The Autel AP200, a compact and budget-friendly OBD2 scanner, offers impressive diagnostic coverage for Mercedes vehicles, including compatibility with the 38-pin adapter. This article explores the AP200’s functionalities, highlighting its performance on various Mercedes models like the W210, W163, and W164. We’ll delve into its capabilities, limitations, and compare it with the AP200M and professional diagnostic tools.
Autel AP200 vs. AP200M for Mercedes Diagnostics
Both the Autel AP200 and AP200M are popular choices for DIY car enthusiasts and professional mechanics. However, key differences exist in their subscription models and long-term costs. The AP200 offers a lifetime subscription for the first selected car brand, meaning no annual fees for that specific make. Additional brands can be added for a yearly fee of $21.99. The AP200M, on the other hand, provides only a one-year subscription for a single brand, with subsequent renewals costing $19.99. For Mercedes owners, the AP200’s lifetime subscription model offers significant long-term savings.
Using the Autel AP200 with a 38-Pin Adapter on Mercedes
One crucial advantage of the Autel AP200 is its compatibility with the 38-pin adapter, essential for diagnosing older Mercedes models like the W210. While the AP200M can technically function with a 38-pin adapter, it might not provide full access to all ECUs on these older vehicles. The AP200, coupled with a 38-pin adapter, ensures comprehensive diagnostic coverage for a wider range of Mercedes models.
Real-World Testing of Autel AP200 on Mercedes
Extensive testing on a 2003 Mercedes ML320 (W163) and a 2000 Mercedes W210 demonstrated the AP200’s impressive diagnostic capabilities. Tests included reading and clearing fault codes, viewing live data from various modules (including ABS, ACC, and engine), performing readiness tests, and evaluating AC performance. The AP200 successfully diagnosed induced faults like a disconnected MAF sensor and a removed ABS fuse.
Autel AP200 Limitations on Mercedes
While the Autel AP200 offers extensive diagnostic functionality, it does have some limitations. It lacks bi-directional control (actuation of valves, components, etc.) and cannot access functions requiring HHT-WIN software, such as in-depth EGS (Electronic Gear Selector) data. For these advanced functions, professional diagnostic tools like the Autel MP808 or Mercedes-Benz Star Diagnostic System (SDS) are necessary.
Conclusion: Autel AP200 – A Powerful Tool for Mercedes Diagnostics
The Autel AP200 provides excellent value for Mercedes owners seeking a comprehensive and affordable diagnostic solution. Its 38-pin adapter compatibility, coupled with its lifetime subscription for the first car brand, makes it an attractive option for DIY enthusiasts and professionals alike. While it lacks some advanced functionalities found in higher-end scanners, its capabilities cover a wide range of diagnostic needs for Mercedes vehicles. For those seeking bi-directional control or access to HHT-WIN specific functions, investing in a more advanced tool like the Autel MP808 or SDS would be necessary.
