2008 Skoda Octavia electric windows opening when car is locked

There are two main causes of this problem which is common across the Skoda and VW ranges. The problem is to do with the global opening "feature" which allows you to open all the windows by a long press of the lock button on your remote control. If you inadvertently press the button in your pocket this will unlock the doors and open the windows. If none of the doors are opened within a set period (40 secs I think) the doors re-lock but the windows will remain open. If you are sure you are not pressing the button then it could be water ingress in one of the front window control units located in the front doors. The door control unit is mounted at an angle that allows any water that has entered the top of the door to sit in the top of the connector. This eventually corrodes and causes false signals within the electronics. Corroded connections will be obvious and will need thorough cleaning and treating with petroleum jelly or silicone grease to prevent recurrence of the problem.

Finally the global opening feature can be programmed out by your dealer if all else fails or you don't want it anyway.

Known fault on that car , this explains ,


Re: Octavia Electric windows opening randomly

I bought a 2003 Octavia in 2006 and had a similar problem about a year later. I would find the windows open in the morning sometimes - or they would open/close at random - sometimes when I was driving! Pretty scary..... I took it to the dealer and they said that there was a known fault whereby the central doors/windows control mechanism (in the driver's door) would get damp and some of the terminals would corrode and cause intermittent problems. I had to get a new control unit and the problem went away. Sometimes, individual pins within the unit may be replaced (depending on how bad it is) but you'd have to get advice on this.....
