I've noticed that the screen on my RNS-E will sometimes flicker for a millisecond. It wasn't an issue at all when I was running the EU software, since I would hardly ever notice it, but now that I have switched to the US software, it will return to the "Warning" screen anytime this happens. It isn't too often, so it isn't really a big deal, but it is annoying nonetheless. I've VAG'ed it, and there are no codes, however I remember reading 1 or 2 other posts on here from B5 owners with similar issues. Anyone have a fix for this? Thanks.
