206 sanfourlu vehicles take rainwater to BSI part

Friends got water in my car's BSI box, we can't figure out where and how it got in, even if I repair or replace it, it is very likely to repeat the failure in heavy rain, nothing visible, but BSI also had rainwater, it was cleared, it rained heavily. .Acillll Help ....

Check the windscreen seals + Door seals.

windscreen wicks are intact, door wicks are intact

I think the cables coming out of BSI go to the front hood section of the vehicle, I wonder if it takes water from those sections, if it gets from those sections, I can close it with silicone.

???????????????????

When we removed the bonnet from the service, a master spoke about the wick just above the wiper motor, and this could be a problem if it was decayed.

I recently called a peugeot service, when you lift the hood, they said that there are sieves on the left side.

Friends say that water is coming in my BSI box. They can't say anything definite, we pour water until the car, no way, no water is going to the section where the BSI box is, it is not mind how it got water.
