We know the thermostat and water pump wouldn't do anything for oil consumption. As for the PCV, sometimes it requires a software update to the ECU for vacuum pressure as updated revisions of the PCV come out (I know this was the case on the 2.0Ts). If it was done at a local shop (non-dealer) and it does require a software update, then it may not be working optimally.

Hi

I’m having the same issue with my 2017 3T Q7. How did you get assistance with the repair?

We have a low mileage 2019 A-7 and Audi North Houston claims our car is making up the story.

An Audi owner in Germany solved the problem with a special blend of motor oil ... and it works.

That is correct re Lucas oil stabilizer (I had forgotten the brand).

In the meantime, it's very frustrating that Audi and their dealers cover up the problem .. including their worldwide defective alternator problem which includes a major shortage of replacements (and no after-market replacements).

Someone once said that the true crime was not the crime itself but was the covering up of the crime aka ongoing excessive oil consumption and worldwide defective alternator problems.

In full disclosure ... I was stupid to purchase a second high-dollar German car. I should have known given its owner. Volkswagen was built during World War II as "the people's car".

Unfortunately the only solution is a complete piston replacement, which included removal and installation of engine, replacing all pistons,all associated gaskets, o-rings and spark plugs. We were fortunate to have a good relationship with our dealership and ultimately got the approval from Audi NA to perform a goodwill replacement at no charge. All work was warranted for 1 year/ 12,000 miles. We have only driven~ 2,000 miles So far, no oil burn. Car was out of service for over a month but we’re happy for the support the dealership gave us, including a loaner. I got the impression that not all vehicles would be approved for this “good will” treatment but I’ll take it and appreciate it. Would have been around $20k I was told. Definitely worth pursuing with your dealer if you have this issue.
