Here are the instructions that [email protected] gave me a while ago.

It worked for me and 2 other people, chances are, it will work for you if you coded byte 18 by mistake.I had byte 18 coded to 04 by mistake. What you need to do if that's your case, is recode byte 18 again. Here is the procedure. Before doing anything make sure all your doors are unlocked and that they are closed properly.
-Go to byte 18 in central electronics 09 and recode it to 03.
-Do not it enter, click either on byte 17 or 19 and byte 18 will stay to 03.
-Afterwards, close your long coding screen and click do it! New long coding will be accepted.
-Close all you Vag-Com screens, turn the ignition off and unplug the cable from the obd port.
-Get out of the car, lock your doors and wait at least 2 mins so that the bcm falls asleep.
-After that, unlock all your doors, turn ignition on plug the cable back and re-open Vag-Com.
-Go back to your long coding in central electronics at byte 18. Recode it to 00. Close you screen hit do it! And long coding should be accepted.
-Again, close all your Vag-Com screens remove the cable, turn ignition off and test your lights. Everything should be working properly.
Let me know if you have more questions.
