Diagnose and clear fault codes, plus check DPF status for BMW vehicles
bimmer-tool enables reading & clearing trouble codes, initiating DPF regeneration, monitoring live engine data, and more for your BMW.
For vehicles manufactured before 2008, functionality may be limited—we recommend using a K+DCan USB cable. Wireless ELM adapters may not support all features or connect properly with pre-2008 models.
Note: A quality OBD adapter is essential. We suggest K+DCan cables, ENET adapters (for F/G series), or these Bluetooth options:
- Vgate vLinker MC/FS/BM/FD https://www.vgatemall.com/products/
- UniCarScan UCSI-2000/USCI-2100: Configure to D-Can mode: MODE2 https://www.wgsoft.de/shop/obd-2-komplettsysteme/unicarscan/114/unicarscan-ucsi-2000-diagnoseadapter

- Carista https://caristaapp.com/adapter
- Veepeak OBDCheck BLE https://www.veepeak.com/product/obdcheck-ble
Key features include:
- Monitoring DPF regeneration status with detailed insights
- Initiating manual DPF regeneration
- Resetting DPF adaptation values (necessary after filter replacement)
- Reading exhaust gas pressure data
- Analyzing injector adjustment parameters
- Comparing actual vs. expected values for air mass, intake pressure, and fuel pressure
- Exporting diagnostic logs to CSV for comprehensive analysis
- Registering battery replacement without modifying battery settings
- Resetting short-circuit blocked lamp circuits
- Performing service resets for oil and brakes**
Compatible OBD adapters:
- K+DCan USB: Most reliable option (requires USB-OTG cable)
- ENET cable/WiFi Adapter: Ideal for F & G series (may need USB-C to Ethernet adapter)
- ELM327 Bluetooth: Slower than USB (only genuine ELM327/PIC18 adapters supported; limited compatibility with older engines)
- ELM327 WiFi: Less stable than wired options (sometimes requires disabling mobile data)

Getting started guide
1) Plug adapter into OBD II port
2) Switch ignition to ON position
3) Establish device connection:
* USB: Connect via USB-OTG cable—when prompted, select bimmer-tool
* Bluetooth: Pair adapter in phone settings (default PIN: 0000/1234)
* WiFi: Disable mobile data first—connect to adapter's WiFi network
4) Launch app, select your car model/year under 'Car' menu
5) Navigate to 'Connection' to configure adapter type and protocol
6) Tap 'Connect' to establish communication
**Compatibilty notes:
Pre-2008 models (including e46/e39/e83/e53) require K+DCan cable—only engine ECU diagnostics are supported (wireless ELM adapters often won't work).
Troubleshooting tips
- Intermittent 'No response' with BT/WiFi on 2007/older models? Try enabling ATWM in advanced connection settings
- Persistent connection failure? Force-stop all diagnostic apps (including bimmer-tool) or reboot your phone before retrying
