Xteq X-Setup Easter Egg
"To see the Xteq X-Setup 4.0/5.0 Easter Egg press F3 to bring up an undocumented menu. The OK button doesn't work, so just click the X in the upper right corner to close it.

Note: The F3 menu has been removed from newer versions of X-Setup, starting with 5.5 and above.

1. Go "Help -> About..."
2. In the right lower corner there is a blue window with Greetings and Credits, double-click in the field from the left of the picture (it's where "The newest information... " is written.
3. In the blue window you'll see the running line BMW 328i.
Pretty useless egg, but anyway...

Zoom Zoom Car
Go to "help and choose "about". Notice, off to the side, the bar that says the logo and "Do more faster". If you click this once, it obviously transports you to the Xteq home page, but double clicking it will cause a little animated Text car to zoom across in the animated "thank you" box. The graphics aren't all that great, but its pretty entertaining
