 I've had my A4 back to the dealer 4 times for excessive oil consumption. They've gone as far as replacing all of my pistons/ring (took 30 days) to complete and it still consumes about 1 qt. every 1500 miles. Power steering hose is on recall so had that repair completed at the same time and had to take it back again for the power steering hose. This car looks awesome but just isn't very well built I have confronted Audi and they say it is NORMAL for a car to burn up to 1 qt. every 1000 MILES. This would be 9 quarts of oil between oil changes. My 1997 Explorer with 185K miles didn't go through oil like this.
