This is strange that storage lock and gas door are closed/open in the same time.
In my car this was not work ok (gas door always closed, I must opened from trunk).
But I fix this problem. In vacuum pump is electric valve. Normaly always open only for trunk and doors (gas door and storage closed). I make that all open.
Now doors, trunk, gas door and storage are close or open in the same time.
Anybody can explain how it works oryginaly?
