Diagnose and resolve issues in your BMW with the bimmer-tool app. This powerful tool allows you to read and clear fault codes, initiate DPF regeneration, access real-time engine data, and much more. While functionality is somewhat limited for pre-2008 models (a K+DCan USB cable is recommended for optimal performance; wireless ELM adapter connectivity may be unreliable or incomplete), bimmer-tool provides comprehensive diagnostics for a wide range of BMW vehicles.
Important: A reliable OBD adapter is crucial. We recommend the following:
- 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
