Replace the O-rings, seals and gaskets.
After removing seal rings and seals, always inspect the contact surfaces at housing or shaft for burrs resulting from removal, or for other signs of damage.
Before installing the seal rings, lightly oil the outer circumference and fill the space between the sealing lips -arrow- halfway with GreaseG 052 128 A1.
The open side of the seals point toward the fluid to be sealed in.
Use DSG^® transmission fluid only. Other lubricants cause malfunctions.
Check the oil level in the Haldex clutch after replacing gaskets, O-rings and seals.
