The best car diagnostic devices for professionals and DIY enthusiasts – guide from auto-diagnostik.de
If you want to take care of the maintenance of your vehicle yourself or run a workshop, vehicle diagnostic devices are indispensable. They allow you to read error codes, identify problems early and optimize maintenance. In this article, you will learn how vehicle diagnostic devices work, which are the best models and how to choose the right device for your needs.
What is a vehicle diagnostic device?
A car diagnostic tool is an electronic tool that connects to the vehicle via the OBD2 (on-board diagnostic) port. It reads error codes generated by the vehicle's on-board computer when there is a problem. These error codes provide valuable information about the condition of your car and help to quickly identify problems.
Types of Automotive Diagnostic Devices
There are two main types of diagnostic devices: OBD1 and OBD2. OBD1 was used before 1996 and was less standardized, while OBD2 is mandatory in all vehicles from 1996 onwards. OBD2 devices provide more detailed information and greater compatibility with modern vehicles.
How does an OBD2 diagnostic device work?
An OBD2 diagnostic tool is simply plugged into your car's OBD2 port, which is usually located under the dashboard. Once connected, it reads error codes from the vehicle's ECU (engine control unit). These codes tell you which systems in your car are affected, such as the engine, electronics or emissions control.
Advantages of automotive diagnostic devices for DIYers
For DIY enthusiasts, a diagnostic device is an investment that quickly pays off. You can diagnose simple problems yourself and in many cases fix them straight away without having to visit a workshop. This not only saves time, but also money, as you can identify errors early and prevent major damage.
Why automotive diagnostic devices are indispensable for workshops
Professional workshops cannot do without diagnostic devices. They enable errors to be identified more quickly, repairs to be carried out more efficiently and customer service to be improved. Modern diagnostic devices also offer functions that allow you to monitor live data from your vehicle and thus make a more accurate diagnosis.
The most important functions of a vehicle diagnostic device
A good vehicle diagnostic device should offer the following functions:
- Reading and deleting error codes : The most important function. It helps you quickly find out what is wrong with the vehicle.
- Live Data Monitoring : Shows you real-time engine data such as RPM, speed and temperature.
- Compatibility with different vehicle brands : Make sure that the diagnostic device is suitable for the vehicles you use.
How to choose the right car diagnostic device for your needs
Choosing the right diagnostic device depends on how you want to use it. If you are a DIY enthusiast, a simpler model with basic functions is often sufficient. Professional workshops should look for devices with comprehensive functions and a wide range of vehicles. Here at auto-diagnostik.de we offer a large selection of devices for every requirement.

How to interpret diagnostic error codes
Each error code consists of a combination of letters and numbers. The most common error codes begin with a "P", which stands for problems in the drive train (eg engine and transmission). An example is the error code P0420 , which indicates a problem with the catalytic converter.
Tips for the care and maintenance of your vehicle diagnostic device
To ensure that your diagnostic device works for a long time, you should maintain it regularly:
- Check for software updates to ensure your device remains compatible with the latest vehicle models.
- Store it safely and protect it from moisture and extreme temperatures.
- Avoid shocks or impacts that could damage the device.
Common error codes and their meaning
Here are some of the most common error codes and what they mean:
- P0300 : Misfire detected, often caused by faulty spark plugs or ignition coils.
- P0171 : Mixture too lean, which may indicate problems in the fuel system.
- P0420 : Catalyst efficiency below threshold, often an indication of a worn catalyst.
How automotive diagnostic devices have revolutionized vehicle maintenance
In recent years, automotive diagnostic devices have fundamentally changed the way we maintain our vehicles. In the past, it was often difficult to diagnose vehicle problems without expensive visits to the garage. Today, almost anyone with a simple diagnostic device can read error codes and maintain the car efficiently.
The Role of Diagnostic Devices in Electromobility
Electric and hybrid vehicles require special diagnostic devices to monitor the complex electrical systems. More and more diagnostic devices now offer functions for checking high-voltage systems and hybrid drives.
