Note. Repair work for the vane pump is not provided. In the event of complaints, the cause must be determined by means of a pressure test and a leak test. If there is a malfunction, the vane pump should be replaced. If there is no working fluid in the reservoir, it is necessary to check the tightness of the steering. If there is no seal near the line connections, first check the lines/line connections for leaks, tighten if necessary and wipe dry. The vane pump is supplied unprimed. Therefore, before installation, be sure to fill the pump with hydraulic fluid and turn it by hand. Otherwise, operating noise or damage to the vane pump may occur.

Removal
Repair work for the vane pump is not provided. In the event of complaints, the cause must be determined by means of a pressure test and a leak test. If there is a malfunction, the vane pump should be replaced. If there is no working fluid in the reservoir, it is necessary to check the tightness of the steering. If there is no seal near the line connections, first check the lines/line connections for leaks, tighten if necessary and wipe dry. The vane pump is supplied unprimed. Therefore, before installation, be sure to fill the pump with hydraulic fluid and turn it by hand. Otherwise, operating noise or damage to the vane pump may occur. Place the vehicle on a lift. Remove engine cover upwards -arrows-.
Pump out hydraulic fluid from the reservoir using a waste oil collection and pumping device. Clamp suction hose -1- and return hose -2- using hose clamps up to 025 mm -3094-.
Do not attach hose clamps up to 025 mm -3094- to the return hose -2- near the check valve. Otherwise, the check valve may be damaged. The non-return valve is located in the return hose -2- between the clamps -arrows-. Remove sound insulation. Unscrew the nuts -1- and remove the extension. coolant tank -2- with connected lines. Unlock the plug connector for the extension. coolant reservoir -2 and disconnect.
Before removing the poly V-belt, note the direction of rotation. Changing the direction of rotation of a used belt can lead to its destruction. When installing the poly V-belt, ensure that it is positioned correctly on the pulleys. Turn the tensioner to release the tension on the poly V-belt in the direction of -arrow-. Remove the poly V-belt from the vane pump pulley only. Loosen the tie and remove the tool.
Mark the position of the pulley in relation to the hub. To do this, mark -arrow-.
When replacing a vane pump, transfer the markings on the hub from the old pump to the new one. It is impossible to determine in what position the pulley holes are located relative to the holes in the hub during installation due to limited space. Unscrew bolts -arrows-. To hold, use the 2-hole wrench -3212-. Remove the vane pump belt pulley. Place a tray under the vane pump.
If present, carefully cut cable clamp -1- of wiring harness -2-. Remove the clamp -4- from the suction hose -3-. Remove suction hose -3-.
If the pressure line is additionally attached to the air conditioning compressor, remove bolt -C- from bracket -D- of the air conditioning compressor.
Unscrew the union nut -1 - and remove the pressure line from the vane pump. Unlock and disconnect plug connector -2-. Close the connections of the vane pump and the line with clean plugs.
Unscrew the vane pump fastenings from the bracket. To do this, unscrew bolts -1- at the front and bolts -2- at the rear. The bolt -2- in the bracket is not visible; in the figure it is shown in the unscrewed position.
Remove the vane pump.
Installation
Install in reverse order. In this case, the following must be taken into account: to install the vane pump, it is necessary to slightly move the bushing -2- in the bracket back. Ignore positions -1 and 3-.
Replace seals and seals. rings. Before installing a new vane pump, fill the suction side with hydraulic oil and turn it by hand until the oil comes out on the pressure side. Secure all hose connections with new clamps. It is not possible to tighten the clamp -2- using hose clamp pliers when the vane pump is installed due to limited space. Before installing the vane pump, put on the suction hose -1 - and align the mark "R"-3- with mark-5- on the vane pump. Secure the suction hose -1 - with a new clamp -2-. If installed, - secure the wiring harness with a new cable binder -4- to the fitting.
Pay attention to the installation size of the clamp. Dimension -a- should be 4 mm. Insert the vane pump into the bracket.
First tighten the front bolts -1-.
Then tighten the rear bolt -2-.
Tighten bolts -1-AND-2-.
Make sure the suction hose is properly fixed (twisting/kinks). Turn the hub by hand until oil comes out from the pressure side. Press the pressure line into the vane pump as far as it will go. Then screw in the union nut -1-. Install plug connection -2-.
Tighten the union nut using the open-end union socket SW 17 -VAG 1331/10- as shown in the illustration.
