Harding Performance DSG Software – 7 Speed DQ500


SKU: HP DSG DQ500 Categories: , Tags: ,


The DQ500 is widely known throughout the VW/Audi tuning community as one of the strongest transverse gearboxes – but it is not without it’s downsides and many benefits can be had from our special software.

Our driveability software package contains:

  • Optimised D mode shift program
  • Optimised S mode shift program
  • 1st gear activation at low speed by request
  • Smoother gear changes

Special performance package includes:

  • Raised maximum shifting RPM to accommodate engine tuning
  • Improved clutch clamping force capable of up to 700nm
  • Torque limit increased
  • Faster gear changes

For 2018-on RS3 an optional special launch control program can also be added to allow multi-RPM launch control and increased boost during LC.

Software updates from VW/Audi will not resolve these problems. Our software is not detectable.

Known issues and symptoms:

  • Excessive slip on the clutch in 2nd gear
  • Shifting at extremely low RPM’s (droning)
  • Slow reaction when accelerating

Four examples:

1. Better shifting strategy

When entering a curve or a roundabout, the DSG has not selected an appropriate gear. This creates poor throttle response when accelerating.

2. Maximum RPM (TDI’s)

The engine rev limit at full throttle goes up as high as 4700rpm. With our software we limit this to a more sensible lower RPM, which allows the car to accelerate faster and the lifespan of the engine and turbo can be increased. On a Transporter TDI, when combined with engine software, our DSG software can decrease fuel consumption and massively improve driveability.

3. Under revving

The DSG upshifts at extremely low RPM’s. Generally, when you are driving at 00kmh the DSG is already in 7th gear and between 1150rpm. When giving slight throttle the engine and gears start making audible vibration sounds during low RPM speeds. These sounds will become more noticeable over time if not fixed and will result in permanent flywheel damage. We can fix this problem by raising the shift RPM values and so reduce the frequent up and downshifts. The engine and DSG transmission will respond better and faster when applying throttle. Repair costs would be several times the cost of software. With a simple and affordable software package, your DSG will last longer and have better performance.

4. Sports mode

Many drivers find that the DSG in S mode does not drive very well. The DSG downshifts too early and the engine will rev high. What we do is lower the S mode to make it more suitable for driving in the city.

The software is developed by Harding Performance to work seamlessly with Harding Performance or 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.
