Since 1994, OBD II has become a cornerstone in automotive diagnostics, much like how Pulp Fiction revolutionized cinema that same year. For anyone involved in automotive repair or vehicle maintenance, understanding OBD II codes is essential. Fortunately, accessing and interpreting these codes is becoming increasingly straightforward and affordable. Modern OBD II scanners not only read codes but also monitor your vehicle’s health and emissions status, empowering owners with valuable insights.
Autel, a well-known name in automotive diagnostic tools, recently provided their AutoLink AL629 scan tool for review. Priced around $169 and up, this tool promises a comprehensive diagnostic experience. After initial testing, the AL629 appears to be a solid, all-around option. Here are my first impressions of the Autel AutoLink AL629 as a diagnostic tool for everyday car owners and enthusiasts.
Premium Packaging and Build Quality
Right out of the box, the inclusion of a dedicated carrying case with the Autel AL629 is a notable positive. While more basic scanners might forgo this, at this price point, a protective case feels justified and adds to the overall value.
The build quality extends to the included OBD II cable. It’s noticeably robust and generously long, allowing for comfortable operation from either the driver’s or passenger’s seat while connected to the OBD II port, typically located in the driver’s footwell. This length is particularly useful if you need a second person to observe live data while you drive or perform tests. The cable connects to the top of the unit, a standard and practical design for these tools.
The AL629 itself feels lightweight yet substantial in hand. The large, clearly labeled buttons are a welcome design choice, making navigation intuitive from the moment you power it on. The unit also incorporates textured areas for enhanced grip and potential drop resistance. While it feels relatively light internally, the padded carrying case is still recommended for protection against drops, especially from workbench height.
Comprehensive Diagnostic Capabilities
Autel highlights the AL629’s ability to retrieve both generic OBD II codes and manufacturer-specific codes. This is crucial for deeper diagnostics beyond basic engine fault codes. The tool supports reading codes from the engine, transmission, ABS (Anti-lock Braking System), and SRS (Supplemental Restraint System, airbags) – covering essential vehicle systems. It also reads VIN (Vehicle Identification Number), CIN (Calibration Identification Number), and CVN (Calibration Verification Number).
Beyond basic code reading, the AL629 can display live data streams from the powertrain control module (PCM) and various vehicle sensors. It can record and playback this data, which is invaluable for diagnosing intermittent issues or analyzing sensor behavior over time. Furthermore, it checks emissions readiness monitors, essential for ensuring your vehicle will pass emissions testing.
The device features a 2.8-inch color LCD screen with a 320×240 resolution. The screen size and clarity are impressive, making it easy to read diagnostic information even in varying lighting conditions. Finally, the AL629 can be connected to a computer for printing data and downloading free software updates, ensuring the tool stays current with vehicle diagnostic protocols.
Real-World Testing and Further Exploration
The next step is to put the Autel AutoLink AL629 through more rigorous testing on different vehicles. I plan to use it on my 2002 Audi S4 and 2011 BMW 128i. These European brands are known for sometimes requiring dealer-level diagnostic tools for in-depth analysis. It will be particularly interesting to see how the AL629 compares to brand-specific software like INPA/ISTA for BMW and VCDS for Audi. The key question is whether a universal tool like the Autel AL629 can offer comparable functionality and save time and effort compared to manufacturer-specific software.
Pros:
- Comprehensive system coverage (Engine, Transmission, ABS, SRS)
- Reads generic and manufacturer-specific codes
- Live data streaming and recording
- Emissions readiness testing
- Durable build quality and included carrying case
- Easy-to-read color display
- Free software updates
Cons:
- Price point may be higher than basic OBD2 scanners
- Lightweight feel might raise concerns about drop durability (without case)
Conclusion:
The Autel AutoLink AL629 OBD2 scanner makes a strong first impression as a versatile and well-featured diagnostic tool. Its robust build, comprehensive capabilities, and user-friendly design make it a promising option for DIY mechanics and car owners seeking more than just basic code reading. Further testing will determine its long-term performance and value, especially when compared to more specialized diagnostic solutions. Stay tuned for a more in-depth review after extended use and testing on a wider range of vehicles.
