Choosing the right OBD2 code reader can be confusing, especially with numerous options available from Autel, a leading brand in automotive diagnostics. The Autel AutoLink series, including the AL301 and AL329, offers affordable solutions for basic vehicle diagnostics. But what exactly differentiates these two popular models, and is the Autel Autolink Al329 Pro Auto Scan Tool the right choice for you?
This comprehensive comparison dives deep into the Autel AL301 and AL329, analyzing their functions, hardware specifications, and price points. We aim to provide you with a clear understanding of each tool’s capabilities to help you make an informed decision.
Autel AutoLink AL301 Overview
The Autel AutoLink AL301 is designed as an entry-level OBD2 code reader, ideal for DIYers and those needing a simple tool to diagnose basic check engine light issues. It’s user-friendly and focuses on essential functions, allowing users to read and clear diagnostic trouble codes (DTCs) in OBD2 compliant vehicles manufactured from 1996 onwards. The AL301 also provides crucial Vehicle Identification Number (VIN) information and checks the status of OBD II Readiness Monitors (I/M Monitors) for emissions testing.
Autel AutoLink AL329 Overview
Building upon the foundation of the AL301, the Autel AutoLink AL329 offers enhanced functionalities, making it a more versatile autel autolink al329 pro auto scan tool in the basic code reader category. It retains the core features of reading and clearing DTCs but adds valuable capabilities like the patented One-Click I/M readiness key for quick emissions checks. The inclusion of AutoVIN technology significantly speeds up vehicle identification and DTC definition, especially for manufacturer-specific codes. Furthermore, the AL329 displays the I/M readiness monitor status, essential for inspection and maintenance readiness tests.
Autel AL301 vs AL329: Functionality Showdown
When comparing the Autel AL301 and AL329 in terms of functionality, the AL329 clearly emerges as the more feature-rich auto scan tool. While both devices excel at the fundamental task of reading and erasing DTCs, the AL329 expands its diagnostic reach with several key additions.
| Feature | Autel AL329 | Autel AL301 |
|---|---|---|
| Read MIL Status | √ | – |
| One-Touch I/M Readiness Key | √ | – |
| View Freeze Frame Data | √ | – |
| View Live Data | √ | – |
| Read/Erase DTCs | √ | √ |
| View Vehicle Information | √ | – |
| AutoVIN for Quick DTC Definition | √ | – |
| Vehicle Coverage | OBDII Compliant Vehicles (1996 & Newer) | OBDII Compliant Vehicles (1996 & Newer) |
The AL329 boasts the ability to Read MIL Status, indicated by the check engine light, providing immediate insight into the vehicle’s diagnostic status. Its One-Touch I/M Readiness Key simplifies emissions testing, a feature absent in the AL301. Moreover, the AL329 can View Freeze Frame Data, capturing critical vehicle parameters at the moment a DTC is triggered, and View Live Data, offering real-time insights into sensor readings and vehicle performance. The inclusion of AutoVIN in the AL329 drastically reduces diagnostic time by automatically identifying the vehicle and quickly accessing code definitions. While the AL301 is capable of performing OBD II Readiness Monitors (I/M Monitors) inspection, it lacks the convenient one-touch access and the additional data viewing capabilities of the AL329.
Hardware and Design Differences
In terms of hardware, the Autel AL329 pro auto scan tool presents a more advanced user interface compared to the AL301. The most notable difference lies in the display.
| Feature | Autel AL329 | Autel AL301 |
|---|---|---|
| Display | TFT color display (220 x 176 dpi) | Backlit LCD, 2 lines, 8 characters each |
| Operating Temp | 0 to 60°C (32 to 140 F°) | 0 to 50°C (32 to 122 F°) |
| Storage Temp | -20 to 70°C (-4 to 158 F°) | -20 to 70°C (-4 to 158 F°) |
| External Power | 8.0 to 18.0 V (Vehicle Battery) | DC12V (Vehicle Battery) |
| Dimensions (LWH) | 120.9 x 68.4 x 18 mm (4.76” x 2.69” x 0.71”) | 110 x 69 x 18 mm (4.33” x 2.72” x 0.71”) |
| Weight | 155.2 g (0.342 lb.) | 0.153kg (0.337b) |
The AL329 features a TFT color display, offering a more visually appealing and informative user experience with a resolution of 220 x 176 dpi. In contrast, the AL301 utilizes a basic backlit LCD with two lines, displaying 8 characters per line. While functional for basic code reading, the AL301’s display is less intuitive for navigating menus and viewing data compared to the AL329’s color screen. The operating temperature range is slightly wider for the AL329, although both tools are designed for typical automotive environments. Physically, the AL329 is marginally larger and heavier than the AL301, but these differences are negligible in practical use.
Price Point Comparison
Price is often a deciding factor when choosing between diagnostic tools. The Autel AL301 is positioned as the more budget-friendly option, typically priced around US $25. The Autel AL329, with its enhanced features and color display, comes at a slightly higher price of approximately US $40. This $15 price difference reflects the added functionalities and improved hardware of the AL329.

Summary: Which Auto Scan Tool is Right for You?
In summary, the Autel AutoLink AL329 is effectively an upgraded version of the AL301, offering more features and a better user experience. Both are basic OBD2 code readers primarily designed for reading and erasing codes and accessing vehicle information. However, the autel autolink al329 pro auto scan tool provides additional diagnostic capabilities such as One-Touch I/M Readiness, Freeze Frame Data, Live Data, and AutoVIN, presented on a more user-friendly color display.
The AL301 excels in its simplicity and affordability, making it suitable for users who only need basic code reading and clearing functions. If your primary goal is to turn off the check engine light and you are looking for the most economical solution, the AL301 is a capable tool.
However, for users who desire more comprehensive diagnostic insights, quicker vehicle identification, and a more modern interface, the AL329 is the better choice. The added features of the AL329 justify its slightly higher price, offering greater value and versatility for diagnosing common vehicle issues.
Ultimately, the best choice depends on your individual needs and budget. If you need a basic, no-frills code reader, the AL301 is sufficient. But if you are willing to invest a little more for enhanced functionality and ease of use, the Autel AL329 pro auto scan tool is a worthwhile upgrade. Consider your diagnostic needs and budget to determine which of these Autel AutoLink scanners best suits you.
