CarCoding vs Motorvet

CarCoding is a vehicle fault diagnosis and ECU coding app for ELM327 OBD2 scanners. Read and clear fault codes, view live data, reset service indicators, inspect used vehicles, and unlock hidden features — all in one OBD2 app. Plug in a Bluetooth (BLE) or Wi-Fi adapter, connect to your vehicle's control units in seconds. Find out why the check engine light is on, clear fault codes, watch live data, unlock hidden features. ▸ OBD2 DIAGNOSTICS • FAULT CODE READING AND CLEARING (DTC) Read and clear OBD2 fault codes — standard P-codes plus manufacturer-specific B, C and U codes. Engine, transmission, ABS, airbags and body modules in a single scan. Descriptions in plain language. • AI FAULT ANALYSIS What does "P0420" mean? Built-in AI explains the likely cause, urgency and what to check first — no jargon. • LIVE ENGINE ANALYSIS Measure fuel trim and oxygen sensor response at idle and under load; the app diagnoses vacuum leaks, fuel supply issues and sensor faults from the numbers. • USED CAR CHECK AND INSPECTION READINESS Were fault codes cleared before sale? Permanent fault codes, readiness monitors and distance driven since codes were cleared on one screen. Mode 06 tests give early warning before a fault code is set. ▸ LIVE DATA AND GAUGES • DIGITAL GAUGE PANEL Track RPM, coolant temperature, oil temperature, boost pressure, fuel trim and battery voltage in real time. Design your own gauges, record drives, export OBD2 logs. • APPLE CARPLAY AND SIRI Speed, RPM, engine temperature and battery voltage on your car's screen — with active fault codes and threshold alerts. Ask Siri: "What's my engine temperature?" • TRIP COMPUTER AND PERFORMANCE TEST Real-time and average fuel consumption, trip cost, distance and speed summary. Measure 0-100 km/h, quarter-mile and braking tests on closed track. • BATTERY, HYBRID AND DPF HEALTH Check battery health from the voltage drop while cranking. Battery status on hybrids and EVs; DPF differential pressure, regeneration status and AdBlue level on diesels. ▸ SERVICE RESET AND MAINTENANCE • OIL, EPB, DPF, SAS AND TPMS RESET Oil change reset, electric park brake (EPB) service mode, DPF regeneration, steering angle sensor (SAS) calibration and TPMS reset — with pre-flight RPM and voltage checks. • ACTUATOR TEST AND EXTENDED SENSORS On supported models, start and stop actuators directly from the app. Read vehicle-specific signals: charge percentage, module temperatures, oil life and more beyond standard OBD2. ▸ ECU CODING AND HIDDEN FEATURES • CODING Read and back up ECU coding data, then switch hidden factory features on or off: mirror folding on lock, seatbelt chime, gauge sweep, headlight behavior. Expert Mode offers direct hex/byte access. • BRAND SUPPORT The most complete coding support is on BMW and MINI. Long coding and adaptation on VW, Audi, Skoda, Seat and Cupra; telecoding on Peugeot, Citroën, DS and Opel; module coding on Ford, Fiat, Alfa Romeo, Jeep, Renault and Dacia; reading and analysis on Hyundai, Kia, Toyota and many more brands. Options vary by model. ▸ MORE • MOTORCYCLE AND TRUCK DIAGNOSIS K-line fault diagnosis and live data on motorcycles; active and historical faults plus live values over J1939 on trucks and buses. • REMOTE SUPPORT Open a support session from within the app; our team inspects your vehicle live through your phone. • 32 LANGUAGES Interface, fault code descriptions and coding labels in 32 languages. • COMPATIBILITY All OBD2-compliant vehicles (gasoline 2001+, diesel 2004+); quality ELM327 Bluetooth and Wi-Fi adapters. ▪ Coding and service resets write data to control modules. CarCoding backs up your data first — keep the ignition on and stay connected during the process. OBD2 scanner, car diagnostic tool and coding tool in one app. Download CarCoding.

Motorvet turns your iPhone and a Bluetooth LE OBD2 adapter into an easy-to-understand diagnostic tool for your car. Plug the adapter into the OBD port, connect it in the app and run a Quick Scan: the app reads the standard OBD-II/EOBD data your car reports and explains it in plain language. Reading and explaining trouble codes is free. QUICK SCAN • Stored, pending and permanent trouble codes • Check-engine light status and emissions readiness • Freeze frame data and the VIN, when the car reports them • Live values such as coolant temperature, system voltage and fuel trims CLEAR RESULTS Each scan ends with one of four summaries, such as "Further inspection recommended", based only on data available through the OBD port at the time of the scan. Every flagged item explains "Why this is flagged"; common generic codes get a plain-language description. USED CAR CHECK Park the car, ask the seller for permission and start the check. Enter the dashboard mileage, add a photo and notes if you like, and see what deserves a closer look: incomplete readiness monitors, a recent diagnostic memory reset, permanent codes without an active fault and pending codes. These are signals, never proof. The on-screen review is free; the shareable PDF report needs Pro or a one-time Used Car Report. LIVE DATA, HISTORY AND TRENDS See live values (Simple view free, Advanced view with Pro). With Pro, scans are kept per vehicle: compare scans for new, resolved and remaining codes and follow trends such as system voltage. Do not interact with the app while driving. DEMO MODE No adapter yet? Try the app with clearly labelled demo data. PRIVATE BY DESIGN No account, no ads, no tracking. Your vehicle data (VIN, codes, scans, mileage, photos and notes) stays on your iPhone. WHAT YOU NEED • A Bluetooth LE OBD2 adapter (ELM327/STN-compatible), sold separately. Connect it in the app, not in iOS Settings. • Classic Bluetooth adapters (paired in Settings with PIN 1234), Wi-Fi and USB adapters are not supported. • A car with OBD-II/EOBD: in the EU generally petrol cars from about 2001 and diesels from about 2004, in the US from 1996. Some cars report fewer values, electric cars little or none. US cars that use only the newer SAE J1979-2 protocol are not supported yet. • Compatible adapters: https://motorvet.taleppo.com/adapters LIMITS Standard engine and emissions data only: no ABS, airbag or transmission details, no coding or service resets; manufacturer-specific codes appear as raw codes. Clearing codes, the only write function, needs your confirmation, the engine off and the car stationary, and is never offered in a Used Car Check. FREE AND PRO • Free: Quick Scan, code explanations, readiness, freeze frame, Simple live data, one vehicle, the Used Car Check on screen and clearing codes. • Pro (subscription, monthly or yearly): unlimited vehicles, full history, comparisons, trends, advanced live data and unlimited PDF reports, including Used Car Reports. • Used Car Report (one-time purchase): the PDF report for one Used Car Check on this iPhone. As a consumable it cannot be restored on another iPhone or after reinstalling the app, and unused report credits are lost when the app is deleted. Export the PDF to keep it. Payment is charged to your Apple Account at confirmation of purchase. Pro renews automatically unless cancelled at least 24 hours before the end of the current period; renewal is charged within the last 24 hours of the period. Manage or cancel it in your Apple Account settings; deleting the app does not cancel the subscription.
