OIL CONSUMPTION! Every 7000 miles from oil change my 3.0 TFSI needs a quart, but not 300 miles earlier when I checked it last! WTH? Where does it disappear to all of a sudden? I mean, I pretty much drive like a grandpa! seriously. Audi tops it off, no worries, but my Yota never did that, with 290,000 miles on it! Yours?

Got my A8 about a month ago, topped it up after 2 weeks , and now the warning is back on. 1000 miles. I’m at 58 K. Car is still under Carvana warranty, this should be covered, right? And I should take to an Audi dealership? 3.0 T btw.

Well, that is something you will have to speak to carvana about.
Audi says oil consumption, even heavy use, is totally normal for superchaged engines! I call bullsh*t! But most all Audis do.
I am abusing oil at almost 600 miles to add.
I was hoping that the flush and different oil and additives would help. I may just as well switch back to castrol.

I just topped it up and hit the trip. Let’s see exactly how long it lasts. I had an M5 a few years ago (V10) and it also consumed a little more than I had liked. I switched to Liqui Moly and it decreased significantly. Might have to try that.

There is a TSB for certain years of the Q7 that Audi will replace your PCV for free if the VIN qualifies. Will link when I find it.

Mine is 1l (bit more than a quart) per 900km.
It can leak, you may have bad pcv valve (run vcds scanner to see errors). But really seems normal according to the owner's manual.
I would dream to have your consumption.
Technicians warn against capricious 3.0 tfsi and advise to run away from it.

Funny, every time in the past when I asked anyone really at the dealerships why they burn so much oil, from the first month I owned this car, and they gave me the "turbos use oil" bulls**t line, I ask is their someone smart that works here that could better answer my question? Which pisses them off, but c'mon man, I would rather hear the truth, I don't know!

This was a great explanation and understandable! And he is right, although I do love this car, I would not own another, I don't believe.

The problem should have been addressed by the manufacturer. It really is unacceptable as far as quality standards go, for Audi/VW/Porsche to produce engines like that.
