Have you just got one switch or two? Some of the seats have two like my cordy, you might be changing the wrong one.

this white i changed

this "blue" is too brake switch or something else?
it can also be bad?

Your pics didn't work but they should now as you've cleared the 15 post mark but here's my switches and yeh it could be either of them.

yes they are

blue (UP)

white (DOWN)

i was changing this white (DOWN).

The blue switch is what?

I think the bottom one does the brakes lights and the top one has something to do with the ecu, it tells the ecu that you've pressed the pedal, I've read some threads on other forums and it sounds complicated, they both have to match or it throws codes etc. Maybe either the blue switch is knackered or they're not adjusted correctly.
