Take full control of your car with CarCoding — an all-in-one OBD2 scanner, diagnostics and ECU coding app. Plug in any ELM327 Bluetooth (BLE) or Wi-Fi adapter and reach your vehicle's control units in seconds. Find out why the check engine light is on, clear fault codes, watch live engine data, and explore the hidden features your car shipped with. ▸ WHAT YOU GET • PROFESSIONAL OBD2 DIAGNOSTICS Read and clear DTC fault codes — standard P-codes plus manufacturer-specific codes. Check readiness monitors before an emissions test and scan multiple control units, not just the engine. • AI REPAIR ASSISTANT What does "P0420" actually mean? The built-in AI explains the likely cause, how urgent it is, and what to check first — in plain language, no jargon. • LIVE DATA & DIGITAL GAUGES Track RPM, coolant and oil temperature, boost pressure, fuel trim, battery voltage and more on customizable low-latency gauges. Record a session and export the log. • APPLE CARPLAY & SIRI CarCoding now runs on your car's screen. CarPlay lists live values in real time — speed, RPM, engine temperature, battery voltage and more — shows active fault codes, and alerts you when a value goes beyond a safe range. And you can just ask Siri: "What's my engine temperature?" • ECU CODING & HIDDEN FEATURES Read your control unit's coding data, back it up, and explore factory options such as mirror folding on lock, seatbelt chime, gauge sweep and lighting behavior. Expert Mode gives direct hex/byte access for advanced users. • VEHICLE COMPATIBILITY Diagnostics work on every OBD2-compliant car (US 1996+, EU petrol 2001+, diesel 2004+). Coding depends on brand, model and equipment — support is deepest on BMW F-series; on many other brands coding data can be read and analyzed but not written. • SUPPORTED ADAPTERS Works with quality ELM327 Bluetooth Low Energy (BLE) and Wi-Fi OBD2 adapters. ▪ Coding writes data to control modules. CarCoding backs up your data first — keep the ignition on and the connection alive during the process. Become the master of your own garage. Download CarCoding.
