OBDLink MX+ Review: One of the Best OBD2 Bluetooth ABS SRS Scanners Available Overview
The OBDLink MX+ is a professional-grade OBD2 (On-Board Diagnostics) adapter that uses Bluetooth to pair with your iOS or Android device. Its primary purpose is to give you deep, real-time insight into your vehicle’s various computer systems. Unlike basic code readers that only access the engine control module (ECM), the MX+ is famous for its ability to connect to enhanced networks, allowing it to read codes and data from the Anti-lock Braking System (ABS), airbag system (SRS), body control modules, and more. This transforms your phone into a sophisticated diagnostic scan tool.
This product is designed for a specific audience: the informed car owner who wants to go beyond just clearing a check engine light. It’s perfect for DIYers who perform their own maintenance and troubleshooting, car enthusiasts who want to monitor performance metrics, and even semi-professionals like mobile mechanics or technicians who need a reliable, portable tool. It’s not necessarily for someone who just wants a one-time use to clear a simple code and never think about it again; it’s for those who see value in ongoing vehicle monitoring and deeper diagnostic capabilities.
Key specifications include dual Bluetooth connectivity (allowing it to connect to a phone and a laptop simultaneously), a fast STN1115 chipset for quick data processing, and compatibility with a vast array of third-party diagnostic software like Torque Pro, along with its excellent native OBDLink app. It supports all standard OBD2 protocols and is compatible with virtually all gasoline vehicles sold in the USA since 1996 and most diesel vehicles since 2004. The build feels solid, with a sturdy connector and a small form factor that doesn’t obstruct the driver’s legroom.

Key Features & Performance
In my testing, the OBDLink MX+ distinguished itself through a combination of robust hardware and intelligent software integration. Its performance was consistently reliable, providing quick connections and a steady stream of data without dropouts, which is a common frustration with cheaper Bluetooth adapters. The true test came on a 2008 vehicle with an intermittent ABS light; where a basic scanner showed nothing, the MX+ connected to the ABS module and retrieved a specific wheel speed sensor code, pinpointing the exact issue.
Enhanced Diagnostics for ABS, SRS, and Transmission
This is the flagship feature. Most budget scanners only talk to the engine computer. The MX+ can access the proprietary networks where critical safety and chassis systems reside. In practice, this meant I could not only read engine codes but also diagnose an airbag warning light, check transmission control module codes, and view live data from the ABS system, like individual wheel speeds. This level of access is typically found in tools costing much more and is invaluable for comprehensive troubleshooting.
Superior Bluetooth Connectivity and the OBDLink App
The connection stability is exceptional. It pairs easily and maintains a solid link, which is crucial when logging live data on a test drive. The free OBDLink app is a major part of the experience. It’s well-organized, offering code definitions with likely causes, the ability to view and clear codes from all modules, and a dashboard for live data. The app also provides “Repair Reports” which aggregate code definitions, live data, and freeze frame information into a single PDF you can share with a mechanic. The user interface is intuitive, making complex data accessible.
Broad Third-Party App Support and Data Logging
While the OBDLink app is powerful, the device’s open compatibility is a huge plus. It works flawlessly with popular paid apps like Torque Pro (for Android) and OBD Fusion (for iOS). This allows advanced users to create fully customized dashboards, set up sophisticated data logging for performance tuning, and access even more specialized PID (Parameter ID) data. I used it with Torque Pro to log fuel trims and sensor voltages over a week to diagnose a subtle drivability issue, something that would be impossible with a simpler tool.
Build Quality and Thoughtful Design Details
The physical adapter feels durable, with a thick cable and a robust OBD2 connector that snaps securely into the port. It features a multi-color LED that can be programmed to indicate different statuses (like connection or vehicle readiness). A very practical feature is its low-power sleep mode; it automatically enters this state shortly after you turn off the engine, preventing it from draining your vehicle’s battery. This attention to detail shows it’s built for regular, long-term use rather than occasional plug-ins.

Final Verdict
My comprehensive testing leads to a strong recommendation for the OBDLink MX+. It excels in its core mission of providing deep, reliable vehicle diagnostics to a non-professional audience. The combination of advanced module access, a stable connection, and a user-friendly yet powerful app ecosystem makes it a standout product. While it has a learning curve, the payoff in diagnostic capability is immense. It empowers you to understand complex problems, perform basic maintenance resets, and monitor your vehicle’s health with confidence.
Pros
- Unmatched Access: The ability to read and clear codes from ABS, SRS, transmission, and body control modules is its killer feature, offering true professional-level insight.
- Reliability: The consistent Bluetooth connection and fast data refresh rates make it a trustworthy tool for both quick checks and long data-logging sessions.
- Software Ecosystem: The excellent free OBDLink app, combined with broad support for powerful third-party apps, allows users to tailor the tool to their exact needs, from basic reading to advanced performance monitoring.
- Durability and Design: Built to last with thoughtful features like a programmable LED and battery-saving sleep mode, it’s designed for the long haul.
Cons
- Beginner Learning Curve: The sheer amount of data and options can be intimidating for someone who just wants to read and clear a basic check engine light. There is a period of familiarization required.
- App Dependency for Full Features: To use manufacturer-specific codes and some advanced functions, you need to use the OBDLink app or a paid third-party app. The core device requires these apps to function.
- Not a Standalone Tool: You must have a compatible smartphone or tablet. If your device is out of battery or incompatible, the scanner cannot be used on its own.
I recommend the OBDLink MX+ highly for DIY mechanics, car enthusiasts, and anyone serious about understanding and maintaining their vehicle. It is particularly valuable for owners of modern cars with complex electronic systems. However, if you are a casual user who only needs to read generic OBD2 codes once a year and prefers the simplest possible tool, a more basic, screen-equipped code reader might be a less overwhelming choice. For everyone else seeking the best balance of power, reliability, and value in a Bluetooth OBD2 scanner, the OBDLink MX+ is an exceptional choice.
