“I was this close to dropping $300 on a chunky scan tool. Then I found engine.codes.”
We turn any phone and a $10 Bluetooth dongle into a real scan tool, letting you read diagnostic trouble codes for free, forever. You can decide later if pricier gear is worth it.
How it works
- Plug the BLE OBD‑II dongle into your car
- Tap Connect and give Bluetooth permission
- Read engine codes in plain English
Engine.codes uses the Web Bluetooth API. It works on most Android and iOS devices and computers.
On iOS, use Bluefy – Web BLE Browser to use this site.
Buying guide
- Look for “ELM327 BLE” adapters
- Cost: about $10 online
- Avoid Wi‑Fi and Bluetooth Classic models; BLE gives instant phone pairing.
