Transmission Temperature Sensor/Switch: Service and Repair

Transmission Input Speed Sensor G182 and Clutch Oil Temperature Sensor G509

Both sensors are a single component and can only be replaced together. They are coated with oil in the transmission near the Direct Shift Gearbox (DSG(R)) clutch. Before removing, the Mechatronic unit must be removed.

Often, the sensor wire is pulled. It will get damaged. If the wire was pulled, the sensor must be replaced.
