Hello,
I have a 2016 Audi A6 and was wondering. It starting using oil at 62,000 miles. At 400-900 miles its a full quart low and needs to be topped off. Its done this a total of 4 times now and the car is at 65,000 miles. I've read the the different articles saying that its normal for these cars to burn a quart every 2,000-8,000 miles or so is what I've been seeing on average but it seems mine is a little above that. The dealer is currently running an oil consumption test on the car now for 1,000 miles to see if it does it again which if it all goes the way it has been it will. The dealer is not saying what they want to do next. Any ideas of what I should say to them? Any suggestions are greatly appreciated.

2.0L or 3.0L?

3.0. Also The car has been thoroughly checked and there are no external leaks.

The newer 3.0T's had problems with the oil separator failing causing oil consumption. It will set a soft code in the ECM but not turn the check engine light on. A quick and easy test is to pull the oil cap off with it running and see how much vacuum is in the crankcase. If it takes a ton of effort to pull the cap off and sounds like a shopvac then the oil separator under the supercharger will need replaced.

Replacing the PCV valve integrated to the oil separator unit will not stop oil consumption. I replaced mine and nothing changed. Check videos below.

Hello,
Actually I haven't had any problems since I got it replaced. I've put about 15,000 miles on it since it was done
and good to go!!!
Hope you have the same luck!!!!
