The TSB says
"Engine oil consumption too high, 2.0L TFSI (EA888) Model Year 2009 - 2011" and applies to A4/A5/A6 etc, so that's 2nd gen EA888 (which is the first TFSI engine using Valvelift). This issue is well known, it's the piston rings, but we're talking EA888 3G (3rd gen) here because that's what the OP owns. From your second link:
Remember the EA888 3G was introduced around 2012/2013.
Had a quick look into these. Couldn't see any real issues there. Short threads started by someone asking if it's normal that he has to top-up half a quart after 10000 mls. Sorry, I can't take that for serious.
Again, your A4 did not suffer from any oil use that can be called "excessive" or "abnormal". 100 ml for 1000 km is pretty normal across the industry and that wasn't even measured in a controlled environment. Please notice I'm not talking about "spec". In the past Audi used to say up to 1 l/1000 km is "within spec". However that's a completely different number than what you think is "abnormal". Actually you were very far from that number.
