BTK-Auto for Europe

Android OBD-II diagnostics for cars across Europe

BTK-Auto gives drivers, independent garages and mobile mechanics a practical Android diagnostic workflow for vehicles commonly seen across European roads. Start with a free, read-only Basic Scan and unlock advanced diagnostics only when you need them.

We do not hide compatibility behind a blanket “works on everything” claim. Advanced functions depend on the vehicle, ECU, protocol and adapter, so the capability matrix stays part of the buying decision.

Built around European workshop reality

MIXED FLEETS

One Android workflow

European workshops see mixed brands, model years and powertrains every day. BTK-Auto keeps the first diagnostic pass portable: phone, compatible adapter, scan, evidence.

READ-ONLY FIRST

Free Basic Scan

Read standard OBD-II fault information without changing vehicle settings. That makes Basic Scan useful for an initial check before deciding whether deeper work is justified.

NO FAKE PARITY

Compatibility stays explicit

Advanced module diagnostics, service functions and controlled writes are only useful when the vehicle actually supports them. BTK-Auto documents those boundaries openly.

European markets and vehicle mix

BTK-Auto is positioned for drivers and workshops working with vehicles across the European market, including the countries below. Country names describe the market focus, not a promise that every ECU on every vehicle is supported.

European OBD-II diagnostics FAQ

Will BTK-Auto work on every European car?

No diagnostic app can honestly promise universal support. Standard OBD-II availability and advanced ECU functions vary by vehicle, model year, ECU, protocol and adapter. BTK-Auto keeps those limits visible instead of claiming dealer-tool parity.

Can I try BTK-Auto before paying?

Yes. Basic Scan is free and read-only. It can read standard stored and pending OBD-II fault codes plus VIN, MIL status and voltage when the vehicle exposes them. Full Access unlocks the advanced workflow.

What adapter do I need in Europe?

BTK-Auto is built for compatible classic Bluetooth ELM327-style adapters on Android. Adapter quality matters: very cheap clones can misreport capabilities, disconnect under load or fail on some vehicles.

Does vehicle communication go through the cloud?

No. Vehicle communication stays on the Android device. The BTK-Auto website is used for account access, billing, licence verification and APK delivery.
