For BMW E60 enthusiasts looking to unlock their car’s hidden potential through coding, a reliable connection to your vehicle’s computer is paramount. Whether you’re aiming to personalize settings, diagnose issues, or enhance performance using apps like BimmerCode, a stable OBD2 connection is your first step. This guide will walk you through setting up a robust connection for your BMW E60 using an OBD2 cable and a Samsung converter, catering to both iPhone and Android users.
Understanding the Essentials: OBD2, ENET, and Your Devices
Before diving into the setup, let’s clarify the key components:
- OBD2 Cable: This cable connects to your BMW E60’s OBD2 port, typically located under the dashboard. It’s the physical interface for communication between your car and your device.
- ENET (Ethernet to OBD2) Cable: Specifically for BMW coding, ENET cables offer a faster and more stable connection compared to traditional OBD2 Bluetooth adapters.
- Samsung Converter (USB-C to Ethernet Adapter): For Android devices, particularly Samsung phones and tablets, a USB-C to Ethernet adapter is necessary to bridge the ENET cable to your device’s USB-C port. iPhone users will require a Lightning to Ethernet adapter.
- BimmerCode App (or similar): This popular app allows you to code various parameters in your BMW, from comfort features to lighting and beyond.
Step-by-Step Connection Guide for iPhone and Android
The following steps outline how to establish a connection using an ENET cable, OBD2 adapter, and the appropriate converter for your smartphone.
Preparing Your BMW E60
- Locate the OBD2 Port: Find the OBD2 port in your BMW E60. It’s usually situated under the dashboard on the driver’s side.
- Enter Auxiliary Mode: Put your BMW E60 into auxiliary mode. This means turning on the car’s electronics without starting the engine. Typically, you can do this by pressing the start button without pressing the brake pedal. You should hear the car’s systems power up.
Setting Up Your iPhone Connection
- Connect ENET to OBD2: Plug one end of your ENET cable into your OBD2 adapter and the other end into the ENET port on your car.
- Connect Lightning to Ethernet Adapter: Attach your Lightning to Ethernet adapter to the RJ45 end of the ENET cable. Do not connect to your iPhone yet.
- Disable Wireless Connections: On your iPhone, temporarily disable Wi-Fi, Cellular Data, and Bluetooth. It’s crucial to ensure these are fully disabled for a stable wired connection. Give your iPhone about 30 seconds after disabling these services to ensure they are properly shut down.
- Connect to iPhone: Now, plug the Lightning end of the adapter into your iPhone.
- Verify Ethernet Connection: Go to your iPhone’s Settings. You should see an “Ethernet” option appear in the menu, often between “Bluetooth” and “Wi-Fi”. If it doesn’t appear, try disconnecting and reconnecting the Lightning adapter.
- Renew DHCP Lease (If Necessary): Tap on “Ethernet,” then “USB 10/100 LAN.” Select “Renew Lease” and confirm. This step can help ensure your iPhone obtains an IP address for the connection.
Setting Up Your Android (Samsung) Connection
- Connect ENET to OBD2: Plug one end of your ENET cable into your OBD2 adapter and the other end into the ENET port on your car.
- Connect USB-C to Ethernet Adapter (Samsung Converter): Attach your USB-C to Ethernet adapter to the RJ45 end of the ENET cable. Do not connect to your Samsung device yet.
- Disable Wireless Connections: On your Samsung device, disable Wi-Fi, Mobile Data, and Bluetooth. Similar to iPhone, wait about 30 seconds for these services to fully disconnect.
- Connect to Samsung Device: Plug the USB-C end of the adapter into your Samsung phone or tablet.
- Verify Ethernet Connection (If Visible): Depending on your Android version, you might see an Ethernet connection status in your device’s settings under “Connections” or “Network & Internet.” The presence and location of this setting can vary by device and Android version.
Configuring BimmerCode and Connecting
- Open BimmerCode App: Launch the BimmerCode app on your iPhone or Android device.
- Initial Adapter Setting (Trick): Go to BimmerCode’s Settings (usually a gear icon). Temporarily change the adapter type to something other than “ENET Cable”—for example, “OBDLink CX.”
- Attempt to Connect (Expect Error): Return to the main screen of BimmerCode and tap “Connect.” You should get an error message, which is expected at this stage.
- Switch Adapter to ENET Cable: Go back to BimmerCode’s Settings and now select “ENET Cable” as your adapter type.
- Connect Again: Return to the main screen and tap “Connect” again.

Troubleshooting Common Connection Issues
- “Adapter Not Found” Error: Ensure your wireless connections (Wi-Fi, Cellular, Bluetooth) are completely disabled on your phone. Double-check that the ENET cable and adapters are securely connected. Restart the BimmerCode app and retry the connection process.
- “Vehicle Not Supported” Error: Verify that BimmerCode supports your specific BMW E60 model and production year.
- Intermittent Connection: A loose cable connection is often the culprit. Ensure all connections are firm. In rare cases, a faulty adapter or cable might be the issue.
Conclusion
Establishing a wired ENET connection to your BMW E60 using an OBD2 cable and a Samsung converter (or Lightning adapter for iPhone) provides a reliable foundation for coding and diagnostics. By following these steps, you can confidently use apps like BimmerCode to personalize your BMW and explore its advanced features. Remember to always exercise caution when coding your vehicle and consult reputable resources for coding parameters. Happy coding!
