2012 Audi A4 UNKNOWN OR OTHER,ENGINE

THIS CAR HAS A MASSIVE OIL CONSUMPTION ISSUE. A WEEK AFTER HAVING AN OIL CHANGE THE LOW OIL LIGHT COMES ON AFTER APPROXIMATE 150 MILES OF DRIVING. I STARTED HAPPENING IN FEBRUARY OF 2017 SHORTLY AFTER THE ENGINE MALFUNCTION LIGHT CAME ON . I TOOK IT TO THE DEALERSHIP AND AFTER THEY RAN THE REQUIRED TESTS THAT FAILED, WAS TOLD THAT AUDI PUT THE WRONG ENGINE IN THE CAR AND THAT I WOULD HAVE TO PAY $8K FOR THEM TO FIX IT. THIS IS NOT MY PROBLEM, IT IS AUDI'S BECAUSE IT IS THE SAME ISSUE THAT THEY SETTLED IN A LAWSUIT YEARS PRIOR. IT IS NERVE-WRACKING TO DRIVE BECAUSE, I NEVER KNOW HOW MUCH OIL IS IN THE CAR.

PISTON RINGS CAR IS SMOKING AND OIL IS COMING OUT OF THE MUFFLER THE CAR HAVE LAST THEN 100K MILEAGE

EXCESSIVE OIL CONSUMPTION ISSUES, CHECK ENGINE LIGHT IS ON AND AUDI WANTS TO CHARGE ME $12,000 TO REPAIR THE OIL CONSUMPTION DUE TO THEIR BEING DAMAGE TO MY PISTON RINGS. I AM THE SECOND OWNER OF THIS CAR. DURING THE TIME THAT THE FIRST OWNER HAD THE VEHICLE THERE WAS A CLASS ACTION LAW SUIT THAT HAD BEEN FILED AND SETTLED AGAINST AUDI DO TO THE MANUFACTURER MALFUNCTION WHICH CAUSED THE EXCESSIVE OIL CONSUMPTION PROBLEMS WITH THE VEHICLE. BY THE TIME I BECAME THE OWNER THE SUITE HAD ALREADY SETTLED. AT THIS POINT I DON'T KNOW WHAT TO DO.
