bimmer-tool Lite

This guide explains how to use bimmer-tool to diagnose and service your BMW. This app reads and clears fault codes, initiates DPF regeneration, displays engine live data, and more.

Important Note: A reliable OBD adapter is crucial. K+DCan (recommended, especially for pre-2008 models), ENET (for F/G series), or the following Bluetooth/WiFi adapters are suggested:

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

App Capabilities:

• DPF regeneration status and details
• DPF regeneration initiation
• DPF adaptation value reset (post-filter replacement)
• Exhaust backpressure readings
• Injector adjustment readings
• Air mass, intake manifold pressure, and fuel pressure (actual vs. expected)
• Data logging to CSV
• Battery replacement registration (without altering battery properties)
• Resetting short-circuit-blocked lamp circuits
• Oil/brake service and interval resets**

Supported OBD Adapters:

• K+D-Can USB (recommended; requires USB-OTG cable)
• ENET cable/WiFi adapter (recommended for F & G series; needs USB-C to Ethernet adapter)
• ELM327 Bluetooth (may be slower; only genuine or PIC18-based adapters are compatible; may not work with older engines)
• ELM327 WiFi (potentially less stable; may require disabling mobile data)

Quick Start:

1. Connect the adapter to the OBD II port.
2. Turn the ignition on.
3. Connect the adapter to your phone (USB via USB-OTG, Bluetooth pairing [PIN usually 0000 or 1234], or WiFi [disable mobile data]).
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 (Pre-2008 models and E46/E39/E83/E53): K+DCan cable is required; only the engine ECU is supported. Wireless ELM adapter connection may fail.

Troubleshooting:

• "No response" error (pre-2007 models with BT/WiFi): Try selecting "ATWM" in advanced connection settings.
• No connection: Force-stop diagnostic apps (including bimmer-tool), restart your phone, and try again.

Permissions: Storage (for USB adapters), Photos/Media/Files (for CSV creation), Bluetooth access, network access (for WiFi adapters). Location access is not used.
