Switch fuses (WTF?) at the Peugeot

Dear forum, my Peugeot 607 now celebrates my 1-year anniversary and it drives like a lion. Only occasionally error messages like “airbag defective” or recently I can not hear my interlocutor at the telephone system. He however can understand me very well. I thought, maybe it is because of the fuses! When I then looked in the manual, I hit a light blow as I saw the fuses (see photo). Can it be that the seller did not want to use these correctly and adequately???? I know unfortunately not so well, but there are a few fuses missing here or? A week before the purchase, actually still worked, that the side mirrors snapped in randomly, if one shut down the car. When I then bought the car, it did not go any more. Only the doors, luggage room allowed to be closed. Can it be that he has randomly inserted a few fuses? Is that so correct? Maybe this would explain that my seat heating does not work, side mirrors do not fold in and I do not get the error message, if I want to be quite happy here, if I want a security link!
