Did you figure out what was causing the flicker?
Was it the DS1 bulb, the ballast, or some connection?
Great post. Should help be with a bulb replacement (amber driving bulb). In your post you mention you had "VAGed" the lights. What exactly does this mean. I would like to disable the forced daytime running lights function but haven't' sorted through my VAG com to understand how do do that just yet. I have an 04 V10 with xenon lights. It has nearly all of the bells and whistles available in 04 except locking rear and quad zone climate control.
Thanks again for the outstanding post and any assistance you might provide.
