bimmer-tool: Your BMW's Diagnostic Companion

bimmer-tool empowers you to diagnose and resolve issues in your BMW vehicle. This app provides capabilities to read and clear fault codes, initiate Diesel Particulate Filter (DPF) regeneration, monitor engine live data, and more.

Compatibility Notes:

For BMW models manufactured before 2008, functionality is somewhat limited. A K+DCan USB cable connection is strongly recommended. Wireless ELM adapter compatibility may be inconsistent or feature-restricted for these older models.

Essential: A Reliable OBD Adapter

This application necessitates a dependable OBD adapter. The following are recommended:

• K+DCan cable: Highly recommended, offering the most reliable connection. Requires a USB-OTG cable.
• ENET adapter (F/G series): Recommended for F and G series BMWs. Requires a USB-C to Ethernet adapter.
• Vgate vLinker MC/FS/BM/FD: https://www.vgatemall.com/products/
• UniCarScan UCSI-2000/USCI-2100: Set to D-Can mode: MODE2. https://www.wgsoft.de/shop/obd-2-komplettsysteme/unicarscan/114/unicarscan-ucsi-2000-diagnoseadapter, https://www.bmdiag.co.uk/unicarscan-ucsi-2000-bluetooth-obd2-adapter

• Air mass, intake manifold pressure, and fuel pressure readings (actual and expected).
• Data logging to CSV files.
• Battery replacement registration (without altering battery properties).
• Resetting lamp circuits blocked by short-circuit errors.
• Oil/brake service and interval resets.

Supported OBD Adapters Summary:

• K+D-Can USB: Most reliable.
• ENET cable/WiFi Adapter: Ideal for F & G series.
• ELM327 Bluetooth/WiFi: May be slower and less stable than USB; genuine ELM327 or PIC18-based adapters are recommended. Older engine compatibility may vary.

Quick Start Guide:

1. Connect the adapter to the OBD II port.
2. Turn the ignition on.
3. Connect the adapter to your phone (USB, Bluetooth, or WiFi, depending on your adapter).
4. Launch the app, select your car's model and year.
5. Choose your connection type, adapter type, and communication protocol.
6. Tap "Connect."

Limitations:

For pre-2008 models and certain chassis (e46/e39/e83/e53), K+DCan cable connection is required, and only the engine ECU is supported. Wireless ELM adapter connection may be unsuccessful.

Troubleshooting:

• "No response" error (pre-2007 models with BT/WiFi): Try selecting the ATWM option in advanced connection settings.
• No connection: Ensure correct adapter and protocol settings. Force-stop diagnostic apps (including bimmer-tool) or restart your phone.

Permissions:

The app requests permissions for storage (USB adapter support), media access (CSV file creation), Bluetooth access, network access (WiFi adapters), and approximate location (theoretically possible via Bluetooth, but not used by the app).

Version 3.7.6-L (November 10, 2024):

• Diesel idle speed adjustment.
• Throttle body control.
