How do you replace a wiper washer pump on Audi A4?

Answer 1

I just did this however you need to make sure something as simple as the fuse is not blown. I was told that if the wipers still functioned that the system fuse (usually a 30A fuse) was not blown. The wipers did work and the 30A fuse was good so decided it was the washer pump. Here is step by step to get at washer.

1. Remove drivers side front wheel

2. Remove inside fender wheel well covering (about 6-8) screws

3. Upon removing cover you will note to left of wheel the plastic washer reservoir. Located behind this reservoir are the pumps.

4. Unscrew reservoir bolts and pull reservoir loose from grommet at top of fill container. Also at this time you can now disconnect the water level sensor plug that plugs in to the left side of the reservoir

5. Pull reservoir out and you can now locate pumps. If the pumps are bad, this is an easy fix of disconnecting the electrical connects, disconnecting the water lines and pulling th pump out of the reservoir fitting.

6. Replace new motors and reassemble in reverse order.

Note. In the Audi A4 that I worked on, there was an additional fuse that went to these pumps, called the Intelligent Module (20A). Check this prior to assuming pump is bad.

I can personally attest to the value of checking the Intelligent Module fuse. After freaking out 'cause daughter's car wouldn't wash, I went in search of a washer pump - pretty easily found by the way, and about $35.00. When daughter got home, I checked the wiper fuse first, which was good. Then I checked the Intelligent Module fuse -low and behold it was popped. Probably by the headlight washers being iced over.

A switch of the fuse and we were pumping again. If you live in a climate where freezing temperatures occur check the Intelligent Module fuse first (#37 bottom row middle). Mine was blown possibly due to ice and or snow buildup on the headlight washers. My windshield wipers worked but the spray wasn't. A blown fuse is most likely the problem and cheapest to resolve.
