No lines on my mk8 2011 tourer, and useless for close quarter parking, may be helpful when connecting a trailer as for the rest just a gimmick, and those "beepers" turned them off straight away.
My one "talks" to me "THE DOOR IS OPEN"" PLEASE FASTEN YOUR SEAT BELT", one thing it does not tell me is oi you the lights are still on" just a feeble beep for that one.
