My 2010 A5 has only 17k miles bought as CPO. Car develops a weekly buildup of smudge on the wheels, especially on the insides. Driving around this week in the rain produced a whole lot more, including spatters of grease on both the front left wheel and driver's door. I didn't notice any grease on the passenger side but all the wheels collected an amazing amount of black junk.

Is this standard behaviour with Audi brake pads?

Could my front left CV boot also be leaking and if so would it be covered under warranty?

Thanks in advance.
