t	Torque wrench -V.A.G 1332-

t  Repairs must not be performed on the motor/pump unit t  If problems are reported, determine the cause by means of a function test, pressure test, leakage test and self-diagnosis. t  If a fault is found, the motor/pump unit must be renewed. t  Residual quantities of hydraulic fluid remain in the motor/pump unit and in the return and pressure lines after extracting. t  Do not re-use hydraulic fluid which has been drained off. t  Pressure and return lines must not be clamped off with hose clamps, e.g. -3094-, or other tools. Clamping can cause damage to the pressure line or return line. t  When bending or repositioning the pressure line or return line, make sure that the bending radius is not less than 100 mm to prevent damaging the lines. Removing –  Disconnect earth strap of battery with ignition switched off → Electrical system; Rep. Gr.27. Vehicles with air filter on left in engine compartment –  Remove battery and battery tray → Electrical system; Rep. Gr.27. Continuation for all vehicles

–  Unscrew cap -1- from motor/pump unit -2-. –  Draw off as much hydraulic fluid as possible from motor/pump unit using a suction bottle. –  Remove front left wheel. –  Remove front left wheel housing liner → General body repairs, exterior; Rep. Gr.66. –  Remove noise insulation.

–  Open spacer -arrow A-. –  Remove pressure and return line -1- and -2- from spacer. –  Take out line -3- for power steering sensor -G250- from spacer. Vehicles with air conditioning

–  Remove radiator fan control unit -J293--1- from longitudinal member -arrows-. Continuation for all vehicles

–  Open spring-type clip on return line -1- and pull off return line from fitting on motor/pump unit. –  Unscrew pressure line -2- from motor/pump unit -3-. –  Close off threaded bore on motor/pump unit e.g. with plastic sealing plug. –  Close off pressure line, return line and connection piece on motor/pump unit with a plastic bag and adhesive tape. –  Unscrew and remove bolts -arrows - and slightly lower motor/pump unit with bracket.

–  Pull connectors -1-, -2- and -3- off motor/pump unit -4-. –  Remove motor/pump unit with bracket. Installing t  Use new sealing rings for hose/line connections. t  Ensure sealing surfaces are clean. Install in reverse order. Vehicles with air filter on left in engine compartment –  Install battery and battery holder → Electrical system; Rep. Gr.27. Continuation for all vehicles –  Connect earth strap of battery → Electrical system; Rep. Gr.27. –  Fill up with fresh hydraulic fluid - use a hose (approx. 400 … 500 mm long) and a funnel to do this. –  Use hydraulic fluid -G 004 000 M2-. –  Bleed steering system → Chapter. –  Check hydraulic fluid level → Chapter. –  Install front left wheel and tighten bolts or nuts → Chapter.
