Big news! Your RacingLine Software Dealer can now unlock the DQ381 G2 and ZF8 gearboxes via the RacingLine Server in minutes - 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 and ZF8 transmission control units have prevented TCU tuning access. That all changes with the new RacingLine CommsLink Cable. At last, your dealer will be ready to flash RacingLine TCU software into your 2021+ Volkswagen, Audi, Cupra or Skoda DQ381 G2 or ZF8 TCU with the locked "401" boot loader.
Right now, you need to visit your RacingLine Software Dealer for the unlock, but coming very soon, our home-unlock PDM CommsLink Cable is coming soon for PDM customers.
