Frequently asked questions
My adapter isn't being detected — what do I do?
- Make sure the adapter is plugged in and the ignition is on.
- For Bluetooth: pair through OBD Pilot's "Connect to your car" flow, not iOS Settings. ELM327 adapters don't appear in iOS's general Bluetooth list.
- For WiFi: join the adapter's network in iOS Settings → Wi-Fi first (often "WiFi_OBDII"), then open OBD Pilot.
- iOS will probably say the adapter network has "no internet" — that's normal for OBD2 adapters and doesn't break anything.
Which OBD2 adapters work with OBD Pilot?
ELM327-based adapters made for cars manufactured after 1996. Both Bluetooth and WiFi variants are supported. Generic adapters sold under names like "OBDII", "Veepeak", "Vgate iCar", and "WiFi_OBDII" have all been tested.
Is OBD Pilot a replacement for a mechanic?
No. OBD Pilot is informational only. Always confirm any finding with a qualified mechanic before making a repair decision.
What's the difference between Pro and the free tier?
- Pro is a subscription (monthly or annual). Unlimited AI chat, unlimited diagnoses, full reports (verdict + causes + recommended actions), AI-enhanced PDFs, and photo / dashboard diagnosis.
- Free tier gets 3 AI diagnoses per device per month and a redacted version of the report (verdict + summary; causes and recommended actions are blanked out). Quotas reset monthly. You don't need to sign in to use the free tier — we use Apple's DeviceCheck to count requests, not an account.
How do I cancel my subscription?
iOS Settings → [Your Name] → Subscriptions → OBD Pilot → Cancel Subscription. Cancellation takes effect at the end of the current billing period.
Why does the AI sometimes give wrong-sounding advice?
AI models can occasionally make mistakes, especially with vehicle-specific details. The trouble codes themselves are accurate (they come straight from your car's ECU); the AI's interpretation is best-effort. Confirm with a mechanic before any repair.
Does OBD Pilot work without an internet connection?
- Demo mode and basic scan + DTC database lookups work offline.
- The AI chat and AI analysis features need internet.
My subscription isn't showing as active — what now?
In Settings, tap "Restore Purchases" inside the paywall sheet. If it still doesn't appear, email hello@obdpilot.com with your Apple ID purchase email and the date you subscribed.
Where is my data stored?
On your device only — diagnostic scan history, chat sessions, app preferences, and your Garage of saved vehicles. AI chat and analysis requests are sent through our proxy at scanai-proxy.vercel.app to OpenAI for processing. Our proxy is stateless — it doesn't log request bodies. OpenAI retains API request data for up to 30 days for abuse monitoring, then deletes it (per their API policy).
How do I delete my data?
Delete the app from your iPhone — all local data is removed. You can also reset an individual chat conversation in the Chat tab (new chat), which signals our proxy to forget that session's context immediately.
