LED Tail-lights Coding & Error Clearing
Thanks to ZIPN VW at

WARNING: I will not be held liable if anything occurs when attempting to change anything in the VCDS software. These instructions are created to the best of my knowledge and are as accurate as I can make them. Please be careful before you save your settings and always run Auto-Scan before any changes are attempted.

Load up VCDS, click on the Select button under Select Control Module

Click on the 09-Cent. Elect. button

Click on the Coding - 07 button

Click on the Long Code Helper button

You will have to find out where byte 18 is as indicated by the arrows in the above image on the 1) line (with the yellow texts). Place your cursor on that area and change the two (2) digits to the respective and known codes listed below (please be careful!):

Xenons Headlights without Rear Fog
1F, 20, 55

Cars with LED DRLs - 21

Xenons Headlights with Rear Fog

Cars with LED DRLs - 04 (Golf R, 2012 GTIs, etc)

Halogen Headlights without Rear Fogs

Halogen Headlights with Rear Fogs
22, 15

WARNING: SAVE your auto-scan before doing this. If you change any digits incorrectly, a whole bunch of errors/issues/etc. will occur. I will not be liable for you incorrectly coding your tail lights.

NOTE: Side-effects of coding may include hatch tails staying lit when open, side markers at low brightness, city lights as high brightness, etc. If this occurs, try another code. If none of the codes work for you in the list, please research or ask for help in the forums.

Press exit on the top left of the window.

This window will show up again. Press the Do It! button to save your work.

WARNING: Please review all your coding before saving your work.

Back to this window, press the Faults Code- 02 to start the process of clearing the bulb-out error on your dash.

This window will pop up and show you numerous errors regarding your tail-lights. Press the Clear Codes - 05 button.

Press the Yes button to clear the codes.

Once this is complete, the bulb-out error on your dash should disappear and no faults should be visible in the faults window. If there are any faults left, try another code and repeat these steps.
