Expect deep dives into complex modules like the ABS, airbag systems, seat memory functions, and the automatic convertible top mechanism.
Transmission and Drivetrain Specifications
The Tiptronic section provides detailed reference data for transmission actuation, gear control, and final drive assemblies. Torque values are laid out clearly. The ATF filler screw requires 80 Nm (59 ft-lbs), while the converter to drive plate needs 39 Nm (29 ft-lbs). Fluid capacities are exact: roughly 3.5 liters for a transmission oil change and 0.8 liters for the final drive. Fastening the hydraulic control unit requires a precise 8 Nm (6 ft-lbs).
Keep in mind that dropping a transmission or working with pressurized hydraulic control units involves heavy lifting and potential fluid hazards. Always use properly rated transmission jacks, wear proper eye protection, and adhere strictly to standard workshop safety protocols when applying these torque specifications.
This workshop manual provides the exact specifications authorized technicians use to maintain factory standards across the complete vehicle assembly.
