ATF Pump, Deactivating And Draining The Hydraulic Pump Reservoir
WARNING: This page is about a different car, the 2024 Audi A4 allroad. However, it is still accessible from the selected car via links, so may be relevant.
Special tools and workshop equipment required
- Vehicle Diagnostic Tester
CAUTION:
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.
- Release and disconnect the Transmission Control Module -J217- connector before removing the oil pan.
- Wear protective eyewear.
- Wear safety gloves.
