Diagnose and Maintain Your BMW with bimmer-tool: A Comprehensive Guide

bimmer-tool empowers you to read, clear fault codes, initiate Diesel Particulate Filter (DPF) regeneration, access engine live data, and perform various other functions on your BMW vehicle. However, functionality is somewhat limited for pre-2008 models, where a K+DCan USB cable is the recommended connection method. Wireless ELM adapter compatibility may be restricted or incomplete for these older vehicles.

Essential: A Reliable OBD Adapter is Crucial

Successful use of bimmer-tool hinges on a reliable OBD adapter. The following are recommended:

• Vgate vLinker MC/FS/BM/FD: https://www.vgatemall.com/products/
• UniCarScan UCSI-2000/USCI-2100: (Set D-Can mode to 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
• Carista: https://caristaapp.com/adapter
• Veepeak OBDCheck BLE: https://www.veepeak.com/product/obdcheck-ble

bimmer-tool Capabilities:

This app offers a wide range of diagnostic and maintenance capabilities, including:

• DPF regeneration status and detailed information.
• Initiating DPF regeneration.
• Resetting DPF adaptation values (post-filter replacement).
• Reading exhaust back pressure.
• Reading injector adjustments.
• Accessing actual and expected values for air mass, intake manifold pressure, and fuel pressure.
• Data logging to CSV files.
• Battery replacement registration (without altering battery properties).
• Resetting lamp circuits blocked by short-circuit errors.
• Resetting oil/brake service and change intervals**

Supported OBD Adapters:

• K+D-Can USB: Highly recommended for its reliability. Requires a USB-OTG cable.
• ENET cable/WiFi Adapter: Recommended for F and G series BMWs. Needs a USB-C to Ethernet adapter.
• ELM327 Bluetooth: Slower than USB; only genuine ELM327 or PIC18-based adapters are compatible. May not function with older engines.
• ELM327 WiFi: Potentially less stable than Bluetooth. May require disabling mobile data.

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).
4. Launch the app, select your car's model and year.
5. Choose the connection type, adapter type, and communication protocol.
6. Tap "Connect."

** Limitations for Pre-2008 Models and Specific BMW Series (e46/e39/e83/e53): These vehicles require a K+DCan cable, and only the engine ECU is supported. Wireless ELM adapter connection may fail.

Troubleshooting:

• "No response" error: For pre-2007 models using a Bluetooth/WiFi adapter, try enabling the ATWM option in advanced connection settings.
• No connection: If settings are correct, force-stop all diagnostic apps (including bimmer-tool) or restart your phone.

Permission Rationale:

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) Updates:

• Diesel idle speed adjustment.
• Throttle body control.
