While the wet clutch DL501 S-Tronic system is known to be generally strong, reliable and easy to use, there are some known issues, which can hamper drivability, especially with tuned vehicles.
These include: Shifting gears while at too low RPM , aggressive / unsmooth take-off from a standstill, bump during braking just before coming to a standstill, clutch vibrations and slip, gearbox error messages on the dashboard, vehicle doesn’t want to move at all.
In the same way that ECU software optimises the way an engine performs, TVS’ gearbox (TCU) software does the same for the twin-clutch S-Tronic unit.
The programme removes unnecessary downshifts, allowing you to hold onto a gear for longer, but also increases the shifting speed, which provides a more responsive and enjoyable driving experience. The max shifting rpm is increased to 8000rpm and a special launch control function is also added.
With the clutch clamping force and torque limits both increased, the TVS DL501 Stage 4 software can handle up to 1000Nm on stock clutches.
As with all TVS Tuning software, full customisation is available, allowing S4 / S5 / S7 / RS4 / RS5 owners to tailor DL501 S-Tronic performance to their preferred driving style.
