Many car owners rely on OBD2 scanners for diagnostics and troubleshooting. Brands like Actron, available at retailers such as Autozone, are popular choices. These tools can be incredibly helpful, offering features like live data and detailed trouble code information. For general use, tools like the Actron 9580A, often purchased from Autozone due to competitive pricing and accessibility, can seem like a great solution.
However, BMW owners need to be aware of a potential compatibility issue with certain OBD2 connectors, specifically those found on some Actron scanners purchased from Autozone. While these scanners may function effectively on a variety of vehicles, the design of the OBD2 connector itself can cause problems when used with BMW models.
The issue lies in a small bar present on the end of some OBD2 connectors. This bar, intended to secure the connection in various OBD2 ports, can become a hindrance in certain BMW vehicles. The OBD2 port in some BMWs features a plastic pin designed to slide into a slot on the connector. When this bar is present, it obstructs the pin, preventing proper connection and, more alarmingly, making removal extremely difficult.
One BMW owner’s experience highlights this problem vividly. After purchasing an Actron 9580A scanner from Autozone, they were initially impressed with its features when tested on their BMW. However, upon attempting to disconnect the scanner, they found it was completely stuck. The plastic pin in the BMW’s OBD2 port had become lodged against the bar on the Actron connector.
The struggle to remove the connector was significant, taking nearly forty minutes and requiring partial disassembly of the under-dash panel to access the OBD2 port. Even with direct access, visualizing the point of obstruction remained impossible. Ultimately, careful prying with screwdrivers and persistent wiggling were needed to finally detach the tool, raising concerns about potential damage to both the OBD2 port and the vehicle’s interior.
To prevent this frustrating and potentially damaging situation, a simple modification can be performed on the Actron OBD2 connector. By carefully removing the obstructing bar on the connector, you can ensure smooth compatibility with your BMW’s OBD2 port. This modification allows the plastic pin in the BMW port to slide freely as intended, preventing the connector from becoming trapped.
Before using an Actron OBD2 scanner purchased from Autozone on your BMW, especially models where the OBD2 port design is similar to the one described, it is advisable to inspect the OBD2 connector. If you notice a bar across the notch, consider carefully removing it. This proactive step can save you from a significant headache and potential damage, ensuring a smooth and trouble-free diagnostic experience with your BMW.
