Deze info ben ik ook eens tegengekomen op de site van VWvortex en lijkt op de instructie je op een Engelse site hebt gevonden. Het betreft wel een ander probleem. Here are the instructions that Dana@Ross-Tech gave me a while ago. 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. To clear up any confusion on terminology, BCM = Body Control Module. This module is also known as J519 -or- Address 09 - Central Electronics.
