2dakika: OBD Car Diagnostics

2dakika is an OBD2 car diagnostic app. It reads your car's electronic memory through the 2dakika OBD-X1, a Bluetooth OBD2 device in the OBD port, and turns it into a plain-language Vehicle Health Report: faults and fault history, mileage records, battery and DPF status, and module part and software details. After a repair, you can clear fault codes right from the app.

The app works only with the 2dakika OBD-X1 device (sold at 2dakika.com and in the app), not with generic Bluetooth OBD2 adapters. It works with cars and light vans that use K-line or CAN.

WHAT'S IN THE REPORT
• Faults: Current faults and fault history, listed separately. Over 50,000 fault descriptions matched to the car's make, each with a severity (Priority, Warning, Info) and, where the engine computer stored it, the engine temperature, rpm and speed when the fault was recorded.
• Fault memory: Distance driven since the fault memory was last cleared, distance driven with the check engine light on, and the light's current status. Engine self-tests that came out of range.
• Mileage check: The odometer is compared with the mileage stored by modules such as the engine, transmission and ABS. Results are plain: "Mileage consistent", "Mileage mismatch — get it checked" or "Mileage inconsistent — possible rollback". When a comparison isn't possible, the report says so.
• Modules and part compatibility: Part number, software version, and build and programming dates for each module. Modules whose stored VIN belongs to another car are flagged.
• Vehicle condition: 12 V battery health where the car reports it, otherwise battery voltage. Battery health (SOH) and cell balance on supported EVs and hybrids. On diesels that report it: DPF ash and soot, regeneration history and filter replacement. Emissions readiness monitors.

CLEAR FAULT CODES
Tap "Clear fault codes" in the report's Current faults section to clear stored codes and the fault memory.
• Conditions: engine off, ignition on, battery at 12 V or more, within 30 minutes of the scan.
• You confirm first. Clearing doesn't fix the fault: if the problem persists, the code and the warning light come back. Emissions readiness monitors are reset.
• Key and immobilizer modules are never touched; mileage and the VIN are never changed.
• Every clear is recorded and shows up with its date in that car's later reports.
• Some modules may refuse to clear; results are shown module by module.
• For airbag or ABS warnings, see a workshop first; the decision to clear is yours.

SHAREABLE REPORT
Save the report as a PDF, or share it with a link or QR code and revoke the link anytime. The QR code on the PDF opens the original report on 2dakika; readings are signed by the device. Reports come in English or Turkish.

WHO IT'S FOR
• Used-car buyers: See the car's electronic records before you buy.
• Mechanics: Read the fault, clear it after the repair.
• Sellers and owners: Add the report to your listing.
• Dealers and fleets: Scan cars regularly.

COMPATIBILITY AND LIMITS
• Trucks, buses and Tesla are not supported.
• What can be read varies by car; some modules (for example, behind a security gateway) can't be reached. Missing data doesn't mean the car is faulty.
• The mileage comparison depends on the car's modules and is limited for many makes.
• Nothing is written to the car during a scan.
• The device firmware updates over the air through the app.
• Works with most makes, including Renault, Dacia, Fiat, Ford, Volkswagen, Peugeot, Citroën, Opel, Toyota, Hyundai and Kia.

PLANS
The free plan includes 10 scans a month. Pro (50 a month) and Business (unlimited) subscriptions are available in the app.

IMPORTANT
2dakika is a pre-check tool: the report is not a definitive finding and not a professional inspection report. It does not cover mechanical condition, accident/paint history, insurance damage (Tramer) or service records.
