If you live in a place like sunny Southern California you may go a long enough period of time without using your windshield washer fluid that you forget you have a reservoir. If you live in the north east there is a very good chance that you have a much more familiar relationship with the reservoir. Either way the reservoir is made of plastic and goes through heat and cold cycles and will eventually wear out. Most reservoirs will start to fail by splitting along the seams and develop micro cracks. One way to prolong the life of the reservoir and the washing system in general is to make sure that you have the proper mixture of water to washer. If you live somewhere where the temperatures get below freezing you definitely want to make sure that you do not just have water in the washing system.

Proper windshield washing fluid not only has mild cleaning properties it also contains an ingredient to keep the fluid from freezing. If the fluid freezes in the system it will expand to the point that it can damage both the lines, pumps and reservoirs. Make sure you always have the correct fluid in your system.

The windshield washer reservoir on the Audi A4's are made up of two separate reservoirs. The upper reservoir is removed from the vehicle from the engine bay while the lower reservoir (where the pumps are located) is serviced and replaced from the front left wheel well. Over time, the windshield washer reservoir tends to break and leak and the pumps tend to stop functioning. A leaking reservoir is easy to diagnose but make sure to check the fuses for the pumps before just replacing them.

You will need to remove the front left wheel well liner to work on the pumps and lower reservoir; please see our article on wheel well liner removal for further assistance.

Begin by suctioning out as much of the fluid as possible. While you can remove the pump assembly while the reservoir is in the car, it is easier to do if you remove the whole assembly. Once you remove the pump whatever fluid remaining in the reservoir will flow out through the pump grommet.

The upper section of the reservoir is located on the left side of the engine compartment (red arrow).

The upper section of the reservoir is located on the left side of the engine compartment (red arrow).

The lower section of the reservoir is located behind the front left wheel well liner (red arrow).
Figure 2

The lower section of the reservoir is located behind the front left wheel well liner (red arrow). This section of the reservoir contains the pumps. You will need to remove the wheel liner to get access to the reservoir.

Begin by suctioning out as much fluid as you can.
Figure 3

Begin by suctioning out as much fluid as you can. You can suction out the upper tank first and then the lower tank after you have removed the upper tank.

With the fluid removed, remove the 7mm nut holding the section of the tank towards the windshield (red arrow).

With the fluid removed, remove the 7mm nut holding the section of the tank towards the windshield (red arrow).

Use a 10mm socket and remove the bolt holding the tank to the fender rail (red arrow).

Use a 10mm socket and remove the bolt holding the tank to the fender rail (red arrow).

You can now pull the tank up and out from the vehicle.
Figure 6

You can now pull the tank up and out from the vehicle. The upper tank has a rubber grommet in its base (red arrow) that sits around the tube in the lower tank (yellow arrow). Make sure to disconnect the overflow hose from the upper tank to lower before removing completely (green arrow).

With the wheel liner removed you can see the tank.
Figure 7

With the wheel liner removed you can see the tank. It is held in place by three 10mm bolts (red arrows). It is a good idea to disconnect the electrical connector (yellow arrow) on the side of the tank before removing the bolts.

This connection can get very dirty and damaged and may need both hands to get it off without breaking (red arrow).
Figure 8

This connection can get very dirty and damaged and may need both hands to get it off without breaking (red arrow). With the bolts still attached to the vehicle this will help hold the reservoir in place while removing. Once removed remove the three 10mm bolts.

Tilt the reservoir back, lower it slightly and remove the pumps from the reservoir (they just pull straight out from the rubber grommets they sit in).
Figure 9

Tilt the reservoir back, lower it slightly and remove the pumps from the reservoir (they just pull straight out from the rubber grommets they sit in). With the pumps removed you can remove the reservoir from the vehicle.

You can now easily service, replace or repair the pumps, electrical connections or hoses (red arrows).
Figure 10

You can now easily service, replace or repair the pumps, electrical connections or hoses (red arrows). Installation is the reverse of removal. Do not forget to refill the reservoir and check for leaks.
