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. Also, when I type Audi A4 2009, then I can find a lot of people are talking about the oil consumption problem. And I did research from my friends who own the A4 and ask about some information. I know many, many the same issues also in china, taiwan, german and usa. Therefore, I cannot understand why this car did not recall!!! or help us who owned the A4. I got some information from two different car shop. The data shows Audi A4 and S5 between 2009-2011 have a lot of issue about the oil consumption problem in the usa. I know the car is not recall, but is there any way can help the Audi owner to keep this car?

Recently done oil change with synthetic oil (Audi recommended) which should last for 10,000 miles before another oil change is needed. Unfortunately after a month and half of driving oil levels are showing half of the oil gone. Engine is making noise and lot of CO2 being clogged up. Running heavy causes to use lot of fuel. Feels as if engine may get too hot after eating up excess amount of oil.

The car burns 1 quart of oil every 200 miles. Its a well known issue with the 2009 A4 2.0T millions of people are burning gallons of oil in these cars. Its a shame that Audi is sweeping this issue under the rug. These cars need recalled.

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.
