1. What Is BMW Carly and How Does It Use Standard OBD2?

BMW Carly is a mobile app and adapter combination that allows BMW owners to diagnose, customize, and maintain their vehicles using a smartphone or tablet. It primarily interfaces with your BMW through the standard OBD2 (On-Board Diagnostics II) port, a universal interface found in most modern vehicles. According to the Environmental Protection Agency (EPA), OBD2 was standardized in 1996 in the United States to monitor vehicle emissions.

1.1 How BMW Carly Utilizes OBD2

The OBD2 port provides access to various vehicle systems, allowing Carly to read diagnostic trouble codes (DTCs), monitor live data, and perform coding functions. The Carly adapter plugs into the OBD2 port and communicates wirelessly with the Carly app on your mobile device via Bluetooth.

3.4 Coding Risks

While Carly makes coding relatively easy, there’s always a risk of causing unintended issues if you’re not careful. Incorrect coding can lead to malfunctions or even damage to vehicle systems.
