0B5A Automatic Transmission
Electrical and Electronic Components and Component Locations
Data Link Connector (DLC)
• Location: The Data Link Connector (DLC), for example, for the Vehicle Diagnosis, Testing and Information System (VAS 5051B) is located in the driver's side footwell.
Direct Shift Gearbox (DSG) Mechatronic (J743), valves, sensor and transmission input RPM sensor
• Location: Direct Shift Gearbox (DSG) Mechatronic (J743) is bolted on to transmission housing on the bottom and covered by transmission oil pan.
• The mechatronic unit incorporates the hydraulic control, the Transmission Control Module (TCM), the Multi-Function Transmission Range (TR) Switch and the sensors and actuators as a complete synchronized unit.
• All components mentioned are tested by On Board Diagnostics (OBD).
• The complete mechatronic unit must be replaced if there is a fault.
