Re Alfa Spider - My regulator was replaced with genuine Alfa Part (or so I was told). Window works but in reverse of what it should - ie instead of going down few cms when opening/shutting door window will go fully up down when opening & shutting door. I can use switch to move window up and down slightly but need to close door to get it to go fully up if it has been opened fully. The centre roof opening switch will only make the window go down and then will not operate the roof as it senses an "error". I have done the reset but note in my manual that it should have been done firstly with the doors closed. Unfortunately the mechanics worked on it with the door open. I have lookoed thru forums and found plenty of resets that worked but nothing works for me. Do I have to undo the battery or dismantle the door and reassemble things to get it to reset?
