Two things are making life easy for the RS4 seat-theft criminals and hard for the police. The first is the lack of identification on the seats linking them to the original car. Go on to eBay and RS4 seats can be sold with impunity. Audi confirmed to us that they still don't put VIN numbers on or tag the latest RS4 seats, something that energy trader McKenzie is unimpressed with. "It's not going to stop unless they help existing owners," he says, pointing out that identification data tagging on (Audi-owned) Ducati motorcycles has been standard since the late Nineties.
