DQ-200 Gearbox
Models: All VAG models built in 2007-present with 1.0-1.9L engines.
The DQ200 is the world’s first and only DSG (7) with ‘dry coupling’. These gearboxes have many problems, in contrast to the predecessor DQ250.
The main problem is the excessive wear of the coupling. To this end, TVS developed special software in 2011. Without the use of this software, the gearbox will be irrevocably defective, so it will need to programmed as soon as possible. This software is unique and is not supplied by any other company than TVS and TVS Dealers.
With TVS / DSG software the DQ200 can be used up to 350 hp / 400 Nm.

Common Problems
We can adjust the early shift up on of the next gear to a higher speed. It is often noted by DSG owners that when the user wants to accelerate and nothing happens. This is because the DSG is busy with shifting calculations and thus has a higher acceleration pre-synchronized, but when accelerating, the DSG wants to switch to a lower gear, and creating time delay.
These occur because the DSG shift down at the wrong time. Easy fix with our software.
If you slow down in front of a traffic light, there is still a bit of noise coming out of the DSG. Sometimes the same sound can be heard when you go from position P to D, release the brake, and the car just rolls forwards. This sound is often gone after adjustment of the software, and usually at least a lot less audible.
The DSG shift down when you press the accelerator pedal, there is time delay because the DSG first shift down before the car accelerates. Especially a diesel with a lot of torque can better stay in the same gear and make use of the torque. You do not have the delay due to switching time, think of catching up quickly. This can be adjusted so that the DSG does not switch back each time, only if you push the pedal down to the ground for example, or do not switch back at all. This can be done in both the D and the S. Or we can, for example, change the S to a D, only without a kickdown / downshift function. The S is rarely used by TDI riders.● The S is far too extreme, the DSG shift extremely late and back too early
In some cases we adjust the S so that it becomes a slightly sportier D. The advantage is that the economy function of the D can continue to be used, in other words: The D remains enhanced original and the S becomes an improved D program.
● The DSG shift over at max rpm
The user sometimes wants to “hang” the motor in the limiter without switching it. We can adjust this so that for example in the D, S or M the DSG does not switch automatically. Some software versions already have this as standard.
● The car vibrates and drives shocking when the clutch is engaged or when switching over.
We can also solve this complaint for you. Contact us for more information.
● When accelerating, the DSG shoots out of the gear
This problem is also more common and we can solve it for you.
● The DSG does not shift properly at high rpm
This phenomenon often starts with switching from the 4 to the 5 full throttle. At approx. 4000 rpm you feel the engine what (fluctuating). Contact us for more information.
● Lazy DSG on D1-D2
D2 engaged too quickly.
● Shock when shifting from 5th to 6th gear
We only see this problem with the Golf / Passat / A3 with V6 engine. Contact us for the solution.
