why they left 12NL and 13NL A function set as fog light while FL cars are delivered only with LED ones... Probably no one exept guys from Wolfsburg can answer...

@Phils80 May be as for Windows, they don't remove unused code lines on the new SW version. It's cheaper for development costs.  

It's more likely that the led module takes two power feeds. On previous generations, the led module took power and a PWM signal for brightness, both of which would turn off completely when it wasn't in use.

 

I haven't looked in to the lighting channels or writing diagrams to confirm 🙂

Hello guys,

 

I have an Skoda Superb 2020 FL and I've been trying for a while to activate cornering fog light. I have tried to change Leuchte12NL, 13NL; Leuchte2SL, 3SL, 4TFL, 5TFL but without success.

I saw here that @Philps was able to active cornering on fog lights. I will attached few foto with the code that I've changed(I will say the same as @Philps), but didn't work.

 

Could you please take a look on my photo and guide me?

 

Thanks in advance

You need to find which channels are fog lights.

 

Take a look through all the channels for something with functions "Nebellicht links" and "Nebellicht rechts" and change those

 

If you're able to get a full list of adaption channels and settings out of obdeleven, I can take a look.

Hi doggy007, thanks to langers2k I realized where was a problem. In FL cars you have LED fog lights which are not driven through same channels as before (when there were halogen fog lights). It was confusing because those channels are still present in adaptation, regardless that halogen lights are not possible to install anymore.  Please try to change those channels instead Leuchte12NL, 13NL; Leuchte2SL, 3SL, 4TFL, 5TFL:

 

Leuchte16BLK SLB35BLK SL KC9-Lichtfunktion B 16 --> Abbiegelicht links
Leuchte17TFL R BLK SRB3TFL R BLK SR KC3-Lichtfunktion B 17 --> Abbiegelicht rechts

I can tell you that cornering lights with led fog lights are helping a lot, so it is worthy to turn them on. It is good idea especially in cars without AFL as mine.

 

@langers2k as you see in the screenshot attached "Nebellicht links" and "Nebellicht rechts"  were available on Leuchte16BLK and Leuchte17TFL(I didn't change those, were present before coding).  As you say, modifying Leuchte16BLK and Leuchte17TFL, cornering on fog light should be working? I saw that you said above "Keep the existing changes you've already made." it is necessary to code and Leuchte12NL and 13NL?

I searched in all the channels and "Nebellicht links/rechts" are available on 4 channels :Leuchte12NL /13NL and Leuchte16BLK /Leuchte17TFL. I will try to code all these 4 channels together to see if it works.

 

@Philps I don't understand what you mean instead, in the above screenshots I already changed  Leuchte16BLK and Leuchte17TFL channels and the cornering on fog light didn't work.

 

 

after I tried to code all channels that contain "Nebellicht rechts/links", the cornering is working. Thanks guys for help.

I have often wondered why when most of the VCDS interface is in the users chosen language, e.g. Enlish in my case, some of the adaption channels are still in German. Could they not be translated by the software?

Im guessing here, as I’m no VCDS expert (but I get by) but it may be that there is no direct translation and that’s why it remains in German. There has been a number of times I have typed a phrase into Google Translate from OBDeleven and the English translation doesn’t really make sense. It is enough to work out what’s what though. 
 

Like I said. That’s purely my guess. It’s not based on any actual fact.

now it seems to be even more strange. In my case I've left Leuchte 12 NL and Leuchte 13 NL as fog lights because I was to lazy to rewert them to original setting.... Strange, but good that it works !

I find it strange too, but if it works it's OK. When you have time you can revert those channels only to see if cornering will work after .

Hello

IDE03638-ENG116681-static AFS light-Oberer Lenkradwinkel,65 °,
IDE03638-ENG116678-static AFS light-Unterer Lenkradwinkel,40 °,

what do these values mean?

I wanted to change sensitivity of cornering lights, so they light up earlier on more gentle turns, but couldn't really notice any difference while playing with these values, it's still engaged after about 90* turn of steering wheel.

I don't think what you want to do is a VCDS parameter and the ones you have modified translate as upper and lower steering wheel angle, you may have mucked around with the steering angle sensor, I suggest you revert them to the original settings.

I do not understand your use of the word "earlier", without it I understand what you wish to achieve (but I don't think it is a parameter), with the word it makes no sense.

Sounds like he wants them to come on without having to turn the wheel so much.

travs is right :) Factory setup is pretty much useless now on a bit winding roads, where corner lights could be handy but you don't turn the steering wheel more than, say, 45 degress.

I understand that, it was the "earlier" that confused me.

I dont think I have to turn the wheel 45°, mine lights up when I drive under my carport which is a very gentle slalom, different vehicle though.

Earlier in a process as opposed to earlier in actual time.

Agree that I don’t think mine is a particularly drastic angle for my needs but it could be something that OP does regularly that could do with some light and doesn’t have it. Horses for courses and all that.

I have to turn 90 or close to it, definitely far more than 45 :(

I also got different vehicle (Golf 7.5 with Top LED, corners are through additional light bulb in headlight, not anti-fog one), but I thought it might be similar for all MQB vehicles as my factory parameters are almost the same as Phil80's, I think IDE03638-ENG116677-static AFS light-Abdimmgeschwindigkeit,25.0 %/s, is different (I have 50% by default)

So... anybody? Any chance to lower the wheel angle needed for cornering lights?
