hello to all,

anybody can help me in the information concerning the required VCDS coding?
on Touareg 2012 I replaced the halogen headlights with LED bi-xenon ones. LED is working, bi-xenon is working, but I have some errors when making diagnostics by VCDS. I tried to change coding for the first byte, but xenon light is flashing or high-beam is not working.
And the main problem that my VCDS program ( the version 11th) does interpret all bits inside the first byte...
Anybody knows how to undersatnd the bits here?
how to correctly make coding for LED bi-xenon on T3?

thanks

You must be very carefully with changing those bits and bytes. You say that your xenons are flashing. Thats not good. You can easily damage your xenons and xenon electronics.
When you tell the electronics that your car does not have xenons, the car will PWM the headlights and xenons doesn't like that at all. Xenons must have a constant 12V to work properly.

Actually I can make them not flashing by putting another value to 1st byte. but the main problem, that I can not see which bit is this byte is responsible for...
