DQ38x/AL552/AL952 TCU UNLOCK

Starting with 2022+ Volkswagen and Audi vehicles, many were equipped with factory-locked “401” bootloader TCUs, preventing conventional OBD flashing and limiting TCU tuning options. We now offer professional TCU unlocking in Brantford, Ontario, giving supported vehicles access to TCU tuning through compatible tuning platforms.
