General information about the 6-speed DSG transmission «02E»

6-speed DSG 02E is available on both FWD and AWD models (see specs). The DSG identification code is on the vehicle data sticker (see Introduction). The DSG itself is also marked with its identification code (HLH in Figure 10.1a), Date of issue (130804 = August 13, 2004), factory code (14), release time (06:32) and serial number (0011). Some transmissions have additional identification data in the locations shown in illustration 10.1b. To see them, it is necessary to remove the air cleaner, the battery with its pallet, unload the power unit supports and remove the console of the left support (see illustration 10.1c).








The main feature of the DSG is the presence of two parallel clutches, which allows two gears to be selected at once (only one gear included). Therefore, when shifting gears, time is spent only disengaging one clutch and engaging the other. Clutch shift points overlap during gear shifts, allowing acceleration with virtually no interruption in power flow, saving between 4 and 8% fuel. Interruption in power flow is a major disadvantage of traditional manual transmissions, automatic transmissions and manual CVTs.

The main details of the DSG are shown in illustration 10.2.




Unlike DSG "OAM", in DSG "02E" two multi-plate clutches in an oil bath are used. outdoor (big) clutch "K1" is responsible for the inclusion of odd gears, and the internal (small) clutch "K2" responsible for the inclusion of even gears.

Maintaining the correct level of fluids in the transmission is essential to the proper operation of the transmission. In DSG "02E" uses a common working fluid circuit for the mechanical area and for the hydraulic control unit "Mechatronic". Checking the fluid level of the 6-speed DSG is done when replacing it (see Section 21 of Chapter 1).

A 6-speed DSG fluid and filter change is required every 60,000 km.

Description of transmission control and its modes is given in Chapter "Controls and methods of operation". Gear shifting is carried out by means of hydraulic activation, with electronic control.

To repair the transmission, a lot of special tools are required, so the disassembly and assembly of the transmission and its components should be entrusted to service stations with the appropriate equipment.
