The OBDSTAR X300 DP Plus is not a dedicated mileage correction tool. It is a versatile immobilizer/programming tool that happens to support mileage adjustment on a specific, well-defined set of vehicles.

Final practical advice: Before purchasing or using the X300 DP Plus for a specific job, join an OBDSTAR user group, ask for real feedback on your exact car (year, cluster type, country spec), and always verify the tool’s supported list via the latest firmware on the device itself. Never assume support just because the make is listed. obdstar x300 dp plus mileage correction car list

OBDSTAR X300 DP Plus (specifically Package B and C) is a leading tool for cluster calibration and mileage correction, featuring a vehicle coverage list that extends through 2024 and 2025 . It shares the same specialized calibration system as the OBDSTAR Odo Master , focusing on OBDII-based adjustments. OBDSTARStore Core Supported Vehicle List (2024-2025 Updates)

The OBDSTAR X300 DP Plus is widely praised for its extensive coverage of Asian makes, particularly Toyota, Honda, Nissan, Hyundai, and Kia. For example, the device reliably corrects mileage on Toyota models from 2003 to 2019 via the OBD port without requiring cluster removal. Similarly, for the Honda Civic and Accord (2006–2015), the X300 DP Plus often completes the correction in under two minutes.
In the European segment, the device shows moderate success. It handles older Mercedes-Benz W203/W204 platforms effectively, as well as BMW E-series chassis (E46, E90) via the OBD port. For the Volkswagen Audi Group (VAG), the X300 DP Plus can correct mileage on MQB platform vehicles (Golf 7, Audi A3 8V) but frequently requires a bench connection or the addition of an external adapter. It is worth noting that support for French vehicles (Renault, Peugeot, Citroën) is available but often limited to models produced before 2018, with newer architectures requiring advanced programmer tools like the OBDSTAR F-401.
The OBDSTAR X300 DP Plus is an Android-based diagnostic tablet designed primarily for key programming and immobilizer functions. However, one of its core sub-functions is Odometer Correction.
Unlike standard OBDII scanners that only read data, the X300 DP Plus is capable of writing to the vehicle's dashboard microcontroller (MCU) and EEPROM via the OBD port. This allows technicians to rectify mileage discrepancies caused by dashboard replacements, instrument cluster swaps, or electrical faults.
