Your customers may not realize what maintenance the six-speed DSG DQ250 transmission in their Volkswagen or Audi vehicle requires. Besides the transmission maintenance recommended by the vehicle manufacturer, including oil and filter changes every five years or after 35,000 miles, there are also some weak points that frequently force vehicles with this transmission into the repair facility.
One of these problems is leakage and oil loss at the lower part of the transmission oil pan, caused partially by a defective oil pan gasket, but also by corrosion on the oil pan itself. Another issue is defective mechatronic units, which can lead to massive shifting problems and even total transmission failure. In this case, the vehicle manufacturer only offers to replace the complete and very expensive mechatronic unit. However, it is often sufficient to replace the control board.
