Finding the “best” car diagnostic tool often clashes with the desire for “low cost,” especially when you’re looking for the convenience of a Bluetooth OBD2 scanner. For those on a budget, navigating the world of OBD2 readers can be tricky, particularly if you’re an iPhone user. Let’s explore what you can realistically expect from cheap OBD2 Bluetooth scanners and how to make the best choice for your needs without breaking the bank.
For basic car code scanning, ELM327-based OBD2 readers or their knock-offs are generally sufficient and represent the most affordable entry point. These scanners, while cheap, typically don’t include any diagnostic software. However, for Android users, apps like Torque Pro can be paired with these readers to provide functionality. iPhone users should be aware that Bluetooth ELM327 scanners often face compatibility issues. If you’re in the Apple ecosystem, you might need to consider WiFi versions of ELM327 readers for connectivity.

While these budget-friendly scanners are capable of reading and clearing error codes – which can be helpful for resetting maintenance lights like TPMS or oil change indicators – their capabilities are limited. They primarily function as readers and won’t offer advanced features such as in-depth repair recommendations or the ability to change car parameters.
If you’re seeking more advanced features, brands like BlueDriver and OBDLink offer superior performance. BlueDriver, for instance, is known for its user-friendly app and its ability to provide specific repair reports, suggesting likely faulty parts based on the error code and your vehicle model. While the BlueDriver app can be used independently to access repair reports by manually inputting vehicle details and error codes, the BlueDriver scanner itself enhances the experience with seamless data retrieval.

OBDLink MX+ stands out for its rapid data polling and enhanced diagnostics, including access to manufacturer-specific error codes. Although OBDLink’s user interface for accessing enhanced features may resemble a shopping cart, these advanced diagnostic capabilities are now available for free, offering significant value. Both BlueDriver and OBDLink MX+ surpass the typical budget for “cheap” scanners, generally falling around the $100 mark. However, this investment brings ongoing support for new vehicle models, detailed error code information, and model-specific fixes, potentially saving you money in the long run by guiding you towards accurate repairs.

Keep in mind that the OBD2 scanner market is constantly evolving, and older reviews may contain outdated information, particularly regarding subscription models or feature availability. When considering a cheap OBD2 Bluetooth scanner, focus on its core function: reading and clearing codes. For more comprehensive diagnostics and repair guidance, be prepared to invest in a higher-end tool like BlueDriver or OBDLink. For basic needs and getting started with car diagnostics, a cheap ELM327 scanner can be a practical and affordable entry point, just be mindful of potential iPhone compatibility issues and software limitations.
