Here's an interesting one from the Audi Forums A3 Series: A3/S3/Sportback (8P Chassis)
And I quote: "He just had all four rotor wheels stolen off his A3 sportback. The little scumbags have smashed the back window, used the cars own tyre iron and jack in the boot and removed all the wheels. This apparently is a big problem at the moment so just be aware as best as you can."
I'm horrified at this, never gave it a thought.
However, one of our contributors (S*e_N**a) has posted that he/she IS aware and has already offered a 'remedy' that he's prepared to share via a PM: I respectfully suggest you/us RS3 owners look at this thread and PM the guy (he/she) for his/her advice; I already have and am waiting.
I'll be applying it (whatever it is) to both my TT and RS3.
