As a car owner, understanding your vehicle’s health is crucial. Modern cars are complex machines, and when something goes wrong, the first sign is often the check engine light. This is where OBD2 scanners come in handy. These specialized gadgets for self-diagnosis of your car are available in two main types: standalone and adapters. Standalone scanners gather information about malfunctions and display it on a built-in screen. Adapter-type scanners, on the other hand, require a smartphone for setup and visualization of diagnostic results, connecting via Wi-Fi and a dedicated app.
One of the most critical factors when choosing a car diagnostic scanner is its compatibility with your specific car model. The market offers three main types of devices:
- Brand-specific: Compatible with a single car brand.
- Multi-brand (Universal): Suitable for several car brands.
- Model-specific: Designed for a particular car model.
To simplify the selection process for car owners, we’ve curated a list of the best OBD2 scanners for 2025, based on user reviews and the expert opinion of Sergey Dyachenko, owner of The Garage auto repair shop and auto parts store.
