The MX900 trades the MP808S’s coding capability for broader service-reset coverage — Autel’s page documents EPB reset, SAS calibration, DPF regeneration, and throttle relearn on top of standard code reading, at a similar price point to the MK808S. It doesn’t document ECU coding or module programming.
Good fit for: drivers who want the widest maintenance-reset coverage in Autel’s consumer line without paying for coding capability they won’t use.
