I developed a severe leak in my windshield washer that was causing the tank to empty within 24 hours. The pumps appeared to be working, but i had to remove the tank to determine the cause. Turns out the internal seal of the windshield washer pump had failed and fluid was leaking out of the housing. In the process I documented the steps needed to remove the tank for your reference in the attached PDF. This is for a 2009 997.2 Carrera Base with the headlight washers. Hope this helps.

Finally got around to this and took some pics for future reference. The procedure is a bit different for the 92A than the 9PA, at least the 2013 model year. I suspect it is the same for the 2011 and 2012 model years as well. First, their is only one screw to remove, using a T2 Torex wrench. It in the front, middle of the panel. You need a panel pry tool or strong fingers to release the front catches that are still holding it in place. Slip the tool between the panel and the glove box at one end to get the snaps to release. The end at the firewall is held in place with two rubber fingers that slip into brackets near the firewall. Rotating the front of the panel down will get these to slip out. Once you have the panel off, you are confronted with an air duct that has to be removed in order to get to the filter box. There is a retaining catch near the passenger door that needs to be released first. Locate it with your fingers and pry one side open. It will slip off the post at that point. The other end is a slip fit, so wiggling will get to release. The cover for the cabin filter does not have a screw holding it in place. Instead there is a hollow square plastic retainer at the firewall side that slips over a post at that end. The passenger side has a U shaped retaining clip. You have to release this one first. Its very tight quarters at that end. I could not get my fingers in there to release the clip. I fashioned a tool out of an old hose clamp by bending one end into a tight U. I slipped this end into the gap shown, hooked it over the retaining clip, gave a tug and this end of the filter cover released. Simply slip the other end off of the post. The filter itself takes some squeezing and wiggling to remove. The filter is bigger than the opening, so you will need to get you fingers in there to compress it to get it started out of the opening. Installation is the reverse of removal. Again, you have to compress the filter somewhat to get it into the box. Once it is in there, it wont fall out. Don't forget to put the gray foam gasket back on the filter cover before you snap it in place. Slip the firewall end over the post and snap the other end over the retainer post. The air duct is next, wiggling the large end back in place and snapping the retaining clip back onto the mating post. The two fingers on the back of the bottom panel slip into the appropriate brackets and the snap the front in place. Replace the one screw and you are done. With practice and the appropriate tool to get the cover retaining clip to release, probably a 15-20 minute job max.
