ATF Pump, Deactivating And Draining The Hydraulic Pump Reservoir
Special tools and workshop equipment required
- Vehicle Diagnostic Tester
WARNING:
The system is under pressure.
The "7-Speed Dual Clutch Transmission" is equipped with an electronic ATF pump and a hydraulic pressure reservoir.
The electronic ATF pump can start up at any time.
The ATF system also remains under pressure with the ignition switched off due to the hydraulic pressure reservoir.
- The electronic ATF pump must be deactivated every time before opening the transmission, and the hydraulic pressure reservoir is drained.
- When the system status is not clear, for example the cause of a faulty transmission control module or transmission is unknown, only loosen the mechatronic bolts to a minimal degree, so that the oil pressure in the pressure reservoir can decrease slowly.
- Disconnect the Transmission Control Module -J217- connector before removing the oil pan.
- Wear protective eyewear.
