Skoda Fabia II owners from the ACPR often complain about the click of a gas pedal in box D during the start of the movement.
According to the explanation of the official dealer's service, the clicks release the blocking mechanism of the box at the moment of motion. I mean, the sound isn't from the pedal, but from the ACPR.
According to another explanation, a loud metal click reproduces a relay that activates the airbags of the car during the movement.
