Ceramic brakes

Moin all together, I’m new here and I would like to ask you a question! Maybe someone can help me! I bought an Audi V10 plus 1 months ago BJ 2015 which still has a warranty until 2020… When driving home I noticed that the brake gives away grinding noise and the gearbox makes howling noises:-( I called my salesman and he said that I should drive to the workshop on site to check it out! It would be Gara I drove directly to the AZ and reported the errors! But I only got an appointment in a month! Now the car was finally on and the workshop found a fault with the brake system (brake pads in front would be defective bubble formation) That was reported Audi the say no guarantee!!!!! The dealer (where I bought the car) would like to take over only half He meant that I drove about 900 km I could see the documents What totally stupid is that I just drove the federal road! Fun car …. Who knows how to behave?
