I have a 2010 3 door 2.0l TDI s-line with standard halogens. I wish to replace these with single Xenon (not bi-xenon) headlights with the LED DRLs. Just talking headlights here, I already know about leveling and washers, are these a straight swap with a few settings changing in VCDS? I have found adaptors for installing bi-xenons but not single xenons. If anyone can help, that would be great!
