For any car owner who likes to get their hands dirty and tackle car maintenance at home, an OBD scanner is no longer a luxury—it’s a necessity. Modern vehicles are complex machines, and when that engine light pops up, you need a quick and effective way to understand what’s going on. That’s where the Best Cheapest Car Scanner comes into play, offering a fast route to diagnosing problems without breaking the bank.
Are OBD scanners actually worth the investment? Absolutely. Think about the alternative: a trip to the local garage just to identify a fault code. With labor costs easily hitting £50 per hour at independent shops, those quick diagnostic checks can become surprisingly expensive. Investing in even the best cheapest car scanner can pay for itself in a single use. Imagine pairing one of these affordable scanners with resources like Haynes AutoFix – suddenly, you have the power to diagnose and fix a wide range of common car issues and electrical problems right in your own driveway, using just basic tools.
The market is flooded with OBD readers, from basic models to professional-grade equipment. While the high-end scanners offer advanced features, the fundamental job remains the same across the board: communicating with your car’s computer to pinpoint fault codes. The good news is, you don’t need to spend a fortune to get started. Many scanners are available for less than the cost of a single garage diagnostic fee. But with so many options, how do you choose the best cheapest car scanner for your needs? Let’s delve into what makes these devices so essential.
What Exactly Does an OBD Reader Do?
An OBD reader, in its simplest form, is a handheld diagnostic tool that connects to your car’s onboard computer system. Its primary function is to read and interpret fault codes, which are essentially error messages generated by your car’s engine and other systems when something isn’t working correctly. While you can find very basic OBD scanners at incredibly low prices, and professional versions costing hundreds, every scanner should, at a minimum, be able to:
- Establish communication with your vehicle’s computer system
- Read and display diagnostic fault codes
- Clear or erase fault codes after repairs are made
It’s important to note that most basic and even some mid-range OBD scanners typically won’t handle tasks like turning off service lights for oil changes or resetting monitors for systems like ABS and SRS. For those functions, resources like Haynes AutoFix become invaluable, guiding you through these processes step-by-step.

Understanding OBD and How It Works
OBD stands for On-Board Diagnostics. The OBD system is accessed through a port in your car, often located under the dashboard, which resembles an old-style SCART connector. This standardized port has been mandatory in all petrol passenger cars sold in Europe since January 1, 2001, and in diesel cars since 2004. This 16-pin connector is known as OBD2 in most parts of the world and EOBD (European On-Board Diagnostics) in Europe.
The OBD port not only provides a communication link but also supplies power to the scanner. This means your best cheapest car scanner doesn’t need its own power source like batteries or a separate power cable – it draws power directly from your car, making it incredibly convenient and portable.
Choosing the best cheapest car scanner doesn’t mean sacrificing essential functionality. It’s about finding a tool that meets your needs for basic diagnostics at an affordable price, empowering you to understand and address common car problems yourself, saving time and money in the process.
