Bluetooth OBD2 scan tools offer a convenient way to diagnose car problems. But with so many options available, choosing the best one for your needs can be challenging. This article explores various Bluetooth OBD2 scanners, highlighting their capabilities and limitations to help you make an informed decision. A simple $13 Bluetooth OBD2 dongle paired with a phone app may suffice for basic diagnostics. However, these setups primarily read OBDII system data. For more advanced functionalities, such as reading non-OBDII systems or accessing oil level information (not part of standard OBDII data), a more sophisticated tool is necessary.
Beyond Basic OBD2: Delving into Advanced Diagnostics
While entry-level Bluetooth OBD2 scanners provide basic diagnostic information, they often lack the capability to interact with a vehicle’s full computer suite. Tasks like resetting oil change lights or manipulating electric parking brakes require tools that can communicate with non-OBDII systems. For instance, the VeePeak line of scanners explicitly states its limitation to OBDII scanning. Accessing manufacturer-specific systems necessitates a tool capable of interacting with proprietary communication protocols, similar to how the VIDA/DiCE combination works with Volvo vehicles.
Affordable Single-Brand Solutions: The Autel DiagLink
For around $90-$100, the Autel DiagLink offers a cost-effective entry point into advanced diagnostics. However, it’s crucial to understand its single-brand limitation. Upon purchase, users select one free brand-specific software package to download and install. While this allows for in-depth diagnostics and functions like resetting oil change lights and controlling electric parking brakes for the chosen brand, accessing other car brands requires purchasing additional software packages (approximately $10 each). This makes the DiagLink an excellent choice for owners dedicated to a single car brand but less versatile for those working with multiple vehicles.
Multi-Brand Versatility: Exploring the Autel MD806
For broader compatibility, the Autel MD806, priced around $200, provides a more comprehensive solution. While potentially utilizing similar hardware to the DiagLink, the MD806 boasts software supporting multiple car brands without requiring separate downloads for each. It also includes “lifetime” free software updates, although this typically refers to the tool’s expected support lifespan rather than indefinite updates. With its ability to handle various car brands and advanced functionalities, the MD806 represents excellent value for home mechanics and enthusiasts who frequently diagnose and repair vehicles. It bridges the gap between basic code readers and professional-grade scan tools.
Conclusion: Selecting Your Ideal OBD2 Scan Tool
Choosing the best OBD2 scan tool depends on your specific needs and budget. For basic diagnostics, an inexpensive Bluetooth dongle and app might suffice. However, for comprehensive scanning, including non-OBDII systems, investing in a more advanced tool like the Autel DiagLink or MD806 is necessary. Consider factors like brand compatibility, required functionalities, and long-term value when making your decision. Remember to research specific models and read reviews to ensure the chosen tool aligns perfectly with your automotive diagnostic requirements.
