What to know before ordering
Connection
Bluetooth, with common diagnostic apps.
Plug
OBD2 16-pin, 12V.
Compatibility
Gasoline cars from 2001, diesel from 2004.
What it reads
Engine and emissions — the most common warning lights.
What it doesn't always read
ABS, airbag, automatic transmission, and comfort modules, which often require a manufacturer tool.
What is in the box
  • The OBD2 Bluetooth device.
  • The manufacturer's instructions.
How to use it safely
  • Clearing a code isn't the same as fixing the problem: if the fault is real, the light will come back on. Understand it before you clear it.
  • Unplug the device when you're not using it: left connected permanently, it can draw a bit of power on some vehicles.
  • Don't operate it while driving.
Check before you buy
  • Locate your OBD2 port: it's almost always under the steering wheel, sometimes behind a cover.
  • Check your car's year: gasoline since 2001, diesel since 2004.
  • Plan to install a diagnostic app on your phone — the scanner alone won't display anything.

Description

What the check engine light does

It comes on, and it says nothing. At the garage, reading the codes is billed before any repair even starts — for information the car already stores. This scanner retrieves it.

How it works

The OBD2 port is mandatory on all gasoline cars since 2001 and diesel cars since 2004. It's almost always located under the steering wheel, within easy reach. Plug in the scanner, install a diagnostic app on your phone, pair via Bluetooth: the fault codes appear along with their meaning.

Clear it, sure — but

The scanner lets you turn off the light. That's useful when the fault was a one-off, or after a repair. It's not a solution: a real fault comes back, and the light turns on again. Clearing it without understanding is like unplugging a fire alarm.

What it does not do

It reads the engine and emissions systems, which covers most warning lights. ABS, airbag, automatic transmission, and comfort modules often require a manufacturer tool: don't expect a scanner under twenty euros to do what a professional diagnostic system does.

Worth knowing

  • Bluetooth, with common diagnostic apps.
  • Compatible with cars that have an OBD2 port, meaning gasoline since 2001 and diesel since 2004.
  • Free shipping within mainland France, with no minimum order.
  • 14 days to change your mind, returns accepted with no reason required.

When it earns its place

The check engine light comes on

It says nothing, and reading the codes is billed at the garage before any repair even starts. Yet the information is already in the car.

Before buying a used car

Five minutes plugged into a private seller's vehicle tells you if faults were recently cleared.

After a repair

You clear the code and check that it doesn't come back — that's how you know if the issue is truly fixed.

The MOT coming up

An emissions fault in memory will fail the inspection. Better to know beforehand.

Questions we are asked about this product

Is it compatible with my car?

If it has an OBD2 port, yes: it's mandatory on gasoline cars since 2001 and diesel cars since 2004. The port is almost always located under the steering wheel.

Do you need an app?

Yes, the scanner alone doesn't display anything: it transmits to your phone. An OBD2 diagnostic app is required, most have a free version that's enough to read and clear codes.

Can I turn off the check engine light?

Yes. But let's be clear: clearing a code isn't repairing. If the fault is real, it will come back. It's useful after a repair, or for a one-off glitch — not to make a problem disappear.

Does it read ABS and airbags?

Not reliably. It reads the engine and emissions systems, which covers most warning lights. ABS, airbag, and automatic transmission modules usually require a manufacturer tool — don't expect a device at this price to replace a professional scan tool.

Can it be left plugged in?

It's better to unplug it between uses: on some vehicles, a device left in place draws a bit of current.
