Why can an app give you the advantage?

Nowadays, most vehicles have electronic systems that record every fault. This data isn't exclusive to the mechanic: you can access it with an app and a small adapter.

This means that Analyzing your car is no longer something reserved for professionals. Now you can know:

• What faults does your car really have?
• If the check engine light indicates something serious
• How is the consumption, battery and temperature?
• If a problem can be solved without replacing expensive parts

What do you need to do it?

Very little. Just two things:

• An OBD2 adapter (plugs into the car's port and costs very little)
• A diagnostic app, such as Car Scanner, which works on Android and iPhone

With this, your phone becomes a tool capable of reading codes, interpreting data, and giving you clear alerts about your vehicle's status.

Benefits of analyzing your car yourself

• Savings on diagnostics: You avoid paying for basic check-ups at the workshop.

All this from your pocket, without technical knowledge and in a matter of seconds.

How does a diagnostic app work?

These apps read the data your car generates internally. When there's a fault, the system logs it with a OBD2 codePreviously, only the workshop could read them with expensive tools. Now, with the adapter and the app, you have direct access.

What can you do with the app?

• Scan for errors and see them explained in clear language
• Knowing whether a failure affects safety or not
• View real-time information (RPM, temperature, battery charge, consumption)
• Erase codes after minor repairs
• Prepare before the MOT (Technical Vehicle Inspection)

Scenarios where the app saves you

1. The check engine light comes on.
At the repair shop, they might tell you the problem is serious. You scan it with the app and see it's just a loose sensor. The result: you save time and money.

2. You are about to travel.
You analyze your car before leaving and detect a minor fault that you can correct, avoiding a breakdown on the road.

3. You buy a used car.
The seller says it's perfect. You connect the app and discover old errors erased. So you know what you're really buying.

Mini-guide: how to start analyzing your car

1. Buy an OBD2 Bluetooth adapter (easy to get online).
2. Download Car Scanner from Google Play or App Store.
3. Connect the adapter to the car's OBD2 port (usually under the steering wheel).
4. Pair the app with the adapter via Bluetooth.
5. Take the scan and receive the report in seconds.

You don't need any mechanical knowledge. The app translates the codes and explains the problem in simple terms. Some even suggest solutions.

Precautions and limits you should know

• These apps are not a substitute for a full professional check-up.
• If the problem is serious, you need a mechanic.
• Not all older cars are OBD2 compliant.
• Use a reliable adapter to avoid connection errors.

Still, for most users, it's a sufficient tool to keep track of the car's condition.

Why don't workshops want you to know this?

Because it reduces their advantage. Before, they had all the information and you had none. Today, the situation has changed. It doesn't mean you don't need a mechanic, but it does mean you can speak with authority and avoid overpaying.
