Tesla is hitting back at a growing gray market of unauthorized devices that unlock Full Self-Driving (FSD) in regions where the software hasn’t been approved. The automaker has been remotely disabling FSD on affected vehicles — permanently revoking access without warning. Reports are surfacing from owners in Europe, South Korea, China, and Turkey that Tesla remotely woke their vehicles, detected the unauthorized CAN bus devices, and stripped FSD entirely — reverting them to basic Autopilot. The €500 hack that bypasses Tesla’s geofencing The devices at the center of this crackdown are small, USB-like hardware modules that cost around €500 and plug directly into a Tesla’s Controller Area Network (CAN) bus. They bypass Tesla’s regional software locks and geofencing to activate FSD (Supervised) in countries where the feature hasn’t received regulatory approval. The concept gained significant attention after Michal Gapinski, the developer behind the Tesla Android project, demonstrated how a CAN bus device could be used to unlock Tesla’s software-locked features by piggybacking on the infotainment system. Since then, a cottage industry of similar devices has sprung up — particularly in Europe, where Tesla owners have been waiting years for FSD approval that keeps getting delayed. That frustration is understandable. As we reported last month, Tesla’s European FSD approval through the Dutch RDW has been pushed back repeatedly, with the latest expected date being April 10 — tomorrow. EU owners have been burned so many times by missed deadlines that many turned to these hack devices instead of waiting. Tesla’s enforcement: permanent bans, voided warranties Tesla’s connected vehicle architecture gives it full visibility into what’s running on its cars. The company has been monitoring vehicle logs for abnormal behavior, and when it detects an unauthorized CAN bus device, the response is severe. In China, owners who activated FSD through the hack
