Dear guys, I have an Octavia Mk3 (5E) Sedan from 2013 (1.2 TSI 77 kW). My problem is that the rear parking aid isn't working and I want to change the buzzer. I already demounted both B-pillar trims and the near side C-Pillar trim. I couldn't find the buzzer. Can anyone please help me locating the rear parking aid buzzer so I can replace it? I appreciate your help a lot. Thanks
