To replace the magnet of the Audi A6 C7 and A4 B8 phase shifter, you will need to unscrew 3 Torx T30 bolts, the VAG manufacturer advises changing these bolts as they are disposable.
The tightening torque of the bolts is 9 Nm.
The reason for replacing the magnet is the presence of oil in the connector, oil fogging around the magnet.
