Hey everyone, I have a 2010 A6 3.0 Quattro supercharger. I just bought it used at 125,000 miles. The car runs good and haven’t really had any problems besides it is going through oil like crazy. I have read that these cars use a lot of oil, but when I accelerate or sometimes just starting the car up there is black smoke coming from the exhuast. I ran my finger across it and there was oil on it. I’m a little nervous there is something wrong with the piston rings or valve but is this normal for a supercharger? I’m not looking to drop thousands into this car.
