Diagnose and Manage Your BMW's Diesel Particulate Filter (DPF) with bimmer-tool

bimmer-tool offers comprehensive diagnostics and management capabilities for BMW vehicles, including fault code reading and clearing, DPF regeneration initiation, and real-time engine data monitoring. Functionality is somewhat limited for pre-2008 models, which are best served by a K+DCan USB cable connection. Wireless ELM adapter compatibility may be restricted for these older vehicles.

Crucial Note: A reliable OBD adapter is essential. The app recommends:

• 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)

Key Features:

• DPF regeneration status and detailed information retrieval.
• DPF regeneration initiation.
• DPF adaptation value reset (post-filter replacement).
• Exhaust back pressure monitoring.
• Injector adjustment data access.
• Real-time and target values for air mass, intake manifold pressure, and fuel pressure.
• Data logging to CSV for detailed analysis.
• Battery replacement registration (without altering battery properties).
• Resetting short-circuit-blocked lamp circuits.
• Oil/brake service and interval reset.

Supported OBD Adapters:

• K+D-Can USB (recommended, most reliable; requires USB-OTG cable).
• ENET cable/WiFi Adapter (recommended for F & G series; requires USB-C to Ethernet adapter for wired connections).
• 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 for optimal performance).

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 via USB-OTG, Bluetooth pairing (PIN often 0000 or 1234), or WiFi connection).
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 (Pre-2008 Models & Specific BMW Series): K+DCan cable connection is mandatory; only the engine ECU is supported. Wireless ELM adapter connection may fail.

Troubleshooting:

• "No response" error (pre-2007 models with Bluetooth/WiFi): Try enabling 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: Storage (USB adapter support), Photos/Media/Files (CSV creation), Bluetooth access, Full network access (WiFi adapters), Approximate location (theoretically possible via Bluetooth, but not utilized by the app).

Version 3.7.6-L (November 10, 2024): Includes diesel idle speed adjustment and throttle body control.
