Connect to real Tesla vehicles through the official diagnostic platform, decode any VIN, and track certificate expiry across your whole shop — from one dashboard built for independent Tesla service centers.
Why T-Diag
Built for independent Tesla technicians who need real diagnostic access — not a stripped-down simulation.
Connect straight to Tesla's official diagnostic platform for the vehicle in front of you — no separate login, no shared password to remember.
Model, year, drivetrain, and battery details from any VIN — plus open NHTSA recalls for that model and year.
Every VIN your shop has connected to, its certificate status, and who last worked on it — logged automatically.
Submit a restoration request with the customer and vehicle details — handled securely, encrypted at rest.
Every signup is verified over Telegram before it's ever activated, and access can be time-limited per employee.
Pick a plan, and we're notified instantly — most accounts are activated within minutes, not days.
Compatibility
Which cable you need depends on the model and year. Most current-generation vehicles just need a standard Ethernet cable.
Getting connected
Setup depends on your plan — an unlimited plan authenticates automatically, a per-VIN plan needs the diagnostic port unlocked first.
Any vehicle, anytime

FAQ
