Welcome aboard and congrats! I am loving my TDI, the mileage truly cant be beat and mine just continues to improve since i have been really focused on the lubricants and fuel additives and general maintenance
I apologize in advance for the lengthy post, I was feeling "chatty" LOL
Regarding the filter, I have purchased mine through Napa 2 of the times and then ordered 1 from an online ebay vendor the other time, so i havent really found a super deal on it, but since i was changing it multiple times, I bought a cheaper filter cus i knew it would only be in there a short time. The filter I finally left in for a full OCI was around $23 if i remember right and i believe I ordered it through Advance Auto Parts. Although after handling multiple brands of this filter I can tell you they were all identical. The paper looks like it might be just slightly stronger then toilet paper and if you run your fingernail down it, it kind of tears apart. Really odd I thought, but figured they knew what they were doing.
One thing I started doing that I really like now and do it with all the cartridge style filters (oil and trans) is presoak them in fluid before installing them. I actually got a 1 quart plastic paint bucket with lid for each type of filter and put just enough fluid or atf in it to submerge the filter and leave it for hours or even overnight if i think of it before changing it (with lid on of course to make sure dust does not get in).
I havent used a hose for mine, I actually found a long skinny plastic transmission funnel that fits perfectly into the little hole in the middle of the cartridge housing that holds about a qaurt of fluid. Then I tied it with a small bungy or wire to the hood so it stayed there without me having to hold it. The fluid takes forever to drain down into the transmission, so I fill it with about a qaurt of fluid and then go tinker elsewhere in the shop for 5 or 10 minutes at a time and just check it and keep the funnel topped off. I have thought about trying to pump it in some how, but figured it only takes about an hour this way start to finish including taking the air intake ductwork and cartridge housing off, plus I probably wont do it again for a year or 2 at least, so no biggie.
Then once fluid is all in, just pop in the presoaked filter and screw on the cartridge housing. I have been able to do mine without removing the battery by using a wobbly extension on my ratchet, but it is a little tight and certainly would be easier by removing the battery and battery tray if thats more your style. ( since i plan to try and get 500k+ out of this car, I have actually considered taking the battery tray out and cutting an inch or so off that back corner of the tray to make the trans changes easier, since that is 9 or 10 more trans fluid flushes ahead of me at least if all goes well, but most peeps dont like hacking stuff up, so that is definitely a little more aggressive.)
Anyways, I hope this helps in some way. I have really enjoyed working on this little car. Its so over engineered in silly ways that at first I felt like you needed a mechanical engineering degree just to change the oils LOL. But once you get the right tools its basically the same as changing the oil on any old gasoline car. I have cut a small hole in the plastic drivetrain cover thingy on the bottom of the car right below the oil drain plug, so I can change the oil without having to take any of that cowling off anymore and that has been a real time saver. And since I never drive on dirt roads, I have no worries of dirt or debris getting up in there and making it dirty, but again that is more of a personal thing and I know most peeps would not want to cut that stuff up.
Switching to 60 series tires versus the 55 series sidewalls that came with it just to get a little taller final gearing and with some crafty lubricant tricks and consistent use of good fuel and additives, I am now consistently getting 55+ mpg at 80 mph on the freeway trips and could not be happier. Car just seems to run better and smoother all the time, so I am pleased that the previous owners abuse and neglect has not caused permanent damage to the vehicle.
Bottom line - if anyone has any doubts about this DCT fluid from Valvoline, im at 13,000 miles since switching and am fully convinced the 1-2 and 2-3 shifts are smoother around town while the freeway shifts are now completely seamless. Also I just recently found a place selling a 6 pack of it online for less then $40 shipped, which might be a black friday price, so not sure it will stick around, but can save you a little money as well.
Thats all - off to work again
