Morning Gabriel

Welcome to the Forum

The obvious is have you had passengers in and out of the back ? If not the are the windows closed right up ? If they are then check the door seals and make sure the membrane behind the door cards are in place and not torn or badly fitted.

Thank you, I’m happy to be here.

There was no passengers in and out as on the back I have to child seats, the windows are  up close and locked for safety.  Now I’m not an expert so what you mean by the membrane behind the door cards?is that behind the doors panels, I have to take them off and check ?
