You mean fill the washer tank? Open hood. Look to the left of the engine toward the front. There is a tank with a blue cap. Open cap, remove strainer. Open washer fluid jug, pour it in. Replace strainer, snap down cap. Easy peasy, lemon squeezy.
The windshield washer system
They are headlight washers. When the headlghts are on pull the windshield washer switch. It activates both windshield and headlight washers.

Low windshield washer fluid most likely. Look in your owner's manual.
With a screwdriver
The 1996-2001 Audi A4 has the most common hook-end wiper arms. See sources and related links below for installation videos. Also, purchase the replacement blades first and there will be additional instructions/illustrations on the replacement packages. Locate and press the tab or button where the wiper blade is inserted into the hook of the wiper arm and pull wiper blade out of hook. You may have to rotate and flex the blade to make enough clearance for the hook to pass through.
You need a wiper arm removal tool. Look on ebay.
It is not a motor- it is a pump. Located at the bottom of the washer tank.
It is an option but most of the late models that are built for North America have it as a standard option. Look for a switch on the lower edge of the windshield wiper arm that turns the display on and off.
Depends On Year - I looked up 2001 in the related link below, however you can change the year to the year of your A4 and look them up.
