 This is for all consumers having Oil Consumption issues. I purchased my 07 A4 used with 54,500 miles on it.Right away I noticed the oil consumption problem.I tracked the consumption for about 10,000 miles and made sure the dealership knew the mileage everytime I had to put another qt in.The light was coming on down to just less than a 1000 miles to add a qt.I paid the out of pocket expense and the test came back that there was an issue.Audi Corp covered 85% of the repair and the dealership I purchased from, Elk Grove Audi, covered the remaining balance.Audi replaced the Piston rings.I now have close to 8000 miles since replacement and holding strong. Added 1 qt at 5000 mi.
