Hi guys. I am a newbie and have a 1999 Lupo 1.4S (green!). Unfortunately experiencing a couple of problems: 1. The central door locking mechanism starts clicking on and off while driving along. The door lock knobs don't move but you can hear the mechanism clicking away like mad; and 2. When unlocking the car both electric windows roll down. Once inside the car they can be put back up with the switches as per normal. Any thoughts much appreciated Cheers Andrew
