What Tesla shipped
Tesla has started rolling out Full Self-Driving (Supervised) v14.2.2.6, carried inside firmware version 2026.17.5, to European vehicles. The first cars to receive it are HW4 (AI4) Teslas in the Netherlands, the continent's most mature FSD market and the country whose RDW approval opened the door for the rest of Europe. Tesla announced the European push alongside its FSD approval in Denmark on 9 June 2026.
The official release notes list no new self-driving features. On paper this is a maintenance build, not a capability jump. What makes it significant for European owners is not what it adds but what it consolidates.
Why the branch merge matters
Until now, European FSD subscribers were running a software branch separate from the Spring 2026 Update that the rest of the European fleet received. That split meant EU drivers who paid for FSD could miss general app and vehicle improvements that landed on the main branch, and vice versa. Version 2026.17.5 closes that gap: it folds the European FSD branch and the Spring 2026 Update into a single install.
The practical effect is that European FSD subscribers now sit on the same software base as their counterparts in the United States, Canada, and other approved markets, rather than on an isolated regional fork. For Tesla, a unified branch is also far easier to maintain and update as more countries come online.
The driver-monitoring change
The most-discussed real-world difference is the driver-attention monitor. Owners running v14.2.2.6 report that the Driver Monitoring System is noticeably less strict in Europe than it was on the previous v14.2.2.5 build, with fewer nags during normal supervised driving. Tesla did not document this in the release notes, so treat it as an observed behaviour change rather than a confirmed specification. Drivers remain fully responsible for the car at all times — FSD (Supervised) still requires hands and attention.
Where Europe stands
The rollout lands during a fast-moving stretch for FSD approvals on the continent. The Netherlands, Lithuania, Estonia, Denmark, and Belgium have all granted approval in recent weeks, and Tesla has said it is aiming for a coordinated EU-wide rollout over summer 2026. For now the 2026.17.5 push appears limited to AI4 hardware; older HW3 cars are not part of this release.
If you own a HW4 Tesla in an approved European country, expect 2026.17.5 to arrive over the air in waves rather than all at once. Owners in countries still awaiting national approval will see the firmware but not the activated FSD functionality until their regulator signs off.
What to watch next
The branch merge sets up Europe for faster feature parity with North America. Once the unified base is widely deployed, the more capable v14.3.x line that North American cars are already running — including the latest parking and Summon improvements — becomes far easier for Tesla to bring across to approved EU markets.
