What you can check
- Read a BMW or MINI check engine light before a specialist booking.
- Stay on a generic ELM327 instead of a single-brand scanner.
- Treat brand recognition as the start of the job, not the whole job.

BMW diagnostic app for Android
BTK-Auto recognises BMW and MINI as one family. A 1 Series, 3 Series or MINI can start with the same free Basic Scan as any other supported car: codes, VIN, lamp status and voltage when the ECU exposes them.
Full Access adds live data and supported diagnostic actions for £4.99 a month or £49.99 a year. That is not BMW dealer software, and it is not a coding catalogue for convenience features. What answers depends on the model year, the ECU and the ELM327 adapter.
Use classic Bluetooth. A BLE-only adapter is outside this release.
What this does not promise
- Replace BMW dealer diagnostics.
- Unlock every hidden BMW or MINI feature.
- Cover every chassis with the same module list.
