Oil Change DIY discrepancy
I bought the Mityvac 7201 fluid extractor. I have a 2.0 C7, so the oil filter is easily accessible and I saw that I could siphon out the oil from the dipstick tube so I did it myself.
The thing is, the Mityvac only got out ~2.3quarts of oil after air started gurgling (oil temp was ~140F). My MMI had given me the Add oil warning, and in the past when I have topped it off it takes 1 full quart of oil to go from the low level indicator to full. So, doing the math, 2.3quarts extracted, plus 1 quart that I was low on already, that's 3.3quarts. I thought the 2.0 had an oil capacity of 4.9quarts? Where is the rest? I made sure to insert the Mityvac tube all the way to the bottom of the dipstick tube.
Even more, I was so suspicious the first time I extracted it, that I decided to put that oil back into the engine and move the car to a more flat surface, since I it was sitting in a slight incline. No difference, same 2.3quarts came out. At that point I decided to continue and added 3.3quarts of fresh oil, changed the filter, read the oil level from the MMI and it said it was full.
I went into Amazon and ordered a dipstick, should arrive Monday. Not sure if the MMI reading is off, and it's telling me the level is full when it's missing ~1.5quarts, or could it be that the Mityvac didn't get it all out? Any thoughts are appreciated.

When I would change my 2.0T with an oil extractor, I found that I had to be sure that I pushed the tube down all the way a couple times or I wouldn't get all the oil. Then, I would reprime it a few times and give it plenty of time to drain, even after it gurgled. It won't get it all, but it should definitely get almost all of it. I don't have my 2.0t anymore and will be changing a 3.0T from the top instead pretty soon, so I'm interested to see how that goes. The dipstick is important though, more to make sure that you don't overfill it than anything else. I've bought mine from ECSTUNING.
Anyone know if the dipstick is the same on the 2011 and 2016? If so, I can change the oil on my 2016 when my kid's 2011 is in town.

I've done three changes on my 2011 3.0 and it was a breeze. I had no problem finding the bottom of the sump and siphoning out the 7+ quarts. I haven't done my 2016 Audi that doesn't have a dip stick. That will be a little tricky making sure I don't overfill. I'll probably start out seeing how much I extracted with the markings on the Mityvac and then putting that much back in and then checking the MMI.

PS: the dipstick part number for 2.0T C7 is 06J-115-611E. Getting mine tomorrow, it should answer a lot of questions.

Update: The dipstick arrived today. It shows the oil level right at the MAX line, same information I’m getting from the MMI. The question now is how did I miss the 1.5 quart remaining, even after doing the extraction twice.
Looking at the mityvac tube it’s got an angled opening at the bottom. I may need to cut it flat, so that air does not enter and it can really sit flat at the bottom and maybe fixes the issue.
Nevertheless I now have to live with doing an oil change and ending with a mixture of 1/3 dirty and 2/3 of new oil. Definitely not very happy about it...

Don't push on the tube too hard after it bottoms out. One guy did and it kinked. He had to drop the oil pan to extract it.
