The plastic cowl that fits under the windshield wipers needs to be replaced. I have the new piece but to install it I have to remove the whole wiper. There is a little plastic cover over a 15 mm nut, which I have removed but the wiper arm still doesn't seem to budge. Is there something else holding it on or do I just need to force it off??

The wiper motor on a Volkswagen is an electric motor connected through a drive linkage to the wiper arms. Windshield wipers are an integral feature for operating a motor vehicle safely. If your wipers are not functioning, or seem to lack the speed or power they used to have, the wiper motor should be removed and replaced immediately .
The wiper motor on a Volkswagen is located directly underneath the plastic cowl cover. The cowl cover is located directly below the windshield.
Begin by removing the wiper arms by prying off the covers at the base of the arms and removing the nuts that secure the arms to the drive shafts. Label the passenger and driver arms so they can be installed in the same positions. They are not interchangeable. Remove the rubber hood to cowl weather seal. Unscrew the plastic fasteners from the driver's side of the cowl cover, then remove this half of the cover. Remove the fasteners from the passenger's side cowl cover and remove this half of the cover. Disconnect the windshield wiper motor wiring harness by separating the plastic wiring connector. Remove the three bolts that secure the wiper motor to the vehicle's body. Pull the motor slightly away from the body, then remove the nut that connects the motor shaft to wiper linkage. Remove the motor.
Place the new wiper motor into position in the cowl and reconnect it to the wiper arm linkage. Then reinstall the three retaining bolts. Reconnect the plastic wiring connector to the wiper motor wiring harness. Place the cowl covers into position below the windshield and reinstall the plastic fasteners that retain them. Reinstall the rubber hood to the cowl weather seal. Reinstall the wiper arms in the same position you removed them from, along with the wiper arm retaining nuts and lower wiper arm covers. Turn the windshield wipers on and test for proper operation. If the wiper blades slap against the bodywork surrounding the windshield, loosen the nuts that connect the wiper arms to the shafts and adjust.
Your wiper transmission is bad or disconnected. The part with the arms that are moving under the windshield cowling is called a wiper transmission. The main connection to these arms is a pin on the wiper motor which has a clip. The cowling is the area directly under the windshield. You may be able to unscrew the cowling and remove it to access the shaft arms on the wiper transmission.
You may need to remove the wiper motor to get at the clip on the motor. Then each arm is mounted to the base of the cowling. These are the stubs which the wiper arms attach to. Usually the shaft arms are a permanent part of the piece which fits over the motor. But is worth a look at what broke to see how it used to be attached.
If the transmission arms were in a pressed-on fitting, you will either have to replace it or improvise a new connection. The connection will have to be secure, yet not drag on the wiper, and not make noise. That kinda makes a new part or Salvage yard part your options.
By going to a Salvage yard first, you will learn how the part comes off. Gather extra screws for the ones you may drop reinstalling the part. And if you break something on the Salvage car, you will know better when you work on yours.

(the black plastic piece at the bottom of the windshield, under the wiper arms) remove the wiper arms, remove the cowl, it is held on with aprrox 8 phillips screws.

With the wipers at rest, mark their positions on the windshield with a piece of tape or a grease pencil. Remove the small cap on the shaft end of the windshield wipers, just pry it off with a small screwdriver. Then wiggle and pull the wiper arms until they come loose. There are some small clips on the forward edge of the plastic cowl, just pull them forward. Then there are 2 TORX screws, one at each end of the cowl under that rubber flap. Now remove the cowl and set it somewhere you won't step on it. Unplug the electrical connector from the wiper motor and disconnect the linkage. Then you can unbolt the motor and remove it.

The cabin air filter is located directly underneath the cowling at the base of the windshield on the passenger side of the car. To access the cabin air filter, you will need to remove the cowling. First, open and lift the hood. Second, locate two plastic pins securing the plastic cowling at the base of the front windshield, on the passenger side. One is located under the wiper blade, near its base. Use a small screwdriver or similar tool to carefully lift/pop up two plastic pins securing the cowling, taking care not to damage the plastic pins. (You want to lift the pins, and not the anchors that look like washers beneath the heads of the pins. Carefully pull the plastic pins and their plastic anchors (once you pull the pin up, you can safely remove the anchor). Take caution not to damage the pins and anchors as you will need them to rescure the cowling when you are finished replacing the cabin air filter. Before you remove the cowling, carefully pull back the rubber gasket and windshield washer fluid tubing at the base of the cowling. You can now safely remove the cowling, and you will see the cabin air filter below. Remove the old cabin air filter and replace it with a new filter. Reverse this process to reinstall the cowling, gasket, and pins once you have replaced the filter.
