Does it work with iPhone and Android?

It uses Bluetooth and is meant to pair with both phones and Windows PCs. Check the app you plan to use lists this adapter before buying.

Can it clear the check-engine light?

Yes, it can read stored fault codes and clear them on OBD-II vehicles. Clearing a code does not fix the underlying problem.

Which vehicles does it support?

It is for OBD-II compatible cars and light trucks, generally model year 1996 and later in the US. Older or non-OBD vehicles will not work.

Do I need to buy an app?

The adapter needs a third-party app to display data. Some apps are free and some charge for advanced features.

Can it do advanced diagnostics like ABS or airbag codes?

Usually not. It covers standard engine and emissions OBD-II data; manufacturer-specific systems need a more capable tool.

Is it hard to set up?

Plug it into the OBD port, pair it over Bluetooth and open your app. Setup is quick, though pairing can take a few tries on some phones.

Our take on the Bluetooth MX+ OBD2 Scanner

A compact Bluetooth OBD-II adapter that plugs into the diagnostic port and turns a phone, tablet or Windows PC into a code reader. It reads and clears fault codes, shows live sensor data and works with a range of third-party apps. It suits drivers who want basic diagnostics without a dedicated handheld tool. Against brand-name adapters like the OBDLink MX+ or Veepeak, it is a generic unit, so app support and firmware quality are the main things to check before buying.
