Girenti whistle

They just called me from the workshop ... Apparently my insurance company considers that it is not the coup and those of the workshop do not know how to tell me what it is ... that they would know how to tell me once they disassemble the distribution strap but then they have to put another new one,
is this normal?

It deposes directly from the workshop's work policy, but if your question is whether it should change a disassembled, it is not necessary. What they would do is get the strap of elements and give the vehicle to make if the beep disappears if the distribution does not uncover it to seek the prossity of the noise.
