Exploded view for vehicles with 6-cyl. 5-valve turbo engine (bi-turbo) — AUDI

General

Vane pump servicing work is not envisaged. In the event of complaints, perform pressure test and leak test to establish the cause. Replace vane pump if fault is found.

With the exception of extension of the hydraulic pipes from left to right at the steering box, the fluid circuit of RHD vehicles corresponds to that of the LHD version.

Always check steering system for leaks in the event of a lack of fluid in the reservoir.
If a leak is found in the area of the pipe connections, start by checking pipes/pipe connections for leaks, re-tighten if necessary and wipe dry.
Replacement pumps have no fluid fill. Prior to installation they are therefore to be filled with hydraulic fluid G 002 000 and cranked by hand to avoid the possibility of noise whilst driving or pump damage.
Type: Hydraulic fluid G 002 000
