The wait is over! The VAG DQ381 transmission with the 401 bootloader has locked tuners out of this transmission since it first started showing up on vehicles in 2022+. Now, with the AutoTuner Tool you can unlock the OBD port on the bench, without removing the transmission controller from the vehicle, and flash your favorite tune! Just make sure you use our new DQ38x harness or if you already own our DSG kit, you're also ready go to!
