FYI, I have to tell Audi customers (at least 2 a day) brake noise is considered normal by Audi, it does not hinder performance by their standards. They actually have a brochure to give to customers explaining why and when it may happen. This is mostly because of the metallic brakes, and the metal contact in them, you have ceramic and I would not think the same applies, I have EPC green and have no noise.
FYI
According to the Audi brochure it says;
All sound is caused by vibration. The squeeling sound yopu may hear when you apply your brakes is usually caused by the brake pads vibrating in their mounts-which is a perfectly normal condition. The phenomenom is most prevelant in vehicles with front disc brakes. front brakes are responsible for a high percentage of the stopping action. Disc brakes by their design are more likely to have the pads vibrate.
Trace squeek/squeel sound - medium speeds-light to medium brake pressure
Grinding sound - caused by trace corrosion-during first few stops after vehicle sits
Groan sound - may be heard on quick stops or allowing vehicle to move forward slowly from a stop.
Although I have searched by google for brake noise, I have not found anything else that says it is normal, other than what I have from Audi/VW??????
