Bluetooth OBD2 ELM327 Adapter – Car Diagnostics from Your Phone

The engine light comes on and you don't know whether it's trivial or serious.

A mini adapter that plugs into the OBD2 port under the steering wheel and shows fault codes on your phone via Bluetooth. You know what's happening before you go to the garage.

Why it works

• Reads fault codes.
• Clears them after a repair.
• Bluetooth 4.0 – no cables to the phone.
• Mini size – can stay in the car.

What you miss out on without it

• You pay the garage for diagnostics for every warning light.
• You don't know whether it's safe to carry on driving.
• You can't check a used car before buying it.

Where it comes in handy

Your own car, before buying a used car, on the road, a small workshop.
