Harding Performance/TVS DSG Software – 7 Speed DQ380/381

Harding Performance/TVS DSG Software – 7 Speed DQ380/381




The DQ380/381 first made its’ appearance on Australian shores in the updated 2017 S3 and MK7.5 Golf R/GTI Performance. The DQ381 is the 4 wheel drive version of the DQ380.

This gearbox is a smaller version of the DQ500, which can be found on the Audi RS3/TT-RS.

The software is jointly developed by Harding Performance and TVS Engineering to work seamlessly with Racingline Performance OEM+ ECU software.

Our highly developed DSG software is unique in the marketplace, even though we can do near “miraculous” things to sort out driveability issues, increase torque holding, and in some cases fix shuddering caused by programming & wear. The software WILL NOT:
⦁ Repair damaged or faulty mechatronics units
⦁ Recover slipping clutches or repair slipping clutches
⦁ Repair worn gear sets or compensate for poorly serviced transmissions
⦁ Will not work with modified engine software, engine components & DSG hardware unless we deem the software & components to be 100% compatible before purchase of the DSG Software.
⦁ As the software is custom produced for each vehicle and set of specifications, it is not returnable.
