General information about the 6-speed DSG transmission «02E» (Skoda Superb B6)

the 6-speed DSG 02E transmission is installed on both FWD and AWD models (see Specifications). The DSG identification code is indicated on the vehicle data sticker (see Introduction). The DSG itself also has its identification code (HLH in Illustration 10.1a), production date (130804 = 13 August 2004), factory code (14), production time (06:32) and serial number (0011). On some transmissions, additional identification data is located in the locations shown in Illustration 10.1b. To view them, it is necessary to remove the air cleaner, battery and its tray, unload the powertrain mounts and remove the left mount console (see illustration 10.1c).







The main feature of DSG is the presence of two parallel clutches, which allows two gears to be selected at once (only one gear is engaged). Therefore, when shifting gears, time is spent only on disengaging one clutch and engaging the other. The moments of clutch switching during gear shifting overlap, which makes it possible to accelerate with virtually no interruption of the power flow, allowing fuel savings of 4 to 8%. Interruption of the power flow is the main disadvantage of traditional manual transmissions, automatic transmissions and continuously variable transmissions operating in manual mode.



The main parts of the DSG are shown in Figure 10.2.



Unlike the DSG "OAM", the DSG "02E" uses two multi-plate clutches in an oil bath. The outer (large) clutch "K1" is responsible for engaging odd gears, and the inner (small) clutch "K2" is responsible for engaging even gears.

For the correct operation of the transmission, it is extremely important to maintain the correct level of fluids in it. The DSG "02E" uses a common circuit of working fluid for the mechanics area and for the hydraulic control unit "Mechatronic". The fluid level of the 6-speed DSG is checked when it is replaced (see Section 21 Chapter 1).

Replacement of the working fluid and filter of the 6-speed DSG is required every 60,000 km.



The description of the transmission control and its modes is given in the Chapter "Controls and operating techniques". Gear shifting is carried out by means of hydraulic activation, with electronic control.

Repairing a transmission requires a lot of special equipment, so disassembling and assembling the transmission and its components should be entrusted to service station specialists who have the appropriate equipment.
