Yeah. I did a top-fill using a nifty tool from Amazon. I drained using the exterior metal plug and let it stop. Then removed the inner plastic tube and let it drain all the way out. While that was goin I removed the battery and intake box, removed the filter and cleaned the inner threads as well as the filter housing. Applied clean fluid around the new seal and replaced in the channel it sits in. I then replaced the inner tube drain plug and stuck my funnel and tube tool directly into the hole where the filter rests and filled 1L at a time. Then replaced the exterior drain plug hand-tight and let the transmission get up to temperature. Car was fairly hot from driving earlier in the day still so it was pretty quick to drain and get back up to temp. Let it run and then removed the metal plug to drain excess and then torqued it back in with the fresh washer. Easy peasy!

I’ve done it twice with this. Yeah it’s slow but certainly not 4 hours. Hold it up, fill it up and let it drain in. I sort of ran my fingers down the sides of the tube a bit to help move the fluid slightly faster.
If you can DIY oil changes you can do them for $25-40 depending on if you buy in bulk/hit rebates. Mobil 0w-40 is VW approved, available at Walmart for cheap an gets Mobil rebates twice a year. 3 pack of VW filters can be had on amazon for $22ish. That’s 3 years of oil filters if you’re doing 10k a year. Sounds like you might do 20k. Still not bad on costs for those changes if you do the bulk buying, which would make sense for you to do.
It’s a super easy car to do a change on too. Invest in an extractor from eBay for $45-65 and it gets even easier.
DSG service is every 40k. Period. Don’t skimp. You can get a kit yourself on eBay for under $100. Plenty of DIY out there on golfmk7.com or YouTube. It’s not hard just takes a bit because the fluid is thick. Pentosin is the OE fluid. Check the wiki here, I think I linked it there. This is the funnel you need: Hopkins 10704 FloTool Spill Saver Measu-Funnel https://www.amazon.com/dp/B000EH4V0Y/ref=cm_sw_r_cp_api_dPoFBb6XRQCHV
Wiki also has maintenance schedule which should be same/similar for MK7.5. You can double check against your owners manual too. I do filters, plugs, and brake fluid/coolant early.
Emergency fund you should just build regardless of what car you have. Have it and you won’t need to worry about how much you have in it.
A lot of brands don't have a clear section. I have one of these: Amazon, Measure Funnel
Did my DSG Service about a month ago for about $160. Took me a while but I saved a lot of money. I also took the battery and battery tray out and filled it through the too hole, rather than the bottom gravity fill. Very easy. Just time consuming.

DIY should be pretty easy, there are videos online. The kit is available on Rockauto.com for cheap ($86 shipped for me), too. https://www.rockauto.com/en/moreinfo.php?pk=7668792&cc=1505266&jsn=390
You'll also want a Hopkins 10704 FloTool if you are doing the top fill method.
