ok, you convinced me not to buy it, as it will bother me after 3 days of use...I have one one of these Diskloks which I used when I got my previous AMG and was paranoid about it getting stolen. I found it a faff to use and stopped eventually. It didn’t help that mine was difficult to unlock sometimes, seemed the key wouldn’t go all the way in and turn so I was stuck with it locked on. Always managed to get it unlocked eventually but not a good feeling.
The dealership said there is the Audi fitted alarm and immobiliser, so I suppose it's good enough, no ? I have no idea what category it is and how it works, though...
