hello friends, I have unfortunately a small problem with the front window. at the bottom right, at the transition from the a-pillar to the kotflügel I have a crack. at first about 10 cm and gradually about 30 cm. there is no stone damage visible. my question: has someone of you had this problem before and if so, you can have the disc changed to kulanz. the car is middle-live 5 years old. many thanks for your help… gruß tt 83
