4.3 ATF Pump, Deactivating and Draining
the Hydraulic Pump Reservoir
WARNING
The system is under pressure.
The ATF transmission “7 speed S tronic Transmission 0CK” is
equipped with an electronic ATF pump and a hydraulic pres‐
sure 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 pres‐
sure reservoir is drained.
♦ When the system status is not clear, for example the
cause of a faulty transmission control module or transmis‐
sion 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- con‐
nector before removing the oil pan.
♦ Wear protective eyewear.
