I did this retrofit last year on a 2011 GTI and recorded some crucial pieces of information. I had a highline CECM and OEM non-LED Xenons. I did not have to add any additional wires.
"Anyone that is coding LED headlights for a 2010 or 2011 I think the key is changing byte 18 to 20. And then enabling LED DRLs (Bit 2) on byte 27."
I hope this helps you!
