This dual-clutch transmission is controlled with the use of electric motors instead of hydraulic valves of piston valves and the pump.This transmission uses the main tested advantage of mechanical gearboxes – the clutch is relocated to open space and wear products of clutches are immediately get out from the transmission without causing any harm. Neither planetary gears nor hydraulic switch control are used for this purpose.

Technical issues and repair guidelines

Gear shifting is implemented by two fork connectors controlled from a closed small hydraulic Mechatronic which may contain approx. 1 liter of ATF. This immediately reduced the cost of production at the expense of the transmission resource. Such transmissions cover 200 thousand kilometers with some problems. But at the same time advantages of this transmission are very attractive (high level of efficiency (up to 97%) and dynamics).

Repair and typical problems of DQ200

These transmissions are quite complex for repair, therefore replacement is more preferable option.

The most common problems are related to all new elements:

- The dual-clutch gets worn out early or unevenly in case of an aggressive driving style.

- The new electric oil pump breaks too early and frequently and operates in an abnormal fashion.

- Typical issues with operation of sensors.

- High oil pressure in Mechatronics units push out the oil with fatal consequences for the trasmission.

As a result, automakers had to modify the transmission and some separate units each 2-3 years, investing more and more financial resources in making the transmission more sophisticated and expensive and hope that the project DSG will pay off before releasing of 1 million transmissions. The most common problem that occurs in these transmissions (except clutches vibrations): damage of the shifting fork Reverse\6 (including bearing parts).

There are also different defects successfully fixed in services specialized in repairing DSG with a dry clutch. The repair process related to components of this transmission is quite complicated and therefore this option doesn’t have much support among car owners, especially when the engine resource comes to an end.
