Big news! can now unlock the DQ381 G2 gearbox via the RacingLine Server - with no mechanical changes needed, no hardware mechatronics swaps, no third-party tools, no transmission strip-downs - and minimal waiting!
Until now, the latest 2021+ locked DSG transmission control units have prevented TCU tuning access. That all changes with the new RacingLine CommsLink Cable. At last, you’ll be ready to flash RacingLine TCU software into your 2021+ Volkswagen, Audi, Cupra or Skoda DQ381 G2 TCU with the locked “401” boot loader.
