Renewing internal oil pipe — AUDI

Special tools and workshop equipment required

Installing tool 3321

Installing tool T40006

Notes:

Always fit new oil pipe after removing.
As of gearbox No. 13 665, the gearbox housing has a notch -arrows- in each hole for the oil pipe. When a new oil pipe is installed, this gearbox is always fitted with O-rings, without regard to which type of oil pipe was fitted previously.
The oil pipe may only be installed using installing tool 3321(for oil pipe without O-ring) or installation tool T40006(for oil pipe with O-ring).
If the oil pipe is installed without using the relevant special tool, the result may be leaks caused by bending the oil pipe.
A bad fit or defective O-rings on the internal oil pipe will allow ATF to leak into differential, which will overflow and cause oil to drip out of differential breather.
