For car owners and DIY enthusiasts, having a reliable OBDII scan tool is essential for diagnosing vehicle issues. While cheap Bluetooth ELM 327 dongles paired with phone apps are available, they often fall short when it comes to accessing deeper diagnostic data beyond basic OBDII systems. These basic tools typically cannot read non-OBDII systems or provide information like oil level directly – although they might report OBDII codes related to a faulty oil level sensor. Brands like VeePeak clearly state their entry-level models are limited to OBDII scanning only. For more comprehensive diagnostics, including interfacing with non-OBDII systems, a more capable tool is necessary.
Stepping up from basic OBDII readers, the Autel DiagLink emerges as a strong contender for the best OBDII scan tool under $100. This tool distinguishes itself by offering access to advanced, non-OBDII functions, typically found in more expensive devices. The key consideration with the DiagLink is its brand-specific nature. Upon purchase, you choose one vehicle brand for which you receive free, in-depth diagnostic software. This software, downloadable from Autel, unlocks the tool’s ability to perform tasks like resetting oil change lights and placing electric parking brakes into service position – functionalities often unavailable in generic OBDII scanners within this price range.
While the DiagLink’s initial software covers a single brand, Autel offers the option to purchase additional brand-specific software for around $10 per brand. This makes it a cost-effective solution if you primarily work with one vehicle brand or are willing to expand its capabilities gradually. For users needing multi-brand coverage, the Autel MD806, priced around $200, presents a different approach. Although it exceeds the $100 budget, the MD806 provides multi-brand compatibility without requiring separate software downloads for each brand. It also includes lifetime software updates, ensuring ongoing functionality, though “lifetime” typically refers to the tool’s support lifespan.
Considering features and price, the Autel DiagLink stands out as a top recommendation for the best OBDII scan tool under $100 for users focused on a single vehicle brand. It delivers significant diagnostic capabilities beyond basic OBDII reading, making it a valuable tool for both routine maintenance and more complex troubleshooting. For those requiring multi-brand diagnostics, exploring options in higher price ranges like the Autel MD806 might be necessary.
