What Causes DSG Automatic Transmission Failures?
1 Answers
DSG automatic transmission failures are primarily caused by malfunctions in the transmission's mechatronic control unit. The DSG combines the flexibility of a manual transmission with the comfort of an automatic transmission, while also providing uninterrupted power output, which is fundamentally different from two automatically controlled clutches. The DSG is essentially composed of several major components: two basic 3-shaft 7-speed forward mechanical gearboxes, an electro-hydraulic clutch mechanism containing two sets of multi-plate clutch discs, and a gearbox ECU. Unlike conventional dual-shaft gearboxes or single input shaft systems, the DSG gearbox not only features dual clutches but also incorporates a coaxial dual input shaft system, with the 7 forward gears distributed on the driven shafts on each side.
