Odometer Adjustment for Mercedes and MQB VAG
The OBDSTAR X300M is a hand-held cluster calibration tool built around an ARM high-speed chip for fast, stable and anti-jamming operation. It connects through the OBD2 socket and supports mileage correction on Mercedes-Benz and MQB-platform VAG vehicles. English is the only available language and registration with dealer code 860755B1 is required before first use.
Passive Cooling and Low Power Draw
The unit has no active cooling; its integrated structure is designed to be crack-resistant, shock-resistant and durable in high and low temperatures. Power comes from the vehicle OBD2 port, so there is no external supply and no fan noise during normal operation. The TF-card upgrade slot is accessed without opening the case, keeping the enclosure sealed against dust.
Updates Ended in 2021
Software updates were suspended after June 2021 and the tool cannot work on most vehicles from 2017 onward. Buyers needing coverage for newer models must choose a different platform. Always verify your specific vehicle against the supported car list before purchase.

Questions about this item
How do I install the OBDSTAR X300M, and what step is often missed?
Connect the OBDSTAR X300M to the vehicle via the OBD2 socket, then register the unit using dealer code 860755B1 or 0086A002 before first use; skipping registration is the common error.
What maintenance will the OBDSTAR X300M need later?
The tool receives updates via TF card, but updates were suspended after June 2021, so no further software maintenance is possible; only physical care of the shock-resistant housing is required.
What limit appears first during sustained use of the OBDSTAR X300M?
The tool cannot work on most vehicles from 2017 onward because updates stopped in 2021, so vehicle coverage is the hard limit encountered in daily use.
