The lower window frame (the black thing with the hood) was changed at me. is a misconstruction and slipped constantly from the window. the best is the service reset at citroen. keep the trip button pressed, ignition on (without starting), 10 seconds wait. already you have 30,000 new kilometers free. is actually completely for the hugo (with me you forgot the reset during the delivery, therefore the stupid goods service before the time indicated, then explain the master in the workshop told me how I could solve the problem).
