Hi guys

Been reading up on the coding ( or adaptation channel in central Electronics) part for the Golf Mk7 since two days ago i changed my rear lights from the traditional Halogen Bulbs to LEDs.

Before i did that i read a bunch of threads in the forum of how to go about this the right way and how i need to go in to the "Leuche 16-19" and change their setting to the "LED blinkeleuchen" wich i did and the car accepted the coding in ODB11 but when i was going to test it all out i still got the fault codes come up on my dashboard "Check rear blinkers"... and ontop of that in my rightside tailgatelight just went dark and did no longer want to light up.
Can anyone explain to me what i did wrong?

Unfortionate for me i dont have the time to sit and experiment to much with it since i dont have a whole lot of free time on my hands.

Anyway i have saved the history of my changes in odb11 and i will post what i did here, its in Swedish but i think you guys will know whats what anyway thanks for helping me
Ps. I had to put back the old bulbs and code it back to stock again since im dooing a long drive today but i will get back to LEDS tonight...

golfwagwan : Hi.

First off, my understanding from reading lots of Leuchte-set maps on cars from different countries on this fragile blue planet is that vehicles from Scandinavia are factory programmed differently (I suspect because of your local road rules). I mean no offense in making this observation - the lighting requirements in your part of the world clearly suit your local conditions and that's OK with me!!

My other difficulty given the special nature of your cars is that because of Australia's placement, I don't get to see too many Scandinavian cars!

With these caveats as context- my reading of your History records is as follows:

In general, your approach seems to be correct - however, because after-market LED retrofit bulbs are non-OEM (by definition), they vary greatly in their ability to function correctly on MQB platform cars like your mk7. But - in principle, it is correct to try to use the LED operating function within the Leuchte facility whenever the bulb that's plugged into the lamp-base is LED. This said, I seen a not insignificant number of cases where it simply has not been possible to do this properly with some after-market LED retrofit bulbs - because of the manufacture type of these lamps!!

So- my first observation of the change records in your post is that some of the adaptation channels listed have a Lasttyp setting old value= not active (i.e. Gammalt värde= inte aktiv). These Leuchte-sets have been factory disabled - so, there is no point changing any settings in these Leuchte-sets because the pin on the module that is controlled by this function does not have a connected wire.

Again with the caveat above about the special nature of your country's cars - it seems that the correct Leuchte-sets for your rear blinkers is :

Leuchte19BLK HRC31
Leuchte18BLK HLA60

Notice the letters that I have highlighted - these define which car-side the Leuchte-set controls. So in German, "Links" (or Left) and "Rechts" (or. Right)'

I'm guessing what might be the problem with your particular non-OEM lamps- sometimes changing only the Lasttyp channel is not the full fix for this retrofit exercise. Maybe you also need to change the lamp illumination level (which is controlled by Pulse-Width-Modulation)

Try this (as well as the lasttyp change) for the 2 x Leuchte-sets above:

Dimmwert AB > 127 (default=100)

whataboutthis: le4dsoldier if you have a pre 2024 VAG motor that is supported and you have the Pro or Ultimate license you can code Adaptions and long Coding but after 2024 SFD2 STOPS YOU. SFD Can be unlocked but basic plan only allows you to use OCA Nov 21, 2024 16:52:53 GMT

whataboutthis: fliew you need to share more info, car year have you coded in obd11 or vcds etc there is no magic button to revert to factory setting you have to undo all your changes manually in Adaptions and Long Coding you can copy/paste if you have backup Nov 21, 2024 16:54:18 GMT
