Removing and installing power-assisted steering sensor -G250- (TRW or KOYO) - RHD version Special tools and workshop equipment required t  Vehicle system tester -V.A.G 1552- or vehicle diagnosis, measurement and information system -VAS 505x- Removing: –  Raise vehicle. –  Remove right front wheel. –  Remove the sound dampening system → Body Work; Rep. gr.50. –  Remove the front right wheelhouse liner → Body Work; Rep. gr.66.   Note

The followings steps for removing the line do not need to be carried out on vehicles with a power steering of TRW and a power-assisted steering sensor -G250- (-2-) with an adapter cable -4-.

–  Unhook line of the power-assisted steering sensor -G250- from the line holders -arrows-. The line of the power-assisted steering sensor -G250- is attached with 3 line holders and a spacer holder.

–  Open spacer holder -arrow-. –  Remove line -1- power-assisted steering sensor/engine pump aggregate.

–  Disconnect plug -1- from the engine pump aggregate with noise encapsulation -2-. The engine pump aggregate of TRW is illustrated in the figure. The plug assignment for the engine pump aggregate of KOYO is analogous to the version of TRW.

Inspecting the power-assisted steering sensor -G250- (TRW) for power-assisted steering sensor -G250- with fixed connecting line (TRW): –  Release screws -1-. –  Pull the power-assisted steering sensor -G250 - (-2-) with seal -3- out of the power-steering gear.

for power-assisted steering sensor -G250- with adapter cable (TRW): –  Disconnect adapter cable -4- from power-assisted steering sensor -G250- (-2-). –  Release screws -1-. –  Pull the power-assisted steering sensor -G250 - (-2-) with seal -3- out of the power-steering gear.

The power-steering sensor -G250- (KOYO) –  Release screw -1-. –  Pull the power-assisted steering sensor -G250 - (-2-) with seal -3- out of the power-steering gear. Installing: Installation is performed in the reverse order, pay attention to the following points: –  Use new seal for power-assisted steering sensor -G250-! –  Connect battery → Electrical System; Rep. gr.27. –  Perform automatic test sequence → Chapter using the vehicle system tester -V.A.G 1552- or the vehicle system test → Vehicle diagnostic, testing and information system VAS 5051 using the vehicle diagnosis, measurement and information system -VAS 505x-. If a fault is stored in the fault memory: –  Remove fault → Chapter. –  Erasing fault memory → Chapter.
