Tiptronic question

[CodeCyan]

For those of you with tiptronic gearboxes, could someone please confirm whether it's necessary to press the gear lever button in order to enter Reverse (R) while in drive or neutral?

I haven't had my MY 2004 986 for long, but I'm certain when I first bought it, it was necessary to press the button in order to change into reverse - Now it's no longer necessary. Seems strange but nothing is stopping me from slamming the car into reverse while driving at 120kph. That surely can't be good for the gearbox or my nerves.

Thanks in advance
