WrenchLane now works in 26 languages, across the entire app. Not just the menus — the diagnostics, the possible causes, the repair data, and the in-app chat all show up in the language each person chooses. Pick yours once, and the whole workflow follows.

The New languages
The 9 new languages where shops told us the language barrier was slowing them down most:
- Dutch, Czech, Slovak, Romanian, Bulgarian, Estonian, Latvian, Lithuanian, Chinese
All languages
The 26 languages cover the markets all over the world:
- Nordics: Swedish, Danish, Norwegian, Finnish
- Western Europe: English, German, Dutch, French, Spanish, Italian, Portuguese
- Central & Eastern Europe: Polish, Czech, Slovak, Romanian, Bulgarian, Russian, Ukrainian
- Baltics: Estonian, Latvian, Lithuanian
- Beyond Europe: Turkish, Arabic, Persian, Hindi, Chinese
More will follow as we move into new markets — the system is built to add a language without re-translating everything else.
What WrenchLane is
For anyone new here: WrenchLane is AI-driven car diagnostics built for repair shops. A tech enters a vehicle and a fault — a VIN, a plate, a description, or a DTC like P0171 — and WrenchLane returns the likely causes ranked by probability, each with the reasoning behind it, plus the videos and technical service bulletins that help confirm and fix it. The goal is simple: cut the time between “the car is in the bay” and “we know what's wrong,” without sending a tech down three dead ends first.
That only works if the tech can read the answer without friction. Which is exactly why language matters more here than in most software.
Why 26 languages, and not just a menu translation
Plenty of tools offer a translated interface — the buttons change, but the content that actually helps you fix the car stays in English. We took the opposite approach. The parts a tech reads most — the cause descriptions, the “why this cause” explanations, the verification steps — are all localized. When a Mercedes GL throws a P0171 and WrenchLane suggests a vacuum leak in the intake system at 90% likelihood, that explanation reads naturally whether the tech works in Swedish, Polish, Turkish, or Arabic.
For a shop, that turns into a few concrete things:
- Mixed-language crews stay on the same page. Everyone sees the same diagnosis, each in their own language. No one is guessing at a translation mid-repair.
- New hires get productive faster. An apprentice or a recently arrived tech can start reading diagnostics on day one instead of waiting until their technical English catches up.
- Fewer misreads. A fault you understand fully is a fault you're less likely to act on wrongly — and that saves the comebacks that eat a shop's margin.

How to switch
It takes about five seconds. Open the menu in the top right, go to Profile → Language, and pick yours. The change applies across the whole app immediately, and it sticks to your account — so each person on the team can set their own without affecting anyone else's.
The bigger idea
A diagnostic tool earns its place by getting a tech to the right answer faster. Forcing that tech to work in a second language adds a step that has nothing to do with the car. Removing it is one of the most direct ways we can make WrenchLane faster to use — for the shop in Stockholm, the one in Warsaw, and the one in Istanbul alike.
If you haven't seen how WrenchLane handles a diagnosis end to end, this is a good moment to take a look. Book a demo and we'll run one in your language.
