Did you know?

Small things recent updates changed, most of them missing from Tesla’s own notes.

Seat heaters have a timer now

Since 2026.32, they may switch off after about 20 minutes. Tesla did not mention it.

Trick or Treat unlocks more than you think

While it runs, Sentry Mode, the alarm and walk-away locking are off.

A phone inside is a key inside

A paired phone left in the car with Bluetooth on lets anyone open the door, even after locking in the app.

AMD does not mean HW4

Infotainment and driving computer are separate. Many features need a specific pair.

Your wheel choice changes your range

Wheel Selection feeds the range estimate: no aero covers, more drag.

.100 usually means Europe, until it does not

European FSD builds carried .100 in 2026; then 2026.39.6 broke the pattern.

How we check

Documented

Settings, menu paths and behaviour come from Tesla’s manuals and support pages.

Reported

Builds, dates and regions come from public trackers and are labelled. No rollout percentages: samples go stale in days.

Unknown stays unknown

If no source says a feature reached your country, we show a question mark instead of guessing.

Questions

What is the latest Tesla software update?

The newest widely installed branch is 2026.38. The cited tracker sample includes 2026.38.3.2 installs in Germany, and 2026.38.6, a fix build, has been rolling out since 29 October 2026, including in Germany. 2026.39.6 was also listed that day. Your car’s own Software screen is the only reliable answer for your car.

Is FSD v14 available in Germany?

The cited tracker sample does not establish German availability as of 30 October 2026. FSD v14.3 builds had been seen in North America, Ukraine, Australia and New Zealand. A 2026.39.6 build with FSD v14.2.2.6 was listed on 29 October without countries yet.
