Bosch DQ500 — a DSG automated-transmission control unit (VAG MQB/MLB); the firmware checksums are recalculated after editing.
This unit is found on дизельных и бензиновых vehicles Audi, Volkswagen (2014–2020) — a total of 10 models, among them Audi Q3, Volkswagen Passat, Audi Q3 RS, Audi RS3, Audi TT RS, Volkswagen Teramont.
Recalculation is needed after any calibration edit — DSG launch RPM raise, DSG torque limit increase, DSG kick-down threshold, Stage 1 DSG software: the checksum no longer matches, and the ECU throws an error or refuses the firmware.
Upload the modified file (MOD) and the original (ORI) — the tool compares them, finds the affected regions and recalculates only the required checksums, leaving the rest of the calibration untouched. The result is ready in a second and free; downloading the fixed .bin requires registration in the portal.
Other checksum plugins from the same manufacturer — open any of them to recalculate the checksum.
