I OWNED THE 2009 AUDI A4 QUATTOR. MY CAR HAS A SERIOUS OIL CONSUMPTION PROBLEM AROUND 350 MILES PER QT. I DID A LOT OF RESEARCH ONLINE.

I HAVE OBTAINED THIS CAR AS A USED CAR. ENGINE OIL WAS CHANGED ONE WEEK AFTER I HAVE THE CAR AT A MECHANIC SHOP. THREE WEEKS (ABOUT 500MILES DRIVING) LATER, A LOW ENGINE OIL ALARM SOUNDED.

I HAVE OBTAINED THIS CAR AS A USED CAR. ENGINE OIL WAS CHANGED ONE WEEK AFTER I HAVE THE CAR AT A MECHANIC SHOP. THREE WEEKS (ABOUT 500MILES DRIVING) LATER, A LOW ENGINE OIL ALARM SOUNDED. I BROUGHT THE CAR BACK TO THE SAME MECHANIC SHOP AND ADD A QUART OF OIL TO THE ENGINE. A COUPLE WEEKS LATER, I WAS DRIVING THE CAR TO A ROAD TRIP. THE LOW OIL ALARM SOUNDED AGAIN. THIS WAS IN THE MIDDLE OF MY ROAD TRIP WHEN I WAS DRIVING IN THE HIGHWAY (ABOUT 500MILES SINCE LAST OIL ADDITION) AT ABOUT 75MPH. I HAVE TO GET OFF THE HIGH WAY RIGHT AWAY AND WENT TO A LOCAL MECHANIC SHOP TO TOP OFF THE OIL. I WAS TOLD BY A MECHANIC THAT THIS IS DANGEROUS BECAUSE IF I COULDN?T FIND A MECHANIC SHOP IN TIME TO ADD MORE ENGINE OIL, THE ENGINE WOULD HAVE BEEN OVERHEATED, LOCKED, AND FORCED TO STOP RIGHT AWAY. UNDER THIS SCENARIO, A SERIOUS COLLISION WITH THE CARS BEHIND OR NEXT TO ME MIGHT BE CAUSED IF DRIVING ON THE HIGHWAY. UPON RESEARCH, IT WAS DISCOVERED THAT THIS ABNORMAL AMOUNT OF ENGINE OIL CONSUMPTION HAS BEEN A COMMON PROBLEM/COMPLAINT IN THIS MODEL OF CAR DUE TO THE DEFECTS IN THE PISTON RINGS. IN MOST CASES, THE PISTON RINGS WERE REPLACED UNDER THE MANUFACTURER WARRANTY. MY CAR IS JUST OUT OF WARRANTY WITH 57K MILES ON IT. THE DEALER SHOULD BE RESPONSIBLE FIXING THIS PROBLEM AS IT IS A SERIOUS SAFETY PROBLEM AND IT WAS DEFECTED FROM THE MANUFACTURER. *TR
