Alfa Romeo 159 (57) - Windows opening on own (possibly resolved) :-)
After buying a second hand Alfa Romeo 159 I found out that the spare key fob wasn't working... I discovered that there was no battery was in it, so I got one put in.
After that, One morning I woke up to find all the windows down and the snow coming in the car.
This happened a few times when ever I parked up at the house. But not when visiting friends, family, or out shopping.
Then I thought I will use the spare key fob and walk up to the car... bleep.. windows down!!.
So I took out the battery of the spare key fob... Guess what... the Windows haven't come down yet, without me wanting them down, this has now been a week, and the car has been perfect.
I guess Alfa's get confused with two working key fobs??
Also I keep the key fob in a glasses case, just in case as you can press a button on the fob walk away and the windows come down.
Do try only having one battery in one key fob.
I hope this helps.
