Best OBD2 scanners

Top pick: BlueDriver Pro — a Bluetooth dongle that turns your phone into the scanner. It reads and clears engine codes, pulls manufacturer-specific codes and live data, and lives in the glovebox, so it suits most home mechanics best.

Who the others suit:

• Autel AL319 — the simplest, cheapest way to read and clear a check-engine light; no phone needed.
• Foxwell NT301 — a standalone screen reader with live data and readiness checks; good if you'd rather not use an app.
• Autel MaxiCheck MX900 — all-system diagnostics, bi-directional tests and an Android tablet; for serious DIYers and small shops.
• Topdon ArtiDiag900 Lite — similar tablet class, big battery, well rated; a strong alternative to the MX900.
• Innova 5610 — bi-directional tablet for deeper troubleshooting; check its reviews before committing.

Budget readers like the MOTOPOWER and Hyper Tough HT500 cover basic codes only.
