My latest TT-RS mod is all vain: E-code (aka amber reflector-less) adaptive cornering headlights.
After ordering them from BKS-Tuning and waiting about 5 weeks for them to arrive from Germany by boat, I eagerly installed them over the weekend. I was impressed to find out that the new lights included xenon bulbs, ballasts, and turn signal lights (and so they were 100% plug-and-play mechanically and electrically).
The mechanical part of the install is as easy as loosening a few screws around either headlight (I'll let a dealer do the final optical alignment). Coding / calibrating the E-code lights for my US-spec car was a little less obvious. Here are the steps I used:
1) Re-code the lights: go in through the 55-Xenon group in VCDS and first do a Security Access with 02000 and then change the Coding from 0000255 to 0000025. This sets the lights to match an "Audi 8J TT w/ magnetic ride suspension".
2) Go through a fake alignment sequence to get the dash MIL due to "headlights not aligned" to go away.
And now for the pics!

And a little side-by-side with another Suzuka TT-RS owner:
So now the question is, what are my OEM lights worth? Can someone with a TT that doesn't have LED DRL or adaptive cornering lights upgrade to my OEM lights? TBD...
